 Accelerometers measure linear acceleration in three axes (X, Y, Z), while gyroscopes are sensors that measure angular velocity around three axes (X, Y, Z). Magnetometers measure the strength of a magnetic field in three axes (X, Y, Z). Combined, you get position, translational and rotational information about a segment. These signals are fused to estimate the pose of the associated segment.
-Visual3D extracts the pose information from IMU systems that write out an MVNX file. It does not read in the raw IMU data.
+Note that the coordinate systems of individual IMUs may not always be aligned.
