Display screen correction method and device

The invention discloses a display screen correction method and device. The method comprises the following steps: acquiring brightness and chrominance information of each lamp point through relative movement of image acquisition equipment and a screen body; conducting calculation according to the brightness and chrominance information of each lamp point to obtain a curved surface coefficient of each lamp point; performing curved surface correction on the image acquired by the image acquisition equipment according to the curved surface coefficient of each lamp point to obtain a corrected image;and correcting a display screen according to the corrected image. The technical problem that in the prior art, in the process of correcting each lamp point in the LED screen, the poor driving effect of the corrected LED screen cannot be overcome is solved. 本发明公开了一种显示屏的校正方法和装置。其中，该方法包括：通过图像采集设备和屏体相对移动采集各灯点的亮色度信息；依据各灯点的亮色度信息进行计算，得到各灯点的曲面系数；依据各灯点的曲面系数对图像采集设备采集到的图像进行曲面修正，得到修正后的图像；根据修正后的图像对显示屏进行校正。本发明解决了由于现有技术在对LED屏中每个灯点进行校正的过
