High-altitude object throwing detection method based on computer vision and radio signal analysis

The invention discloses a high-altitude object throwing detection method based on computer vision and radio signal analysis. The detection method comprises a computer-vision-based method and a radio-signal-analysis-based method. The computer-vision-based method includes a background-modeling-based mobile detection method, a background-modeling-based mobile detection algorithm, an adaptive OTSU threshold calculation method, and a self-made high-speed tracking algorithm. According to the invention, the high-altitude object throwing time and location can be captured by means of computer vision and radio analysis. On the basis of combination of real-time analysis with video recording, the high-altitude object throwing time and location can be located accurately and thus evidences are taken accurately; and the capturing delay of the camera is avoided. Meanwhile, the high-altitude object throwing can be detected precisely by using the computer vision and radio signal analysis; and the false reporting number is redu
