提出了一种标定通用结构光系统的方法，该系统由一台摄像机和一台投影仪组成。所提出的方案是基于为结构光系统中的两个器件定义唯一的坐标系，从而在变换过程中引入刚性约束。这个约束被用来导出一个简单的函数，用于同时估计参数，从而得到更可靠的参数。文中以两种不同结构光系统的标定为例，说明了该方法的性能。©2004光电仪器工程学会。(DOI：10.1117/1.1635373)
A procedure is proposed to calibrate a generic structured light system, consisting of one camera and one projector. The proposed pro- cedure is based on defining a unique coordinate system for both devices in the structured light system, and thus, a rigidity constraint is introduced into the transformation process. This constraint is used to derivate a simple function for the simultaneous estimation of the parameters, result- ing in parameters that are more reliable. The performance of the pro- posed procedure is shown on examples of the calibration of two different structured light systems. © 2004 Society of Photo-Optical Instrumentation Engi- neers.
