Eagle eye midbrain loop return inhibition mechanism-imitated unmanned target drone target detection method

Abstract

The invention discloses an eagle eye midbrain loop return inhibition mechanism-imitated unmanned target drone target detection method, which comprises the following steps of: 1, calibrating a camera,acquiring internal and external parameters of the camera, and correcting image distortion; 2, carrying out the illumination processing of imitating the color constancy of the beasts, and recovering the color information of the image under the normal illumination; 3, preprocessing an eagle midbrain opening and closing corresponding mechanism-imitated image; 4, extracting a salient region based on an eagle visual sensitivity function; and step 5, carrying out target output based on an eagle brain return inhibition mechanism. The method has the advantages that 1, an eagle eye biological image processing mechanism is used for reference, and an eagle midbrain loop return inhibition target detection framework is extracted and applied to small target detection of an unmanned target drone; 2, themethod can adapt to the small target detection problem of the target drone in various environments, the influence of external factors such as illumination and contrast is eliminated, and the algorithmadaptability is improved; and 3, the method is simple in framework, the target detection calculation amount is saved, and the airborne calculation load requirement is greatly reduced.
