参照图2，本发明第一实施例提供一种声纹定位方法的流程示意图。该实施例中，所述声纹定位方法包括以下步骤：2, a first embodiment of the present invention provides a flow chart of a voiceprint positioning method. In this embodiment, the voiceprint positioning method includes the following steps:
步骤S10，获取声音接收装置组接收用户基于预设二维码发送的次声波的时间差信息；Step S10, obtaining time difference information of the sound receiving device group receiving the infrasound waves sent by the user based on the preset QR code;
本实施例中声纹定位方法应用于声纹定位系统，以下将声纹定位系统简称为系统，系统中包括服务器与由多个声音接收装置组成的声音接收装置组，服务器与多个声音接收装置均建立了连接关系，多个声音接收装置设置于同一区域范围内的不同位置，其中服务器是计算机的一种，在网络中为其它客户机提供计算或者应用服务，声音接收装置用于接收用户预设终端发出的次声波，预设终端在本实施例中可以为智能手机、平板电脑等移动终端。In this embodiment, the voiceprint positioning method is applied to a voiceprint positioning system, which is hereinafter referred to as the system. The system includes a server and a sound receiving device group consisting of multiple sound receiving devices. The server and the multiple sound receiving devices have established a connection relationship. The multiple sound receiving devices are arranged at different locations within the same area. The server is a type of computer that provides computing or application services to other clients in the network. The sound receiving device is used to receive infrasound waves emitted by a user's preset terminal. The preset terminal in this embodiment can be a mobile terminal such as a smart phone or a tablet computer.
可以理解地，日常的定位手段主要是基于GPS(Global Positioning System，全球定位系统)定位，以及AGPS(Assisted Global Positioning System，辅助全球卫星定位系统)移动基站辅助定位。但是当人们处于障碍物遮挡下，比如地下室、高架下面等场合下，通常会出现接收不到GPS信号和移动基站信号的情况。在这种情况下，人们很难再进行GPS定位和AGPS定位，由于不能进行精准定位，使人们进入失联状态，进而对人们的生活带来极大的困扰。在此基础上，本申请提出一种声纹定位方法，在上述场合中放置预设二维码供用户扫描并发送次声波，然后声纹定位系统获取声音接收装置组接收次声波的时间差信息并结合声音接收装置组的位置信息计算出用户的目标位置信息，即使在障碍物遮挡下也能通过扫描预设二维码发送的次声波快速获取用户的目标位置信息，实现对用户进行精准定位。Understandably, daily positioning means are mainly based on GPS (Global Positioning System) positioning and AGPS (Assisted Global Positioning System) mobile base station assisted positioning. However, when people are blocked by obstacles, such as in basements, under elevated roads, etc., they usually cannot receive GPS signals and mobile base station signals. In this case, it is difficult for people to perform GPS positioning and AGPS positioning. Since accurate positioning cannot be performed, people are out of touch, which brings great trouble to people's lives. On this basis, the present application proposes a voiceprint positioning method, in which a preset QR code is placed in the above occasions for users to scan and send infrasound waves, and then the voiceprint positioning system obtains the time difference information of the sound receiving device group receiving the infrasound waves and calculates the user's target location information in combination with the location information of the sound receiving device group. Even under the blockage of obstacles, the user's target location information can be quickly obtained by scanning the infrasound waves sent by the preset QR code, so as to achieve accurate positioning of the user.
进一步地，为了能够使得人们在地下室、高架下面等处于障碍物遮挡下的场合中进行精准定位，本实施例在地下室、高架下面等处于障碍物遮挡下的场合中张贴预设二维码，具体地，可以在地下室等场合的入口、休息区以及地面上张贴预设二维码，以使用户在具有定位需求时，可以通过扫描预设二维码生成并发送次声波，其中预设二维码中设置有次声波发生程序，用于生成次声波；并且，为了使得用户扫描预设二维码后，可以顺利地发出次声波，若地下室、高架下面等处于障碍物遮挡下的场合中网络信号较差，则在该场合中部署无线网络，例如WI-FI(无线上网)等。进一步地，在用户通过预设终端扫描预设二维码并发送次声波后，声音接收装置组中的多个声音接收装置分别对次声波进行接收，并将接收到次声波的接收时间以及次声波中的身份标识信息发送至服务器，其中身份标识信息用于对用户进行唯一标识。进一步地，服务器接收声音接收装置组中各声音接收装置发送的次声波的接收时间，得到多个接收时间，再将多个接收时间进行两两差值运算，得到各接收时间之间的多个时间差值并形成时间差信息，以根据时间差信息与声音接收装置组的位置信息确定出用户的目标位置信息，便于对用户进行精准定位。Further, in order to enable people to accurately locate in places such as basements and under elevated roads, which are blocked by obstacles, the present embodiment posts preset QR codes in places such as basements and under elevated roads, and specifically, preset QR codes can be posted at the entrance, rest area, and on the ground in places such as basements, so that when users have positioning needs, they can generate and send infrasound waves by scanning the preset QR codes, wherein the preset QR codes are provided with an infrasound wave generating program for generating infrasound waves; and, in order to enable users to smoothly send out infrasound waves after scanning the preset QR codes, if the network signal is poor in places such as basements and under elevated roads, which are blocked by obstacles, a wireless network, such as WI-FI (wireless Internet access), is deployed in the places. Further, after the user scans the preset QR code and sends the infrasound wave through the preset terminal, the multiple sound receiving devices in the sound receiving device group receive the infrasound wave respectively, and send the receiving time of the received infrasound wave and the identity information in the infrasound wave to the server, wherein the identity information is used to uniquely identify the user. Furthermore, the server receives the reception time of the infrasound waves sent by each sound receiving device in the sound receiving device group, obtains multiple reception times, and then performs pairwise difference operations on the multiple reception times to obtain multiple time differences between the reception times and form time difference information, so as to determine the user's target position information based on the time difference information and the position information of the sound receiving device group, thereby facilitating accurate positioning of the user.
进一步地，所述获取声音接收装置组接收用户基于预设二维码发送的次声波的时间差信息的步骤之前，还包括：Furthermore, before the step of obtaining the time difference information of the infrasound waves received by the sound receiving device group based on the preset QR code sent by the user, it also includes:
步骤A1，分别与声音接收装置组中的多个声音接收装置建立通信连接，以与多个所述声音接收装置进行交互。Step A1: establish communication connections with multiple sound receiving devices in the sound receiving device group respectively to interact with the multiple sound receiving devices.
进一步地，为了使服务器能够及时与声音接收装置组中的多个声音接收装置进行交互，服务器还需要分别与声音接收装置组中的多个声音接收装置建立通信连接，具体地，服务器可以通过无线网络(如WI-FI、局域网等)分别与声音接收装置组中的多个声音接收装置建立通信连接，以在与声音接收装置组中的多个声音接收装置建立通信连接后，从声音接收装置组中获取各声音接收装置接收次声波的时间信息与身份标识信息，便于对用户进行精准定位。Furthermore, in order to enable the server to interact with multiple sound receiving devices in the sound receiving device group in a timely manner, the server also needs to establish communication connections with the multiple sound receiving devices in the sound receiving device group respectively. Specifically, the server can establish communication connections with the multiple sound receiving devices in the sound receiving device group respectively through a wireless network (such as WI-FI, local area network, etc.) so that after establishing a communication connection with the multiple sound receiving devices in the sound receiving device group, the server can obtain the time information and identity identification information of each sound receiving device receiving the infrasound wave from the sound receiving device group, so as to facilitate accurate positioning of the user.
步骤S20，获取所述声音接收装置组的位置信息，根据所述位置信息与所述时间差信息确定所述用户的目标位置信息；Step S20, obtaining the position information of the sound receiving device group, and determining the target position information of the user according to the position information and the time difference information;
可以理解地，声音接收装置组中各声音接收装置均设置有一个具体的位置信息，例如在地下室内设置的声音接收装置，设置有二维的位置信息以及声音接收装置所在的纵向信息(例如声音接收装置设置的楼层)，以形成立体的位置信息。进一步地，服务器根据与声音接收装置组中各声音接收装置的连接关系，从各声音接收装置中获取各声音接收装置分别对应的位置信息。在获取到声音接收装置组中各声音接收装置的位置信息后，服务器通过获取的位置信息与时间差信息进行计算，以确定出用户的目标位置信息，具体地，服务器根据两两声音接收装置之间接收次声波的时间差，以及两个声音接收装置与次声波发送位置之间的距离之差，通过建立方程组并进行求解，计算出用户的位置信息，以对用户进行精准定位。It can be understood that each sound receiving device in the sound receiving device group is provided with a specific location information. For example, a sound receiving device set in a basement is provided with two-dimensional location information and longitudinal information of the sound receiving device (for example, the floor where the sound receiving device is set) to form three-dimensional location information. Further, the server obtains the location information corresponding to each sound receiving device from each sound receiving device according to the connection relationship with each sound receiving device in the sound receiving device group. After obtaining the location information of each sound receiving device in the sound receiving device group, the server calculates the target location information of the user through the obtained location information and time difference information. Specifically, the server calculates the user's location information by establishing a set of equations and solving them according to the time difference of receiving infrasound waves between two sound receiving devices and the difference in distance between the two sound receiving devices and the location where the infrasound waves are sent, so as to accurately locate the user.
步骤S30，根据所述目标位置信息向所述用户发送定位反馈信息。Step S30: Send positioning feedback information to the user according to the target location information.
在计算出用户的目标位置信息后，由于计算得到目标位置信息为二维位置信息，服务器根据各声音接收装置位置信息中的纵向信息，对目标位置信息进行调整，得到更精确的目标位置信息。进一步地，服务器接收各声音接收装置从次声波中识别并发送的身份标识信息，将身份标识信息与得到的精确目标位置信息生成为定位反馈信息，并将定位反馈信息发送至用户的预设终端中，以便于用户根据接收到的定位反馈信息确定自己所处的位置。可以理解地，为确保用户信息的安全性，服务器在向用户发送定位反馈信息之前，还可以对从各声音接收装置中接收的身份标识信息进行校验，确定多个身份标识信息是否相同，在多个身份标识信息均相同时才根据身份标识信息向用户发送定位反馈信息。After calculating the user's target location information, since the calculated target location information is two-dimensional location information, the server adjusts the target location information according to the longitudinal information in the location information of each sound receiving device to obtain more accurate target location information. Further, the server receives the identity information identified and sent by each sound receiving device from the infrasound wave, generates positioning feedback information with the identity information and the obtained accurate target location information, and sends the positioning feedback information to the user's preset terminal, so that the user can determine his or her location based on the received positioning feedback information. It can be understood that in order to ensure the security of user information, before sending the positioning feedback information to the user, the server can also verify the identity information received from each sound receiving device to determine whether multiple identity information is the same, and only send positioning feedback information to the user based on the identity information when multiple identity information are the same.

可以理解地，当用户通过预设终端扫描后，用户需要根据实际使用环境选择打开方式，例如可以打开一个网页，或者启动一个轻应用，或者支付宝、微信、头条等第三方小程序来请求播放表征声纹的带有用户信息的次声波，并将用户信息作为请求信息生成次声波发送请求，并将次声波发送请求发送至服务器，其中网页需要用户输入的手机号等用户信息来发送请求，第三方小程序通过用户授权的用户信息来发送请求。进一步地，为了及时响应用户的定位需求，服务器实时检测是否存在用户通过预设终端扫描预设二维码发送的次声波发送请求，若存在次声波发送请求，则对次声波发送请求进行接收，并对次声波发送请求进行解析，得到次声波发送请求中包含作为请求信息的用户信息，为了对用户进行区分，服务器根据请求信息生成身份标识信息，以对用户进行唯一标识，便于对不同的用户进行区分。进一步地，服务器根据接收预设终端发送次声波发送请求时的路径，将身份标识信息作为确认指令发送至预设终端，以供预设终端基于身份标识信息生成并发送次声波，使得服务器在确定用户的目标位置信息时可以对不同用户进行区分，提高定位的准确性。It is understandable that after the user scans through the preset terminal, the user needs to choose the opening method according to the actual use environment, for example, a web page can be opened, or a light application can be started, or a third-party applet such as Alipay, WeChat, Toutiao, etc. to request to play the infrasound with user information representing the voiceprint, and the user information is used as the request information to generate an infrasound sending request, and the infrasound sending request is sent to the server, wherein the web page requires the user to enter the mobile phone number and other user information to send the request, and the third-party applet sends the request through the user information authorized by the user. Further, in order to respond to the user's positioning needs in a timely manner, the server detects in real time whether there is an infrasound sending request sent by the user through the preset terminal scanning the preset QR code. If there is an infrasound sending request, the infrasound sending request is received and parsed to obtain the user information contained in the infrasound sending request as the request information. In order to distinguish users, the server generates identity information according to the request information to uniquely identify the user, so as to distinguish different users. Furthermore, the server sends the identity information as a confirmation instruction to the preset terminal according to the path of receiving the infrasound wave sending request from the preset terminal, so that the preset terminal can generate and send infrasound based on the identity information, so that the server can distinguish different users when determining the user's target location information, thereby improving the accuracy of positioning.
本实施例在获取声音接收装置组接收用户基于预设二维码发送的次声波的时间差信息之前，根据用户发送的次声波发送请求生成身份标识信息，并将身份标识信息作为确认指令发送至用户的预设终端，使得预设终端可以基于身份标识信息生成并发送次声波，以进行用户目标位置信息的确定，实现对用户进行精准定位。Before obtaining the time difference information of the sound receiving device group receiving the infrasound waves sent by the user based on the preset QR code, this embodiment generates identity identification information according to the infrasound wave sending request sent by the user, and sends the identity identification information as a confirmation instruction to the user's preset terminal, so that the preset terminal can generate and send infrasound waves based on the identity identification information to determine the user's target position information and realize accurate positioning of the user.
进一步地，参照图4，基于本发明声纹定位方法的第一实施例，提出本发明声纹定位方法的第三实施例，在第三实施例中，所述根据所述位置信息与所述时间差信息确定所述用户的目标位置信息的步骤包括：Further, referring to FIG. 4 , based on the first embodiment of the voiceprint positioning method of the present invention, a third embodiment of the voiceprint positioning method of the present invention is proposed. In the third embodiment, the step of determining the target location information of the user according to the location information and the time difference information includes:
步骤S21，根据所述位置信息与所述时间差信息生成方程组；Step S21, generating a set of equations according to the position information and the time difference information;
步骤S22，对所述方程组进行求解，得到所述用户的目标位置信息。Step S22, solving the equation group to obtain the target location information of the user.
在获取声音接收装置中各声音接收装置的位置信息后，服务器首先根据声音传播速度与多个声音接收装置接收次声波的时间差信息，计算得到由时间差形成的多个距离信息，再根据多个距离信息与各声音接收装置的位置信息，生成方程组。在生成方程组后，服务器调用内部存储器中设置的解方程组算法，通过解方程组算法对方程组进行求解，计算出用户的目标位置信息，实现对用户的精准定位。After obtaining the position information of each sound receiving device in the sound receiving device, the server first calculates multiple distance information formed by the time difference according to the sound propagation speed and the time difference information of the multiple sound receiving devices receiving the infrasound waves, and then generates a set of equations according to the multiple distance information and the position information of each sound receiving device. After generating the set of equations, the server calls the set of equations solving algorithm set in the internal memory, solves the set of equations through the set of equations solving algorithm, calculates the user's target position information, and realizes accurate positioning of the user.
进一步地，所述根据所述位置信息与所述时间差信息生成方程组的步骤包括：Furthermore, the step of generating a set of equations according to the position information and the time difference information includes:
步骤S211，获取声音传播速度，根据所述声音传播速度与所述时间差信息，计算得到由时间差形成的距离信息；Step S211, obtaining a sound propagation speed, and calculating distance information formed by the time difference according to the sound propagation speed and the time difference information;
步骤S212，根据所述距离信息与所述位置信息，生成方程组。Step S212, generating a set of equations according to the distance information and the position information.
进一步地，服务器可以基于无线网络获取声音传播速度，也可以从内部存储器中获取声音传播速度；在得到声音传播速度后，服务器根据距离计算公式与声音传播速度，分别计算出各声音接收装置接收次声波时的时间差所形成的距离信息，具体地，将声音传播速度分别与多个时间差输入至距离计算公式中，得到由多个时间差分别形成的距离信息；进一步地，由于用户目标位置信息是二维的，因此只有两个未知参数，通过两个方程式组成的方程组就可以计算出具体的参数信息，服务器可以获取两两声音接收装置的位置信息，将两个声音接收装置的位置信息结合由两个声音接收装置接收次声波时的时间差形成的距离信息，再根据点到点之间的距离公式形成一个方程式，在得到一个方程式后，服务器再获取上述两个声音接收装置其中一个声音接收装置，与其余声音接收装置中任一个声音接收装置接收次声波的时间差形成的距离信息，根据两个声音接收装置的位置信息与距离信息，形成第二个方程式，并由两个方程式构成方程组，以便于通过解方程组得到用户的目标位置信息。例如：可以先计算第一个声音接收装置与第二个声音接收装置接收次声波的时间差，由第一个声音接收装置的位置信息、第二个声音接收装置的位置信息、第一个声音接收装置与第二个声音接收装置的时间差计算得到的距离信息，结合点到点之间的距离计算公式生成第一个方程式；再计算第一个声音接收装置与第三个声音接收装置接收次声波的时间差，由第一个声音接收装置的位置信息、第三个声音接收装置的位置信息、第一个声音接收装置与第三个声音接收装置的时间差计算得到的距离信息，结合点到点之间的距离计算公式生成第二个方程式，最后由第一个方程式与第二个方程式组成方程组。Further, the server can obtain the sound propagation speed based on the wireless network, or can obtain the sound propagation speed from the internal memory; after obtaining the sound propagation speed, the server calculates the distance information formed by the time difference when each sound receiving device receives the infrasound wave according to the distance calculation formula and the sound propagation speed. Specifically, the sound propagation speed and multiple time differences are respectively input into the distance calculation formula to obtain the distance information formed by the multiple time differences; further, since the user's target position information is two-dimensional, there are only two unknown parameters, and the specific parameter information can be calculated by a system of equations composed of two equations. The server can obtain the position information of each pair of sound receiving devices, combine the position information of the two sound receiving devices with the distance information formed by the time difference when the two sound receiving devices receive the infrasound wave, and then form an equation according to the point-to-point distance formula. After obtaining an equation, the server then obtains the distance information formed by the time difference between one of the two sound receiving devices and any one of the remaining sound receiving devices receiving the infrasound wave, and forms a second equation according to the position information and distance information of the two sound receiving devices, and the two equations constitute an equation system, so that the user's target position information can be obtained by solving the equation system. For example, the time difference between the first sound receiving device and the second sound receiving device in receiving the infrasound wave can be calculated first, and the distance information calculated from the position information of the first sound receiving device, the position information of the second sound receiving device, and the time difference between the first sound receiving device and the second sound receiving device can be combined with the point-to-point distance calculation formula to generate the first equation; then the time difference between the first sound receiving device and the third sound receiving device in receiving the infrasound wave can be calculated, and the distance information calculated from the position information of the first sound receiving device, the position information of the third sound receiving device, and the time difference between the first sound receiving device and the third sound receiving device can be combined with the point-to-point distance calculation formula to generate the second equation; finally, the first equation and the second equation form a system of equations.
本实施例根据各声音接收装置的位置信息与时间差信息生成方程组，再对方程组进行求解，准确地计算出用户的目标位置信息，实现对用户进行精准定位。This embodiment generates a set of equations based on the position information and time difference information of each sound receiving device, and then solves the set of equations to accurately calculate the user's target position information, thereby achieving precise positioning of the user.
进一步地，参照图5，基于本发明声纹定位方法的第一实施例，提出本发明声纹定位方法的第四实施例，在第四实施例中，所述获取声音接收装置组接收用户基于预设二维码发送的次声波的时间差信息的步骤包括：Further, referring to FIG. 5 , based on the first embodiment of the voiceprint positioning method of the present invention, a fourth embodiment of the voiceprint positioning method of the present invention is proposed. In the fourth embodiment, the step of obtaining the time difference information of the infrasound waves sent by the user based on the preset QR code received by the sound receiving device group includes:
步骤S11，分别获取声音接收装置组中各声音接收装置接收用户基于预设二维码发送的次声波的时间信息；Step S11, respectively obtaining time information of each sound receiving device in the sound receiving device group receiving the infrasound wave sent by the user based on the preset QR code;
步骤S12，分别计算多个所述时间信息之间的时间差；Step S12, respectively calculating the time difference between the plurality of time information;
步骤S13，若时间差的数量大于或等于预设阈值，则将多个所述时间差生成为时间差信息。Step S13: if the number of time differences is greater than or equal to a preset threshold, then generating a plurality of the time differences as time difference information.
可以理解地，由于用户在通过预设终端发送次声波之前，需要向服务器发送次声波发送请求，因此服务器可以将向预设终端发送确认指令的时间确定为次声波的发送信息，或者获取与预设终端通信延时时长，通过延时时长对发送确认指令的时间进行补偿计算，得到次声波的发送信息。进一步地，服务器将次声波的发送时间分别与各声音接收装置接收次声波的接收时间进行差值运算，得到各声音接收装置从次声波发送到接收到次声波之间的时间信息。进一步地，服务器将多个时间信息分别进行两两差值运算，得到各声音接收装置接收次声波的多个时间差。由于确定二维的目标位置信息至少需要两个方程式才能进行求解，而要形成两个方程式又需要至少两个时间差来计算出两个距离信息，因此在检测到时间差的数量大于或等于预设阈值时，服务器才判定满足计算目标位置信息的条件，则将多个时间差生成为时间差信息，其中预设阈值为根据实际计算条件设定的数值，例如本申请中计算二维的位置信息，则预设阈值可以为2。It is understandable that, since the user needs to send an infrasound wave sending request to the server before sending the infrasound wave through the preset terminal, the server can determine the time of sending the confirmation instruction to the preset terminal as the sending information of the infrasound wave, or obtain the communication delay length with the preset terminal, and compensate the time of sending the confirmation instruction by the delay length to obtain the sending information of the infrasound wave. Further, the server performs a difference operation on the sending time of the infrasound wave and the receiving time of the infrasound wave by each sound receiving device, and obtains the time information from the sending of the infrasound wave to the receiving of the infrasound wave by each sound receiving device. Further, the server performs a difference operation on multiple time information respectively, and obtains multiple time differences for each sound receiving device to receive the infrasound wave. Since determining the two-dimensional target position information requires at least two equations to be solved, and forming the two equations requires at least two time differences to calculate the two distance information, the server determines that the conditions for calculating the target position information are met when it detects that the number of time differences is greater than or equal to the preset threshold, and then generates multiple time differences as time difference information, where the preset threshold is a value set according to the actual calculation conditions. For example, when calculating the two-dimensional position information in the present application, the preset threshold can be 2.
进一步地，所述分别计算多个所述时间信息之间的时间差的步骤之后，还包括：Furthermore, after the step of respectively calculating the time difference between the plurality of time information, the method further comprises:
步骤S14，将时间差的数量与预设阈值进行对比；Step S14, comparing the amount of time difference with a preset threshold;
步骤S15，若时间差的数量小于所述预设阈值，则判定所述声音接收装置组中存在声音接收装置发生故障，并输出故障提示信息。Step S15: If the number of time differences is less than the preset threshold, it is determined that a sound receiving device in the sound receiving device group is faulty, and fault prompt information is output.
进一步地，服务器识别计算出的时间差的数量，并将识别得到的时间差的数量与预设阈值进行对比，根据对比结果判断时间差的数量是否大于或等于预设阈值。进一步地，若经对比确定时间差的数量小于预设阈值，说明根据当前的时间差不能计算出用户的目标位置信息，进一步说明声音接收装置组的多个声音接收装置中至少存在一个声音接收装置发生故障，则生成故障提示信息，并将故障提示信息输出给管理人员，例如通过短信、小程序等方式发送给管理人员，以通知管理人员对声音接收装置组进行故障排查，保障声纹定位系统的正常运行，以实现对用户的精准定位。Further, the server identifies the number of calculated time differences, and compares the number of identified time differences with a preset threshold, and determines whether the number of time differences is greater than or equal to the preset threshold based on the comparison result. Further, if it is determined through comparison that the number of time differences is less than the preset threshold, it means that the user's target location information cannot be calculated based on the current time difference, and further indicates that at least one of the multiple sound receiving devices in the sound receiving device group has a fault, then a fault prompt information is generated, and the fault prompt information is output to the management personnel, for example, by sending it to the management personnel through SMS, mini-programs, etc., to notify the management personnel to troubleshoot the sound receiving device group, to ensure the normal operation of the voiceprint positioning system, and to achieve accurate positioning of the user.
本实施例通过获取声音接收装置组接收用户基于预设二维码发送的次声波的时间差信息，便于根据时间差信息计算出距离信息，再由距离信息结合声音接收装置组的位置信息计算出用户的目标位置信息，对用户进行精准定位。This embodiment obtains the time difference information of the infrasound waves sent by the user based on the preset QR code when the sound receiving device group receives them, so as to calculate the distance information according to the time difference information, and then calculate the user's target position information by combining the distance information with the position information of the sound receiving device group, so as to accurately locate the user.
进一步地，本发明还提供一种声纹定位装置。Furthermore, the present invention also provides a voiceprint positioning device.
