AI Technical Summary

Technical Problem

In the current technology for controlling the landing of rotary-wing UAVs in complex water environments, the calculation of the vision-thrust response gain ignores the influence of visual environmental entropy on confidence and the limitation of residual energy on maneuverability. This makes the control system susceptible to interference from false edge features, resulting in high-frequency invalid oscillations and energy dissipation, which affects the accuracy and safety of the landing process.

Method used

An environmental perception acquisition module is used to acquire image data and energy status. A visual confidence index is calculated through a visual entropy calculation module. A visual-thrust response gain is established in combination with a dynamic gain adaptation module to dynamically adjust the sensitivity of the control system. When the confidence level or energy is low, the system switches to a low-gain mode. Low-pass filtering and an edge computing gateway are introduced to optimize data transmission.

Benefits of technology

It improves the stability and energy efficiency of the control system in complex water environments, avoids interference from false edge features and energy dissipation, and ensures the survivability and precise landing capability of UAVs under extreme conditions.

Abstract

The invention relates to the technical field of unmanned aerial vehicle control and computer vision, in particular to a rotor unmanned aerial vehicle landing auxiliary system for ship object recognition and visual detection, which comprises an environment perception acquisition module for acquiring a landing area image and normalized residual energy data in real time; the visual entropy resolving module is used for extracting texture features, calculating visual environment entropy and generating a visual confidence index; the dynamic gain adaptation module is used for establishing a dynamic mapping relation between confidence and an energy state and adaptively resolving a vision-thrust response gain; the flight execution control module is used for generating an attitude and thrust control instruction based on gains, and driving a descending action by adopting a basic feed-forward combined visual correction framework; the method effectively solves the contradiction between energy dissipation and visual precision in a complex water surface environment, and ensures that the unmanned aerial vehicle can still maintain the basic flight ability in a low-confidence state.
