Problems solved by technology

[0004] However, such a monitoring method not only consumes a lot of labor costs, but also negative factors such as fatigue and environmental noise can easily lead to people's distraction, which poses a large safety hazard. After a throwing or falling object occurs, manual review Then there is greater passivity and hysteresis, unable to respond quickly to high-altitude parabolic behavior

Embodiment 1

[0031] Figure 1A It is a flow chart of a method for identifying a falling object provided by Embodiment 1 of the present invention. This embodiment is applicable to monitoring whether there is a falling object in a surveillance video. recognition device, which can be implemented by software and / or hardware, and integrated in the monitoring camera component or a management control device (for example, server, edge computing device) connected to the monitoring camera component, the method specifically includes the following steps:

[0032] S110. Obtain the video image frame of the surveillance video, and perform background difference with the background image frame to obtain a plurality of binarized marked image frames, and obtain the moving track image frame of the motion area according to each of the binarized marked image frames .

[0033] Surveillance video can be obtained through surveillance camera components installed in front of buildings, such as Figure 1B As shown, ...

Embodiment 2

[0049] figure 2 It is a flow chart of a falling object recognition method provided by Embodiment 2 of the present invention. This embodiment is embodied on the basis of the above embodiments. In this embodiment, when each binarization within the preset detection time When the marked image frames all include motion areas, it is judged that there is a suspicious falling object in the surveillance video, and then the image classification model is used to further determine whether it is a falling object. The method specifically includes:

[0050] S210. Acquire a video image frame of the surveillance video, and perform background difference with the background image frame to obtain a plurality of binarized marked image frames.

[0051] S220. If it is determined that each of the binarized marked image frames within the preset detection time includes a motion area, then determine the first binarized marked image frame within the preset detection time as the motion start frame, and ...

Embodiment 3

[0061] image 3 It is a structural block diagram of a device for identifying a falling object provided in Embodiment 3 of the present invention, and the device specifically includes: a moving trajectory acquisition module 310, a trajectory classification execution module 320, and a falling object determination module 330;

[0062] The movement trajectory acquisition module 310 is used to acquire video image frames of the surveillance video, and perform background difference with the background image frames to obtain a plurality of binarized marked image frames, and obtain motion The moving track image frame of the region;

[0063] The track classification execution module 320 is used to input the moving track image frame of the moving area into the trained image classification model, so as to judge whether the moving track of the moving area is a falling object track through the image classification model;

[0064] The falling object determination module 330 is configured to ...

Abstract

The embodiment of the invention discloses a falling object identification method and device, equipment and a storage medium, and the method comprises the steps: carrying out the background differenceof a video image frame and a background image frame of a monitoring video, so as to obtain a plurality of binarization mark image frames, and obtaining a movement track image frame of a movement region according to each binarization mark image frame; inputting the moving track image frame of the moving area into a trained image classification model, so as to judge whether the moving track of the moving area is a falling object track or not through the image classification model; and if it is determined that the moving track of the moving area is a falling object track, determining that a falling object exists in the monitoring video. According to the technical scheme provided by the embodiment of the invention, the falling object in the monitoring video is effectively monitored, the monitoring efficiency and the monitoring timeliness of the falling object are greatly improved, meanwhile, the false alarm detection rate of the falling object in the monitoring video is reduced, and the recognition mode has relatively high robustness and universal applicability.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of monitoring, and in particular, to a method, device, terminal device, and storage medium for identifying a falling object. Background technique [0002] The continuous advancement of science and technology has made video surveillance technology widely used in social life. With more and more high-rise buildings rising on the ground, the effective monitoring of high-altitude falling objects has become an important technical means to ensure the safety of social life. [0003] In the existing monitoring scheme for high-altitude falling objects, by arranging cameras outside the building, real-time video recording is performed on the outer wall of the building, and the staff manually observes the front of the monitoring screen to monitor the behavior of high-altitude throwing objects. However, after the parabolic or falling behavior occurs, the relevant units such as the property or the...
