Abstract

The calibration of the projector is essential in existing monocular structured light measurement systems, and its parameters are not only the basis for measurement, but the parameter accuracy also has a direct impact on the measurement results. The calibration plate cannot be photographed directly by the projector, and it is generally necessary to use a camera to give the projector the ability to photograph it, making the calibration process relatively complex. In this paper, projector calibration is carried out by calculating the coordinates of the projector images of the corner points of the calibration plate using a color tessellated calibration plate, using a method based on radial basis function interpolation. Only two photos are needed to find the image coordinates of the corner point on the projector, and the method has high flexibility and accuracy. The performance of the method is experimentally verified with a calibrated reprojection error of 0.0808 pixels, the number of images used was reduced by 90% and the time for calibration was reduced by 95% compared to the original method, which can be used in the calibration of projectors for structured light systems.
