    摘要： A method of merging point clouds, comprising: generating reconstructed surface points in a first counterposed channel's point cloud; generating reconstructed surface points in a second counterposed channel's point cloud; identifying, for a selected reconstructed surface point in the first counterposed channel's point cloud, reconstructed surface points in the second counterposed channel's point cloud that are near an imaging system ray for the selected reconstructed surface point in the first counterposed channel's point cloud; calculating a projection of each of the identified near points in the second counterposed channel's point cloud onto the imaging system ray for the selected reconstructed surface point in the first counterposed channel's point cloud; calculating an average projection of each of the identified near points in the second counterposed channel's point cloud onto the imaging system ray of the selected reconstructed surface point in the second counterposed channel's point cloud; and moving the selected reconstructed surface point in the first counterposed channel's point cloud along its imaging system ray a portion of the distance towards the calculated average projection of each of the identified near point in the second counterposed channel's point cloud.

    摘要： A system (1100) for generating a three-dimensional height image of a reflective test target, the system comprising a plurality of illumination sources (1102) configured to generate a patterned illumination (1108) having a repeated pattern on the test target (1106); a plurality of cameras, each camera (1104) being configured to acquire an image of patterned illumination on the test target (1106) from a different azimuthal angle; the illumination sources (1102) and cameras (1104) being aligned relative to the test target (1106) and each other such that the camera (1104) acquires a specular image of the patterned illumination (1108) on the test target from at least one of the illumination sources. The system (1100) further including a controller (1454) coupled to the illumination sources (1102) and cameras (1104), the controller being configured to generate a height image of the test target (1106) by combining height images generated from each specularly aligned pattern illumination source and camera.
