Poses fitted on the sphere #10
Comments
If you use quat and translation from ARKit (ARposes.txt) it should be "real". Check output and input formats. |
@Varvrar, can you please advise how ARKit computes these translation and quat values? I have a row of accelerometer and gyro data with timestamps, but I am unsure if we can derive similar ARKit information from them. |
@amughrabi for computes device poses ARKit use some visual inertial odometry algorithm (with mapping for corrections so it's rather some kind of SLAM). |
Thanks a million for the quick answer, @Varvrar!!! It is definitely helpful. I will have a try and let you know! |
Hi @Varvrar, I was working on VINS-MONO, and I realised that VINS-MONO wants 10 seconds frames for initialization, then it starts matching. It does not fit my dataset since my frame durations are less than 10 seconds. Any other options? |
Hello!
I tried to observe camera poses using COLMAP (by passed logged quat and translation vector to COLMAP), but faced the problem that camera poses from ios_logger look like something fitted on the sphere, but the real path of the camera definitely differs from the "spherical" one. Why does it happen? And how can I get the real poses?
Thanks!
