Comparison Of Advantages And Disadvantages Of Camera Debugging Methods

1. CRT adjustment method. By connecting to the camera video signal, the CRT can display machine vision with high fidelity. But it can only be limited to the camera parameter test and the camera mechanical position adjustment, and can do nothing for the digital signal of the advanced point.

2. LCD debugging method. It is directly connected to the SPI port of the single-chip microcomputer for data transmission, and can refresh and display pictures in real time. This module can be directly mounted on the system to display system-related information in real time. However, due to the limitation of module resolution, only black and white binary values can be displayed, resulting in distortion of digital pictures.

3. Serial debugging method. It can make full use of the powerful data processing and picture display functions of the PC, realize the high-precision pixel display of digital pictures, and export the gray value table to provide on-site data for VC and MATLAB simulation. But the data transmission speed between PC and MCU is too slow, lacks real-time performance, and lacks the advantages of dynamic tracking.
