摘要:
A system and method for extracting structure from stereo that represents the scene as a collection of planar layers. Each layer optimally has an explicit 3D plane equation, a colored image with per-pixel opacity, and a per-pixel depth value relative to the plane. Initial estimates of the layers are made and then refined using a re-synthesis step which takes into account both occlusions and mixed pixels. Reasoning about these effects allows the recovery of depth and color information with high accuracy, even in partially occluded regions. Moreover, the combination of a global model (the plane) with a local correction to it (the per-pixel relative depth value) imposes enough local consistency to allow the recovery of shape in both textured and untextured regions.
