Abstract
A method for a terminal to measure an angle, includes: displaying a horizontal reference line, a measurement line, and an object being imaged by a camera on a display interface of the terminal, a plane determined by the measurement line and the horizontal reference line being parallel with the display interface, and the measurement line being relatively static with respect to the display interface; during a process in which the terminal is turned to cause, on the display interface, an edge of the object to be parallel with the measurement line, obtaining one or more angles between the measurement line and the horizontal reference line; and determining an angle obtained when the edge of the object is parallel with the measurement line as an angle between the object and a horizontal plane.
