Object Tracking for Tangible Projection Mapping by using Multiple Contours

摘要

In this study, we propose a projection mapping method using contours viewed from multiple viewpoints to achieve high-precision tracking of objects that can be grasped and moved freely by hand. Recently, dynamic projection mapping, which changes the appearance of a moving object, has been actively studied. In particular, tracking a grasped object is difficult because the object is occluded. We have proposed a method for achieving high-precision object tracking using only ordinary infrared cameras. Nonetheless, there were still challenges that made it difficult to keep tracking. In this study, we propose a more robust and accurate object tracking by adding contours obtained from different viewpoints by increasing the number of cameras, which is more robust to occlusion and accurate.
