Abstract
(EN)
The present invention relates to a method for projection picture correction. The method comprises: acquiring orientation information of a mobile device at a specified location, the specified location being identical to the orientation of a projecting device; and determining a correction plan for the projecting device on the basis of the orientation information, the correction plan being used for correcting the picture angle of the projecting device. Also provided in the present invention are a device for projection picture correction, a mobile device, and a storage medium. The method and device for projection picture correction, the mobile device, and the storage medium allow the projection picture correction to be implemented automatically on the basis of the orientation information of the mobile device, are convenient and quick, and provide great user experience.
