A Viewpoint Mapping Geometric Correction Technique for Image Display of Curved Screen

摘要：

　　Curved screen display image is deformed.Therefore,a geometric model for correcting image pixel position based on the viewpoint projection is proposed to correct the distorted image.The method is that the pixel J in the plane screen is mapped to the position I of the curved screen,and then the viewpoint D is intersected with the plane screen H position at the curved screen position I,finally the texture coordinates of the position H are corrected to the texture coordinates of J.In the OSG environment,the map is rendered by the camera and displayed on the screen in real time,and the corrected image is obtained by the viewpoint D.Results show that the corrected image is not deformed compared with the original image.After correction,the image returned to normal and the curved screen visual distortion problem is solved.
