Problems solved by technology

[0002] In related technologies, high-altitude parabolic phenomenon is an important hidden danger to the safety of residential areas. High-altitude parabolic objects not only pollute the urban environment, but also pose a threat to the lives and property of people on the ground.
[0003] When the relevant technology detects high-altitude parabolas, it usually uses multiple camera modules for continuous detection, and judges and traces through human eyes. It is often very difficult to locate this scene in hours of video, and some high-altitude parabolic behaviors have occurred but did not cause harm, and cannot be detected, prevented and warned in time
[0004] For the above-mentioned problems existing in related technologies, no effective solution has been found yet

Abstract

The invention discloses a method and device for judging a high-altitude parabolic object, and the method comprises the steps: obtaining an original image frame at a first time, the original image frame comprises a building background region, and the building background region is a monitoring region of the high-altitude parabolic object; determining a candidate parabolic object according to the original image frame; obtaining an associated image frame of the original image frame at a second time, and calculating operation parameters of the candidate parabolic object according to the original image frame and the associated image frame, the second time being adjacent to the first time; and determining that the candidate parabolic object is a high-altitude parabolic object according to the operation parameters. Through the method and the device, the technical problem of low efficiency caused by video recognition of the high-altitude parabolic object in related technologies is solved, accurate recognition and judgment of the high-altitude parabolic object are realized, accurate tracing and early warning of the high-altitude parabolic object are further realized, and the monitoring efficiency of the high-altitude parabolic object is also improved.

Description

technical field [0001] The invention relates to the field of computers, and more specifically, to a method and device for judging a high-altitude parabola. Background technique [0002] In related technologies, the high-altitude parabolic phenomenon is an important hidden danger to the safety of the community. The high-altitude parabolic not only pollutes the urban environment, but also poses a threat to the lives and property of people on the ground. [0003] When the relevant technology detects high-altitude parabolas, it usually uses multiple camera modules for continuous detection, and judges and traces through human eyes. It is often very difficult to locate this scene in hours of video, and some high-altitude parabolic behaviors have occurred but have not caused harm, and cannot be detected, stopped and given early warning in time. [0004] Aiming at the above-mentioned problems existing in related technologies, no effective solution has been found yet. Contents of ...
