A vehicle search method and system based on user-defined features

Abstract

The invention relates to a vehicle search method and system based on self-defined features. The method includes: extracting and saving the features of each vehicle in the vehicle image database captured by a surveillance camera; The database is searched for vehicles satisfying the self-defined characteristics and the search results are returned. The system includes: a vehicle image data reading device, a vehicle area positioning device, a vehicle feature extraction device, a vehicle feature storage device, a vehicle search device and a search result display device. The method and system provided by the present invention can provide a variety of search methods, so that users can customize the search features according to the actual situation to search for vehicles, greatly reducing the number of images manually confirmed by case handlers, effectively saving manpower and material resources, and making case handling more efficient. The efficiency is greatly improved, and very good social and economic benefits can be produced.

Description

Technical field [0001] The present invention belongs to content-based image search technology, and particularly relates to a vehicle search method and system based on custom features. Background technique [0002] At present, with the popularity of surveillance cameras, surveillance cameras are basically deployed in all large, medium and small cities across the country. A large number of vehicle images can be captured every day, and a city generates massive amounts of data every day. This provides a wealth of data for the transportation department and public security organs to detect various traffic accidents and criminal crimes. [0003] When the traffic department and the public security organ detect a case, they usually only have a photographed image of the suspect vehicle, or even no image, with only some qualitative features. For example, they only know that the suspect vehicle is a black off-road vehicle. Where will it pass after the accident or crime? Several bayonet etc. ...
