Abstract:

Based on the existing video detection algorithms and the needs of intelligent transportation system,this paper builds a vehicle detection system which includes client module,named pipe communication module,feature extraction module,trajectory data processing module and database storage module.The system can detect and track the road vehicle,calculate the target vehicle data,collect the road data,query the history information and so on.The site test and on-line operation demonstrate that the vehicle detection system has high detection accuracy,strong overall performance,stable system operation and can meet the requirements of road administration.

Key words: video detection algorithm, vehicle detection, system design
