STRUCTURED LIGHT MATCHING OF A SET OF CURVES FROM TWO CAMERAS

摘要

A method for matching points between three images of a scene comprises retrieving three images acquired by a sensor, extracting blobs from said reflection in said two images; for each given extracted blob of the first image: selecting a selected epipolar plane; identifying plausible combinations; calculating a matching error; repeating the steps of selecting, identifying and calculating for each epipolar plane of the set of epipolar planes; determining a most probable combination; identifying matching points between the two images; validating the matching points between the two images, said validating comprising for each pair of matching points, determining a projection of the pair of matching points in a third image of the third camera, determining if the projection of the pair of matching points in the third image of the third camera is located on a blob, identifying the pair of matching points as validated if the projection of the pair of matching points in the third image of the third camera is located on the blob; providing the validated pairs of matching points.
