In order to meet the requirement of miniaturization in applications of binocular stereo vision and multiple-channel video imaging, a design method of dual-CMOS sensor image synchronization sensing system is proposed. The system acquires the images from two channels of CMOS synchronously, and then outputs images through a video interface. The system is designed based on CPLD, which realizes the transmission and storage of the two-channel video data by outputting in the odd frame and the even frame sequentially staggered manner. The application of the modular structure design in configuration of the CMOS sensors and data transmission, highly improves the stability and the flexibility of the system. Experiments verify good effect of display of the new system.
