针对在观赏曲面显示屏在显示的平面画面时,画面产生的视觉畸变,需要对原始画面进行校正以得到等效于平面显示屏的视觉效果。提出采用平面画面几何投影到曲面,对曲面画面的横向像素和纵向像素分别进行校正的方法,其中横向像素的校正着力于解决画面左右边缘的拉伸问题,纵向像素的校正着力于解决画面在视觉上的桶形畸变问题。实验结果表明该算法在观赏者处于最佳观赏位置下观赏校正后的曲面画面,可获得等同于平面画面一致的视觉效果。
In view of the curved surface of the display screen in the display screen, the visual distortion of the screen, you need to correct the original screen to get the equivalent of flat-panel visual effects. The paper proposes a method of correcting the horizontal pixels and the vertical pixels by using the geometrical projection of the plane picture to the surface and the correction of the horizontal direction pixels in order to solve the stretching problem of the left and right edges of the picture. On the barrel distortion problem. The experimental results show that the proposed algorithm can observe the corrected curved surface when the viewer is in the best viewing position and obtain the same visual effect as the flat image.
