Shrink Wrapping Small Objects

open access: yes2015 12th Conference on Computer and Robot Vision, 2015
We consider the problem of scanning and modelling small objects using easily available RGBD sensors such as the Kinect. These sensors allow for the acquisition of view-based registered depth and color data. We register the point clouds by recovering the rigid transformation between successive pairs in a sequence of views, and then demonstrate the ...
