摘　　要：为实现面向动态场景的空间增强现实,提出了一种基于深度相机的连续实时投影标定方法。提出将深度相机安装在投影机上,组成投影机-深度相机系统,系统的处理流程包括离线的标定及初始注册阶段,以及在线的跟踪阶段,最终生成虚拟模型与真实投影表面的投影映射,实现了虚实物体的对齐。为了验证所提出的方法,搭建了一套原型系统,实验结果证明,所提出的方法可以实时、精确地实现空间增强现实应用中的动态投影标定。A depth camera based real-time projector calibration method for dynamic projection in Spatial Augmented Reality was proposed. To achieve this, a depth camera to the projector was attached to form a projector-depth-camera system. The processing flow has two phases： an off-line calibration and initial registration phase and an on-line tracking phase. The proposed system finally generated a projection mapping between the virtual model and the real projection surface. Thus, the virtual model was aligned with the real object. A prototype system was built to validate the method. Experimental results show that the method can continuously calibrate projection in real time with good performance.
