Problems solved by technology

[0004] However, after image registration of multi-frame images using traditional image registration methods, the noise reduction effect of different regions on the obtained image is poor, and the noise reduction effect at the boundaries of different regions on the image is quite different

Abstract

The invention discloses an image registration method and device, electronic equipment and a computer readable storage medium. The invention relates to the image registration method. The method comprises the following steps: carrying out global registration on a reference image block in a reference frame and a to-be-registered image block in a to-be-registered frame, and determining a global registration result of the reference image block; performing block matching on the reference image block in the reference frame and the to-be-registered image block in the to-be-registered frame, and determining a block matching result of the reference image block; and determining a target image registration result of the reference frame according to the global registration result and the block matching result. According to the invention, registration effects of the global registration result and the block matching result can be comprehensively considered, and the target image registration result of the reference frame is determined; the accuracy of image registration of the reference frame and the to-be-registered frame is improved, and a noise reduction effect of an image obtained by fusing the reference frame and the to-be-registered frame is further improved; and meanwhile, the registration effects of the global registration result and the block matching result are comprehensively considered, so that the noise reduction effects at boundaries between different regions on the image obtained by fusion are small in difference.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to an image registration method, device, electronic equipment and computer-readable storage medium. Background technique [0002] With the continuous development of image processing technology, image processing methods based on multi-frame images have emerged. Due to the influence of the parameters of the camera module itself, the information collected by a single frame of image is always limited. Therefore, by adopting the image processing method based on multi-frame images, image processing can be performed on multi-frame images to synthesize a clearer image, so as to restore more image details. [0003] The first step in adopting the above image processing method is to perform image registration on multiple frames of images. Among them, image registration refers to correcting the position of the non-reference image based on the reference image in the multi-fr...
