Problems solved by technology

Use the traditional image registration method based on image content to extract small targets. When the background is a scene without obvious texture features such as deserts, seas, fields, and grasslands, there are no feature point pairs that can be extracted, resulting in the inability to carry out registration work.

Embodiment Construction

[0035] The airborne infrared moving target detection method based on geographic homonym registration provided by the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0036] The airborne infrared moving target detection method based on geographic homonym registration provided by the present invention includes the following steps in order:

[0037] 1. Map the image plane imaging point to the ground target point

[0038] For any target T in the task load observation scene, it is assumed that the task load camera coordinate system coincides with the image plane coordinate system, and the center position of the task load camera image plane is the flying height of the aircraft; the origin of the earth coordinate system is (0,0,H), The imaging focal length of the task load is f, the azimuth angle of the task load is θ, and the pitch angle of the task load relative to the aircraft platform is α; The imaging ...

Abstract

An airborne infrared moving target detection method based on geographical homologous point registration comprises the following steps: mapping an image plane imaging point to a ground target point; performing region registration on a reference image and a to-be-matched image; compensating the motion of the reference image and the to-be-matched image to get motion-compensated images; performing inter-frame difference operation on the motion-compensated reference image and the motion-compensated to-be-matched image to get a suspected moving target; and reversely verifying the motion features of a suspected moving region to get a final moving target detection result. The method involves a small amount of calculation, and takes less time. The hardware delay time and the software processing burden are greatly reduced. The detection efficiency of the system is improved.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition, and in particular relates to an airborne infrared photoelectric moving target detection method based on geographical homonym registration. Background technique [0002] In the infrared photoelectric system under the condition of the aircraft moving carrier, due to the complex scene conditions, the target features are not obvious, so in this application, the detection of weak and small moving targets is a major difficulty in the field of automatic target detection. Using the traditional image registration method based on image content to extract small targets, when the background is desert, sea, field, grassland and other scenes without obvious texture features, there are no feature point pairs that can be extracted, resulting in the inability to carry out registration work. Contents of the invention [0003] In order to solve the above problems, the object of the present invention i...
