Abstract

The invention provides an automatic focusing method and device, and relates to the technical field of projection. The automatic focusing method comprises: S1, obtaining rotation angle information about a driving motor and image data uploaded by a camera, the rotation angle information comprising a rotation angle; S2, extracting feature images in the image data; S3, calculating definitions of the feature images; S4, repeating the steps S1-S3 to find the feature image having the highest definition; S5, controlling the driving motor to rotate to a rotation angle corresponding to the feature image having the highest definition. The automatic focusing method and device provided by the invention can realize automatic focusing of a projector, the focusing precision is high, and a user does not need to manually operate an entire process, thereby improving the user experience.

Description

technical field [0001] The present invention relates to the field of projection technology, in particular to an automatic focusing method and device. Background technique [0002] A projector is a device used to project an image onto a target such as a screen. Most of the existing projectors focus manually. When focusing, a reference picture is preset in the system, and then the user uses the projector wheel to Or remote control for manual focus. [0003] However, with such a focusing method, the focusing accuracy is not high, and the user needs to open the focusing interface every time focusing, which is very cumbersome and has resulted in poor user experience. Contents of the invention [0004] In view of this, the purpose of the embodiments of the present invention is to provide an automatic focusing method and device to realize automatic high-precision focusing of a projector and improve user experience. [0005] An embodiment of the present invention provides an aut...
