The authors of this paper propose a method that addresses the existing challenges of using commonly available hardware to calibrate single-camera and single-projector structured light systems with pinhole lenses for 3D reconstructions; they explain the principles behind the proposed method, present experimental results, discuss the proposed calibration method practices and procedures, and in the final section, summarize the proposed work.
In this paper, the authors propose an innovative method for single-camera and single-projector structured light system calibration in that it eliminates the need for calibration targets with physical features. Instead, a digital display such as a liquid crystal display (LCD) screen is used to present a digital feature pattern for camera intrinsic calibration, while a flat surface such as a mirror is used for projector intrinsic and extrinsic calibration. To carry out this calibration, a secondary camera is required to facilitate the entire process. Because no specially made calibration targets with real physical features are required for the entire calibration process, the authors’ method offers greater flexibility and simplicity in achieving accurate calibration for structured light systems. Experimental results have demonstrated the success of this proposed method. (Publisher Abstract Provided)
