近年来，由于各个方面的因素导致的眼科疾病和用眼不健康，导致越来越多的人患有近视、青光眼、眼底病变、白内障等各种疾病，大量的眼科检查已经成为常态。眼科检查需要区别左右眼，传统的方法是手动记录，容易产生记录错误，导致检验结果错误，影响诊断和治疗。目前个别检测设备已经开始探索进行左右眼的自动识别，采用视频、微波等方式。目前市面上出现的检测方式，主要采用视频、微波等方式。视频、微波方式需要进行复杂的算法计算和必要的空间结构，导致整体的成本居高不下。In recent years, due to eye diseases and unhealthy eye use caused by various factors, more and more people are suffering from myopia, glaucoma, fundus lesions, cataracts and other diseases. A large number of eye examinations have become the norm. Eye examination requires distinguishing between the left and right eyes.

Video and microwave methods require complex algorithm calculations and necessary spatial structures, resulting in high overall costs.

为了解决现有技术问题，本申请实施例提供了一种左右眼识别方法、装置、设备及介质。下面首先对本申请实施例所提供的左右眼识别方法进行介绍。In order to solve the existing technical problems, embodiments of the present application provide a left and right eye recognition method, device, equipment and medium. The following first introduces the left and right eye recognition method provided by the embodiment of the present application.

图1示出了本申请一个实施例提供的左右眼识别方法的流程示意图。如图1所示，该方法应用于眼压测量设备，眼压测量设备包括测量部、发射器和接收器，该方法具体可以包括如下步骤：Figure 1 shows a schematic flowchart of a left and right eye recognition method provided by an embodiment of the present application. As shown in Figure 1, this method is applied to intraocular pressure measurement equipment. The intraocular pressure measurement equipment includes a measurement part, a transmitter and a receiver. The method may specifically include the following steps:

S100，在测量部与眼睛相对的情况下，通过发射器以预设角度发射测试信号，测试信号包括第一光信号或第二光信号，第一光信号未携带编码，第二光信号携带编码，预设角度为朝向第一眼所在方位的角度，第一眼为左眼和右眼中的一者，第二眼为左眼和右眼中的另一者。S100, when the measurement part is opposite to the eye, transmit a test signal at a preset angle through the transmitter. The test signal includes a first optical signal or a second optical signal. The first optical signal does not carry a code, and the second optical signal carries a code. , the default angle is the angle toward the direction of the first eye, which is one of the left eye and the right eye, and the second eye is the other of the left eye and the right eye.

可选地，本申请实施例提供的左右眼识别方法应用于眼压测量装置，其中眼压测量装置的发射器用于发射测试信号，接收器用于接收环境光以及发射的测试信号等反射回的信号。测量部和接收器可以沿第一方向依次设置，发射器和接收器沿第二方向间隔设置，其中，第一方向和第二方向相交，第一方向可以是沿眼压测量装置的中轴线方向，第二方向与中轴线相垂直；亦或者是测量部、发射器、接收器沿第一方向依次设置。Optionally, the left and right eye identification method provided by the embodiment of the present application is applied to an intraocular pressure measurement device, in which the transmitter of the intraocular pressure measurement device is used to transmit test signals, and the receiver is used to receive signals reflected back from the ambient light and the transmitted test signals. . The measuring part and the receiver may be arranged sequentially along the first direction, and the transmitter and the receiver may be arranged at intervals along the second direction, where the first direction and the second direction intersect, and the first direction may be along the central axis of the intraocular pressure measuring device. , the second direction is perpendicular to the central axis; or the measuring part, transmitter, and receiver are arranged sequentially along the first direction.

可选地，在本申请实施例中，第一光信号可以是可见光线，例如波长范围在0.77～0.39微米之间的光线。在其他实施例中，第一光信号可以是红外光线，例如波长范围为0.76-1000微米的红外波段的电磁波。Optionally, in this embodiment of the present application, the first optical signal may be visible light, for example, light with a wavelength ranging from 0.77 to 0.39 microns. In other embodiments, the first optical signal may be infrared light, such as electromagnetic waves in the infrared band with a wavelength range of 0.76-1000 microns.

可选地，在本申请实施例中，第二光信号可以是具有编码的信号，例如光信号可以通过模拟信号或数字编码的方式携带数据，具体而言，可以是进行逻辑“1”和逻辑“0”的编码。容易理解的是，光信号也可以通过调制频率和相位来携带信息，本申请并不限于此。Optionally, in the embodiment of the present application, the second optical signal may be a signal with encoding. For example, the optical signal may carry data in the form of an analog signal or digital encoding. Specifically, it may be a logical "1" and a logical The encoding of "0". It is easy to understand that optical signals can also carry information by modulating frequency and phase, and the present application is not limited thereto.

可选地，在本申请实施例中，预设角度为朝向第一眼所在方位的角度是为了能够适应人脸面部的形状特征，使得测试信号可以在测量不同的眼睛时，拥有不同的反射效果。假设眼压测量装置在测量第一眼时，由于预设角度为朝向第一眼所在方位的角度，因此该测试信号会从人脸面部旁侧射出，例如从人脸耳畔射出，照射到人脸的后方；而眼压测量装置在测量第二眼时，由于预设角度为朝向第一眼所在方位的角度，因此该测试信号会大部分被人脸面部遮挡，由此能够使得测试产生不同的反射效果。需要理解的是，第一眼和第二眼为相对概念，因此预设角度可以根据第一眼和第二眼自行调整朝向方向，只要保证在测量不同的眼睛时，测试信号具有不同的反射效果即可。Optionally, in the embodiment of the present application, the preset angle is the angle toward the direction of the first eye in order to adapt to the shape characteristics of the human face, so that the test signal can have different reflection effects when measuring different eyes. . Assume that when the intraocular pressure measuring device measures the first eye, since the preset angle is towards the direction of the first eye, the test signal will be emitted from the side of the person's face, such as from the ear of the person's face, and illuminate the person's face. The back of the face; when the intraocular pressure measuring device measures the second eye, since the preset angle is towards the direction of the first eye, most of the test signal will be blocked by the human face, which can make the test different. reflection effect. It should be understood that the first eye and the second eye are relative concepts, so the preset angle can be adjusted according to the first eye and the second eye, as long as the test signal has different reflection effects when measuring different eyes. That’s it.

可选地，在本申请实施例中，预设角度的具体数值可以根据人脸脸型进行调整，例如眼压测量装置测量的是男性，则以男性预设角度射出，如果测量的是女性，则以女性预设角度射出。容易理解的是，本申请并不限制预设角度的确定方式，可以是通过模型训练得到的，亦或是在测量时通过人工调整的，只要能够实现在测量不同的眼睛时，测试信号具有不同的反射效果即可，本申请对此不做限定。Optionally, in the embodiment of the present application, the specific value of the preset angle can be adjusted according to the facial shape of the person. For example, if the intraocular pressure measuring device measures a male, it will shoot at the preset angle for a male. If it measures a female, then Ejaculates at a female preset angle. It is easy to understand that this application does not limit the method of determining the preset angle. It can be obtained through model training or manually adjusted during measurement, as long as it can be achieved that the test signal has different characteristics when measuring different eyes. The reflection effect is sufficient, and this application does not limit this.

可选地，眼压测量装置的测量部与眼睛相对，即眼压测量装置被放置于测量眼的正前方，且对齐居中于被测眼睛的角膜中心，此时则说明测试装置对准操作完成，可以进行下一步测量，此时开始进行左右眼的识别。Optionally, the measuring part of the intraocular pressure measuring device is opposite to the eye, that is, the intraocular pressure measuring device is placed directly in front of the measuring eye and aligned at the center of the cornea of the eye being measured. At this time, the alignment operation of the testing device is completed. , you can proceed to the next step of measurement, and start the identification of the left and right eyes at this time.

可选地，在本申请实施例中，可以根据测量需求和眼睛位置，确定朝向第一眼所在方位的角度。这个角度可以根据设备设计和用户需求进行预设。根据预设角度，使用发射器发射测试信号。具体而言，可以首先根据设备设计和测量需求进行设置，确定预设角度。随后，根据要求选择测试信号的类型。例如可以选择第一光信号或第二光信号进行测量。并根据预设角度调整发射器的发射角度，确保发射器以预设角度朝向第一眼所在的方位。随后在设定好的角度下，使用发射器发射选定的测试信号。发射器将产生相应的光信号，并照射到特定位置。Optionally, in this embodiment of the present application, the angle toward the direction of the first eye can be determined based on measurement requirements and eye position. This angle can be preset based on device design and user needs. Use the transmitter to transmit test signals according to the preset angle. Specifically, you can first make settings based on equipment design and measurement requirements to determine the preset angle. Subsequently, select the type of test signal according to the requirements. For example, the first optical signal or the second optical signal can be selected for measurement. And adjust the launch angle of the transmitter according to the preset angle to ensure that the transmitter faces the direction of the first sight at the preset angle. The transmitter is then used to transmit the selected test signal at the set angle. The emitter will generate a corresponding light signal and illuminate it at a specific location.

S200，通过接收器接收测试信号在照射到面部后和/或照射到环境后反射回的反射信号。S200: Receive, through the receiver, the reflected signal reflected back by the test signal after it is irradiated on the face and/or after it is irradiated on the environment.

可选地，在本申请实施例中，反射信号即为测试信号在照射到人脸面部后或者是在照射到环境中反射回来的反射信号。需要说明的是，由于测试信号是以预设角度发射的测试信号，因此，测试信号在测量不同的眼睛时，接收到的反射信号的信号强度是存在差异的。Optionally, in this embodiment of the present application, the reflection signal is a reflection signal that is reflected back after the test signal is irradiated onto the human face or after being irradiated into the environment. It should be noted that since the test signal is a test signal transmitted at a preset angle, when the test signal is measured on different eyes, the signal strength of the received reflected signal is different.

可选地，在本申请实施例中，可以通过上述眼压测量装置的接收器接收反射信号，其中，在本申请一种可能的实现方式中，可以根据测试信号自身的标识信息确定，接收到的反射信号是属于测试信号的反射信号。具体而言，标识信息可以是专属于测试信号的编码符号，通过读取该编码符号可以识别出接收到的反射信号是否属于测试信号反射回的信号。Optionally, in the embodiment of the present application, the reflected signal can be received through the receiver of the above-mentioned intraocular pressure measurement device. In a possible implementation of the present application, the received signal can be determined based on the identification information of the test signal itself. The reflected signal is the reflected signal belonging to the test signal. Specifically, the identification information may be a coded symbol unique to the test signal. By reading the coded symbol, it can be identified whether the received reflected signal belongs to the signal reflected back by the test signal.

可选地，在本申请另一种可能的实现方式中，还可以根据测试信号的发射频率来识别接收到的反射信号是否属于测试信号反射回的信号。在本申请实施例中，眼压测量装置的接收器在接收到反射信号时，可能同时会接收到环境光，这一部分环境光通常是直流信号，可以直接通过滤波的方式过滤掉，具体而言，可以使用高通滤波器或者低通滤波器进行电子过滤，以过滤掉直流信号。但是在实际测量环境中还会存在一些调制光，这一部分光无法通过上述直流信号滤波的方式过滤掉，这一部分调制光往往具有与测试信号不同的频率，因此，可以通过设置一个光学滤波器，通过光学滤波器对调制光进行过滤，光学滤波器可以通过按频率选择性地通过或阻挡特定频率的信号来实现信号的过滤。例如，可以使用带通滤波器通过期望频率的光(即第测试信号的频率)，并使用阻挡滤波器阻挡频率不同的光(即调制光)。更具体地，还可以使用干涉滤波器、棱镜滤波器或折射滤波器实现光信号过滤。Optionally, in another possible implementation of the present application, whether the received reflected signal belongs to the signal reflected back by the test signal can also be identified based on the transmission frequency of the test signal. In the embodiment of the present application, when the receiver of the intraocular pressure measurement device receives the reflected signal, it may also receive ambient light. This part of the ambient light is usually a DC signal and can be directly filtered out through filtering. Specifically, , you can use a high-pass filter or a low-pass filter for electronic filtering to filter out the DC signal. However, in the actual measurement environment, there will still be some modulated light. This part of the light cannot be filtered out by the above-mentioned DC signal filtering method. This part of the modulated light often has a different frequency from the test signal. Therefore, an optical filter can be set. The modulated light is filtered through an optical filter, which can achieve signal filtering by frequency-selectively passing or blocking signals of specific frequencies. For example, a bandpass filter can be used to pass light of a desired frequency (i.e., the frequency of the test signal), and a blocking filter can be used to block light of a different frequency (i.e., modulated light). More specifically, optical signal filtering can also be achieved using interference filters, prism filters or refractive filters.

可选地，在本申请实施例中，可以首先根据测量需求和设备规格，设置接收器的参数，包括增益、灵敏度等，确保接收器能够接收到从面部反射回来的反射信号，并能够测量到反射信号的信号强度。其中，增益、灵敏度等参数的设置将影响接收器对反射信号的接收和解析能力。随后可以将接收到的反射信号进行信号采集和处理，并将其转换为电信号，这包括对信号进行放大、滤波、去噪等处理，以提取有用的信息并减少干扰。随后可以通过测量反射信号的强度、频率、相位等参数以提取有关反射信号的信息，分析测试信号的反射情况，并以此来识别当前测量的眼睛为左眼还是右眼。Optionally, in the embodiment of this application, you can first set the parameters of the receiver according to the measurement requirements and equipment specifications, including gain, sensitivity, etc., to ensure that the receiver can receive the reflected signal reflected from the face and be able to measure The signal strength of the reflected signal. Among them, the settings of parameters such as gain and sensitivity will affect the receiver's ability to receive and analyze reflected signals. The received reflected signal can then be collected and processed, and converted into an electrical signal. This includes amplifying, filtering, denoising and other processing of the signal to extract useful information and reduce interference. You can then extract information about the reflected signal by measuring the intensity, frequency, phase and other parameters of the reflected signal, analyze the reflection of the test signal, and use this to identify whether the eye currently being measured is the left eye or the right eye.

S300，根据反射信号的信号强度或编码，确定当前测量的眼睛为左眼或右眼。S300: Determine whether the currently measured eye is the left eye or the right eye based on the signal strength or coding of the reflected signal.

可选地，在本申请一种可能的实现方式中，假设测试信号为第一光信号的情况下，可以通过比较反射信号的信号强度的大小来判别当前正在测量的眼睛为左眼还是右眼。在本申请另一种可能的实现方式中，假设测试信号为第二光信号的情况下，可以通过读取分析反射信号中携带的具体编码值，从而识别出当前正在测量的眼睛为左眼还是右眼。Optionally, in a possible implementation of the present application, assuming that the test signal is the first light signal, it can be determined whether the eye currently being measured is the left eye or the right eye by comparing the signal intensity of the reflected signal. . In another possible implementation of the present application, assuming that the test signal is the second light signal, the specific code value carried in the reflected signal can be read and analyzed to identify whether the eye currently being measured is the left eye or the left eye. Right eye.

可选地，在本申请实施例中，利用发光器，发射固定角度的光线，光线可能被面部遮挡，或者光线从人脸面部旁侧发射到环境中，然后接收器感知到反射光线的强度变化，由此来判断当前眼压测量装置对应的位置是左眼还是右眼。因此可以根据接收到的反射信号的信号强度，比较左眼和右眼的反射信号强度差异。如果测试信号中包含了编码信息，可以通过解码分析来确定眼睛的测量。根据编码的特征，比如特定的频率、时序、模式或编码值，将接收到的反射信号与左眼和右眼的编码进行比较，以确定当前测量的眼睛。Optionally, in the embodiment of the present application, a light emitter is used to emit light at a fixed angle. The light may be blocked by the face, or the light may be emitted from the side of the human face into the environment, and then the receiver perceives the intensity change of the reflected light. , thereby determining whether the position corresponding to the current intraocular pressure measurement device is the left eye or the right eye. Therefore, the difference in reflected signal intensity between the left eye and the right eye can be compared based on the signal intensity of the received reflected signal. If the test signal contains coded information, decoding analysis can be used to determine eye measurements. Based on the characteristics of the encoding, such as a specific frequency, timing, pattern, or encoding value, the received reflected signal is compared to the encoding of the left and right eyes to determine which eye is currently being measured.

可选地，在本申请一种可能的实现方式中，可以首先建立一个参考标准，用于确定左眼和右眼的信号强度或编码范围。这可以通过预先进行校准或者基于经验设定的阈值来实现。随后将接收到的反射信号的信号强度或编码与参考标准进行比较。如果信号强度或编码落在左眼的参考范围内，则可以确定当前测量的眼睛为左眼；如果信号强度或编码落在右眼的参考范围内，则可以确定当前测量的眼睛为右眼。Optionally, in a possible implementation of the present application, a reference standard may be first established to determine the signal strength or coding range of the left eye and the right eye.

Compare the difference with the threshold: compare the absolute value of the obtained difference with the third preset threshold. If the absolute value of the difference is greater than the third preset threshold, the currently measured eye may be determined to be the second eye.

可选地，在本申请一种可能的实现方式中，以第一眼为右眼，第二眼为左眼为例进行说明，由于测试信号朝向右眼发射，因此在测试左眼时，测试信号的大部分光线照射在人体右侧面部和鼻骨附近，在面部的遮挡下形成漫反射，此时接收器3能够接收到较多的反射信号，因此此时测试环境光与初始环境光相比，势必包括更多的反射信号，即说明此时初始环境光强度和测试环境光强度的差值的绝对值大于第三预设阈值，可以判断当前测量的眼睛为左眼。Optionally, in a possible implementation of this application, the first eye is the right eye and the second eye is the left eye.
