The image acquisition and processing system is an important part of the laser imaging radar system. The article briefly introduces the design, composition, working process and software flow of an image acquisition and processing system with a master/slave computer structure. Use the interrupt function of the master/slave computer to realize the frame real-time acquisition, processing and display of image data. A dedicated DMA controller is designed using CPLD and shares two identical dual-port memories with the slave computer ADSP21020, and continuous image buffering and acquisition processing are completed by synchronously switching memory control. The test results show that the system can well complete the frame real-time acquisition, processing and display of laser imaging radar.
