Abstract

Complicated and time-consuming system calibration is indispensable for existing accurate three-dimensional reconstruction methods. To address this problem, this paper presents a simple and accurate optimized 3D reconstruction model based on a coaxial structured light system (CSLS). Compared to the traditional structured light system, CSLS contains a perspective projection unit and a telecentric imaging unit. Instead of obtaining the complicated structured light system parameters, the proposed model only requires the retrieval of a product matrix which could be easily calibrated by using an ordinary white plane. The influence of geometric distortion in the projector lenses has also been considered to further improve the measuring accuracy. Experiments were carried out to verify the validity of the proposed method.
