Abstract

This paper deals with the comparison of the presented approach to the another subpixel corner detectors. The our proposed and considered detection method uses the regular cornerness map obtained from the usual corner detectors as initial step. The main idea is to use the cornerness values from a neighboring area around found corner point as a 3D profile object and to find the coordinates of its centroid. As the subject of this comparison the determination procedure of the mutual displacement between two corresponding cameras using image stereo pair and prior information coming from camera calibration was used. This whole process of distance estimation consists of multiple steps which are also briefly explained on the next pages. The all results were statistically analyzed, listed in a table and turned into specific findings and conclusions.
