A method and apparatus for trajectory tracking of an object

Abstract

The invention provides a target track tracking method and a device, which relate to the technical field of intelligent video surveillance. The target track tracking method comprises the following steps: carrying out structured processing on the target characteristic map of the target object to obtain the target structured information of the target object; in the preset structured information database, history structured information matching the target structured information, history characteristic map corresponding to the history structured information and the terminal position of the monitoring end for sending the history characteristic map are searched; in a preset identity information database, acquiring an identity mark corresponding to a history characteristic map and a GPS positioning position of a mobile communication number corresponding to the identity mark; if the position of the terminal matches the position of the GPS positioning, the movement trajectory of the target object can be obtained by counting the position of the terminal, which achieves the technical effect of determining the identity authentication and trajectory tracking accurately through the mass surveillance video.

Description

technical field [0001] The invention relates to the technical field of intelligent video monitoring, in particular to a method and device for tracking a target trajectory. Background technique [0002] At present, with the explosive growth of image surveillance videos, it is far from enough to meet the needs of human faces and pedestrians with naked eyes alone. How to efficiently and accurately determine identity authentication and track tracking through massive surveillance videos has become an urgent problem to be solved. Face recognition is the easiest way to obtain identity authentication, but in surveillance video, due to camera resolution and shooting angle, it is usually impossible to get very high-quality face pictures. When face recognition fails, pedestrian re-identification becomes a very important alternative technology. However, suspects usually evade pursuit by camouflaging hairstyles, wearing masks or changing clothes. The accuracy of pedestrian re-identifica...

Problems solved by technology

However, suspects usually evade pursuit by disguising hairstyles, wearing masks or changing clothes. The accuracy of pedestrian re-identification technology still cannot meet the needs of large-scale practical applications.
