Paper Abstract

Three-dimensional reconstruction method of a straight homogeneous generalized cylinder model using "axis-based stereo" , and contour line segmentation method are described. To achieve the axis-based stereo matching, stereo contour images are used. In each contour image, a pair of contour line segments are assumed to be the extremal contour of a cylinder and are interpreted as a "ribbon". A pair of ribbons over the stereo contour images are interpreted as a "cylinder". The cylinder's axis is determined by the stereo match of two ribbon's axes in space. For the line segmentation, an interval tree structure is built taking feature points as the curvature extrema using Scale-space analysis, and splitting the feature points' interval recursively to satisfy a line regularity. As a result of the line segmentation and reconstruction, actual human arms are recovered and recognized by the prototype vision system.
