Projector Calibration Algorithm for the Structured Light Measurement Technique
A projector model is described in details,and a simple and accurate projector calibration method is proposed.In this method,the projector can be viewed as an inverse camera,and a plane calibration board with circle marks is used to calibrate the projector.During the calibration processing,two series fringe patterns with different directions are projected onto the calibration board to establish accurate projector image and camera image correspondence.Thereby,the projector calibration dataset can be generated.Then the projector can be calibrated using a well established camera calibration algorithm.The experiment results show that the projector calibration algorithm proposed in this work is easy to operate and precise.The calibration precision can achieve 0.312 pixel.
