Embodiment Construction

[0015] The basic principle of the present invention is to use dense video monitoring equipment in cities, and to establish the topology structure of the video monitoring network in the GIS database by spatially locating the video monitoring equipment. Once a target is found somewhere, such as a criminal suspect, the activity route and scope of the target can be tracked and queried among various space-related video surveillance systems through continuous spatial network analysis and buffer analysis. Carry out effective surveillance and capture.

[0016] The following is an example of the arrest and escape by the police, combined with the attached figure 1 The present invention will be described in further detail with specific examples. figure 1 It is a flow chart of the video tracking method based on GIS network analysis and buffer analysis of the present invention. As can be seen from the figure, the video tracking method based on GIS network analysis and buffer analysis acc...

Abstract

The invention relates to the technical field of video monitoring and specifically discloses a video tracking method based on GIS network analysis and buffer area analysis. The method comprises the following steps: S1, establishing a video monitoring network based on geographic information; S2, searching an association point through a GIS network and carrying out video monitoring network analysis on the association point to track the position of a target when finding the target at a video monitoring point in the video monitoring network; S3, carrying out GIS buffer area analysis, establishing a buffer area and carrying out video monitoring network analysis on the video monitoring point in the video monitoring network to track the position of the target when the target suffers from time-and-space fracture or disappears; and S4, forming a continuous position trajectory of the target according to the video monitoring network analysis in S2 and S3. According to the method, spatial continuous tracking on the target is realized by establishing the video monitoring network of a unified coordinate system and making use of GIS spatial network analysis and buffer area analysis.

Description

technical field [0001] The invention relates to the technical field of video monitoring, in particular to a video tracking method based on network analysis and buffer analysis of a Geographic Information System (GIS). Background technique [0002] All kinds of monitoring equipment have become the most common infrastructure in cities, and camera systems are spread all over indoors and outdoors and on various vehicles. Personnel monitoring and searching through the video system is the main way for the public security to arrest and escape. [0003] However, at present, each video surveillance system lacks an effective unified management and information integration mode, which makes it difficult for target surveillance to be carried out among multiple and multi-type camera systems, and it is impossible to realize uninterrupted spatial tracking based on criminal objects. Contents of the invention [0004] In view of the above, the present invention provides a video tracking me...
