How to use the pErr files
Posted: Tue Jun 27, 2023 6:01 am
Hi all,
I was looking at the errors between my CMC output and RRA input and evaluating the errors between them. I was curious about the utility of using the pErr files. For context,here is the pErr for one joint (L hip rotation) after running CMC on an RRA output:
Looking at this graph, it appears that there is some deviation at about the 0.175s mark, which is quite substantial considering that I assume these values are in radians.
However, when I plot the CMC and RRA files side by side, the graphs appear like this:
So there is not nearly as much kinematic deviation as I would expect given the previous graph, especially considering this output is in degrees. Does anyone know where the disconnect may be? Does the pErr file not represent the kinematic errors the way that I think it does? I would definitely appreciate some insight if anyone could provide it.
Thanks!
