AI Technical Summary

Problems solved by technology

This positioning method can obtain higher positioning accuracy, but this positioning method cannot be used in indoor environments where the GPS signal is poor or there is no signal.
It may even fly out of the control range and cause loss of control, or crash into an obstacle due to drift

Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] It should be noted that when a component is said to be "fixed" to another component, it can be directly on the other component or there can also be an intervening component. When a component is said to be "connected" to another component, it may be directly connected to the other component or there may be intervening components at the same time. When a component is said to be "set on" another component, it may be set directly on the other component or t...

Abstract

The present invention relates to the technical field of unmanned aerial vehicles, in particular to a quadrotor aircraft system based on optical positioning, which includes an aircraft body and a control module. The control module includes a coordinate system module, a motion module, an application module, a self-stabilization module and a main control module. module, the motion module is used to control the movement of the aircraft body; the application module includes a fixed height sub-module, a fixed point sub-module and an obstacle avoidance sub-module, and the fixed height sub-module is used to make the aircraft body close to the height of the target position, The fixed-point sub-module is used to make the aircraft body close to the horizontal position of the target through the optical flow sensor and the fixed-focus lens. The obstacle avoidance sub-module is used for the aircraft body to avoid obstacles; The flight attitude is adjusted during take-off; the main control module is used for data algorithm processing of each module. The invention enables the aircraft to locate and prevent drift without GPS signals.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to a quadrotor aircraft system based on optical positioning. Background technique [0002] Quadrotor aircraft is an unmanned aerial vehicle that has gradually become popular in recent years. It has been popularized due to its special flying mode and low mechanical failure rate. Especially in the fields of aerial photography and agricultural plant protection, more and more new functions and uses have been discovered as a stable flying platform, and the requirements for its performance have gradually become higher, especially for aircraft that can precise positioning requirements. [0003] Multi-rotor aircraft generally adopt GPS positioning, and the longitude and latitude coordinates are obtained by receiving satellite signals through the GPS module to maintain the flight coordinates in space. Such a positioning method can obtain high positioning accuracy, but such...
