| Abstract: | This paper deals with a binocular 3-D computer vision system based on the hierarchicalmatching of edge features,Frei and Chen operator is used to extract the edge.The averagegradients of an image obtained by two isotropic operators are non-equal quantized andthresholded in an angle.Edge features are extracted after passing a preemphasis transferfunction which can equalize the noise affection.Binary edge images are decomposed into apyramid structure which is stored and searched using Illiffe's location method.Corre-sponding points are used to determine the range data using triangulation based on an im-proved Trivedi's formula.In calibration the authors set the optical axes of the two camerasparallel (?) simplify the calculation.A 3-rd order Householder transform is used to solve thecompatible coupled equations. |
