Description

technical field [0001] The invention relates to electronic technology, in particular to an information processing method and electronic equipment. Background technique [0002] In the process of creating a map such as Simultaneous Localization and Mapping (SLAM, Simultaneous Localization and Mapping), it is necessary to extract the surface such as the plane of the target object. In the prior art, the extraction of the surface mainly uses multiple adjacent points to estimate the normal vector of the plane, and according to the threshold condition. Determine the eligible subset of point clouds in the neighboring point cloud; this scheme of extracting planes is very slow in the calculation process, thus prolonging the cycle of map construction. Contents of the invention [0003] In view of this, the embodiments of the present invention provide an information processing method and an electronic device to solve the problems existing in the prior art, which can quickly extract t...
