lens distortion

基本解释

Reset: Clicking this button will reset the lens distortion model to its default state.
复位：点击该按钮将重置镜头畸变模型到默认状态。
Shows lens distortion workflow based on re-distorting and compositing with the original image .
显示镜头失真的基础上重新扭曲和合成与原始图像的工作流。
Because of zero distortion at the centre of image, parameter calibration and lens distortion correction of CCD camera and DLP projector is separated with the points in center and all the rest points.
该方法根据图像中心附近点畸变量较小的性质，利用中心附近点和全场视点对CCD相机和DLP投影仪的内外部参数标定和镜头畸变修正进行分离。

However, these feelings never lasted long, because the shot would switch to another camera position which had worse contrast, or greater lens distortion, or shallower depth of field, and the illusion would be broken.
ENGADGET: BBC shows off 33-megapixel Super Hi-Vision Olympic footage, we ask: why?
Furthermore, we have achieved a wide horizontal viewing angle of 45 degrees by incorporating an optical lens that thoroughly suppresses unwanted elements such as aberration and distortion.
ENGADGET: Sony's head-mounted 3D visor is real, HMZ-T1 arrives in Japan November 11th
Offering exceptional optical performance to provide minimal distortion and chromatic aberrations while suppressing ghosting and flare, the advanced lens unit allows for higher shutter speed and captures stunningly clear images.
ENGADGET: Panasonic's Lumix line gets a lot more crowded
