Design of Micro High-performance Information Acquisition System Based on CMOS

Aiming at the problem that the internal motion process of the fuze cannot be obtained when it is in high-speed motion, a design scheme of a miniature high-speed imaging and information processing system based on COMS is proposed. In the hardware design, the OV7725 CMOS high-speed image sensor is used as the front end of the image acquisition system. In the control and module processing, STM32F103RET6 is used as the main chip, the external cache chip AL422B writes the output information into the data buffer, and the OV7725 storage unit is used as the storage unit of the software part. At the same time, the design of power supply, interface circuit and reset module is introduced. In the software design, the Altium Designer system is used as the embedded development environment, and the software system hierarchy and image software processing flow are introduced. The experimental results show that the system is small in size, high in frame rate, stable in operation, and captures clear and smooth images.
