Abstract

The invention relates to the technical field of video monitoring, and provides a target motion trail analysis method relating to two or more monitoring videos which can be invoked by a control center. The target motion trail analysis method comprises the following steps: confirming the first monitoring video in which a target appears; obtaining first time-space information and first target characteristics of the target according to the first monitoring video; confirming one or more monitoring videos taken around a first position; obtaining various object characteristics in the confirmed one or more monitoring videos, and confirming the second monitoring video from which the object characteristics obtained are matched with the first target characteristics with a similarity exceeding a preset threshold value; confirming the motion trail of the target according to second time-space information carried by the second monitoring video and the obtained first time-space information. The target motion trail analysis method has the advantages that the big data analysis function of cloud computing can be utilized for confirming the motion rail of the target in a plurality of monitoring videos, so that the target tracking efficiency is improved.

Description

【Technical field】

[0001] The invention relates to the technical field of video monitoring, in particular to a method and a monitoring system for target motion track analysis. 【Background technique】

[0002] The urban video surveillance system is an important part of a safe city. Cities at all levels have basically established a video surveillance network covering major areas, which has improved the city's security level.

[0003] Urban video surveillance is widely used in various types of police, providing support for command and dispatch, investigation and case solving. In the investigation and solving of crimes, the current video surveillance application is still dominated by manual inspection, and video intelligent analysis technology is gradually being promoted and used. Based on video intelligent analysis, it can quickly extract target features and quickly retrieve targets, which improves the efficiency of video investigation.

[0004] At present, cloud computing techn...
