| description | The invention relates to a person falling detection method and system based on an unmanned aerial vehicle. The method comprises the following steps that the unmanned aerial vehicle is controlled to fly; acquiring a ground image in real time through imaging equipment carried on an unmanned aerial vehicle holder, and performing human body recognition according to the ground image; if the ground image contains the human body, acquiring key points of the human body, and determining the pixel width and height of the human body in the image according to the key points; obtaining the area S0 occupied by the human body in the image according to the pixel width and height of the human body in the image, and obtaining the latitude and longitude of the position of the human body according to the flight control data of the unmanned aerial vehicle; comparing the area occupied by the human body in the image with a preset area threshold value; and the unmanned aerial vehicle sends the image of the tumble person and the lati |
