Abstract

This paper presents a novel dense motion capture technique which creates a temporally consistent mesh sequence from several calibrated and synchronised video sequences of a dynamic object. A surface patch model based on the topology of a user-specified reference mesh is employed to track the surface of the object over time. Multi-view 3D matching of surface patches using a novel cooperative minimisation approach provides initial motion estimates which are robust to large, rapid non-rigid changes of shape. A Laplacian deformation subsequently regularises the motion of the whole mesh using the weighted vertex displacements as soft constraints. An unregistered surface geometry independently reconstructed at each frame is incorporated as a shape prior to improve the quality of tracking. The method is evaluated in a challenging scenario of facial performance capture. Results demonstrate accurate tracking of fast, complex expressions over long sequences without use of markers or a pattern. © 2011 IEEE.
