Fusion based on a discrete implicit surface representation enables fast reconstruction for complex object modelling. However, surfaces are represented at a single resolution resulting in impractical storage costs for accurate reconstruction of large objects. This paper addresses accurate reconstruction of surface models independent of object size. An incremental algorithm is presented for implicit surface representation of an arbitrary triangulated mesh in a volumetric envelope around the surface. A hierarchical volumetric structure is introduced for efficient representation by local approximation of the surface within a fixed error bound using the maximum voxel size. Multi-resolution geometric fusion is achieved by incrementally constructing a hierarchical surface representation with bounded error. Results are presented for validation of the multi-resolution representation accuracy and reconstruction of real objects. Multi-resolution geometric fusion achieves a significant reduction in representation cost for the same level of geometric accuracy.","PeriodicalId":337843,"journal":{"name":"Proceedings.

Central to the model construction problem is the registration of range data, taken from different vantage points, into a common coordinate frame. This involves determining a transformation for each set of range data which aligns overlapping surface points in the common frame. Current registration algorithms have been developed specifically for rigid objects, but it is not obvious how these can be extended to articulated or more generally deformable objects. Here, we propose that range images of articulated objects are first segmented into their rigid subcomponents. Each subcomponent can then be registered in isolation using the existing algorithms designed specifically for rigid parts and the final model formed by reassembling all of the submodels. This has motivated the development of a rigid part segmentation algorithm which is described and demonstrated here. The algorithm is currently limited to non-umbilic surfaces, but in this more restricted domain is shown to work well.","PeriodicalId":337843,"journal":{"name":"Proceedings.
