针对空间瞬变光辐射定位系统小体积,高性能,低功耗的要求,提出了一种以FPGA作为图像采集和处理核心的系统设计方案；该方案集成度高,可扩展性强,在单片FPGA上实现了对CMOS图像传感器的驱动,瞬变光辐射目标的分割,辨识及其重心的求取等；测试结果表明,在帧频为20fps时,该方案能够满足系统实时性要求,定位精度在0.15个像元以内,并且具有较好的稳定性.%Aiming at the requirements of spatial transient light locating system with small size, high performance and low power, a design scheme of image acquisition and processing based on FPGA is proposed. The scheme has the characteristics of high integration and high scalability. The CMOS control and driving timing and the location of spatial transient light are both implemented on one FPGA. In the case of 20 fps frame rate, experiment results show that the scheme can satisfy the requests of locating system and locate spatial transient light within 0. 15 pixel and with high stability.
