本文讨论了一种使用时间编码结构光系统获得精确三维测量的方法。这项工作的一个目标是平衡系统中所有组件的准确性。这是通过在构成结构光系统的照相机和投影仪的模式中包括透镜失真来实现的。此外，子条纹估计被用来估计投影仪条纹值，作为子像素估计用于定位图像特征的补充。实验评估表明，它是重要的，使用子条纹估计，并将透镜失真的投影机模型。
This paper discusses a method for obtaining accurate 3D measurements using a temporally encoded structured light system. An objective of the work was to have a balance in the accuracy of all components in the system. This was achieved by including lens distortion in the modes for both the camera and projector which comprise the structured light system. In addition, substripe estimation was used to estimate projector stripe values as a complement to subpixel estimators used for locating image features. Experimental evaluation shows that it is important to use substripe estimation and incorporate lens distortion in the projector model.
