Hi,
Can you explain which parameters are (distortion parameters) and which are (intrinsic parameters), such that in Pinhole parameters, there are up to 8 distortion parameters, and 2 focal lengths, a…

I remember talking to you guys about this at CVPR but I forget what the resolution was. I have run COLMAP with the default settings which generates a camera with `SIMPLE_RADIAL` parameters. However, w…

Hi all,
The method `Frame:UndistortKeyPoints()` uses the OpenCV function `cv::undistortPoints` to undistort points even when the camera model is `KannalaBrandt8` (OpenCV Fisheye model). This method…

Most real world 3D computer vision applications need to make use of some kind of lens distortion model. The most common for a pinhole camera is Brown-Conrady lens distortion.
See OpenCV for the mos…

I am trying to use colmap to reconstruct a scene from a set of fisheye lens images, 2048x2048 with FOV 180 degrees (camera: RADIAL_FISHEYE 2048 2048 600 1024 1024 0 0).
Sparse reconstruction works …

Thanks for the great work~
I use 3 camera(front_far, front_left front_right), 50 frames, panda 128 lidar on my own dataset, the other config is same as default cofig.

OpenCV 4.2 (but valid also for other versions).
In the documentation of `initUndistortRectifyMap()` we find:
> In case of a stereo camera, this function is called twice: once for each camera hea…

First——`pip install pytorch-lightning==1.5.10`can not match pip，so I use `pip install pytorch-lightning==1.9.0`
Second——the numpy should be`1.x `，I install `pip install numpy==1.23.5` .It work.
