Abstract

The invention relates to a method and device for detecting dust on a screen, electronic equipment and a readable storage medium. The invention discloses a method for detecting dust on a screen. The method comprises the following steps: acquiring a first image of a to-be-detected screen displaying a first preset pattern; determining a dust detection area in the first image by using a pre-acquired mask image; and obtaining a dust position in the dust detection area. According to the embodiment, the position of the dust on the screen can be determined by using at most two images, the consumed time is short, and the detection efficiency is high. Moreover, objects around the screen shot due to the fact that the field of view of the camera is too large can be shielded through the mask image, only the screen area is detected, and the detection accuracy can be improved.

Description

technical field [0001] The invention relates to the field of control technology, in particular to a method, device, electronic equipment and readable storage medium for detecting dust on a screen. Background technique [0002] At present, in the process of producing LCD screens, if there is dust on the LCD screen, the dust will affect the defect detection of the subsequent screens. To this end, it is necessary to carry out dust detection on the LCD screen. In the related art, equipment such as a microscope and a translation stage are usually used to shoot a screen with dust multiple times, and use multiple images to determine the position of the dust, which takes a long time and reduces the detection efficiency. Moreover, during the shooting process, objects around the screen will enter the field of view of the camera device, which will affect the dust detection effect. Contents of the invention [0003] The invention provides a method, device, electronic equipment, and ...
