Benefits

 

The MT Manager is a Windows application for easy access to the full capabilities of Xsens’ Motion Trackers. It is the tool for getting acquainted with, configuring and analyzing the Motion Trackers. The MT Manager is also capable of recording and play-back the MT data.

Description

Real-time graphical presentation of various outputs of the MT-Tracker. The following functions can be carried out with the MT Manager:

  • Real-time 3D visualization of orientation
  • Real-time graphical presentation of:
       - Euler angles or Quaternions vs. time
       - Accelerometer, gyroscope and magnetic data vs. time
       - Position output (MTi-G only): latitude, longitude, altitude
       - GPS status and GPS time (MTi-G only)
  • Logging of orientation data, calibrated sensor data and/or binary sensor data
  • Exporting log files to other formats like ASCII and KMZ (Google Earth)
  • Post-processing of logged binary sensor data
  • Changing and viewing various device settings and properties, e.g.: 
       - Xsens sensor fusion algorithm scenario
       - Baud rate
       - Sample frequency
       - Synchronization settings
  • Selecting data output formats:
       - Orientation format (euler angles, quaternion, rotation matrix)
       - Calibrated sensor data (accelerometers, gyroscopes, magnetic field)
       - Raw sensor data (accelerometers, gyroscopes, magnetic field, GPS,  barometer, temperature)
       - Position output (MTi-G only): latitude vs. longitude, altitude vs. time
       - Velocity output (MTi-G only): velocity vs. time
  • Storing settings in the MT non-volatile memory

In addition, the MT Manager contains:

  • Low level communication data window (also possibility to send messages)
  • Complete documentation

The MT Manager handles up to 20 Motion Trackers and is Windows XP and Windows Vista compatible.

MT Development Tools

COM object API and DLL API (XsensCMT.DLL)

The Xsens Communication MT (CMT) API will help save time in interfacing in a reliable way with the Xsens Motion Trackers in a Windows environment. Direct interfacing gives full control and maximum flexibility. The example code can be easily extended to a user-specific program.

C++ classes and binary communication for any OS

The C++ Class and direct low level (binary) communication allows for reliable interfacing with the Xsens Motion Trackers in any (RT)OS environment. The C++ Class and direct low level (binary) communication is open source and can be used when hard real-time performance is required. The example code can be easily extended to a user-specific program.

Magnetic field mapper plug-in (MFM)

Quick, accurate and easy-to-use routine, making the Xsens Motion Tracker capable to provide reliable data in areas of homogeneous and constant magnetic distortion. By rotating the unit, the distorted magnetic field is accurately mapped. Magnetic field mapping is required only once upon installation.

Example source code

Example code is available for the following analysis programs and platforms:

  • Xsens MatlabMatlab/Excel (VBA) (COM Object API)
  • C/C++ (DLL API)
  • C/C++ (direct low level (binary) communication, library)

COM object API and DLL API (XsensCMT.DLL)

The API is an implementation of the MT low level communication protocol. 
 
The MT API contains the following features:
  • Data input/output handling: retrieve data and configure Xsens’ Motion Tracker
  • Achieve (soft) real-time performance
  • Message based low-level communication API
  • COM-object API (use the MT in any application software that supports COM)
  • DLL API (use the MT in programming language, e.g. C, C++)
  • Post-processing data with different settings of Xsens Kalman Filters (XKF)
  • Example C++ application code included
 

C++ classes and binary communication for any OS

The direct low level (binary) communication deals with the communication of the data that is calculated inside the Xsens Motion Tracker’s onboard processor. It contains the following features: 

  • Setting and storing (in MT non-volatile memory) of settings such as coordinate
  • Resets, baud rate, sample frequency and advanced filter settings
  • Full C++ class (library)
  • Documentation C++ source code example for use in user-specific code
  • Fully documented protocol
 

Magnetic field mapper plug-in (MFM)

Software plug-in for recalibration of the Xsens Motion Tracker when placed on ferromagnetic objects such as metal frames, cameras or vehicles causing a constant disturbance of the local magnetic field. 

  • Compensation for hard and soft iron effects
  • Storage of MFM recalibration data in MT non-volatile memory
  • 2D and 3D magnetic field vector mapping
