[0002] The automobile electronic rearview mirror is a new product in recent years, which is an indirect vision device for obtaining a specified field of view through a system composed of a camera and a monitor, and the monitor is installed in the driver's cabin. Different heights of people watch the monitor screen at different angles, and the brightness, contrast and other aspects will also be different. In the detection items of the automobile electronic rearview mirror, the detection of such differences is required. Although the existing technology has equipment capable of detecting screen brightness and contrast, there is no application technology for detecting the screen brightness and contrast reproduction of automobile electronic rearview mirrors for different height groups. SUMMARY

[0003] The purpose of the present application is to provide a method for detecting automobile electronic rearview mirror, which is particularly suitable for detecting screen brightness and contrast reproduction and other items.

[0004] The purpose of the present application is achieved by the following technical solution: a method for detecting automobile electronic rearview mirror, comprising the following steps:

[0005] 1) installing a laser emitter instrument with a flexible film pressure sensor attached to the bottom surface on the screen of the monitor of the automobile electronic rearview mirror, and monitoring the measurement value of the pressure sensor through a control system to ensure that the bottom surface of the laser emitter instrument is completely attached to the screen;

[0006] 2) installing a laser receiver instrument with a flexible film pressure sensor attached to the bottom surface on a detection device, and monitoring the measurement value of the pressure sensor through the control system to ensure that the bottom surface of the laser receiver instrument is completely attached to the detection device;

[0007] 3) adjusting the emission angle of the laser emitter instrument through the control system according to the viewing angle of the screen specified by the manufacturer of the automobile electronic rearview mirror;

[0008] 4) adjusting the position of the detection device until the laser receiver instrument on it receives the laser emitted by the laser emitter instrument, and then detecting the automobile electronic rearview mirror through the detection device at the position.

[0009] Advantages:

[0010] The manufacturer stipulates the angle of watching the screen of the automobile electronic rearview mirror monitor by people with different heights, and the laser emitter and the laser receiver are used to quickly and accurately position the detection equipment according to the stipulation, so that the automobile electronic rearview mirror can be conveniently detected in the laboratory, and the automobile electronic rearview mirror detection is suitable for different types of automobile electronic rearview mirrors.

[0015] The application will be further described in detail below in combination with the drawings and specific embodiments.

[0016] As shown in the drawings, Figure 1 the embodiment is a method for detecting the automobile electronic rearview mirror, which comprises the following steps:

[0017] Step 1) The laser emitter with a flexible film pressure sensor attached to the bottom is installed on the screen of the monitor of the automobile electronic rearview mirror, and the measurement value of the pressure sensor is monitored by the control system to ensure that the bottom of the laser emitter is completely attached to the screen, at this time, the laser emitted by the laser emitter is along the normal direction of the screen, as shown by the normal N in the drawing. Figure 4

[0018] The pressure sensor can upload data to the control system in a WiFi mode, the control system displays relevant data and a pressure cloud chart, and the user can judge whether the bottom of the laser emitter is completely attached to the screen according to the pressure cloud chart.

[0019] The preferred laser emitter is shown in the drawing. Figure 2

[0020] Step 2) The laser receiver with a flexible film pressure sensor attached to the bottom is installed on the detection equipment, and the measurement value of the pressure sensor is monitored by the control system to ensure that the bottom of the laser receiver is completely attached to the detection equipment, and the monitoring mode is the same as above.

[0021] The preferred laser receiver is shown in the drawing. Figure 2 ​​​

[0022] Step 3) Input the viewing angle of the screen specified by the automotive electronic rearview mirror manufacturer into the control system software. The control system adjusts the emission angle of the laser emitter according to the specified viewing angle. Figure 4 As shown in θ and Φ.

[0023] Step 4) Adjust the position of the detection device until the laser receiver on it receives the laser emitted by the laser transmitter, such as... Figure 4 Point P is shown in the diagram, and then the electronic rearview mirror of the car is inspected at that position using the detection device.

[0024] This invention, based on the viewing angle specifications of automotive electronic rearview mirror manufacturers, cleverly utilizes a laser emitter and laser receiver to achieve rapid and accurate positioning of the testing equipment, facilitating subsequent laboratory testing of automotive electronic rearview mirrors. This method is applicable to the testing of all types of automotive electronic rearview mirror products on the market and boasts advantages such as simple operation, laser alignment, minimal error, and intuitive visualization of the observation direction line via laser, demonstrating significant application value.
