摘要
A computer-implemented method for finding correspondences of one or more 2D sub-instances in a camera image of two or more cameras comprising: a) locating (315) the one or more 2D sub-instances in a first camera image of a first camera and a second camera image of a second camera; b) finding (320) feature coordinates for each of the 2D sub-instances in the first and second camera images based on 3D feature points of a model of a part; c) generating a correspondence candidate list ((425, 445), (425, 450), (430, 445), (430, 450)) of correspondence candidates with combinations produced by selecting a 2D sub-instance from the image of each camera; d) for a first found 2D sub-instance in the first camera image of the first camera, calculating a first 3-D beam representing a first backprojection (475) of a first found feature coordinate of the first found 2D sub-instance in the first camera image to a 3-D physical one Space is; e) for a second found 2D sub-instance in the second camera image of the second camera, calculating a second 3-D beam representing a second backprojection (480) of a second found feature coordinate of the second found 2D sub-instance in the second camera image to the 3D physical one Space, wherein the first found feature coordinate and the second found feature coordinate correspond to a first feature as identified in the model; and f) calculating a first distance between the first 3-D beam and the second 3-D beam, further comprising: g) for the first found 2D sub-instance in the first camera image of the first camera, computing a third 3-D beam containing a third Rear projection of a third found feature coordinate of the first found 2D sub-instance in the first camera image to the 3D physical space is ...
