Web-based interface for 3D sensor calibration

MITTA v1.0 is a web-based interface for calibrating 3D sensors mounted on a mobile platform. The tool supports manual and data-driven calibration with intuitive 3D data visualisation views that support calibration parameters validation.

  • Extrinsic 3D calibrations and temporal offsets
  • Platform independent web application
  • Intuitive 3D data visualisation
  • Advanced 3D calibration algorithms
  • Highly configurable

SUPPORTED SENSORS

Mitta supports the following sensor modalities:

  • 3D LIDAR(s)
  • IMU
  • Radar
  • Odometry
  • RTK-GNSS

FEATURES

MITTA supports finding the extrinsic calibration parameters and temporal offsets between sensors mounted on a mobile platform. Accurate synchronisation and calibration between the sensors is a requirement for using PAIKKA, a map-based positioning software by GIM Robotics.

 

THE MAIN FUNCTIONALTIES INCLUDE:

  • Extrinsic calibration and time offset estimation (odometry, IMU, GNSS, 3D LIDARs)
  • Calibration data validation
  • Versatile and intuitive 3D data visualisation 
  • Sensor frame manipulations
  • Motion-based calibration (data-driven optimisation)

 

MITTA ARCHITECTURE

MITTA consists of two main parts: front-end and back-end. The front-end is a platform independent web application for 3D data visualisation and controlling the calibration process. The front-end is a web application where the user can see all the relevant 3D data, control the calibration functionalities, and adjust all sensor frames. The back-end is responsible for the heavy data-driven optimisation.

The backend refers to the part of MITTA running on a cloud server. The back-end handles most of the heavy computations related to calibration, whereas the front-end is responsible for the controls and data visualisation. Some data processing is done on the front-end to ensure smooth user experience.

The calibration data files can be large, and they are managed by Google cloud service. The front-end runs on any browser, whereas the back-end runs on a cloud server. Data is managed on the cloud server.

BENEFITS

Time
