Abstract
Described are methods, systems, and apparatus, including computer program products for finding correspondences of one or more parts in a camera image of two or more cameras. For a first part in a first camera image of a first camera, a first 3D ray that is a first back-projection of a first feature coordinate of the first part in the first camera image to a 3D physical space is calculated. For a second part in a second camera image of a second camera, a second 3D ray that is a second back-projection of a second feature coordinate of the second part in the second camera image to the 3D physical space is calculated, wherein the first feature coordinate and the second feature coordinate correspond to a first feature as identified in a model. A first distance between the first 3D ray and the second 3D ray is calculated.
