Embodiment Construction
[0033] The present invention will be further described below in conjunction with specific embodiments.
[0034] Such as figure 1 As shown, the basic units required for the implementation of the present invention include markers, image acquisition devices, image processing systems, and display devices, and each unit operates around the segment entity and the segment error control model.
[0035] The marker is a paper pattern printed in black and white, and the periphery of the paper pattern is surrounded by a black box. The role of the marker is to assist in image recognition. When in use, the marker is placed on the shield segment, and the best position is the adjacent segment contact.
[0036] The image acquisition device is composed of an ordinary USB camera, which is used to collect image information including image markers and segment entities, and transmit the collected information to the image processing system. During use, the shooting angle and distance of the USB ca...
