Abstract

The invention relates to an automatic motorcycle type identification system and method based on high-speed pulse laser scanning, belonging to the technical field of intelligent traffic management devices and methods. The automatic motorcycle type identification system comprises a high-frequency laser ranging module, a motorcycle outline drawing module and a motorcycle type identification module, the high-frequency laser ranging module and the motorcycle outline drawing module are vertically arranged above a lane. By using the method provided by the invention, the high-frequency laser ranging module is used for carrying out real-time pulse laser ranging and sending a distance value to the motorcycle outline drawing module, the motorcycle outline drawing module is used for drawing a distance parameter scanning graph in real time and sending the distance parameter scanning graph to the motorcycle type identification module, and the motorcycle type identification module is used for identifying a motorcycle type according to motorcycle outline information on the distance parameter scanning graph. Therefore, the invention effectively overcomes the defect of the prior art, and provides the automatic motorcycle type identification system and method with the advantages of simpleness in setting and maintaining, low cost, higher motorcycle identification rate and wide application range.

Description

technical field

[0001] The invention relates to the technical field of intelligent traffic management equipment, in particular to the technical field of vehicle identification, in particular to a vehicle automatic identification system and method based on high-speed pulsed laser scanning. Background technique

[0002] With the increasingly prominent problems of traffic congestion and congestion, as well as the continuous development of computer technology, Intelligent Transportation System (ITS) has been more and more widely used, and is widely used in developed countries such as Europe and the United States. It has been applied, but the application in our country is still in the initial stage of exploration and research. Vehicle detection, tracking and vehicle identification are important branches in the application field of ITS, and they are also relatively weak technical links at present.

[0003] Vehicle type automatic identification is the premise of ITS for vehicle cl...
