Direct Sensor-Oriented Calibration of the Projector in Coded Structured Light System

2008

Today, close range photogrammetry is known as an accurate and automatic 3D geometric measurement method especially for 3D point features (targets), but unfortunately it needs human supervision for 3D surface measurement due to nature of image matching problem. Therefore, in the last decade, coded structured light technique surpasses as one of the main complementary automatic and precise 3D surface measurement methods in different industrial and medical applications. Regardless of hardware considerations, the accuracy of structured light method highly depends on system calibration issue. Calibration of the projector, which is one of the major components of the structured light system, is a very difficult, time-consuming and expensive process. In this paper, the close range photogrammetry method is utilized for direct calibration of a projector. The experiments demonstrate the proposed method not only is a low-cost and high-speed process but also is capable to calibrate the projector ...
