Outdoor display screen detection and repair method, device and equipment and storage medium

Abstract

The invention discloses an outdoor display screen detection and repair method, device and equipment and a storage medium, and the method comprises the steps: controlling an unmanned plane to shoot anoutdoor display screen through a preset shooting rule, and obtaining the images of all regions of the outdoor display screen; splicing and combining the regional images to obtain a combined image, andanalyzing the combined image to obtain color spot compensation data of the combined image; performing color spot repair on the outdoor display screen according to the color spot compensation data. The stability problem caused by a complex mechanism is solved through mobile shooting of the unmanned aerial vehicle; the problem of insufficient resolution of the camera due to overlarge size of the display screen is avoided; the dependence on the spatial layout of a plant is eliminated, the limitation of space and distance is broken through, the detection on a large-size display screen is more flexible and convenient, and the complete brightness of the whole display screen is well restored by combining a plurality of images in an image splicing and combining manner; and the effect and the stability of color spot repair are improved.

Description

technical field [0001] The present invention relates to the field of panel display, in particular to an outdoor display screen detection and repair method, device, equipment and storage medium. Background technique [0002] Color spot defects (Mura) will inevitably appear in the production process of flat panel displays; the optical extraction Demura equipment in external compensation is an integrated high-precision professional signal generator, standard optical measuring instruments, automatic crimping and control adjustment software in An integrated pigmentation defect repair system. [0003] The color spot defect repair system needs the camera to obtain the brightness information of the display screen. This process requires a certain distance between the camera and the display screen, and as the size of the display screen increases, the distance between the two becomes farther; the current color spot defect repair system can Displays that meet the existing size can work...

AI Technical Summary

Problems solved by technology

[0005] The main purpose of the present invention is to provide a method, device, equipment and storage medium for detecting and repairing outdoor display screens, aiming to solve the need to design complex mechanisms and occupy a large amount of time when using multi-camera shooting for displays with large screen sizes in the prior art. Space, the actual production line operation is more difficult technical problems
