Embodiment Construction

[0040] The invention provides an image fusion method for an airborne photoelectric pod. A visible light imaging system and an infrared imaging system are installed in the airborne photoelectric pod. The principle of the present invention is to calibrate the optical axis consistency of the visible light imaging system and the infrared imaging system respectively during the zooming process, so as to meet the requirements of zooming optical axis consistency. The optical axis parallelism calibration system is used to calibrate the visible light imaging system and the infrared imaging system with high precision optical axis parallelism to make it meet the parallelism requirements. Through calculation, the infrared imaging system is associated with the visible light imaging system, and the zoom systems of the two imaging systems are controlled by the computer control chip to synchronize and link. The different focal length ranges of the two optical systems produce different zoom int...

Abstract

An image fusion method for an airborne optoelectronic pod comprises steps as follows: (1) adjusting the optical axis of a visible light imaging system and the optical axis of an infrared imaging system to be in a parallel state; (2) performing linkage zoom calculation with the focal length of the visible light imaging system serving as the reference to acquire the corresponding focusing length of the infrared imaging system; (3) calculating respective optical amplification multiples according to the focusing length of the visible light imaging system and the focusing length of the infrared imaging system, performing image scaling, calculating deviation angles according to positions of focusing length sections where the focusing lengths are located, and performing image translation compensation; (4) fusing images of the visible light imaging system and the infrared imaging system after image registration. With the adoption of the method, the visible light imaging system and the infrared imaging system in the pod are associated, infrared image features of targets and visible light image features are fused into one way of image video to be output, and the requirement of the optoelectronic pod for all-weather day-and-light reconnaissance is met to the greatest extent.

Description

technical field [0001] The invention relates to an image fusion method for an airborne photoelectric pod, which can realize real-time image fusion output of continuously zoomed infrared and visible light images, so as to simultaneously obtain two characteristic information of infrared and visible light of a target in one video. Background technique [0002] During the working process, the optoelectronic pod transmits video information to the ground operator through a video monitoring and control link, and the operator performs different operations according to the video information to achieve target search, tracking, positioning and other operations. Multi-load optoelectronic pods are usually equipped with infrared and visible light imaging systems, but the measurement and control link can only transmit a single channel of video to the operator at the same time. It's a big inconvenience. First, the single-channel video information is limited, which reduces the accuracy of t...
