Fusing Stereo Measurements into a Global 3D Representation
Abstract: The report describes the thesis project with the aim of fusing an arbitrary sequence of stereo measurements into a global 3D representation in real-time. The proposed method involves an octree-based signed distance function for representing the 3D environment, where the geomtric data is fused together using a cumulative weighted update function, and finally rendered by incremental mesh extraction using the marching cubes algorithm. The result of the project was a prototype system, integrated into a real-time stereo reconstruction system, which was evaluated by benchmark tests as well as qualitative comparisons with an older method of overlapping meshes.
