A kind of flying umbrella and control method

Abstract

The application discloses a flying parachute and a control method. The flying parachute includes a flight control unit, an umbrella surface, a rotor, and a camera; the flight control unit is used to control the rotor; the rotor is placed above the umbrella surface; The center below the umbrella surface; the vertical line at the center of the umbrella surface is on the pitch plane of the camera. The embodiment of the present application provides a parachute control method, the camera captures the image of the human body, and extracts the shoulder width and height monitoring values; when the difference between the width monitoring value and the standard width value exceeds the first predetermined range, the flight control unit Controlling the paraglider to move in the air; capturing the image of the human body again, and extracting the monitoring value of shoulder width until the difference between the monitoring value of the width and the standard width value is within a first predetermined range. The invention can make the positioning error between the parachute and the person reach centimeter level, and the parachute can track the action of the person in real time.

Description

technical field [0001] The present application relates to the technical field of unmanned aerial vehicles, in particular to an unmanned aerial vehicle with a parachute and a control method thereof. Background technique [0002] UAV technology is developing rapidly, and its power system, flight control system and other technologies are becoming more and more mature, which can realize hovering and level flight; face recognition technology is also developing rapidly, and technologies such as face and human body monitoring, identification, and tracking have reached practical level, and can be implemented on embedded processors. UAVs that combine the two to achieve follow-up shooting have also appeared, such as DJI and hover drones. There are also attempts to use UAV technology for parasols, such as a UAV parasol proposed by CN201610993395, which uses the principle of differential GPS to track pedestrians by UAVs. However, the positioning accuracy of differential GPS is relativ...
