Abstract: Provided are a visual positioning method, a non-transitory computer-readable storage medium and an electronic device. Surface normal vectors of a current image frame is obtained. A first transformation parameter between the current image frame and a reference image frame is determined, by projecting the surface normal vectors to a Manhattan coordinate system. A matching operation between feature points of the current image frame and feature points of the reference image frame is performed, and a second transformation parameter between the current image frame and the reference image frame is determined based on a matching result. A target transformation parameter is obtained, based on the first transformation parameter and the second transformation parameter. A visual localization result corresponding to the current image frame is output, based on the target transformation parameter.

Abstract: A virtual object display method, a non-transitory computer-readable storage medium and an electronic device. The virtual object display method includes operations as follows. Localization is performed on the first device to determine a pose of the first device in a target coordinate system; a pose of a second device in the target coordinate system is determined, where the second device is configured to play audio; a virtual object corresponding to the audio is determined, and a pose of the virtual object in the target coordinate system is determined based on the pose of the second device in the target coordinate system; and in response to the second device is playing the audio, the virtual object is displayed on a display interface of the first device according to the pose of the first device in the target coordinate system and the pose of the virtual object in the target coordinate system.
