直接投影增强现实技术的若干问题（DirectAR）的问题：由于非平面表面，投影可能会发生几何失真（几何失真）;由于投影仪的位置与用户视点的位置不同，用户无法按预期看到投影（视点无关投影）;投影可通过表面颜色进行调制（辐射失真）;当投影倾斜朝向表面时，投影区域可能没有均匀的亮度（不均匀投影）。我们提出了一个综合框架来处理所有问题。实验结果表明，表面无关的DirectAR不可避免的问题，可以成功地解决。
Some issues on direct-projected augmented reality (DirectAR) are addressed: the projection may be geometrically distorted due to the non-planar surface (geometric distortion); the projection cannot be seen to user as intended because the position of the projector is not the same as that of the user’s viewpoint (viewpoint-ignorant projection); the projection may be modulated by surface color (radiometric distortion); the projected area may not have uniform brightness when the projection is obliquely headed for the surface (uneven projection). We propose an integrated framework for handling all the problems. Experimental results demonstrate that the problems unavoidable in surface-independent DirectAR can be successfully resolved.
