摘　　要：图像在采集和处理过程中会产生几何失真,降低图像质量.要消除几何失真就要恢复像素原来的空间关系和灰度变化.插值法能够对几何失真图像进行校正,通过实例具体讨论了双线性插值在图像几何失真校正中的应用.There will be geometrical distortion in image collecting and treatment which will affect the image quality, to remove it, the original space relation and gradation must be resumed. Interpolation is able to correct image geometrical distortion. The application of bilinear interpolation in the correction of image geometrical distortion is studied with exam- ples in the paper.
