本申请实施例涉及电子设备技术领域，尤其涉及一种指纹采集方法、装置、存储介质及电子设备。The embodiments of the present application relate to the technical field of electronic devices, and in particular, to a fingerprint collection method, device, storage medium, and electronic device.
背景技术Background technique
随着电子设备的快速发展，指纹采集和识别成为电子设备的常用功能，诸如手机和平板电脑等电子设备均具有指纹采集和识别的功能。With the rapid development of electronic devices, fingerprint collection and identification have become common functions of electronic devices, and electronic devices such as mobile phones and tablet computers have the function of fingerprint collection and identification.
目前的电子设备中一般是将指纹采集传感器设置在物理按键下方，例如物理按键可以是home键，以便用户通过按压home键准确输入指纹的位置。但是当电子设备中不设置home键，或者电子设备的屏幕为全面屏时，用户无法确定输入指纹的位置。当指纹采集失败时，由于导致指纹采集失败的原因有多种，用户无法确定指纹采集失败的原因，需要用户通过多次尝试，以排除指纹采集失败的原因，操作繁琐，效率低。In current electronic devices, the fingerprint acquisition sensor is generally arranged below the physical key, for example, the physical key may be the home key, so that the user can accurately input the position of the fingerprint by pressing the home key. However, when the home button is not set in the electronic device, or the screen of the electronic device is a full screen, the user cannot determine the position where the fingerprint is input. When the fingerprint collection fails, there are many reasons for the failure of the fingerprint collection, and the user cannot determine the reason for the failure of the fingerprint collection, and the user needs to make multiple attempts to eliminate the cause of the failure of the fingerprint collection, which is cumbersome and inefficient.

In this embodiment, each time an operation of inputting a fingerprint is detected, the touch position of the input fingerprint and the degree of clarity of the fingerprint are determined synchronously, and the obtained touch position of the input fingerprint and the degree of clarity of the fingerprint are judged at the same time, and when both meet the preset requirements When the fingerprint collection conditions are met, it is determined that the fingerprint collection is successful. When one or both of the touch position of the input fingerprint and the fingerprint clarity do not meet the preset fingerprint collection conditions, it is determined that the fingerprint collection fails. Exemplarily, when a fingerprint input operation is detected, the fingerprint sensor is activated to obtain fingerprint information, and whether the touch position of the input fingerprint meets the preset fingerprint collection conditions is determined according to the area of the obtained fingerprint information. When the area of the information is smaller than the preset value, it is determined that the touch position of the input fingerprint does not meet the preset fingerprint collection conditions; when the area of the acquired fingerprint information is greater than or equal to the preset value, it is determined that the touch position of the input fingerprint meets the preset fingerprint collection conditions , and further, determine the clarity of the collected fingerprint information.

When it is determined that the fingerprint collection fails according to the state parameter, the reason for the failure of fingerprint collection is determined according to the state parameter of the input fingerprint, wherein the reason for the failure of fingerprint collection may be, but not limited to, the deviation of the fingerprint input position or the dirty finger of the user. Based on the determined cause of fingerprint collection failure, prompt information is generated to prompt the user for a correct fingerprint input method. Exemplarily, the prompt information may be output in a text form, a graphic form or a voice form. Specifically, the text "finger is dirty" may be displayed on the screen, or the position of the fingerprint sensor may be prompted by a preset mark (a circular mark, an oval mark or a rectangular mark, etc.). For example, see FIG. 2a and FIG. 2b. FIG. 2a and FIG. 2b are schematic diagrams of displaying prompt information by an electronic device provided by an embodiment of the present application.

在本实施例中，在输入指纹的触摸位置准确的基础上，启动指纹传感器，获取指纹信息，并判断指纹的清晰程度，避免在指纹输入位置偏差时启动指纹传感器导致的功耗。其中，指纹传感器包括超声波指纹传感器、光学指纹传感器、电容式指纹传感器。示例性的，当指纹传感器为光学指纹传感器时，所述基于所述指纹传感器采集用户的指纹信息，包括：基于所述光学指纹传感器中的光信号发射器向棱镜(例如可以是三棱镜)发射光信号，其中，所述棱镜射出的光信号在传输至手指表面时发生反射；由于手指表面有凹凸不平的线纹，当光线照射到手指表面时，反射的光信号的明暗程度不同，基于所述光学指纹传感器中的摄像头采集所述手指表面反射的光信号，形成不同明暗程度的图像信息，即用户的指纹信息。In this embodiment, on the basis that the touch position of the input fingerprint is accurate, the fingerprint sensor is activated, the fingerprint information is obtained, and the clarity of the fingerprint is judged to avoid power consumption caused by activation of the fingerprint sensor when the input position of the fingerprint is deviated. The fingerprint sensor includes an ultrasonic fingerprint sensor, an optical fingerprint sensor, and a capacitive fingerprint sensor. Exemplarily, when the fingerprint sensor is an optical fingerprint sensor, the collecting the user's fingerprint information based on the fingerprint sensor includes: emitting light to a prism (for example, a triangular prism) based on the optical signal transmitter in the optical fingerprint sensor signal, wherein the light signal emitted by the prism is reflected when transmitted to the surface of the finger; due to the uneven lines on the surface of the finger, when the light hits the surface of the finger, the reflected light signal has different degrees of brightness and darkness. The camera in the optical fingerprint sensor collects the light signal reflected from the surface of the finger to form image information with different degrees of brightness, that is, the user's fingerprint information.
在一些实施例中，指纹传感器还可以是超声波指纹传感器，基于超声波指纹传感器向用户手指发送超声波信号，其中由于用于手指有凹凸不平的线纹，反射信号的接收时刻不同，根据反射信号的接收时刻，确定用户手指表面与超声波传感器的距离，并根据距离生成不同明暗的指纹信息，其中，可以是距离越小颜色越暗。在一些实施例中，还可以是基于电容式指纹传感器采集指纹信息，当用户手指触摸屏幕时，确定每一个像素点的电容值，其中，像素点与手指表面的距离越大，像素点的电容值越小，像素点与手指表面的距离越小，像素点的电容值越大。指纹具有指纹谷和指纹峰，用户手指触摸屏幕时，指纹峰与像素点的距离小，指纹谷与像素点的距离大，即指纹峰对应的像素点的电容值较大，指纹谷对应的像素点的电容值较小，形成指纹信息。In some embodiments, the fingerprint sensor may also be an ultrasonic fingerprint sensor, which sends ultrasonic signals to the user's finger based on the ultrasonic fingerprint sensor, wherein due to the uneven lines on the finger, the receiving time of the reflected signal is different, according to the receiving time of the reflected signal. At the moment, the distance between the surface of the user's finger and the ultrasonic sensor is determined, and fingerprint information of different brightness and darkness is generated according to the distance, wherein the smaller the distance, the darker the color. In some embodiments, fingerprint information can also be collected based on a capacitive fingerprint sensor. When the user's finger touches the screen, the capacitance value of each pixel is determined. The greater the distance between the pixel and the finger surface, the greater the capacitance of the pixel. The smaller the value, the smaller the distance between the pixel and the surface of the finger, and the larger the capacitance value of the pixel. Fingerprints have fingerprint valleys and fingerprint peaks. When the user's finger touches the screen, the distance between the fingerprint peak and the pixel is small, and the distance between the fingerprint valley and the pixel is large, that is, the capacitance value of the pixel corresponding to the fingerprint peak is larger, and the pixel corresponding to the fingerprint valley is larger. The capacitance value of the dot is small, forming the fingerprint information.
在一些实施例中，在采集指纹信息后，确定采集的指纹信息的清晰程度，包括：识别所述指纹信息中有效指纹面积；根据所述有效指纹面积和预设清晰程度规则确定所述指纹信息的清晰程度。其中，有效指纹为能清晰识别指纹特征的指纹，例如可识别指纹信息中指纹峰、指纹谷以及指纹信息中的中断、分叉或打折等局部特征。预设清晰程度规则中包括指纹清晰程度与有效指纹面积范围的对应关系，根据指纹信息的有效指纹面积确定其相匹配的指纹清晰程度。示例性的，指纹清晰程度可以是划分为两个等级，第一清晰程度和第二清晰程度，其中，第一清晰程度对应的有效指纹面积范围可以是大于或等于标准指纹面积的80％，第二清晰程度对应的有效指纹面积范围可以是小于标准指纹面积的80％，当指纹传感器采集的指纹信息为第一清晰程度时，即满足预设清晰程度，确定指纹采集成功，当指纹传感器采集的指纹信息为第二清晰程度时，即不满足预设清晰程度，确定指纹采集失败。需要说明的是，指纹清晰程度并不仅限于两个等级，在其他实施例中，还可以是根据用户需求设置两个以上的等级。In some embodiments, after collecting fingerprint information, determining the degree of clarity of the collected fingerprint information includes: identifying an effective fingerprint area in the fingerprint information; determining the fingerprint information according to the effective fingerprint area and a preset degree of clarity rule clarity. An effective fingerprint is a fingerprint that can clearly identify fingerprint features, such as fingerprint peaks, fingerprint valleys in fingerprint information, and local features such as interruptions, bifurcations, or discounts in fingerprint information. The preset sharpness rule includes the correspondence between the fingerprint sharpness and the effective fingerprint area, and the matching fingerprint sharpness is determined according to the effective fingerprint area of the fingerprint information. Exemplarily, the degree of fingerprint clarity may be divided into two levels, a first degree of clarity and a second degree of clarity, wherein the range of the effective fingerprint area corresponding to the first degree of clarity may be greater than or equal to 80% of the standard fingerprint area, and the The effective fingerprint area corresponding to the second degree of clarity can be less than 80% of the standard fingerprint area. When the fingerprint information collected by the fingerprint sensor is at the first degree of clarity, the preset degree of clarity is satisfied, and the fingerprint collection is determined to be successful. When the fingerprint information is at the second level of clarity, that is, it does not meet the preset level of clarity, it is determined that the fingerprint collection fails. It should be noted that the degree of fingerprint clarity is not limited to two levels, and in other embodiments, more than two levels may also be set according to user requirements.
当所述指纹清晰程度不满足预设清晰程度时，确定指纹采集失败原因为用户手指脏污，生成提示信息，以提示用户清除手指脏污或切换其他手指，避免用户无效的指纹输入操作。需要说明的是，在检测到电子设备进入指纹采集模式时，确定屏幕的指纹采集范围是否存在污渍，若是，则生成提示信息，以提示用户清除屏幕表面的污渍，避免该污渍影响指纹采集，以及混淆指纹采集失败原因的情况。When the fingerprint clarity does not meet the preset clarity, it is determined that the fingerprint collection failure is caused by the user's finger being dirty, and prompt information is generated to prompt the user to remove the dirty finger or switch other fingers to avoid invalid fingerprint input operations by the user. It should be noted that when it is detected that the electronic device enters the fingerprint collection mode, it is determined whether there is any stain in the fingerprint collection range of the screen, and if so, a prompt message is generated to prompt the user to remove the stain on the screen surface, so as to prevent the stain from affecting the fingerprint collection, and Confuses the reason for the failure of fingerprint collection.
在一些实施例中，当在预设时间内(例如可以是30s)连续两次或两次以上的指纹采集失败的原因均为手指脏污时，生成用于提示用户转换指纹输入角度的提示信息。其中，根据采集的指纹信息识别手指脏污位置以及脏污面积，当脏污面积大于第一面积时，提示用户采用其他手指输入指纹或者采用其他生物特征信息替代指纹信息，当脏污面积小于第一面积时，确定未脏污区域以及手指转换角度，根据手指转换角度生成提示信息，通过文字形式显示在屏幕或者通过扬声器进行语音播放。示例性的，当手指脏污位置为手指左侧，生成的提示信息可以是“请将手指向右旋转45度”，采集指纹右侧以及边缘的指纹信息。示例性的，手指脏污位置为手指中心，可以是分多次提示用户转换角度以采集手指边缘指纹信息，将多次采集的指纹信息进行拼接，当拼接的指纹信息中的有效指纹面积达到第二面积时，确定指纹采集成功，并基于拼接形成的指纹信息进行指纹识别。通过确定手指脏污位置以及脏污面积，确定该手指是否能够输入指纹的要求，避免手指脏污面积过大时，用户的无效操作。进一步的通过提示用户转换指纹输入角度，便于用户快速输入有效指纹，提高指纹输入效率以及电子设备的智能化。In some embodiments, when two or more consecutive fingerprint acquisition failures within a preset time (for example, 30s) are caused by dirty fingers, prompt information for prompting the user to switch the fingerprint input angle is generated . Among them, the dirty position and dirty area of the finger are identified according to the collected fingerprint information. When the dirty area is larger than the first area, the user is prompted to use other fingers to input the fingerprint or use other biometric information to replace the fingerprint information. When the dirty area is smaller than the first area When the area is one area, determine the uncontaminated area and the switching angle of the finger, generate prompt information according to the switching angle of the finger, and display it on the screen in the form of text or play it through the speaker. Exemplarily, when the dirty position of the finger is on the left side of the finger, the generated prompt information may be "Please rotate the finger by 45 degrees to the right", and the fingerprint information on the right side and the edge of the fingerprint is collected. Exemplarily, the dirty position of the finger is the center of the finger, and the user can be prompted to change the angle in multiple times to collect fingerprint information on the edge of the finger, and the fingerprint information collected multiple times is spliced. When there are two areas, it is determined that the fingerprint collection is successful, and fingerprint identification is performed based on the fingerprint information formed by splicing. By determining the dirty position and dirty area of the finger, it is determined whether the finger can input the requirements of the fingerprint, so as to avoid the invalid operation of the user when the dirty area of the finger is too large. Further, by prompting the user to switch the fingerprint input angle, it is convenient for the user to quickly input an effective fingerprint, and the efficiency of fingerprint input and the intelligence of the electronic device are improved.
