3D Line Reconstruction
Hi, thanks for sharing your work.
I notice that, you show the 3D line reconstruction result in your oral presentation video(https://www.youtube.com/watch?v=HadE8YnCIRw), it looks great. Is that possible to share the 3D line reconstruction scripts with us?
Thanks again.
Hi, we used a modified version of COLMAP to reconstruct the lines in 3D. It is available here: https://github.com/vlarsson/colmap/tree/lines (note the branch "lines").
This code is really not optimal though, and it was only used once to create the demo. I would not rely too much on it. There are other open source tools that are probably more reliable, such as Line3D++. We will also release in the future a new open source package for line 3D reconstruction which is even better, but this will probably happen only in a few months. So stay tuned ;)
Could you please briefly describe how to use the modified COLMAP to generate the 3D lines?

Hello,did you solve this problem?
Hi, sorry for the late reply. I am afraid that you have to go through the code to understand how to use it. The general workflow should be similar to the original COLMAP, but this is too old to be relevant to create a ReadMe for the line part. Again, I recommend using Line3D++ instead.
Hello,I have used the original COLMAP for SuperPoints. Shoud I use the end-points match of SOLD2 lines as the 'points-feature match' for the triangulation？How to ensure the end-points match ?
You can use either SOLD2 or the SuperPoint descriptors to match the line endpoints.
Line triangulation is a quite complicated problem and is not solvable in a simple Github issue, so again I recommend using existing software that are still maintained :)

Hey，Sorry to bother you again. Now I have the pose of images by GPS(UTM coordinate system) ,the info of the monocular camera and the result of SOLD2.Could you briefly describe how to use this to generate the 3D lines? I couldn't find effective solution :( Thank you very very much.
