Meaningful Matches in Stereovision

Pseudo Stereovision System (PSVS): A Monocular Mirror-based Stereovision System

For the autonomous movement of a robotic system, in real time, it has to perceive its environment, to calculate the position of a target or of a block and to move properly. For this reason, many types of sensors and apparatus have been proposed. The target state is required to be accurately calculated and a desired task or procedure to be safely and successfully integrated. In cases of limited ...

Do Weave Matches Imply Canvas Roll Matches?

Computational algorithms for measuring thread counts from scanned x-rays produce warp and weft thread count “maps” across entire paintings. Within the database of over 300 van Gogh paintings, we found a clique of 44 warp-weave-matched paintings. By reconstructing the smallest canvas section that could have produced this match, they must span the entire width of a commercial canvas roll (2+ mete...

Trinocular Stereovision: Recent Results

We present an original approach to build rapidly and reliably a 3D description of the environment of a mobile robot by means of passive stereovision using three cameras. This technique has been successfully applied to many indoor scenes and has proved faster than a previously developed binocular stereo technique, while providing more reliable and more accurate results. Moreover, the algorithm i...

Stereovision: beyond disparity computations.

One of the most powerful sources of information about three-dimensional (3-D) structure is provided by stereovision (or stereopsis). For over a century, theoretical and empirical investigations into this ability have focused on the role of binocular disparity in generating percepts of 3-D structure. Recent work in image segmentation demonstrates that stereovision can cause large changes in perc...
