Automatic Correspondence and Registration of Range Images for 3D Modeling

Automatic registration of range images is a fundamental problem in 3D modeling of free-from objects. Registration is usually performed in two steps. First, the range images (views) are coarsely registered and then this registration is iteratively refined with an algorithm like ICP for example. Automatic coarse registration can be performed either through system calibration or through feature matching (also known as automatic correspondence establishment). Our contribution is in the area of automatic correspondence establishment. The following paper describes our automatic pairwise correspondence algorithm.

We also extended our above work to multiview correspondence which we define as a one-to-many correspondence (or matching) approach whereby one view is simultaneously matched with multiple views. Our multiview correspondence algorithm can automatically establish correspondences between N unordered views of an object with O(N) complexity. Unordered means that the order in which the views were acquired is unknown and hence there is no prior knowledge about which view pairs overlap. The following paper describes our multiview correspondence algorithm.
