Abstract:In order to solve the frequent occurrence of traffic accidents and escape cases in China, the author studies the tire trace characteristics and trace width data according to the experimental tire traces and the characteristics of tire traces on the accident site, and analyzes and judges the nominal section width of the tire specifications. Apply the Visual C++ program development platform to develop vehicle tire information management software, and query vehicles that meet the tire specifications to reduce the scope of suspected vehicles. Through the experiment, the trace image database is established, and the Matlab software is used to further identify and match the tire trace image to find the best matching result. Finally, it is very important to quickly locate the suspected vehicle and detect the escape case.
