Image composition method and electronic apparatus

Abstract

The invention provides an image composition method and an electronic apparatus. The image composition method comprises the following steps that under N different focal lengths, N images of a first photographed surface of an object are respectively obtained, each image in the N images is corresponding to one focal length in the N different focal lengths respectively, and each image has S pixels; S pixels of which the positions differ from each other are determined in N * S pixels in the N images; P focal lengths corresponding to P images where the S pixels of which the positions differ from each other are located are obtained; based on the P focal lengths, S pieces of depth information of the S pixels of which the positions differ from each other are obtained; based on the S pieces of depth information, the depth image of the object at the first photographed surface is constructed; and the j-th pixel in the S pixels of which the positions differ from each other is obtained. The j-th pixel in the S pixels of which the positions differ from each other is obtained through the following steps that first feature information of the k-th pixel on each image in the N images is contrasted; and the j-th pixel of which the first feature information satisfies a preset condition is determined from N k-th pixels.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to an image forming method and electronic equipment. Background technique [0002] With the development of computer vision technology and image processing technology, image-based 3D reconstruction technology has been greatly developed. Image-based 3D reconstruction methods include reconstruction methods based on two images and reconstruction methods based on multiple images. The reconstruction based on two images is also commonly referred to as stereo vision. Two images are obtained through a binocular camera or two single cameras. , and then perform 3D reconstruction by obtaining the parallax of corresponding points on the two images. The reconstruction based on multiple images is developed from the stereo vision technology of two images. The main principle of the stereo vision method based on multiple images is to use the stereo vision method of two images to obtain a ser...
