| titleOfInvention | A grayscale correction method and related device for curved screen images |
| abstract | The present application discloses a grayscale correction method and a related device for a curved screen image, which are used to reduce the occurrence of excessive and uneven grayscale. The method of the present application includes: constructing a calibration image input curved screen, acquiring a plane photographed image and a prism reflection image; flattening the plane photographed image and the prism reflection image; marking the plane sampling control on the plane flattened image and the reflection flattened image respectively Area and surface sampling control area; generate plane gray data, plane gray mean, surface gray data and surface gray mean; perform mean decomposition on reflection flattened image; design piecewise linear transformation function of reflection flattened image; generate The surface corrects the grayscale probability distribution function; calculates the undetermined coefficients of piecewise linear transformation; generates N piecewise linear transformation functions and the corresponding undetermined coefficients of piecewise linear transformation; performs grayscale correction on the reflection flattened image; The flat flattened image is spliced to generate a spliced image of the curved screen. |
