Image fusion method, device and electronic equipment

Abstract

The invention relates to the field of image processing, in particular to an image fusion method and device and an electronic apparatus. At first, a first image and a second image are obtained, whereinthe first image is acquired by a first image acquisition system and the second image is acquired by the second image acquisition system; the geometrical offset between the first image acquisition system and the second image acquisition system is obtained, and then the preset first reference field angle of view corresponding to the first image acquisition system and the preset second reference field angle of view corresponding to the second image acquisition system are obtained. Secondly, the homography matrix between the first image and the second image is calculated according to the first reference field of view angle, the second reference field of view angle and the geometrical offset, and the first image and the second image are registered according to the homography matrix to obtain aregistered image pair, and finally, pixel fusion is performed on the registered image pair to obtain a fused image. The image fusion method provided by the invention has good image fusion effect.

Description

technical field [0001] The present invention relates to the field of image processing, in particular, to an image fusion method, device and electronic device. Background technique [0002] In recent years, with the development of UAV technology, UAVs have been widely used in exploration, reconnaissance, emergency, disaster relief and other fields due to their high efficiency, flexibility, low cost and other characteristics. The airborne optoelectronic pod is an important mission equipment in UAV exploration, reconnaissance and other tasks. The airborne optoelectronic pod is developing from a single-sensor imaging system to a multi-sensor imaging system. The image information fusion technology of the multi-sensor imaging system can effectively expand the reconnaissance range and scene detail information, and improve the performance of UAV image reconnaissance, target recognition and tracking . [0003] A typical multi-sensor photoelectric pod imaging system is a two-channel...

Problems solved by technology

On the one hand, this method requires a large amount of optical axis calibration work, the operation is complicated, and it is difficult to obtain ideal calibration results. On the other hand, the airborne photoelectric pod imaging system will , because the jitter of the airborne optoelectronic pod imaging system makes the calibrated optical axis prone to misalignment, which makes it impossible to accurately match the images captured by the airborne optoelectronic pod imaging system. Further, the airborne optoelectronic pod The fusion effect of the images captured by the imaging system is poor
