Method and system for sensing motion gestures of moving body

Abstract

The invention discloses a method and a system for sensing motion gestures of a moving body. The method and the system are mainly designed for comprehensively and efficiently sensing all the information of the motion gestures of the moving body. The method comprises the following steps of: continuously capturing images of a reference surface when the moving body is in a moving state; calculating light stream information in the images according to the captured continuous images; and obtaining the motion gestures of the moving body based on the calculated light stream information. The system and the method can sense all the information of the motion gestures of the moving body, and can provide more comprehensive and efficient motion gesture information for flight attitude monitoring and control on airplanes, earth surface and terrain measurement, and motion gesture monitoring on other objects like jigs or cutters.

Description

technical field [0001] The invention relates to the fields of optics, electronic information and aviation, in particular to a motion posture perception method and system of a moving body. Background technique [0002] Aircraft flight attitude refers to the degree of pitch, roll and yaw during the flight of the aircraft. The standard to measure the flight attitude of the aircraft is the aircraft attitude angle, including: pitch angle, roll angle and yaw angle. In order to ensure the normal flight of the aircraft, it is necessary to measure and control the flight attitude of the aircraft. [0003] The aircraft attitude perception system is an important part of the aircraft attitude control system, which provides feedback for the aircraft attitude closed-loop control. In the prior art, aircraft mostly use devices such as accelerometers, gyroscopes, and infrared horizons for attitude measurement. However, for small and micro unmanned aircraft, the above-mentioned technologies ...

Problems solved by technology

For example, the one-dimensional optical flow information aircraft attitude perception and control system made by Ecole Polytechnique Federale de Lausanne (EPFL) in Switzerland, but this system cannot obtain all information of the aircraft attitude, that is, pitch, roll, yaw angle and angular velocity. Can obtain yaw angle and angular velocity, this system is mainly used for obstacle avoidance and navigation, only suitable for low-speed miniature indoor drones
