Abstract: Stereo-footprint is a sort of vital trace evidence during the criminal detection. Thus making a higher accuracy feature extraction of the stereo-footprint is becoming more important. A smart system of stereo-footprint characteristics information collection-recognition is designed based on the relative verification theory. In the system, feature extraction is completed through CP35MHT80 which offered by wenglor, image extraction is gotten through C920 which is offered by Logitech and the software sections such as image acquisition, coordinate transformation, peripherals ranging module, and feature data processing etc. are completed through Labview, then the feature data matching are completed. At last, as the results show the system can make a speed stereo-footprint feature extraction and recognize the footprint. After that, a high quality stereo-footprint recognition report will show up.

Key words: stereo-footprint, feature extraction, trace examination, footprint recognition
