Time-division retrieval method of surveillance video information with PTZ control based on spatio-temporal characteristics

Abstract

The present invention disclosed a method for retrieved the method of monitoring video information controlled by the space -time characteristics. This method has a preset video information in the video surveillance system.The video information is stored according to the preset bit and the output is displayed by the independent window, which can also be displayed on the preset position of the continuous cruise video file; when the video storage is performed, it can be stored according to the number of presets.This video file only stores the video information of the corresponding preset bit; when the output is displayed, create the corresponding display window for each preset position. Each window only displays the corresponding video of the preset position.The spatial attribute of the preset position is distributed in different positions of the screen, which intuitively reflects the space -time characteristics of the monitoring area.The present invention solves the problem of rapid retrieval of the traditional video surveillance system for the rapid retrieval of video surveillance information controlled by Yundai.

Description

technical field [0001] The invention relates to video information retrieval technology in the technical field of video monitoring, in particular to a method for retrieving and storing video information obtained by a camera controlled by a pan-tilt. Background technique [0002] Video security monitoring systems have been deployed in large numbers in the society, and play a vital role in case detection and social security maintenance in the public security field. With the construction of large security projects such as "Skynet Project" and "Safe City", and With the wide application of various video surveillance equipment in the society, it has become a reality to use video images to serve for case investigation, and has shown excellent performance. [0003] Behind the excellent record of video reconnaissance, there is the wisdom of the scouts, but also the hardships of a large number of video monitors to check the video information. With the deployment of a large number of v...

Problems solved by technology

When the video monitor checks the video information with the PTZ preset position cruise, because the video screen is constantly switching at each preset position, the video information for determining the direction of the PTZ cannot be directly retrieved. When the video monitor finds the key target It will not be able to concentrate well, which will not only reduce the efficiency of video viewing, but also increase the chance of inadvertently missing key targets and missing the opportunity to solve the case

Therefore, although there is a surveillance camera controlled by the pan / tilt, in the case of cruise in the preset position, a larger spatial range is monitored, and it also brings inconvenience to the video surveillance personnel to view video information and case investigation
