Abstract
Systems, methods and computer apparatuses for computing three dimensional (3D) surfaces are described herein. An embodiment includes constructing a slanted voxel grid oriented in a direction between at least two camera locations, projecting images from respective camera locations onto the constructed voxel grid, calculating, for one or more voxels in the voxel grid, a magnitude of difference between pixels corresponding to respective projected images to provide a difference value for each of the one or more voxels, and computing a three dimensional surface passing through voxel locations corresponding to one or more calculated difference values of the one or more voxels. In an embodiment, the three dimensional surface is computed as a surface passing through voxel locations corresponding to calculated difference values having lower magnitudes with respect to other calculated difference values.
