3.1 Network Architecture 如Fig.2 所示,我们的网络由三个模块组成:distorted lines perception module(DLP) 模块用来检测distorted lines;line-guided parameterestimation module (LPE) 从全局和局部角度来预测畸变参数Kd;rectification module作为几何形状和矫正参数之间的桥梁。给定一张大小为HxW的图像I,distorted linesmap...
SimFIR [21] is introduced as a straightforward framework for fisheye image rectification through self-supervised representation learning. 2.2 Fisheye correction datasets Current learning-based calibration methods mostly use supervised learning strategies to train their networks. These methods rely on the ...
When compared with the previous supervised methods, our method is more flexible and shows better practical applications for distortion rectification. The experiment results demonstrate that our proposed method outperforms state-of-the-art methods on the correction performance without any labeled distortion ...
Second, the decoder is overburdened during simultaneously reconstructing the content and structure of the image, resulting in vague performance. To solve these two problems, in this paper, we focus on the interpretable correction mechanism of the distortion rectification network and propose a feature-...
Self-Supervised Deep Learning for Fisheye Image RectificationThis is the official pytorch implementation of Self-Supervised Deep Learning for Fisheye Image Rectification. The code is written by Byron Hsu and Brian Chao from Department of Electrical Engineering, National Taiwan University. This work is ...
However when the exported ost.yaml is loaded in the "camera_info_url" and processed with image_proc, the rectification is not working correctly. I assume the distrortion model is wrong, however I'm not sure how to solve it or if it is an actual bug. I'm using Melodic. Here my ost...
Estimates new camera matrix for undistortion or rectification. 为什么引入了新的内参矩阵? 用来调节去畸变之后的视野的,去畸变之后一般视野会变小,是否需要保持原来的视野。 step2. initUndistortRectifyMap()这个函数的作用是初始化畸变矫正矩阵,将KDRP转换为map1和map2.之后就可以通过remap函数计算无畸变图像了. ...
