为了解决了常规裸眼3D显示器件视区固定, 且观看角度狭小的问题, 文中提出一种基于头部追踪技术的增大观看视角的解决方案。该方案可以通过头部追踪设备检测观看者所在的位置, 通过调整液晶光栅的透光位置, 使观看者的左眼与右眼分别位于最佳观看区域,在很大范围内, 观看者始终可以看到合适的3D图像。提出了头部追踪3D显示器件的测试评价方法, 通过实验室验证, 该方法能有效评价该类显示器件的性能。

Normal naked 3D display have some defects,such as fixed viewing point, narrow viewing angle. In order to enhance the 3D performance, a 3D display system base on head tracking is introduced. In this system, a camera detects the position of observer′s face, and a LC barrier moves the 3D viewing point toward the face simultaneously by changing its transmissive area. Thus the observer can receive good 3D images freely within the visual field of the camera. Because there is no meteyard for this wide viewing angle 3D display, this paper puts forward a test method.The experiment result proved the method is viable.
