A suite of software tools that manages all of the above phases (excluding the acquisition planning phase, onto which we are now working): [1] MeshAlign v.2: the module allows the registration of multiple range maps; it adopts a classical approach based on a pairwise local and global alignment, implemented with a number of innovations to reduce the user contribution, to improve efficiency and easy of use, and finally to support the management of a large number of range maps (we processed up to six hundreds range maps). [2] MeshMerge: the module allows the reconstruction of a single 3D mesh out of a set of registered range maps. Two different approaches were implemented: a classical volumetric reconstruction approaches based on distance field and a new approach characterized by a lower space complexity, higher efficiency and improved accuracy with respect to the previous, but more sensible to the alignment residual error. [3] MeshEdit: the module allows to perform simple editing actions on the mesh(e.g. to fill small holes, to remove non-manifold components of dangling edges/faces, to apply smoothing filters, etc). [4 and 5] MeshSimplify and Weaver complete the suite.
