Integrated Sensor Platform for Autonomous driving

 

The Integrated Sensor Platform (ISP) of ANavS includes a large variety of sensors in a single platform: 3 Multi-Frequency, Multi-Constellation GNSS receivers, an industrial-grade IMU, a CAN interface for wheel odometry data, a barometer, two cameras, and a 3D LiDAR are all integrated into a single platform for easy and fast installation. The first camera provides images at very high frame rates with a global shutter. The second camera is a stereo camera with an integrated visual-inertial odometry. The 3D LiDAR point cloud data are processed by the ANavS SLAM (Simultaneous Localization and Mapping) to obtain precise position and attitude information. Moreover, semantic maps are determined by deep learning and further used to enhance the SLAM performance. The GNSS, INS and odometry data are tightly coupled in the ANavS sensor fusion, which is further enhanced by the position and attitude information obtained from the camera and LiDAR SLAMs.

Multi-GNSS, Multi Frequency RTK/PPP

  • Precise absolute RTK positioning:
    horizontal accuracy:
    sigma = 1.0 cm
    vertical accuracy:
    sigma = 2.0 cm
  • Precise absolute PPP positioning:
    horizontal accuracy:
    sigma = 15 cm
    vertical accuracy:
    sigma = 20 cm
  • Precise absolute attitude (heading, pitch, roll):
    sigma = 0.25° for 1 m distance
    between the GNSS antennas
