Robust real-time vehicle detection and tracking method

Abstract

The invention discloses a robust real-time vehicle detection and tracking method, which mainly solves the problems that the vehicle tracking method cannot realize stable tracking, the real-time performance is poorer, the realization is more complex, and demands of people cannot be met in the prior art. The robust real-time vehicle detection and tracking method comprises the steps of collecting positive and negative samples; extracting characteristics of the positive and negative samples to obtain a cascade classifier; detecting target pictures; establishing a tracking list and predicting positions of vehicles in the tracking list by adopting an optical flow method; and conducting path tracking according to the initial positions and the predicted positions of the vehicles. By adopting the scheme, the robust real-time vehicle detection and tracking method achieves the goals of stable tracking, better real-time performance and relatively simple realization, and has very great practical values and popularization values.

Description

technical field [0001] The invention relates to a monitoring method, in particular to a robust vehicle real-time detection and tracking method. Background technique [0002] With the gradual implementation of national policies on "Safe City" and "Safe Traffic", the field of intelligent video surveillance has developed rapidly. At present, most of the vehicle detection systems used in the field of intelligent video surveillance rely on static backgrounds, and feature judgments and trajectory predictions are performed by extracting moving object information. It has a great impact on the detection. In order to improve the detection accuracy, complex algorithms are often used to separate the background in the prior art. Although this processing method achieves the purpose of accurate detection, it cannot meet the real-time requirements. [0003] Vehicle tracking is an indispensable part of the monitoring system. The research on tracking algorithms has been a hot field in recent...
