Abstract

An efficient method to reconstruct prismatic rigid objects by multiple camera arrangements is presented in this paper. The proposed method estimates accurately the dominant vanishing points in remarkably short time. First, concurrent multiple views from the distinct cameras
located at the upper corners of a room are used as the input to the algorithm. An implementation of the Radon transform is then applied in order to detect line segments across the respective views. An initial hypothesis about the existing vanishing points is made. The J-linkage algorithm is utilized to cluster the different groups of line segments and to refine the calculation of the respective vanishing points. The regions across the multi-camera system are then distinguished and the correspondences across the multiple views of the test room are obtained. Last, the volume of objects is estimated accurately with multiple cross ratios along the images and is represented by an octree decomposition technique.
