这种跳转会引起相位信息的失真,因此需要进行相位解包处理,以消除这种跳转。 相应的绝对相位可以恢复为: 其中k(u, v)表示条纹顺序。值得注意的是,计算出的相位值不受环境光的影响,环境光应该被视为直接分量,因此可以近似地假设畸变相位(u, v)和未畸变相位(x, y)相等。例如,如图3所示,畸变相位(即透镜畸变)的点...
Examples are described for mapping primitives in circular images, generated from texture coordinate that compensate for rotation of cameras, onto respective mesh models to generate images representative of a 360-degree video or image. Portions of the rectangular images are blended to generate a ...
TL;DR: 提出了一种针对俯拍鱼眼图像(Downside Fisheye Image)的卷积方法改进——旋转卷积(Rotational Convolution, RC),在图像分割和目标检测任务上进行了实验,证明了它对鱼眼图像视觉任务的精确度提升和对计算开销较小的影响。 Downside Fisheye 近义词:Top-view Fisheye,Overhead Fisheye 论文接收:TIP 2023(IEEE Trans...

深度学习笔记(二十四)Learning to Calibrate Straight Lines for Fisheye Image Rectification 目录 回到顶部 Abstract 本文提出一种新颖的基于深度学习的方法来同时完成鱼眼镜头的内参标定和图像的畸变矫正。假定鱼眼图上的畸变线经过矫正后应该是直线,我们提出一种新颖的深度神经网络,在鱼眼镜头标定和图像矫正过程中施加显...
Source fisheye image. Transformation using the default settings. Since a 180 degree (in this case) fisheyecaptures half the visible universe from a single position, so it makes sense that it occupieshalf of a spherical (equirectangular) projection, which captures the entire visibleuniverse from a ...
