Abstract

For an active robot vision system, the 3D sensor is often moved to several viewpoints around the object for acquisition of the features of interest. In such a case, its configuration needs to be changed for better perception of the different features. This paper introduces the 3D vision system and investigates the self-recalibration problem in a structured light system with six degrees of freedom in which the sensing configuration is changeable. The relative pose between the projector and camera of the system is calibrated by taking a single view of the scene, so that the 3D measurements and reconstruction can be performed immediately when and if the configuration of the system is changed. A unique color encoding method is used so that only one image is required for the 3D reconstruction.
