When the skylight 2 to be tested is acquired, the acquisition position of the camera 6 is kept constant. The pattern of the skylight 2 to be tested directly acquired by the camera 6 is defined as the second image. The single-chip microcomputer 13 calculates the image difference and parameter difference between the first image and the second image to quickly measure the light distortion parameters of the skylight 2 to be tested.

[0052] After a single light distortion parameter acquisition, the layout angle of the skylight 2 to be tested during the test can be changed, and then the light distortion parameters of the skylight 2 to be tested at different layout angles can be tested;

[0057] The supporting assembly is connected with a display screen 10 with adjustable angle and position. The detection frame 1 is also provided with a temperature difference control component for controlling the temperature difference between the inside and outside of the skylight 2 to be tested.

[0062] The skylight 2 to be tested is disposed between the second rotator 18 and the adjustment seat 12 .

[0063] The working principle of the present invention is as follows: in the present invention, when it is necessary to clean the surface of the skylight 2 to be tested before detection, firstly, under the driving action of the multi-axis mechanical arm, the nozzle 5 discharges liquid along the outer surface of the skylight 2 to be tested at a set angle, and sprays and cleans the skylight 2 to be tested. After the skylight 2 to be tested is sprayed and cleaned, under the driving action of the multi-axis mechanical arm, the brush plate 4 physically cleans the skylight 2 to be tested along the outer surface of the skylight 2 to be tested. By spraying and physically cleaning the skylight 2 to be tested, the surface cleanliness of the skylight 2 to be tested is maintained and the influence of residual dirt on the surface of the skylight 2 to be tested on the detection accuracy of the skylight 2 to be tested is reduced. When When the sunroof 2 to be tested is tested, the layout angle of the sunroof 2 to be tested can be limited by setting the adjusting arm push rod 27, and specifically, the angle of the sunroof 2 to be tested when laid out should simulate the actual layout angle and layout state of the sunroof 2 to be tested on the car. After the sunroof 2 to be tested is laid out with the set parameters, the display screen 10 displays the pattern, and the camera 6 collects the image on the display screen 10 through the sunroof 2 to be tested. The image collected by the camera 6 through the sunroof 2 to be tested is the first image, and when the first image is collected, the collection position of the camera 6 is recorded. After the first image is collected, the sunroof 2 to be tested is set to the setting of the adjusting arm push rod 27. The skylight 2 is in a flat state, and the flat state of the skylight 2 to be tested is maintained so that the camera 6 can directly capture the image of the skylight 2 to be tested. When the skylight 2 to be tested is captured, the capture position of the camera 6 remains constant, and the pattern of the direct image capture of the skylight 2 to be tested by the camera 6 is defined as the second image. The single-chip microcomputer 13 calculates the image difference and parameter difference between the first image and the second image to quickly measure the light distortion parameters of the skylight 2 to be tested. After a single light distortion parameter capture, the layout angle of the skylight 2 to be tested can be changed during the detection, and then the light distortion parameters of the skylight 2 to be tested at different layout angles can be detected. When the skylight 2 to be tested is in the layout state, the distance between the two deformation plates 24 can be controlled by setting the double-headed push rod 30, and then the skylight 2 to be tested is finally deformed within a safe range. The deformation of the skylight 2 to be tested is used to detect the influence of the deformation factor of the skylight 2 to be tested on the light distortion parameters of the skylight 2 to be tested. The angle of the display screen 10 can be adjusted to affect the distortion parameters of the skylight 2 to be tested. The temperature difference control component can be set to limit the internal and external temperature difference of the skylight 2 to be tested, and then the influence of the internal and external temperature difference factor of the skylight 2 to be tested on the light distortion parameters of the skylight 2 to be tested is detected.
