Design and implement a high-resolution iris image acquisition hardware system using 10-megapixel high-resolution CMOS digital camera MT9J003 and USB3.0 bus interface. Through the Cyclone III series high-performance FPGA, the collected high-resolution iris image is displayed on the liquid crystal in real time, and different calibration methods are analyzed and studied. Internal and external parameters of the camera. A music teaching form composed of a music-assisted teaching system and music production software. It integrates viewing, listening, and practicing, changing the traditional one-to-one teaching mode. Its core composition adopts professional audio processing chip and processor to realize controllable digital audio communication channel, which solves the problem of interference well.
