the problem of parameter σp

[qco-11]

Dear Palanglois,

Recently，I try tweak σp of Line3D++ from 2 to 50. however, I only get almost 340 lines of meetingroom, far from 831. on the other hand,it working well to get 1016 lines of Andalusian. I don't know the best parameter to get decent input lines of meetingroom.Can you give me some advice?

Best regards,
qco

Dear qco-11,

Unfortunately, I don't have access to the intermediate data anymore.
One thing you can try is working on the undistorted images (which colmap should have generated) instead of the raw images when running Line3d++.

I hope this helps,
