论述了以2K×2K面阵CMOS图像传感器LUPA4000为基础的2×2光学拼接系统视频电路的方案设计及具体软硬件设计。每块传感器具有独立焦平面电路和信号处理电路, 系统采用编码与控制电路实现4块传感器同时曝光成像和积分时间同步设置, 编码与控制电路将4块传感器的图像数据编码后通过一路Camera Link接口输出。实验成像结果表明, 电路运行可靠, 操作灵活, 可扩展性强, 能够得到很好的拼接图像。

In this paper, dissertated is the video circuit project design, hardware and software design of 2×2 optical stitching system based on 2K×2K area CMOS image sensor LUPA4000. Every sensor has its own focal plane and signal process circuit, and the system realizes four sensor exposal and integral time changing synchronously by coding and control circuit. The coding and control circuit arranges four sensor image data and sends out through one Camera Link interface. Experimental results show that the circuit runs stably, operates and expands flexibly and can get good stitching image.
