1、 The host functions must meet the following functional descriptions:
1) The image fusion host can overlay and display at least 10 rectangular areas with different sizes, positions, and transparency on input 1
2) It can communicate with the host through RS232 and add, delete, and modify the size, position, transparency, and other parameters of the rectangle overlay area in real-time during operation.
2、 The performance is as f
1) Delay: After layer overlay fusion, the delay of the image increases by<10s; after image overlay fusion, the delay of the overlay image increases by<20mss by<20ms
2) RS232 communication response time: Response time from sending command to executing<20ms
3) Maximum number of overlapping areas: 10
4) Screen difference: Collect two images with and without FPGA host, and the number of pixel color differences at the same position in the images is less than 0.01%
