摘　　要：裸眼立体显示技术普遍存在视角范围受限、串扰严重、甚至存在逆视区域等问题。基于双目视觉与人脸跟踪的方法,根据人脸的空间坐标控制背光方式,在全分辨率裸眼立体显示的基础上实现了视区空间的无缝覆盖;并进一步采用ROI方法能程序运行帧率提升至20 f/s(帧/秒)以上,从而实现时间上的无缝切换。实验证明,基于此技术所研制的系统能满足人脸实时跟踪需求,实现空间与时间无缝的裸眼3D图像显示。Generally, many problems were found in auto-stereoscopic display technology, such as the limitation of visual angle and serious crosstalk, even as the areas with pseudoscope problem. The article was based on the method of binocular vision and face tracking. On the basis of the full resolution auto-stereoscopic display system, the seamlessness of the visual volume was achieved by controlling the backlight according to spatial coordinates of faces Further more, the frame rate of the program with ROI method was increased to 20 frames/sec or more, and thus the seamless switching came true. It was shown that the needs of real-time face tracking can be satisfied and spatially and temporally seamless auto-stereoscopic display can be achieved by experiences.
