Vehicle searching method and system based on user-defined features

Abstract

The invention relates to a vehicle searching method and system based on user-defined features. The method includes the steps of firstly, extracting features of each vehicle in a vehicle image database shot by a monitoring camera and storing the features; secondly, searching for the vehicle, satisfying the user-defined features, in the vehicle image database shot by the monitoring camera and feeding back the searching result. The system comprises a vehicle image data reading device, a vehicle area positioning device, a vehicle feature extracting device, a vehicle feature storage device, a vehicle searching device and a searching result displaying device. According to the vehicle searching method and system, diversified searching methods can be provided, a user can search for the vehicle according to the user-defined features in the practical situation, the number of images which are manually confirmed by personnel who handling cases is greatly lowered, labor and materials are effectively saved, the case handling efficiency is greatly improved, and very good social benefits and economic benefits can be produced.

Description

technical field [0001] The invention belongs to content-based image search technology, in particular to a vehicle search method and system based on self-defined features. Background technique [0002] At present, with the popularization of surveillance cameras, surveillance cameras have basically been deployed in all major, medium and small cities across the country. A large number of vehicle images can be captured every day, and a city generates a huge amount of data every day, which provides very rich data for the traffic department and public security organs to detect various traffic accidents and criminal crimes.
