Hello,
I am trying to use RTAB-Map for offline SLAM. I recorded a video using my phone camera, then opened RTAB-Map Viewer, went to Detection, and selected the sensor type as RGB, but it did not work.
I think the problem might be one of the following:
Video format / camera type:
The phone camera may not provide true RGB data in the format expected by RTAB-Map. Also, from what I found online, when RTAB-Map cannot find a camera calibration file, it usually produces incorrect results, but at least something should appear — which is not happening in my case.
Missing depth or odometry information:
I am also wondering if RTAB-Map cannot work with videos recorded from a phone because there is no depth information and no odometry data.
So my questions are:
Is it possible to use RTAB-Map for SLAM with a recorded MP4 video from a phone camera?
What are the required steps to make this work?
What exactly is causing the failure in my case?
If anyone has successfully done something similar, I would really appreciate guidance on the correct setup and workflow.
Thank you!
