2A2-Q03 Measurement of the disparity at the infinity point by parallel lines for a stereo camera : One idea to keep the accuracy of distance measurement in a practical use(Localization and Mapping)

Abstract

New idea to keep the accuracy of distance measurement in a practical use is proposed. The property that parallel lines in the disparity space are converted to parallel lines in the real world under the accurate disparity offset is used. The experimental result shows that the correct disparity can be obtained within the accuracy of 0.05 pixels.
