Detailed Description

template<class POSE>
class gtsam::FullIMUFactor< POSE >

Class that represents integrating IMU measurements over time for dynamic systems This factor has dimension 9, with a built-in constraint for velocity modeling

Templated to allow for different key types, but variables all assumed to be PoseRTV
