Abstract

The embodiment of the invention discloses a galvanometer working state determination method and device and a computer storage medium. The method comprises the following steps: acquiring a unit image for detecting the working state of the galvanometer; segmenting the unit image into a plurality of sub-unit images; respectively calculating the inclination angle difference of each sub-unit image before and after the galvanometer vibrates; and determining the working state of the galvanometer according to the inclination angle difference. According to the embodiment of the invention, the working state of the galvanometer can be accurately and efficiently determined.

Description

technical field [0001] The present invention relates to the technical field of projector detection, and more specifically, to a method, device and computer storage medium for determining the working state of a vibrating mirror. Background technique [0002] At present, with the popularization of projectors and the improvement of communication speed, users are becoming more and more enthusiastic about high-definition and ultra-high-definition picture quality. As the resolution increases, the hardware cost and device size will also increase exponentially. Therefore, it has become a trend to output 4K (3840*2160) high-definition images on 1080p hardware through galvanometers. [0003] When the projector outputs 4K images on 1080p hardware through the galvanometer, whether the galvanometer works normally will directly affect the output of 4K image quality, that is, it is necessary to make an accurate judgment on the vibration of the galvanometer. Usually, the vibration of the ...
