Resampling of multiple camera point cloud data

Even though the sampling grid of a digital camera is uniform and rectangular, the depth information reconstructed from multi-camera samples is neither uniform nor rectangular due to the rotations and translations of the camera coordinate systems with respect to each other. In order to facilitate further processing, e.g. compression of multi camera depth data, resampling of non-uniform multi-camera depth samples to a uniform rectangular grid is advantageous. In this paper, we introduce and compare two resampling methods using a voxel-based and a triangular-mesh-based approach.
