One of the main components of the computer vision is 3D reconstruction. Extracts and the match based on two-dimensional picture characteristic point is the 3D reconstruction technology core. Taking binocular stereoscopic vision theory as a foundation
through extracts the characteristics of SURF based on the multi-scale analysis
this feature has specific scale reproducibility
put the epipolar constraints and disparity constraints as conditions judgement to specific screening
it is greatly reduced the search range. The experiment use the matching method for three different actual scenes
the results shows that the method can enhance the image matching speed and precision
and can get more precise dense parallax
used for reconstruction complete scene. 2012 IEEE.
