Method for correction of barrel distortion due to wide-angle lenses based on a polynomial;
为了修正广角镜头的桶形畸变，本文提出了一种基于样条函数的修正方法。
Through transforming pixels in the image, this paper adopts L multinomial address correction to realize barrel distortion correction of images.
桶形失真直接影响了对图像的分析理解，为了得到比较完好的图像，对拍摄到的图像进行几何校正是十分必要的。
This value controls the amount of distortion. Negative values correct lens barrel distortion, while positive values correct lens pincushion distortion.
此值控制着畸变的量。负数值校正镜头圆桶状面性畸变，而整数值校正镜头针尖状点性畸变。
This allows pin distortion and barrel distortion, as well as trapezial distortion to be corrected by remote control in the back-projection image display device (1).
由此，在背投式图像显示装置(1)中可以实现基于远程操作的枕形失真、鼓形失真和不等腰梯形失真的校正。
