Abstract

The present application relates to a curved screen correction method, device, computer equipment and storage medium. The method includes: acquiring a first camera extrinsic parameter of a first LED box and a second camera extrinsic parameter of a second LED box in the curved screen image; obtaining coordinates according to the first camera extrinsic parameter and the second camera extrinsic parameter system transformation matrix; according to the coordinate system transformation matrix, the rotation matrix that rotates the second LED box to the same plane as the first LED box, and the first translation transformation matrix and rotation transformation of the second LED box before the rotation transformation are obtained After the second translation transformation matrix; according to the first translation transformation matrix, the second translation transformation matrix and the coordinate system transformation matrix, the screen light point of the second LED box is rotated to the plane where the first LED box is located, and the obtained A flat screen corresponding to the curved screen; performing screen correction on the flat screen to obtain a corrected curved screen corresponding to the curved screen. The correction effect of the curved screen can be improved by adopting the method.

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...
