Abstract
A sequence of frames including color and depth data is processed to identify key frames while minimizing redundancy. A sparse 3D point cloud is obtained for each frame and represented by a set of voxels. Each voxel has associated data indicating, e.g., a depth and a camera viewing angle. When a new frame is processed, a new sparse 3D point cloud is obtained. For points which are not encompassed by the existing voxels, new voxels are created. For points which are encompassed by the existing voxels, a comparison determines whether the depth data of the new frame is more accurate than the existing depth data. A frame is selected as a key frame based on factors such as a number of new voxels which are created, a number of existing voxels for which the depth data is updated, and accuracy scores.
