Urban target trajectory tracking method

Abstract

The invention proposes an urban target trajectory tracking method, and the method comprises the following steps: setting an intersection monitoring device; recording road behaviors of a pedestrian; determining a tracked target; and judging the trajectory of the tracked target. The method monitors the pedestrian on a road in real time through a camera at an intersection, carries out the analysis, processing and human face comparison of a video stream transmitted by the camera, obtains a human face target, deduces the walking trajectory of the human face target, and then deduces the disappearance range of the target through curve fitting. The method is low in cost, is high in flexibility, is wide in search range, is high in search accuracy, can be suitable for various types of target tracking application scenes, and provides assistance and support for various departments.

Description

technical field [0001] The invention relates to a tracking technology, in particular to a method for tracking a city target track. Background technique [0002] Although the modern society is developing in a peaceful and stable situation, there are still many fugitive suspects threatening people's safety. Some of the target detection systems used by the Public Security Bureau have the problem that the search range is not wide, and they cannot accurately locate the fugitives. It is a relatively accurate positioning target, but its own cost is too high to be widely used. Contents of the invention [0003] In order to solve the problem of inaccurate or accurate positioning but high cost of most existing target tracking technologies, this invention proposes a method for urban target track tracking, which monitors pedestrians on the road in real time through the camera at the intersection, and monitors the video sent by the camera. Stream analysis and processing, face comparis...

Problems solved by technology

[0003] In order to solve the problem of inaccurate or accurate positioning but high cost of most existing target tracking technologies, this invention proposes a method for urban target track tracking, which monitors pedestrians on the road in real time through the camera at the intersection, and monitors the video sent by the camera. Stream analysis and processing, face comparison, acquisition of the tracking target and the introduction of the tracking target’s walking trajectory, and the inference of the target’s disappearance range through curve fitting, which has the advantages of low cost, high flexibility, wide search range, and high search accuracy. , to provide assistance and support for multiple departments (such as the Public Security Bureau)
