Time division searching method based on time-space characteristics for monitoring video information with pan-tilt control

Abstract

The invention discloses a time division searching method based on time-space characteristics for monitoring video information with pan-tilt control. According to the method, video information with presetting bit cruising in a video monitoring system can be respectively stored, displayed and output through independent windows according to presetting bits and cruising interval time, and continuous cruising video files can also be displayed and output according to the presetting bits; when video storage is carried out, video files corresponding to the presetting bits in number are established and stored according to the number of the presetting bits, and each video file only stores video information corresponding to the corresponding video file; when displaying and output are carried out, corresponding display windows are set up for the presetting bits, each window only displays a video of the corresponding presetting bit, the display windows corresponding to the presetting bits are distributed at different positions of a screen according to spatial attributes of the presetting bits, and time-space characteristics of a monitoring area are visually embodied. The method solves the problem that a traditional video monitoring system is difficult in quick searching of the video monitoring information with pan-tilt control.

Description

Technical field [0001] The present invention relates to video information retrieval technology in the field of video surveillance technology, in particular to a retrieval and storage method for 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. They play a vital role in case detection and social security maintenance in the public security field. With the construction of large-scale security projects such as "Skynet Project" and "Safe City", and The wide application of various video surveillance equipment in the society, the use of video images for case investigation services has become a reality and has shown excellent performance. [0003] Behind the excellent record of video surveillance is the wisdom of the investigators, as well as the hardship of a large number of video monitors viewing video information. With the deployment of a large number of vi...

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
