[0028] Such as figure 1 Shown is a flow chart of a mini-LED chip precise positioning method based on the YOLO algorithm, the method includes steps:
[0029] (1) Set the mark picture in the mini-LED chip to be tracked, set it at the predetermined pixel position in the image, and let the predetermined pixel position be the final position where the chip will stay; place the camera at the designated shooting position, start the conveyor belt and turn on the camera Capture images frame by frame in real time and send the images to the computer in real time;
[0030] The mark picture is used as a training sample. In the present invention, the target detection is to detect and match the mark picture, that is, to track the mark picture in real time. The mark picture is a small mark of the entire large chip and a fixed position mark of the chip. Unique in the entire image, by detecting this marker instead of detecting the entire chip.
[0031] The structure of the conveyor belt is as ...
