Description

The POLYFUSION-MAPPER is a precise, highly integrated data collection and sensor fusion solution for mobile 3D mapping and self-driving applications. The system synchronizes and collects such sensory inputs as LiDAR(s), Camera(s), and annotates them with precision centimeter-level location and time data. The systems can collect Radar data, as well.

The POLYFUSION-MAPPER system supported by the post-processing, easy to use, software, allowing the fusion of lidar and camera data into a single point cloud file, creating instant colorized 3D models with the centimeter-level accuracy. More types of sensors or multiple similar sensors integrated upon request.

The system includes precision dual-frequency RTK GNSS/INS with centimeter-level accuracy, the sensor fusion board, and ample data storage.

The system GNSS/INS features dual-frequency RTK with a centimeter-level accuracy and compact, robust design. The PolyNav 2000 family provides superior performance during GNSS signal outages through its tightly coupled GNSS and INS systems. Furthermore, the system is capable of continuously generating highly accurate attitude measurements regardless of whether the platform is moving or static. Also included is a digital quadrature counter which can be used as a distance measurement indicator (DMI) to improve the performance in challenging environments. The system can output an internal PPS signal and timestamps so that sensor fusion can be done even without GPS PPS. A Heave message for the Marine applications also included.

The PolyNav 2000 provides performance close to FOG systems and ideal for such applications as  HD Mapping, Bathymetry, Autonomous Driving and many more.
