Problems solved by technology

At present, the existing IVS systems (such as the IVS system of ObjectVideo in the United States, the IVS system of Beijing Wen'an in China, etc.) all analyze and process the video data and directly output the relevant alarm event information. In this way, when using different event rules to define When making a judgment, it is necessary to reload the video data, and then analyze and process the video data, which is inefficient
In addition, when browsing and querying alarm events, the current IVS system generally provides text (time, camera position information, etc.) positioning function

Embodiment Construction

[0036] The features and advantages of the present invention will be described in detail with reference to the accompanying drawings.

[0037] The event retrieval method in this embodiment is aimed at events that usually need to be given an alarm during video surveillance. Please refer to figure 1 , the video monitoring event retrieval method is implemented according to the following flow.

[0038] Step 1. Define event rules

[0039] Before retrieving the alarm event corresponding to the information flow of the moving target, define the alarm event rules first. Use the saved surveillance video to define alarm event rules according to its video file screen. Alarm event rules include: access control detection, traffic flow detection, area intrusion detection, area wandering detection (parking violations), reverse detection, cross-border detection, leftover detection and luggage loss detection. Each alarm event rule specifies the relevant condition parameter threshold. Event ...

Abstract

The invention discloses a intelligent video monitor search method, including the steps: collecting the video frame, extracting the moving target information flow, storing the corresponding moving target information flow of the video frame; searching the stored moving target information flow, judging the detected object whether matching with the defined affair rule, if so, determining the corresponding occurrence of the affair rule. Furthermore, the invention includes the step of inquiring the stored affair and the step of playing back the corresponding video frame based on the affair selection. The invention discloses an intelligent video monitor affair search system for executing the method. Due to the target information data flow smaller than the video data flow, hence the invention has faster searching speed, higher searching effectiveness, higher data transmission, lower cost compared with the prior scheme.

Description

【Technical field】 [0001] The invention relates to the field of video surveillance, in particular to an intelligent video surveillance (Intelligent Video Surveillance, IVS) event retrieval method and system. 【Background technique】 [0002] The basic principle of Intelligent Video Surveillance (IVS) is to use computer vision technology to analyze, process and apply video images. The realization of IVS generally includes the following levels: [0003] 1) Moving target extraction [0004] 2) Moving target tracking [0005] 3) Target recognition [0006] 4) Behavior analysis [0007] The result of IVS behavior analysis is the alarm event, and the alarm event is also the function that the user finally needs to realize. After analyzing the target behavior, judge whether the analysis result matches the defined alarm event rules. Since different alarm event rules correspond to different alarm events, it can also be determined whether an alarm event occurs. At present, the exist...
