Abstract

A robot, a map building method and a storage medium are provided. The map building method includes building an initial map according to a scene image captured by a robot in real time when the robot traverses a work area. The initial map includes a first map including a mapping of the work area and a map coordinate system, and a second map including a scene feature extracted based on the scene image, a geometric quantity of the scene feature and the scene image, which are stored in association with the pose of the robot in a scene database when capturing the scene image, the pose including a coordinate and an orientation of the robot, and the scene feature including a feature of a feature object in the scene and/or a feature of the scene image.
