Abstract
An active 3D acquisition system is presented that is based on the projection a simple pattern of squares. Through the observation of the projected pattern, and assuming pseudo-orthographic projection, the 3D shape of the scene can be retrieved up to a single parameter, that can be determined through a particularly simple calibration. An algorithm has been developed to automatically detect the lines and crossings of the projected pattern in the image. Experiments on a variety of scenes show that the algorithm is robust and provides accurate 3D reconstructions. Its one-shot operation enables the system to retrieve the shape of moving objects.Keywords
