Abstract | |||||||||||||||
| A 3D object--based depth estimation approach from stereoscopic image sequences is presented in this paper that introduces a memory for depth information from preceding image pairs. This approach is used in the EU--RACE project DISTIMA for applications like remote handling, quality control and TV post processing. Compared to depth estimation approaches that compute depth maps from consecutive stereoscopic image pairs independently by a triangulation of corresponding image points, the temporal coherence and accuracy of depth estimates is increased. The remaining depth estimation error variance is reduced and as a result of temporal filtering the effect of single outliers is reduced as well. 1. | |||||||||||||||
