Abstract

The invention discloses an embedded type vehicle type recognition system based on a virtual coil. The embedded type vehicle type recognition system comprises an external program and data memorizer, an external high-speed dynamic memorizer SDRAM, an image collecting device, an image AD sampling module, a power source control module, a dual-core DSP digital signal processor chip, a virtual coil distinguishing unit and a vehicle type recognition unit. The image AD sampling module is used for acquiring the video image date provided by the image collecting device. The dual-core DSP digital signal processor chip is used for calling the virtual coil distinguishing unit to carry out virtual coil distinguishing on the collected video image to select the keyframe image emerging when a vehicle appears. The dual-core DSP digital signal processor chip is used for calling the vehicle type recognition unit to carry out vehicle type recognition calculation on the keyframe image. The embedded type vehicle type recognition system can extract characteristic values about the vehicle from the video image information and carry out structuring description with the cooperation with the virtual coil, the type of the vehicle in the video image can be recognized, and a video monitoring system can be applied and managed intelligently and conveniently.

Description

technical field [0001] The invention relates to a vehicle recognition technology, in particular to a vehicle type recognition technology. Background technique [0002] In recent years, along with the rapid development of my country's national economy, the coverage area of ​​roads has continued to expand, and the traffic volume has also increased. However, most roads still use the method of manually judging vehicle models, which causes huge personnel and time costs, and restricts development of the transportation industry. In view of this situation, Intelligent Transportation System (ITS, Intelligent Transportation System) came into being. It is the frontier of transportation science and technology in the world. The internationally recognized service fields of ITS include: advanced traffic management system, travel information service system, commercial Vehicle operation system, electronic toll collection system, public transportation operation system, emergency management sy...
