中文摘要：
针对单线阵相机在大视场下传感器边缘的失光问题，设计了基于FPGA的拼接式线阵相机。采用将多个相机直线排列的方法，对视场进行分担，减小了单个相机的视场角。在检测微小颗粒掉落的应用中，在FPGA内部设计了目标位置的检测算法，并通过实验验证了系统的实用性和稳定性。实验结果表明，相机成像清晰，边缘失光较小，可准确区分目标和背景。
英文摘要：
Because single line-scan camera loses light in the edge of the sensor when the field of view is large, a mosaic cam- era based on field programmable gate array （FPGA） is presented by putting multiple cameras arranged in a straight line to share the field of view and reduce the view angle of every camera. For detecting doping micro particles with the designed mosaic line-scan camera, a detection algorithm of the target＇s location in FPGA is proposed. Finally, the practicability and stability of the system were validated experimentally. The results of the experiment show that the camera can get images clearly with less light loss and can accurately distinguish the target and the background.
