As part of a project I’m working on now I’m trying to figure out the best way to get synchronized IMU data. I’m looking here and don’t quite understand the statement:
To be clear, the idea here isn’t to take an IMU measurement exactly at the same time as we take a picture but rather to correctly time stamp our images so as to provide accurate data to our VIO algorithm.
I guess I’m trying to understand why that’s the case and why it’s easier to match timestamps rather than just include the data.
In connection with this, it looks like internally, sensor_data_combined is being published at 250 hz. Is there a way to increase that (and are there any negative ramifications)?
