no camera_trajectory.csv

[HaMengder]

I have recorded 100 videos, and 54 of them have error messages: no camera_trajectory.csv. What is the cause of this error? Is it the chaotic environment?

I encountered this when SLAM fails.
It could not localize the demonstration trajectory in the map you built in the first step.
Try building the map again.

Any tips on the map building data collection? i collected multiple batch of data under the same environment but some it can generate csv and some can't. Thank you @ErinZhang1998
