Embodiment 2

[0107] Example 2: For civil high-altitude parabolic detection equipment, a balance needs to be struck between the detection effect and the hardware cost: our improved detection method based on computer vision can better collect evidence at the initial stage of the high-altitude parabolic occurrence process, and the price low. High-altitude parabolic detection based on radio analysis can detect high-speed falling objects at the end of the high-altitude parabola, but the sensor is relatively expensive. Combining methods based on computer vision and radio analysis can certainly achieve better results than either method. But if we consider the cost factor, we can choose a single method based on computer vision in the actual implementation process.

[0108] Among them, a surveillance camera is also arranged to monitor the lens of high-altitude throwing objects.

[0109] The beneficial effects of the present invention are as follows:

[0110] 1. Compared with the existing schemes...

Abstract

The invention discloses a high-altitude parabolic detection method based on computer vision and radio signal analysis, including a method based on computer vision and a method based on radio signal analysis; the method based on computer vision includes Modular motion detection method, motion detection algorithm based on background modeling, adaptive OTSU threshold calculation method, self-created high-speed tracking algorithm. The present invention can capture the time and position of the high-altitude parabola by means of computer vision and radio analysis; this scheme adopts the combination of real-time analysis and video recording, can more accurately locate the time and position of the high-altitude parabola, and obtain evidence accurately; avoid camera capture Delay; at the same time, computer vision and radio signals are used to analyze high-altitude parabolic objects more accurately and reduce the number of false alarms; our plan also arranges surveillance cameras to monitor high-altitude projectiles to prevent high-altitude parabolic objects from being moved and picked up by people, making the evidence destroy.

Description

technical field [0001] The invention belongs to the field of intelligent video monitoring, and in particular relates to a method for detecting high-altitude parabolic objects based on computer vision and radio signal analysis. Background technique [0002] High-altitude parabolic can cause serious consequences of personal injury and heavy property loss. [0003] At present, there are two commonly used methods for high-altitude parabolas: [0004] Existing technical scheme one: [0005] Generally, after a high-altitude parabola has occurred in the community, causing casualties or property damage, the management personnel will transfer video recordings for passive evidence collection. This method requires people to watch the video to determine the time and location of the high-altitude parabolic occurrence. It is easy because of Personnel-generated factors lead to misjudgment. Simultaneously, the high-altitude parabolic incidents that do not cause casualties or property los...
