A flight system feedback control method, device, equipment and storage medium

Abstract

This invention relates to the field of image detection technology, and discloses a flight system feedback control method, device, equipment, and storage medium. The method includes: extracting features from a visual image based on a preset maximum absolute gradient evaluation function to obtain a sharpness sequence; analyzing the sharpness sequence according to a preset offline calibration inverse function and a preset adaptive threshold rule to obtain a defocus sequence and adaptive analysis results; performing compliance analysis on the defocus sequence based on the adaptive analysis results and a preset focusing time upper limit to obtain compliance analysis results; and generating a flight feedback control signal based on system matrix parameters, system state, feedforward commands, and compliance analysis results. By efficiently extracting the image sharpness sequence, combining offline calibration and adaptive thresholding to quickly adapt to complex scenarios, and relying on the focusing time upper limit to avoid noise misjudgment, a flight feedback control signal is finally generated, effectively improving the focusing response speed under high-speed flight conditions.
