摘　　要：为了完成一个多传感器图像采集处理系统的设计、软硬件实现,采用参数同步配置方法提高多CMOS图像传感器同步曝光精度。采用基于Bayer颜色滤波阵列图像的残差集近无损压缩方法提高图像数据传输速度。系统三传感器曝光达到了微秒级同步精度,约为课题任务要求的1/29。在保证重建图像质量精度的前提下,数据传输速度提高了约4.4倍。给出了系统部分最终测试结果。To finish the system design, software and hardware implementation of a multiple-sensor image sampling and processing system, a parameter-configured method is applied to improve the synchronous precision of the multiple CMOS image sensors exposed synchronously, and a near lossless remainder set compression method for Bayer color filter array images is used to increase the data transmission rate. The parameter-configured method gets a synchronous precision in a time scale of microseconds, which is about 1/29 of the system design requirement. The remainder set compression method gets an about 4. 4 times faster data transmission rate than that of previous data transmission method, as is based on the quality of the reconstructed images. Part of the system test results are given finally.
