A fully automated micro quadrotor autonomous landing and charging method and system

Abstract

The invention belongs to the technical field of information processing and control, and discloses a method and system for automatic landing and charging of a miniature quadrotor. The method for automatic landing and charging of a miniature quadrotor includes: early warning of electric power of a miniature quadrotor , use GPS to locate the micro quadrotor and fly directly above the ground relay station; the camera shoots the micro quadrotor, performs background difference, locates, captures, and tracks the micro quadrotor; combined with the differential GPS information sent back from the micro quadrotor and the ground, Read the height of the micro-quadrotor, perform 3D positioning, and guide the micro-quadrotor to land autonomously. The invention can automatically control the take-off and landing of the miniature quadrotor, which saves manpower. At the same time, the opening and closing device and the frame can ensure that the miniature quadrotor will not be damaged in special weather. The takeoff and landing of the existing domestic drones are mostly completed on the ground. , there is no fixed liftable opening and closing structure to ensure the preservation and smooth take-off of the drone.

Description

technical field [0001] The invention belongs to the technical field of information processing and control, and in particular relates to a method and system for automatic landing and charging of a miniature four-rotor. Background technique [0002] At this stage, there are two major limitations of micro quadrotors: short battery life and high additional labor costs, which fundamentally limit the large-scale use and application fields of micro quadrotors. If the micro-quadrotor can independently find the nearest ground relay station for wireless charging when the battery is in the early warning, and automatically return to the flight line after the charging is completed, and continue to carry out unattended operations, the entire process can be fully automated. In order for the micro-quadrotor to complete wireless charging autonomously, it is necessary to complete the outdoor autonomous landing of the micro-quadrotor. Most commercial drones on the market use GPS for positioni...

Problems solved by technology

[0003] To sum up, the problems existing in the existing technology are: the system composition of the first technology is cumbersome and complicated, and it has a high dependence on the hardware configuration of the UAV, which leads to the high overall cost of the UAV and is difficult to popularize; the second technology is now There are high requirements for the computing power of the UAV system and high power consumption, resulting in a decrease in the endurance of the UAV, which restricts its flight distance and limits the application field
