Abstract

The invention relates to the technical field of projection, in particular to a focal length adjusting method and device, projection equipment and a storage medium. The focal length adjusting method comprises the following steps: obtaining a projection scene image shot by a camera; determining an original output image corresponding to the projection scene image; selecting a feature region from theoriginal output image, then determining a target region corresponding to the feature region from the projection scene image, and generating a focal length adjustment instruction according to the definition representation data of the target region, so that the projection equipment executes a focal length adjustment action according to the focal length adjustment instruction. The projection equipment and the storage medium provided by the embodiment of the invention, the reliability of the adjustment effect can be ensured, and meanwhile, the complexity of the adjustment process can be reduced.

Description

technical field [0001] The present application relates to the field of projection technology, and in particular, to a focal length adjustment method, device, projection device, and storage medium. Background technique [0002] A projection device, also known as a projector or projector, is a device that can project images or videos onto a projection surface (eg, a wall, a screen). At present, in the process of using the projection equipment, in view of the problem of heat and out of focus of the projection equipment, the user usually needs to manually perform the focus adjustment action to realize the adjustment of the focus of the projection equipment. Therefore, the reliability of the adjustment effect cannot be guaranteed, and the adjustment The process is complicated. Contents of the invention [0003] The purpose of the embodiments of the present application is to provide a focus adjustment method, device, projection device and storage medium to solve the above probl...
