Just make sure not to extrapolate the end points, then recalculate your velocities. Otherwise you will need to take the derivative of inverse functions, which can cause problems numerically. | |
| Jul 1, 2015 at 13:12 | comment | added | Itay Perl | Yeah, I'm already using something similar to the second method to extract Euler angles. I know that technically I can numerically calculate their time derivatives, but since my attitude estimation algorithm is somewhat filtered, I hoped that a calculation directly from the angular velocities will be more reliable with low delay. | |
