ABSTRACT
3D reconstruction for intricate objects such as mesh structures or translucent materials is a challenging task. One way to form the shape of an intricate object is to probe its silhouette. We propose a 3D reconstruction system based on planar cast shadows and the shape from silhouette algorithm. Our work focuses on simplifying the calibration procedure and equalizing the numbers of effective pixels of shadows in all captured images. With this design, the spatial resolution is improved and it is able to carve intricate shapes.
