摘　　要：根据通用主动视觉系统的设计要求,提出了基于DSP的嵌入式主动视觉系统的设计方案,并完成系统的软硬件设计。最终实现的系统具有俯仰和摇摆2个自由度、支持双CCD视觉传感器和双倾角传感器。该系统的硬件分别采用TMS320C6711和TMS320F2812实现了视频处理、运动控制、传感器信息采集及系统与PC机之间的通讯。实验结果表明该系统具有计算和接口资源丰富、操作灵活等特点,达到设计要求。To satisfy the requirements of general active vision systems, the design of an embedded active vision system based on DSP and its implementation is proposed in this paper. The final system consists of two degree of freedoms in pan and tilt directions, double CCD video cameras, and two tilt sensors. The hardware system employs TMS320C6711 and TMS320F2812 to realize the functions of video processing, motion control, sensor feedback reading, and communication with PCs. The experiment results demonstrate that the system can meet the requirements with operational flexibility and rich computation and interface resources.
