Abstract

It is challenging to capture a highly accurate 3D shape of a target object using a projector-camera pair. Attempts have been made using the pinhole model to represent the camera and projector geometry and a cubic object to estimate calibration parameters. The projector cannot emit light stripes through the same pinhole when scanning by a rotatable mirror. In addition, it is preferable to estimate the parameters using a two-dimensional object. In this paper, the problem of calibrating a structured light rangefinder is addressed. Unlike previous work, the projection of a light stripe from the projector is expressed by the equation of a plane. The coefficients of each light stripe's equation are estimated by observing a reference plane from unknown viewpoints. Experimental results demonstrate a high degree of accuracy compared to conventional methods.
