Embodiment 1

[0019] Embodiment 1 of the present invention provides a method for target motion trajectory analysis, the method involves at least two or more than two video surveillance subsystems, such as figure 1 Shown in the video surveillance subsystem 1, video surveillance subsystem 2 ... video surveillance subsystem n, each video surveillance subsystem has an independent controller 11 (21 ... n1) and memory 12 (22 ... n2). In the actual implementation environment, the monitoring subsystem can be a plurality of monitoring areas divided under one management system by the traffic bureau based on the area; it can also be a monitoring system that represents a residential area; or A combination of the above two methods can be used, which is not specifically limited here. The monitoring video can be called by the control center 2 of the present invention, specifically, the control center 2 uses the Internet to connect to the controllers 11, 21...n1, and obtains the monitoring video stored in ...

Embodiment 2

[0022] Embodiment 2 of the present invention provides a method for target motion track analysis, the method involves at least two or more than two video surveillance videos, and the surveillance videos can be invoked by the control center of the present invention, such as figure 1 shown, including:

[0023] In step 201, the control center confirms that a first surveillance video of a target appears, and acquires first spatio-temporal information and first target features of the target according to the first surveillance video.

[0024] The first spatio-temporal information includes: first position information and first time information; in specific implementation, the first spatio-temporal information and the first target feature of the target can also be the picture object that is input by the operator. In the implementation manner of the invention, it is not limited to confirming the first spatio-temporal information and the first target features of the target from the first...

Embodiment 3

[0046] This embodiment is to specifically explain how to implement the collection strategy described in Embodiment 2. According to the content described in Embodiment 2, the collection strategy specifically includes: the collection of surveillance videos in each main direction in a circle centered on the first position is the end condition, so as to obtain the first One or more surveillance videos around the location; or, with the first location as the center and the specified length as the radius as the end condition, one or more surveillance videos within the circle are obtained; or, the first location is collected In a circle centered at a position, the designated surveillance video is included as an end condition, so as to obtain one or more surveillance videos around the first position; or, a combination of the above three methods is adopted.

[0047] For the first method, the end condition is to collect the surveillance video in the circle centered on the first position, i...

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...
