Embodiment 1

[0050] Such as figure 1 As shown, the window opening alarm detection system provided by the embodiment of the present invention includes an image acquisition module 100 , a linkage calibration module 200 , a window calibration module 300 , a window opening detection module 400 and a linkage control module 500 .

[0051]Wherein, the image acquisition module 100 is configured to acquire a monitoring image including a window, and is also configured to acquire a linkage image including the window.

[0052] During specific implementation, the image acquisition module 100 may include a panoramic camera, a linked camera and a pan-tilt camera, for example, a full-color wide-spectrum low-light camera and a point-plane linkage tracking pan-tilt camera. The panoramic camera can be used to obtain the monitoring image including windows in real time, and the linkage image corresponding to any position in the monitoring image can be obtained by adjusting the linkage camera through the pan / ti...

Embodiment 2

[0075] Such as figure 2 As shown, it is a hardware structure diagram of the window opening alarm detection system provided in the second embodiment. The window opening alarm detection system in the second embodiment includes a camera 501 and an integrated processing device 503 connected in communication with the camera. Preferably, the system further includes a network switch 502 .

[0076] The camera 501 is used to acquire monitoring images and linkage images including windows. For example, it can be realized by using a full-color wide-spectrum low-light camera and a point-plane linkage tracking pan-tilt camera. It can be understood that, if necessary, the camera 501 may also include a high-precision turntable and peripheral support structures. The images acquired by the camera 501 are transmitted and summarized to the network switch 502 through the network switch 502 and finally connected to the comprehensive processing device 503 . The image acquisition module 100 can ...

Embodiment 3

[0079] Such as image 3 As shown, it is a flow chart of the window opening alarm detection method provided in the third embodiment, and the method includes the following steps:

[0080] Firstly, in step S1, a monitoring image and a linkage image including windows are obtained.

[0081] Then in step S2, display the monitoring image and the linkage image, and record and obtain the linkage according to the multiple feature point positions marked by the user on the monitoring image and the corresponding sets of pitch angles and horizontal angles of the calibrated linkage cameras location data.

[0082] Then in step S3, a window marking frame corresponding to each window is generated according to at least one window position marked by the user on the monitoring image and preset window parameters.

[0083] Then in step S4, the pixel gray value in the window calibration frame is detected to obtain the detection result of whether to open the window,

[0084] In the final step S5, a...

Abstract

The invention relates to a window opening alarm detection system and method, the system comprising: an image acquisition module, a linkage calibration module, a window calibration module, a window detection module and a linkage control module; the window calibration module is used to generate a window corresponding to each window The window calibration frame; the window detection module is used to detect the pixel gray value in the window calibration frame to obtain the detection result of whether the window is opened; the linkage control module is used to calculate the pitch angle and the horizontal angle of the linkage camera, The linked camera is adjusted to display a linked image corresponding to the window calibration frame in which the window is detected. Based on the window calibration frame, the present invention can realize rapid detection of small changes of windows on the facade of a building, and obtain clear and detailed information of the observation target through the linkage image displayed by the linkage control module.

Description

technical field [0001] The invention relates to the technical field of computer image processing and detection, in particular to a window opening alarm detection system and method. Background technique [0002] At present, the security on-site monitoring of large-scale activities presents the characteristics of many monitoring points, wide distribution, and complex exchanges between multiple security units and mobile personnel on the site. Traditional large-scale activities are to prevent terrorists or criminals from delivering dangerous items or sniping from the facade windows of buildings. Important people often use hand-held binoculars to monitor. Long-term and boring monitoring not only requires a lot of police resources, but also relies heavily on the on-site mental state and handling experience of security personnel, resulting in a large actual investment of resources and poor security effects. result. In addition, the monitoring image in the existing security system ...
