The invention relates to a direction measurement method and device and a terminal, and belongs to the technical field of computers. The method comprises the steps that when a compass APP operates through the terminal, a camera is started, and a real scene is acquired through the camera; the direct facing direction of the camera is determined according to the compass APP; the direct facing direction is displayed in the real scene. The device comprises a real scene display module, a direction measurement module and a direction display module. According to the direction measurement method and device and the terminal, the problem that the terminal cannot provide the direction in the real scene for a user can be solved, and the effect of expanding the direction measurement function of the terminal is achieved.
