Electronic device, control method, and non-transitory computer readable storage medium

A control method, suitable for an electronic device, comprising:

• storing a physical map and a database, wherein the database comprises a plurality of predefined common object images corresponding a plurality of common object 3D data;
• capturing an environmental image;
• obtaining a first common object image from the environmental image;
• extracting a plurality of feature points from the environmental image;
• adjusting a plurality of first feature points of the feature points when a first common object 3D data of the plurality of common object 3D data is aligned to the first common object image;
• and
• updating a SLAM map constructed by the electronic device according to the plurality of feature points of the environmental image.

A non-transitory computer readable storage medium, wherein the non-transitory computer readable storage medium comprises one or more computer programs stored therein, and the one or more computer programs can be executed by one or more processors so as to be configured to operate a control method, wherein the control method comprises:
