| Research Abstract |
Streo matching technique contains various algorithms to extract the three dimensional information from TV or CCD image. In this study several algorithem have been compared and evaluated using images tgaken by color TV camera at the outside. Before executing the stereo matching proceduce, the basis for color space of image is transformed from RGB into HSV or HSL, and then the principal component analysis method is applied to the transformed images. Zero crossing method detects the edge part in the first principal compornent images. Edge matching procedure is preformed for the distinctive lavels which consist of edge crossing lines. The accuracy of matching is examined about the cases adopting each of Cross correlation method, SSDA method and Fourier cross correlation method using edge matching result.
