系统标定对于任何三维形状测量系统都是至关重要的，通常涉及复杂且耗时的过程。在这项工作中，提出了一种新的系统的方法，准确和快速校准的三维形状测量系统，我们开发的结构光技术的基础上。关键概念是使投影仪能够像相机一样“捕获”图像，从而使投影仪的校准与相机的校准相同。有了这个新的概念，结构光系统的校准变得基本上相同的传统立体视觉系统，这是建立。该校准方法快速、稳健、准确。它大大简化了结构光系统的校准和重新校准程序。这项工作描述了所提出的方法的原理，并提出了一些实验结果，证明其性能。(c)2006年，由光学仪器工程师协会（Society of Photo-Optical Instrumentation Engineers）主办。
System calibration, which usually involves complicated and time-consuming procedures, is crucial for any 3-D shape measurement system. In this work, a novel systematic method is proposed for accurate and quick calibration of a 3-D shape measurement system we developed based on a structured light technique. The key concept is to enable the projector to "capture" images like a camera, thus making the calibration of a projector the same as that of a camera. With this new concept, the calibration of structured light systems becomes essentially the same as the calibration of traditional stereovision systems, which is well established. The calibration method is fast, robust, and accurate. It significantly simplifies the calibration and recalibration procedures of structured light systems. This work describes the principle of the proposed method and presents some experimental results that demonstrate its performance. (c) 2006 Society of Photo-Optical Instrumentation Engineers.
