A new image-based algorithm named IEPVH is proposed to perform exact polyhedral visual hull reconstruction in an incremental fashion. First
edges of visual hull model are chopped by viewing cone of the new view. Second
local orientation information of intersection vertices on edges of visual hull model are retrieved and at the same time intersection vertices on edges of viewing cone are added into the mesh. Third
local orientation information of intersection vertices on the edges of viewing cone are retrieved. Finally
faces of viewing hull are identified by traversing edges of the new model and then triangulated for rendering. IEPVH enables interactions with users during the computation. Moreover
IEPVH has the merit of less memory consumption. Modeling results are presented to demonstrate IEPVH’s robustness and effectiveness. IEPVH’s merits make it preferred by mobile device.
