Abstract

The present disclosure provides a method and device for constructing a map, and a storage medium, wherein the method includes: determining whether the newly registered image belongs to a key frame image according to the associated features between the newly registered image and the existing key frame image; Based on the newly determined key frame image, a new map point is added to the constructed three-dimensional map.

Description

technical field [0001] The present disclosure relates to the field of computer vision, and in particular, to a map construction method and device, and a storage medium. Background technique [0002] At present, 3D reconstruction technology has broad application prospects in the fields of cultural relics protection, positioning and navigation, scene roaming, augmented reality, and industrial measurement. Three-dimensional reconstruction methods can be divided into two categories: incremental reconstruction methods and global reconstruction methods. [0003] The incremental reconstruction method can achieve high reconstruction accuracy when reconstructing small-scale scenes. However, as the scale of the scene expands, the reconstruction efficiency drops sharply. At the same time, due to the frame-by-frame registration method of the incremental reconstruction process, it will lead to large scene reconstruction. Drift phenomenon occurs. The global reconstruction can directly e...
