Questions about sensor-to-segment calibration #2

Open Vincy-Ying opened 1 year ago

Vincy-Ying commented 1 year ago

Thanks for your project. In the process of sensor-to-segment calibration, s2s_offset is used to rotate acc, gyr, mag. S2s_offset is represented in NWU coordinate while acc, gyr, mad are shown in NED coordinate. May be right to complete rotation between two coordinates? Meanwhile, segment orientations are acquired by using the above acc, mag, gyr in NED and s2s_offset in NWU, and what is the coordinate of segment orientations belonging to? Lastly, the segment orientations are also converted to NWU coordinate. I am confused about these problems related to coordinate transformation.

Hi!

May I inquire that how to know acc, gyr, and mad are in NED coordinate system?

Best regards, YuFu
