INTERPRETATION OF 2D AND 3D BUILDING DETAILS ON FACADES AND ROOFS
Facades roofs semantic segmentation aerial images street side images multi view
2014/5/8
Current Internet-inspired mapping data are in the form of street maps, orthophotos, 3D models or street-side images and serve to support mostly search and navigation. Yet the only mapping data that cu...
基于头部追踪的宽视角裸眼3D显示系统
头部追踪 裸眼3D显示 液晶光栅
2014/3/20
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。
