Embodiment Construction

[0040] It should be understood that the specific embodiments described herein are only used to explain the present invention, but not to limit the present invention.

[0041] The existing detection method acquires the projection image of the projection device at a preset projection distance, and acquires the contamination information of the projection device according to the projection image. Due to the high requirements of the test environment for obtaining the projection image, in order to obtain a more accurate detection result, the projection distance is generally relatively long. Therefore, the existing detection method has the disadvantage of high detection cost.

[0042] In order to solve the above-mentioned defects, embodiments of the present invention provide a contamination detection method for a projection device, a detection device, and a computer-readable storage medium, wherein the contamination detection method for a projection device mainly includes the followin...

Abstract

The invention discloses a method for detecting contamination of a projection device, comprising the following steps: obtaining a projection image of a second projection device at a first projection distance; obtaining first contamination information corresponding to the projection image; converting the first dirt information into second dirt information corresponding to a second projection distance, wherein the first projection distance is smaller than the second projection distance; performing the second projection according to the second dirt information Contamination judgment of the device. The invention also discloses a detection device and a computer-readable storage medium, achieving the effect of reducing the detection cost.

Description

technical field [0001] The present invention relates to the technical field of projection detection, and in particular, to a contamination detection method of a projection device, a detection device, and a computer-readable storage medium. Background technique [0002] The projection device is a device that enlarges and projects an image and displays it. During the assembly process of the projection device, due to the influence of the process environment, tiny particles such as dust easily enter the assembled projection device, and these dusts can easily affect the projection of the projection device. Therefore, after the assembly of the projection device is completed, the projection screen of the projection device needs to be detected. [0003] The existing detection method acquires the projection image of the projection device at a preset projection distance, and acquires the contamination information of the projection device according to the projection image. Due to the ...
