Spatial location in 360$^{\circ}$ of reference points over an object by using stereo vision

Abstract


Stereo Vision is a powerful tool used to get a 360$^{\circ}$ scan of an object in order to obtain topography details or getting the spatial position of a given set of points of interest. However, the required computational time could be slow to perform real-time measurements. In this work we present an alternative approach based on Hering's coordinate system and the use of high reflective markers, used as reference points to track an object movement. The advantage of using these markers is that their detection is faster than a full scene correlation since it is performed by matching the position of the centroids of each marker without using any pixel-by-pixel analysis.

Keywords


Hering's coordinates; stereo vision; track markers
