| 摘 要： | 提出一种几何校正方法以消除投影图像的畸变:通过查找后向映射表,借助双线性插值运算,对图像进行几何预畸变,使其变形为投影仪所需要的预畸变图像,然后将其投影到非平面物体上,便能让观察者看到无畸变的投影图像,从而实现投影图像畸变的校正。实验结果表明,该方法对于非平面几何形状所造成的投影图像畸变有良好校正效果,并具有一定的实用价值。 |
| 关 键 词： | 几何预畸变 后向映射 灰度级插值 |

| Abstract: | A geometric method of correcting is proposed to eliminate the distortion when an image is projected onto a non-planar object.According to the backward mapping table,the image is pre-distorted with a bilinear interpolation.Thus,when projected it appears normal to the observers.Experimental results show that the proposed method works well,and can be generalized into other applications. |
| Keywords: | geometric pre-distortion backward mapping bilinear interpolation |
