Abstract

The invention discloses a four-rotor aircraft indoor security system and method based on visual SLAM. The system includes a four-rotor aircraft, a visual sensor, a wireless transmission module and a ground monitoring station. The image information is collected in real time, and the positioning of the quadrotor aircraft is realized through the visual SLAM positioning method; secondly, the positioning information is transmitted to the controller through Zigbee, so as to control the quadrotor aircraft to patrol and fly according to the specified path; finally, the video is captured in real time through the visual sensor, The captured face information is processed by the on-board microcomputer for face recognition, and the recognition information is transmitted to the ground monitoring station through the wireless transmission module to realize the security function. The invention solves the problem that the quadrotor aircraft cannot be navigated when there is no GPS signal. The quadrotor aircraft in the security system has the characteristics of strong maneuverability, free planning path and no monitoring dead angle, and can realize multi-angle and all-round monitoring.

Description

technical field [0001] The invention relates to the technical field of robot design and control, in particular to a vision SLAM-based indoor security system and method for a quadrotor aircraft. Background technique [0002] In some specific indoor scenes, traditional monitoring equipment has limitations, and there are defects in monitoring dead spots; and some key suspects may be blocked or the suspect will deliberately avoid fixed cameras, which will cause the camera to fail to detect the suspect. the result of. [0003] In 2014, Cong Ji, Wang Lizhong and others disclosed a multi-functional detection security intelligent quadcopter in the paper "Development of a multi-functional detection security intelligent quadcopter" (article number: 1007-9831 (2014) 01-0041-03). The axis aircraft is equipped with an inertial navigation module composed of a three-axis gyroscope and a three-axis acceleration sensor, a wireless data transmission module, etc. on the aircraft, which are us...
