Optionally, the second movement mechanism 42 is a six-axis robot.

[0056] It should be noted that the eyebox position refers to the active area of the eyes when the driver in the car can see the complete display image, which is a three-dimensional area.

Only when the eyes of the driver are in the eyebox, it can be ensured that the virtual display content is clear and complete. The size and position of the eyebox will directly affect the display effect and user experience of the HUD. Therefore, moving the camera 41 to the eyebox position for detection can make the detection result more accurate.

[0057] In addition, the detection mechanism 40 of the embodiment of the application can use a binocular imaging colorimeter. The binocular imaging colorimeter enables the instrument to simulate the visual perception process of the human eye to some extent. The two channels of the binocular imaging colorimeter can more truly reflect the color effect seen by the human eye. In addition, the binocular imaging colorimeter can be integrated with the second movement mechanism 42 for use, or can be detached for separate use.

[0058] In actual operation, first, the glass is placed on the support frame 10, and the glass is completely attached by adjusting the support column 12 and the limiting block. Then, the driver 221 drives the pusher 21 to move, and the two pushers 21 clamp and push the glass to move, so as to center the glass.

Finally, the lower viewing angle, the left viewing angle, the ghosting, the distortion and the like of the image are analyzed through an algorithm.

[0059] In addition, the detection device of the embodiment of the application also needs to be position calibrated when in use. First, the origin detection is performed to determine the origin coordinates (the lower left corner of the support frame 11) with three coordinate reference holes. Then, the limiting piece 13 position detection calibration, the support column 12 position detection calibration, the second movement mechanism 42 origin detection calibration, the camera 41 position detection calibration, the first movement mechanism 32 origin detection calibration and the projection source 31 position detection calibration are performed in sequence.
