Abstract

Structured light illumination is a widely spread approach for 3D shape reconstruction. Scanning the scene of interest with hard edge stripe via video projector is a very common implementation. During the scanning light planes are being projected across the space and their positions in time are needed to triangulate 3D position of some point. Traditionally, light plane equation is readily obtained in case of calibrated video projector. This paper presents a method where light plane positions are determined without explicit projector calibration. The comparison of traditional and proposed method showed no difference in terms of reconstruction accuracy. However, there are two major advantages of proposed method: end user can faster start using the system itself and system implementation is easier primarily in software sense. Also, successful method implementation for computer graphic application is shown.
