Problems solved by technology

[0003] However, when the image includes weakly textured or non-textured areas (for example, a corridor with only white walls, a room with a solid color background, etc.), the existing SFM algorithm can only extract a small number of feature points from the image, so it will The reconstruction effect of the 3D model of the object is poor, and it is even difficult to reconstruct the 3D model of the object

Abstract

The invention discloses a three-dimensional reconstruction method based on point-line feature fusion and electronic equipment, and relates to the technical field of image processing, and the method comprises the steps that the electronic equipment can obtain a plurality of images including an object 1, and the plurality of images can be called an image set; each image in the set of images may display an object 1 in different states (e.g., angle, orientation, time, illumination, etc.). The electronic equipment can extract feature points (also called point features) and feature lines (also called line features) from the image set through a specified algorithm, and then the electronic equipment can match the feature points and the feature lines extracted between every two images in the image set. And a three-dimensional model of the object 1 is constructed based on the feature points and the feature lines with the established matching relationship.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a 3D reconstruction method and electronic equipment based on point-line feature fusion. Background technique [0002] With the development of terminal technology and the improvement of people's ability to process information, two-dimensional images can no longer meet the needs of work and life. Compared with two-dimensional images, three-dimensional models are the most intuitive structure for human beings, and observing objects and environments based on three-dimensional perspectives can enable people to process information efficiently. Therefore, 3D reconstruction has become one of the hot spots in the field of image processing technology. It establishes a mathematical model suitable for computer representation and processing for 3D objects, so that electronic devices can process, operate and analyze objects in a computer environment. At present, it is a ...
