Embodiment Construction

[0031] The present invention will be described in further detail below according to the drawings and embodiments.

[0032] Such as figure 1 , figure 2 As shown, the present invention mainly includes an image generation module, an image acquisition module, an image fusion processing module, and an image evaluation module, and the implementation process is as follows:

[0033] 1. Image generation module: Use two computers to simulate the generated visible light and infrared images by software. Under laboratory conditions, infrared images and visible light images of the same scene, clear, fog, rain, snow, night, day, and towns, grasslands, deserts, etc. at different times, different climates, and different backgrounds can be obtained. This module is only used in experimental situations. For example, in the actual scene, two sensors collect infrared images and visible light images respectively.

[0034] 2. Image acquisition module: Use 2 DVI image acquisition cards to collect...

Abstract

The invention discloses a video image fusion-processing system. The video image fusion-processing system comprises an image acquiring module, an image fusion-processing module, an image evaluating module, wherein the image acquiring module is used for realizing format conversion between infrared image and visible light which are acquired by two coaxial sensors in real time; the image fusion-processing module is used for performing frame-by-frame processing on the format-converted infrared image and visible light image; if the infrared image is not matched with the visible light image, performing image rectification and then performing fusion-processing to obtain a fused image; the image evaluating module is used for calculating various image indexes before and after fusing, and analyzing the fused results. Through the fused images, the video image fusion-processing system can be used for obtaining a certain strengthening effect under a greasy weather condition or a night condition.

Description

technical field [0001] The invention relates to the field of digital image processing in aerospace, and relates to a realization method for simulating aerial images under ground conditions and performing real-time processing. technical background [0002] In the military field, target detection technology is a key technology in the reconnaissance defense system. For example, the tracking and identification of moving targets by the defense system, missile guidance, target detection and targeting of various weapon systems, etc., can greatly improve the combat performance of the weapon system. Various aircraft such as unmanned aerial vehicles, helicopters, combat aircraft, etc. also rely on many advanced optoelectronic devices, such as high-definition forward-looking infrared sensors, high-resolution and high-magnification CCD sensors, etc. to perform various tasks. Photoelectric detection equipment has the advantages of fast real-time performance, low power consumption, and l...
