Embodiments of this disclosure provide an image fusion method, an electronic device, an unmanned aerial vehicle and a non transitory compute readable storage medium. The image fusion method includes: acquiring a first image; acquiring a second image; acquiring a mapped image of the first image based on a first transformation parameter and the first image, the first transformation parameter being used for characterizing a spatial transformation relationship between the first image and the second image; and weightedly superposing the second image and the mapped image to acquire a first fused image.
