摘要	Image matching is one of the most challenging stages in 3D reconstruction, which usually occupies half of computa- tional cost and inaccurate matching may lead to failure of reconstruction. Therefore, fast and accurate image match- ing is very crucial for 3D reconstruction. In this paper, we proposed a Cascade Hashing strategy to speed up the image matching. In order to accelerate the image matching, the proposed Cascade Hashing method is designed to be three- layer structure: hashing lookup, hashing remapping, and hashing ranking. Each layer adopts different measures and filtering strategies, which is demonstrated to be less sensi- tive to noise. Extensive experiments show that image match- ing can be accelerated by our approach in hundreds times than brute force matching, even achieves ten times or more than Kd-tree based matching while retaining comparable accuracy.
