System of stereo-footprint data acquisition-recognition

摘要

Stereo-footprint is a vital trace evidence of criminal detection. Thus, it is important to make a high accuracy feature extraction of the stereo-footprint. In this paper, a system of stereo-footprint data acquisition-recognition is designed. 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 Labview2011. At last, as the results shows, the system can make a speed stereo-footprint feature extraction and recognize based on the relative verification theory. After that, a high quality stereo-footprint recognition report will show up.
