Aerial photographing visible light image processing method and system

Abstract

The invention discloses an aerial photographing visible light image processing method comprising the steps that a visible light image and an infrared image are respectively acquired by simultaneously using a visible light sensor and an infrared sensor; YUV color domain transformation is performed on the visible light image so that a YUV color space image is generated, and the YUV color space image is decomposed into a brightness domain Y component image, a color domain U component image and a color domain V component image; Gaussian low-pass filtering and noise elimination are performed on the brightness domain Y component image obtained through decomposition so as to obtain a brightness domain image; sharpening processing is performed on the infrared image so as to obtain a final sharpening image; the brightness domain image and the final sharpening image are fused so as to generate a final brightness domain Y component image; and hue saturation adjustment is performed on the color domain U component image and the color domain V component image so as to obtain a final color domain U image and a final color domain V image. The technical problems of image edge blurring and detail failure caused by using visible light image noise elimination and enhancement in the present method can be solved by the aerial photographing visible light image processing method and system.

Description

technical field [0001] The invention belongs to the intersection field of digital image processing technology and aerospace science and technology, and more specifically relates to a processing method and system for aerial visible light images. Background technique [0002] Remote sensing and navigation using unmanned aerial vehicles, satellites and other aircraft has become an important technical field in the development of aerospace industry, and has very important application value in economic development and daily life. However, due to the performance constraints of the image sensor on the aircraft, and as the aerial photography scenes become more and more complex and changeable (such as low-light environment, heavy fog, etc.), the aerial images acquired by the aircraft are very noisy and the details are blurred. It cannot meet the needs of remote sensing and navigation fields. Therefore, it is very necessary to process aerial images of aircraft. [0003] At present, th...
