It is difficult to make stereo matching in distance measurement based on binocular visionand the efficiency is low.To solve the problemswe proposed a new method based on corner detecting and manual matching.The basic theory of binocular vision based distance measurement was presented.The cameras were calibratedand stereo rectification of binocular vision system was realized d by using arithmetic of Bouguet.Then the method proposed by J.Shi and C.Tomasi was used to extract the subpixel corner pointswhich belonged to the same featurepoint of the target in the left and right images.Finallythe coordinates of the matched corner points and distancemeasuring formula were used to implement the distance measurement.
