Abstract

The invention relates to an arc-shaped screen correction method and device, computer equipment and a storage medium. The method comprises the following steps: acquiring a first camera external parameter of a first LED box body and a second camera external parameter of a second LED box body in an arc-shaped screen image; obtaining a coordinate system transformation matrix according to the first camera external parameter and the second camera external parameter; according to the coordinate system transformation matrix, obtaining a rotation matrix for rotating the second LED box body to the sameplane as the first LED box body, a first translation transformation matrix of the second LED box body before rotation transformation and a second translation transformation matrix of the second LED box body after rotation transformation; according to the first translation transformation matrix, the second translation transformation matrix and the coordinate system transformation matrix, rotating screen lamp points of the second LED box body to the plane where the first LED box body is located, and obtaining a plane screen corresponding to the arc-shaped screen; and performing screen correctionon the flat screen to obtain a corrected arc screen corresponding to the arc screen. By adopting the method, the correction effect of the arc-shaped screen can be improved.

Description

technical field [0001] The present application relates to the technical field of LED screen calibration, in particular to a curved screen calibration method, device, computer equipment and storage medium. Background technique [0002] Screen calibration is an important link in the production process of LED displays. At present, the calibration of LED displays is generally done by collecting data on the LED screen through brightness and chromaticity collection tools, and correcting the screen through the collected photos. This method is aimed at conventional Calibrating on the screen can achieve a better calibration effect. [0003] However, for figure 1 For the curved screen shown, when this method is used for correction, the information is collected once through the camera. Since the block of a single photo is not considered in the same plane, after correction using the existing algorithm, it will cause differences between different planes. exist as figure 2 In the obvi...
