Hello, would you consider adding the equirectangular camera model?

What are the results? Got some cloud files?

Hi,
I have installed colmap_slam using conda and python 3.9.17 on a windows 10 machine. I downloaded EuRoC\MH_01_easy and updated the config.ini script with all path as you did in the sample ini files. I am using same Colmap version as yours: COLMAP-3.8-windows-cuda.
When I launch main.py, everything is fine until mapper is called. I could see the simulator working and features tracked in the opened window. Unfortunately, mapper call does not work and I don't know why.

Here is the log:

When it crashes, I tried to run it manually like this (not all options in your config):
.\COLMAP.bat mapper --image_path G:\RDVision\Micado\COLMAP_SLAM\imgs\ --database_path G:\RDVision\Micado\COLMAP_SLAM\outs\0\db.db --output_path G:\RDVision\Micado\COLMAP_SLAM\outs\0
it works but failed to create a sparse model but at least it is launched

Here is the log:

Do you experienced the same problem?
Is colmap result the problem or do I have a problem in subsystem.call in colmapAPI.py?
Thanks

Hi !

I just tried to run the code with LOOP_CLOSURE_DETECTION = True and set RootSIFT. Changed this part

In general, everything goes fine, I've downloaded VOCAB_TREE. The one thing that bothers me is that sometimes I get outliers. Am I doing anything wrong?

I've take 78 pictures, when I use it, the prompts come: "No more images available."
It could only handle two pictures.

Hi Luca!

Thank you for your great work! While running python main.py. processing always gets stuck at some point and after that, I get only

Have you ever seen something like that ?

Hello, I have some questions about COLMAP_SLAM for multi-camera scenario. Does the parameter "BASELINE_CAM0_CAM1" of config.ini only used to restore the scale? Is there any other difference between monocular and stereo COLMAP_SLAM?
