Embodiment 1

[0055] An embodiment of the present invention, such as figure 1 As shown, the present invention provides a method for real-time detection of regional intrusion, comprising steps:

[0056] S1. Receive and display a monitoring picture captured by a monitoring device.

[0057] Specifically, in practical applications, when installing the monitoring camera of the video monitoring equipment, it is best to adopt a top-down installation to avoid the situation that the target is blocked by the background or the target is separated from the background.

[0058] S2. Draw several areas on the display interface as target detection areas.

[0059] When drawing the target detection area, draw one or more polygons as the target detection area according to the proportion of the actual scene, which is convenient for overlapping areas. Of course, you can also draw circles, ellipses, irregular shapes and other shapes as the target detection area.

[0060] S3. Perform target detection on the fra...

Embodiment 2

[0072] An embodiment of the present invention, such as image 3 As shown, on the basis of Embodiment 1, before performing target detection on the frame image of the monitoring screen, it also includes: preset reliability. Specifically, the range of the confidence level is between 0 and 1, which is specifically adjusted according to the detection accuracy.

[0073] When the overlapping area reaches the preset threshold, an intrusion alarm will be issued, including: when S 重 / S 总 >(1-d), an intrusion alarm is issued, where, S 重 is the overlapping area, S 总 is the total area of ​​the bounding rectangle of the target, and d is the preset confidence level. Through this formula, the calculation can be performed according to the actual situation of the target, making the intrusion judgment more reasonable.

[0074] Preferably, after calculating the overlapping area between the bounding rectangle of the target and the target detection area, it further includes: when the overlappi...

Embodiment 3

[0078] An embodiment of the present invention, such as Figure 4 As shown, the present invention also provides an area intrusion real-time detection system, including a monitoring device 1 and a computing terminal 2 . In this embodiment, the computing terminal 2 is a computer-based client system, which is convenient for screen display and operation control. In other embodiments, other similar terminals can also be selected.

[0079] The monitoring device 1 is used to shoot monitoring images; the computing terminal 2 is connected to the monitoring device 1 for receiving and displaying the monitoring images sent by the monitoring device 1 .

[0080] Wherein, the computing terminal 2 includes an input module 21 , a detection module 22 , a tracking module 23 , a computing module 24 and an alarm module 25 .

[0081] The input module 21 is used to draw several areas on the display interface as target detection areas; the detection module 22 is used to perform target detection on th...

Abstract

The invention provides a regional intrusion real-time detection method and system and a storage medium. The method comprises the following steps: receiving and displaying a monitoring picture shot by monitoring equipment; drawing a plurality of areas in the display interface as target detection areas; performing target detection on the frame image of the monitoring picture, and drawing a boundary rectangular frame for each detected target; tracking the detected target in real time, and for the target appearing in any target detection area, calculating an overlapping area of a boundary rectangular frame of the target and the target detection area; and when the overlapping area reaches a preset threshold value, performing intrusion alarm. The scheme can be suitable for a single target or multiple targets, can avoid mutual influence among the targets, is beneficial for improving intrusion judgment precision, and avoid the situation that intrusion response is not timely or intrusion misjudgment occurs.

Description

technical field [0001] The invention relates to the technical field of intrusion detection, in particular to an area intrusion real-time detection method, system and storage medium. Background technique [0002] Intelligent monitoring is an embedded video server that integrates intelligent behavior recognition algorithms, which can identify and judge the behavior of pedestrians or vehicles in the screen scene, and generate alarms to remind users under appropriate conditions. Video surveillance is to monitor, record, and backtrack the video image by obtaining the video image information of the monitoring target, and make corresponding actions manually or automatically according to the video image information, so as to achieve the monitoring, control, security and security of the monitoring target. Intelligent management has been widely used in many public places such as fire protection, forestry, dams, airports, railways, ports, urban transportation, etc., and with the advanc...
