Embodiment

[0022] A kind of unmanned aerial vehicle detection image registration method of the present invention comprises Harris corner point algorithm and image registration flow process, also comprises the following steps:

[0023] S1. Obtain the video information obtained by the drone, collect sample images through the camera at a rate of 10-30 images per hour, and then select an optimal image in each sampling interval to form a configuration according to the parameters of definition and noise. quasi-image set, and the remaining images are used as source images for testing;

[0024] S2, perform the same preprocessing on the source image and the registered image, and use basic statistical features to perform preliminary image rotation, translation, and scale transformation to remove redundant noise;

[0025] S3, using the Harris corner algorithm to perform Harris corner detection on the source image and the registration image, and record the corner coordinates;

[0026] S4, take the ...

Abstract

The invention discloses an unmanned aerial vehicle detection image registration method, and relates to an unmanned aerial vehicle detection image registration method, comprising a Harris corner algorithm and an image registration process, and further comprising the following steps: S1, acquiring video information acquired by an unmanned aerial vehicle, and setting a source image set and a registration image set; S2, carrying out the same preprocessing of the source image and the registered image, carrying out the preliminary image rotation, translation and scale transformation through the basic statistical features, and removing the redundant noise; S3, performing Harris corner detection on the source image and the registration image by using a Harris corner algorithm, and recording cornercoordinates; S4, setting a registration area; S5, calculating a correlation coefficient of a registration area of the source image and the registration image; S6, judging the matching degree of the source image and the registration image by using the correlation coefficient; and S7, entering an image registration process. According to the unmanned aerial vehicle detection image registration method, the problem of unmanned aerial vehicle video frame image registration can be effectively solved, and an ideal registration image set is obtained; and the unmanned aerial vehicle detection image registration method has good feature invariance, uniqueness, stability and independence.

Description

technical field [0001] The invention relates to a registration method for an unmanned aerial vehicle detection image, in particular to a registration method for an unmanned aerial vehicle detection image. Background technique [0002] Image registration is the process of superimposing two or more images of the same scene obtained by different time, different viewing angles, and different sensors. At present, there is a problem that the video images acquired by drones cannot have an effective image registration scheme. Contents of the invention [0003] The technical problem to be solved by the present invention is that currently there is a problem that video images acquired by drones cannot have an effective image registration scheme, and the purpose is to provide a method for image registration of drone detection to solve the above problems. [0004] The present invention realizes through following technical scheme: [0005] A kind of unmanned aerial vehicle detection i...
