Abstract

The invention provides a control method and an electronic device. The control method is applied to one or more electronic devices which are used for map building. The control method comprises the steps that (1) a first object in the environment where the electronic device is located is detected; (2) a sensor of the electronic device obtains the orientation information of the first object under the situation that the first object is detected; (3) the electronic device sends a request used for obtaining the identification information of the first object to a user; (4) the electronic device receives response information, comprising the identification information of the first object, to the request from the user; (5) the electronic device carries out map building according to the orientation information of the first object and the response information. Due to the fact that the control method and the electronic device can build a map according to the orientation information, obtained by the electronic device itself, of an object in the environment where the electronic device is located, and the identification information received from the user, building of the map can be convenient, cost is reduced, and real-time location and navigation are facilitated.

Description

Technical field [0001] The invention relates to a control method and electronic equipment. Background technique [0002] SLAM (Simultaneous Localization and Mapping: Simultaneous Localization and Mapping) is also called CML (Concurrent Mapping and Localization: Simultaneous Mapping and Localization), which refers to instant localization and map construction. SLAM was first proposed by Smith, Self and Cheeseman in 1988. Due to its important theory and application value, SLAM is considered by many scholars to be the key to realizing a truly fully autonomous mobile robot. [0003] SLAM can be described as: when the robot starts to move from an unknown location in an unknown environment, it locates itself according to the position estimation and map during the movement, and at the same time builds an incremental map based on its own positioning, so as to realize the robot's Autonomous positioning and navigation. [0004] Among them, in the process of SLAM exploring unknown environments...
