Abstract

The invention discloses an information processing method and electronic equipment. A first collection unit and a second collection unit are arranged on the electronic equipment. The method comprises the following steps: collecting the running environment of the electronic equipment by the first collection unit so as to obtain three-dimensional point cloud data; collecting the running environment by the second collection unit so as to obtain two-dimensional point cloud data, wherein the three-dimensional point cloud data and the two-dimensional point cloud data are synchronously collected; determining the transformation relation between the two-dimensional point cloud data of adjacent moments in the two-dimensional point cloud data; and constructing the three-dimensional point cloud data to a target three-dimensional coordinate system on the basis of the determined transformation relation so as to form a data source for constructing a three-dimensional map. Through the technical scheme, the implementation cost for constructing the three-dimensional map can be reduced, so that the method can be applied to large-scale navigation and location scenes.

Description

technical field [0001] The present invention relates to information processing technology, in particular to an information processing method and electronic equipment. Background technique [0002] Indoor 3D maps are not only used in interior design, but also widely used in navigation in areas without global satellite navigation system (GPS) signal coverage. One of the 3D maps constructed by Octree Maps (Octo-Maps) is widely used in The application field of camera positioning and navigation. [0003] When constructing 3D maps in related technologies, the following methods are often used: [0004] 1) Using 3D cameras or 3D camera arrays to collect image data and construct 3D maps; [0005] 2) Use expensive 3D cameras to collect image data to build 3D maps in a large area; [0006] The above method 1) can only construct 3D maps in a limited area, which is only applicable to the field of interior design, and it is difficult to meet the needs of positioning and navigation appl...
