RTAB-MAP camera pose
Hi
I am running RTAB-MAP according to the answer here as I don't have /tf topic in my bag. It seems to be working fine.
But I am having trouble getting the camera pose. I tried using File->Export poses RGBD-SLAM format, on RTABMAPVIZ. But I get this
1473175676,151992 0,000000 0,000000 0,000000 0,000000 0,707107 -0,707107 0,000000

Assuming this in time, x, y, z, qx, qy, qz, qr format, I don't seem to be getting the correct quaternion value. Shouldn't qr be close to 1 ?
Also tried rostopic echo -p /rtabmap/mapGraph/poses > poses.txt from here but I get this in terminal
WARNING: no messages received and simulated time is active.
Is /clock being published?
and this in txt file

for the same run. The quaternion value seems OK for the first timestamp. But the output has some extra values (looks like its missing a timestamp after 8 values) in the lines that follow.
Please let me know what I'm doing wrong here.
Thank you
