[0024] It is worth noting that the image collector 2 uses a high-precision camera with extremely high shooting resolution and a high-precision focal length adjustment function, which can adaptively capture high-precision industrial parts images. The camera is also equipped with a data acquisition card with a high sampling rate and high resolution to ensure accurate data collection and transmission.

[0025] Reference Figure 3 and Figure 4 As shown, the working structure and process of the whole device are as follows: when the user has a measurement requirement, the control unit is remotely operated through the user interface on the display. The output instruction of the control unit will operate the pan-tilt support mechanism 1 to perform corresponding mechanical movement and camera control. The camera supported by the pan-tilt support mechanism 1 takes pictures after adjusting the appropriate position and adapting to the pan-tilt environment. The pictures are sent to the image processing unit for preliminary processing, and then the angle is measured in the image analysis unit.
