Abstract

The invention discloses a multi-view image fusion method and device, computer equipment, and a storage medium. The method includes the steps: acquiring a to-be-fused image of a target object at a standard shooting view angle and a reference image of the target object in a non-standard shooting view angle; calculating optical flow information between the to-be-fused image and the reference image; performing the fusion of the to-be-fused image and the reference image according to the optical flow information to obtain a target image of the target object in a standard shooting view angle. Throughemploying the above technical scheme, the method can improve the fusion speed of multi-view images, and reduce the manpower and material resources in the image fusion process.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to a multi-view image fusion method, device, computer equipment and storage medium. Background technique [0002] In recent years, with the reduction of the cost of camera sensors, multi-camera, multi-camera and even dense array multi-view image acquisition devices have gradually become the mainstream trend of image acquisition. [0003] Multi-view image acquisition devices generally use image fusion synthesis algorithms to fuse the images collected at various shooting angles to generate images of the target scene. Therefore, compared with pictures collected by single-camera image acquisition devices, they have higher It has the advantages of high efficiency, low noise, and large amount of information. At present, the following challenges need to be faced when performing multi-view image fusion: there are parallax, occlusion, etc. between the pictures collected und...
