An indoor positioning method includes: receiving a first measurement parameter obtained by a first device by measuring a second device in a first coordinate system, where the first measurement parameter includes a first angle and a first distance, the first angle is an angle of the second device in the first coordinate system, and the first distance is a distance of the second device relative to an origin of coordinates of the first coordinate system; determining a first spatial position of the second device in the first coordinate system based on the first angle and the first distance; and determining a spatial position of the second device in a geodetic coordinate system based on the first spatial position and a conversion relationship between the first coordinate system and the geodetic coordinate system.

Indoor positioning method and device

An electronic device includes a first graphics processing subsystem, a second graphics processing subsystem, and a screen. The first graphics processing subsystem includes a first application processor, a first graphics processing unit, and a first memory. The second graphics processing subsystem includes a second application processor, a second graphics processing unit, and a second memory. The first graphics processing unit renders a first GUI. The screen displays the first GUI. The second graphics processing unit renders a second GUI, and the second GUI and the first GUI belong to different interface types. The screen displays the second GUI. A display processing method applied to the electronic device is also provided, wherein the first graphics processing subsystem can be switched to the second graphics processing subsystem based on complexity of a to-be-displayed GUI.
