摘　　要：基于PC实现的视线跟踪系统普遍存在执行速度慢、不能满足实时应用需求等缺陷,本研究以TI公司的TMS320DM642图像处理芯片作为数字图像处理硬件平台,以DSP/BIOS为实时操作系统,利用CCS开发环境构建应用程序,对程序整体结构框架进行了改进,对核心模块和代码逐个进行优化,以实现和优化基于DM642嵌入式系统的视线跟踪技术.Implementation of the eye gaze tracking system based on PC widely has some disadvantages, such as it＇s excution speed is slow and it could not satisfy the demand for real-time applications. The TMS320DM642 image pro cessing chip produced by TI Corporation is used as digital image processing hardware platform, the DSP/BIOS is used as real-time operating system, and the CCS is used to develop application program of environment structure, the overall structure of the program framework is improved and the core modules and codes are optimized in order to achieve and optimize the eye gaze tracking technology based on the DM642 embedded system.
