摘　　要：Qt/embedded是图形化界面开发工具的嵌入式版本,整体采用面向对象编程,拥有较高的运行效率和良好的体系架构和编程模式。达芬奇技术是基于DSP的数字音视频优化的系统解决方案,它在嵌入式操作系统方面对Linux的支持极为完善,可以实现复杂GUI系统的设计。利用qt/embedded和达芬奇技术完成了人脸识别器的图形用户界面设计,实现了人脸检测结果显示,人脸数据的修改和更新功能。另外成功实现了qt/em-bedded在DM6446上的移植,并有效使用了DM6446的视频处理前端和视频处理后端实现视频采集和显示。Qt/embedded is a graphical interface development tools embedded version.It is the whole object-oriented programming and has high run efficiency and good architecture and programming model.Davinci technology is a system solution for digital audio and video optimization based on Digital Signal Processing（DSP）.It supports Linux in the embedded operating systems perfectly and it can realize complex design of graphical user interface system.It uses qt/embedded and Davinci technology to complete the graphical user interface design of the face recognition devices and realizes the display of the face detection results,the modification and update of the face data.In addition it realizes qt/embedded transplant on the DM6446 successfully and it uses the Video Processing Front End（VPFE） and Video Processing Back End（VPBE）of the DM6446 to realize the video acquisition and display effectively.
