基于DM642芯片的嵌入式双目机器视觉平台

Embedded Horopter Machine Vision Platform Based on DM642

介绍了基于DM642平台的嵌入式双目立体视觉平台的硬件构成和驱动程序结构的设计和实现。该系统充分利用DM642芯片在图像处理中的优异性能,克服了传统基于采集卡和PC机的图像处理系统的实时性差,处理精度低,保密性差和扩展性差等缺点,其主要的图像处理工作由DSP实现,并可通过多种途径与PC机交互,大大降低了计算机的负荷。该平台采用面向对象的软件设计思路设计硬件,达到硬件重用的目的。

This paper introduces the structure and key technology of embedded horoper stereo vision platform based on DM642 and video driver chip implementation, This system takes full advantage of the excellent performance in image processing chip- DM642. It gets over the shortcomings such as the poor real-time image processing system to handle low precision, low confiden- tiality and poor scalability of the traditional PC-based data acquisition card. The DSP takes the main responsibility of image processing work and can communicate with PC via various channels and thus reduce the burden on the computer. The hardware of the platform is designed by using the design idea of object-oriented software for hardware reuse.
