Abstract: To choose matching points for an object in stereo images is a key technique in disparity location and can influence precision of 3D location badly.Aiming at flaw location based on radiography,a kind of corresponding choosing technique based energy center matching is proposed.The influence of miss-matching on location precision is discussed firstly.Then the technique in the paper is compared with the common stereo location techniques.The experimental results show that the methods,which choose edge points or shape centers as corresponding points,can introduce biggish location error,but the technique brought forward in the paper can improve location precision greatly.

Key words: 3D localization, binocular vision, stereo matching, energy centre
