| 摘 要： | 基于Dalsa公司的面阵CCD评价板EKxxxx设计了一套高分辨率全帧CCD相机电路系统。系统采用专用集成芯片SAA8103和TDA9991构成时序发生器和驱动器，采用TDA9965进行前端信号处理。采用单片机对系统进行控制并应用Camera Link接口简化了体系结构。针对CCD多路输出时各通道存在不均匀性，提出采用两点校正法进行校正。该系统能以较高的帧频获取超高分辨率的图像，适用于航空拍摄、数字后背等场合。 |

| Abstract: | A design of a high resolution camera system based on DALSA's CCD evaluation kit EKxxxx was presented.It was composed of a pulse pattern generator(SAA8103),a vertical line driver(TDA9991),four analog-to-digital interfaces(TDA9965) and a system controller(P89LV51RD2).A camera link with medium configuration was adopted to transfer digital images.The software for controlling and debugging the camera was developed.To correct the non-uniformity of 4 outputs,a method based on two-point correction was described.The system can acquire ultra high resolution pictures at a high frame rate;thus it is suitable for aero photography. |
