Abstract
Aspects of the present invention include feature point matching systems and methods. In embodiments, a tree model is used to find candidate matching features for query feature points. In embodiments, the tree model may be pre-learned using a set of sample images, or alternatively, the tree model may be constructed using one or more of the input images. In embodiments, features in one of the stereo images are registered with the tree model, and then features from the other stereo image are queried through the tree model to identify their correspondences in the registered stereo image. As compared to prior brute force matching methodologies, embodiments disclosed herein reduce the complexity and calculation time for determining matching feature points in stereo images.
