Q : How to use multi fisheye camera in python?(pycolmap)

[Sa-Jaemin]

Hi!

I will use some of fisheye cameras in my project and I will do extrinsic calibration of them.

So, I want to use pycolmap!

However, I can't found example of fisheye camera....

How to use that? and I don't have any parameter. I want to using only camera images.

You can use any of the fisheye camera models to model camera intrinsics. However, Colmap does not support multi-camera systems. It only models individual cameras / images.

Oh! Thank you for your comment.

Yes... I use multi-camera system. but if them are same camera intrinsic parameter? (I know that is impossible. just I want to get roughly camera location) I want to solving that likes SfM... that can't to that?

The system is indoor! so, there is closed area.

I do not understand your question. What are you trying to achieve?

[Sa-Jaemin]

well... I trying to that.

1. I using some of fisheye cameras.
2. Fisheye cameras set to ceiling. that watching a floor.
3. Each cameras get a distance about 8~10m.
4. So, I get want to rectified full floor image!

so, when I get a full floor image, that using colmap.

can i do that?
