  • Patent number: 8405716
    Abstract: A folding optical path transfer videometrics method for measuring the three-dimensional position and attitude of non-intervisible objects is disclosed. In one aspect, the method includes the following: constructing a folding optic path between an invisible target and a reference, disposing transfer station comprising a camera, a cooperating mark and a laser range finder on each break point in the folding optic path. The method may further include processing an image shot by each camera, accounting for the distance measured by the laser range finder, obtaining a position and posture information corresponding to each adjacent transfer station, summing the values from the reference to the invisible target, and achieving three-dimensional position and posture of the invisible target relating to the reference.
