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 picture characteristic point,based on the wavelet transformation sub-line segment match method.The points between the two endpoints of the sub-line segment are matched quickly using acceleration way.This method proposes a good solution for balance problem between match precision and match speed.The thickness of cement clinker in the cooler is measured using this method.The experiment shows this method can enhance the picture match the speed and the precision,can be more precise to the object implementation three dimensional reconstruction.
