Single-station multi-view global calibration based on the concentric circle 3D target

Abstract

In view of the disadvantage that traditional tracking 3D scanners can only use global binocular camera to complete single-station multi-view global calibration, a concentric circle 3D target (CC3DT) is designed in this paper. For the designed CC3DT, a single-station multi-view global calibration algorithm is proposed. This method only needs one camera to complete the global calibration function of global binocular camera. The designed CC3DT has simple structure and low cost. In this paper, the validity and feasibility of the proposed global calibration algorithm are verified by real experiments. It has widely application prospect and practical theoretical research value.
