【Abstract】 A video monitoring system must have the advantages of low cost and low power consumption. As to these requirements, ARM7-TDMI and CMOS image sensors are used as the core and peripheral circuits are coupled to realize the image capture function in our design. And through a USB2.0 interface, high-speed image data transmission is ensured. Finally, an SD card interface is adopted to store image data or an upper computer-based image display software is applied for the real-time display of image data. Experiments show that the embedded machine vision system can achieve real-time image capture functionality with lower cost and less power consumption so as to meet the needs of security monitoring systems.更多还原
