Hello everyone,
I want to use the intrinsic and extrinsic parameters of the camera calculated by Colmap to calculate the xyz coordinates of some point in the images in 3D world.(From pixel coord…

So you do not need the extrinsic camera calibration parameters at all, How is the initialization done? And I am wondering if the intrinsic parameters for the second camera are not used or the two came…

Hi Michael, thanks for your excellent research and for making the results public!
I have a few questions about the your research and implementation of Season-NeRF.
1. General NeRF requires es…

If I want to use iPhone 6, do I only need to provide the intrinsic and extrinsic parameters (fx, fy, ppx, ppy, tic_xyz)? What is tic_xyz BTW?
-
I have a point cloud, extrinsic parameters, intrinsic parameter as well as the projection matrix. How can I use it to project the point cloud to what the camera sees?

If we assume the car is going parallel to the lanes lines on flat ground, the direction of travel is the same as the extrinsics parameters which we can find using the vanishing point. Looking at openp…

Hi, I recently try to run colmap to get the camera parameters, but I found something confused. Colmap's input is DTU scans, when feature extraction I use **PINHOLE camera model** which is same as your…

@meyerj I am using insta360 air to record the rosbag. when I try to play I found that it has vertical shift in the mercator projection. I attached the image below here. Could you please help me to res…

Thank you for this excellent repo!
Now I made my own dataset with known camera parameters(extrinsics and intrinsics), and I have performed reconstruction on that dataset using all the features provid…
