摘　　要：为了实现更为自然的人机交互,利用机器视觉方法,设计了人体指示位置实时估计系统,建立了系统的几何模型。并利用DM642芯片在图像处理中的优异性能,开发了集图像采集、处理以及传输功能于一体的通用硬件平台。通过在实际工程中的应用和精度实验分析,证明了系统的有效性和实用性。This paper designed a pointing gesture visual estimation system in real-time in order to achieve more natural interaction method between man and computer. A geometry model is set in the basis of system configuration to accomplish this estimation. Toake advantage of DM642 performance in image processing, the system is implemented in the DM642 based on hardware plant integrated image capture, processing and transfer functions. This system has been applied in practical engineering. By analysis of experiment precision, the system is validated to be practical and effective.
