Embodiment approach
[0044] An embodiment of the present invention is: the control circuit board completes the configuration of the infrared camera, the infrared camera only collects a few lines of image data in the infrared light reflection area, and transmits the image data to the main controller for processing in the form of USB data .
[0045] A camera type multi-target positioning method based on image correction, characterized in that it comprises the following steps:
[0046] 1) Four infrared cameras installed at the top corners of the screen collect image information on the screen surface, and the control circuit board transmits the collected image data to the main controller through USB;
[0047] 2) For an infrared camera, its imaging area greater than 90 degrees, because there is no reflective strip to reflect infrared light, the imaging is a shadow area, and one end of it is taken as the imaging start end, starting from P 1 position to start imaging, according to P 1 The distance d to...
