pom-genom3 3.4 released

Added by Anthony Mallet 28 days ago

Changes

  • Fix Jacobian of the "MRP to quaternion" function (#353).
  • Fix computation of the orientation measurements delta and covariance
  • Log variance of roll, pitch, yaw angles instead of those of the quaternion
  • Log euler angles of measurement offset instead of quaternion

pom-genom3 3.3 released

Added by Anthony Mallet 8 months ago

Changes

  • Add a configurable offset for each measurement frame
  • Log full quaternion instead of roll, pitch, yaw in log_measurements()
  • Check port existence in add_measurement()
  • Allow processing of measurements of an altimeter in body frame
  • Add set_filter_period() attribute to slow down the filter task
  • Be less verbose when not running at the requested period

pom-genom3 3.2 released

Added by Anthony Mallet over 2 years ago

Changes

  • Handle magnetometer in the measurement sources. Magnetometers must publish the magnetic field in the attitude part of the state, as an intrinsic measurement, using the vector part of the quaternion and a NaN scalar part.
  • Add set_mag() service, setting the expected magnetic field of the current location, in the NWU (X north, Y west, Z up) world frame.

pom-genom3 3.1 released

Added by Anthony Mallet about 3 years ago

Changes

  • Add an attribute selecting the prediction model (constant velocity or constant acceleration)
  • Fix the replay service so that it can read newer log files
  • Add the variance of the state in the state log file
  • Log the delay of measurements (current time versus measurement time stamp)

pom-genom3 3.0 released

Added by Anthony Mallet over 3 years ago

Changes

  • Switch to openrobots2-idl
  • Fix syntactic issues with older eigen
  • Display the covariance matrix diagonal when it becomes not positive definite
  • Allow non-integer history length (to make it less than one second)
  • Warn if computation is too slow (more than 110% of the period for 2 periods in a row)

pom-genom3 2.3 released

Added by Anthony Mallet over 4 years ago

Changes

  • Fix conversion from euler angles to quaternion in the 'replay' service
  • Abort processing of history after computing for longer than the period. This helps in keeping up the desired output rate when many old measurements are received.
  • Use aio(7) for logging and drop log entries when io requests are too slow
  • Add a 'decimation' parameter to the log_state function
  • Decouple the position and orientation measurements. This allows a measurement producer to provide only the translation part of a pose (e.g. GPS, ...) or the orientation part (e.g. compas).
  • Try to fix non positive definite covariance matrix in the state. Altough this does not happen in practice, it can still be triggered when receiving very wrong measurements.
  • Add README.adoc from latest genom skeleton

pom-genom3 2.1 released

Added by Anthony Mallet about 6 years ago

Changes

  • Implement a realistic process noise, with in particular all cross correlations
  • Reject measurements older than the current history (2s by default).
  • Add 'replay' and 'log_measurement' services to record/replay raw measurements
  • Be robust to port disconnection when reading measurement data
  • Export covariance on velocity and acceleration
