Hello all,

I`m using VICON Nexus 1.8.4 to measure subjects with the full body plug in and I want to compare the data with a accelero-, magento- and gyrometer combination. Basically, I've attached the sensor between LPSI and RPSI and want to compare the Roll, Pitch and Heading of the sensor with the same variables of the Pelvis segment measured with VICON. As I am not very knowledgable about rotational angles and conversions of such, I'm having difficulties understanding the output from VICON (Global-Pelvis; Helical Angles) and converting it into the desired Roll, Pitch and Yaw.

Can anyone guide me to the right direction or explain what I need to do?

Thanks in advance.

Hans
