- Abstract
- Depth discontinuities (aka depth edges) play a very important role in many appearance based approaches to computer vision problems because they represent object contours. This research shows that structured light imaging can efficiently be used to capture depth edges without 3D reconstruction. We strategically project structured light and exploit distortion of light pattern in the structured light image along depth discontinuities to reliably detect depth edges. However, in reality, distortion along depth discontinuities may not occur or be large enough to detect depending on the distance from the camera or projector. We have presented the method that guarantee the occurrence of the distortion along depth discontinuities for a continuous range of object location. Experimental results show that the proposed methods accurately detect depth edges of shapes of human hand and body as well as general objects.
