This paper proposes an active solution to optimally recovering 3D scene depth from a sequence of pictures. Active vision, as referred to in this paper, is characterized by gaze control for input dependent data acquisition, coupled with a treatment of the reliability of the acquired information.
An active choice is described for choosing the difference between camera locations for the different pictures in the sequence. The trade-off between short and long distances between successive locations of the camera is shown in terms of occlusions, perspective transformation and exact triangulation.
The analysis also gives insight into the results and pitfalls of ordinary stereo.
