Fully Integrated High Density 3D Laser Scanning and Digital Imagery Mobile Mapping System.
Topcon’s IP-S2 HD Mobile Mapping System overcomes the challenges of mapping linear features to a high level of accuracy. Accurate vehicle positions are obtained using three technologies: a dual frequency GNSS receiver establishes a geospatial position; an Inertial Measurement Unit (IMU) tracks vehicle attitude; and connection to external wheel encoders obtains odometry information. These three technologies work together to sustain a highly accurate 3D position for the vehicle even in locations where satellite signals can be blocked by obstructions such as buildings, bridges, or tree lines.
The IP-S2 HD Mapper features a rotating LiDAR sensor with 64 internal lasers that capture targets up to a range of 100 meters. The sensor's 360 horizontal field of view provides full coverage of scan areas with a 30 vertical field of view to minimize laser shadowing. A six-lens digital camera system produces 360 degree spherical images at user-defined time or distance intervals. Five optional single-frame cameras can be added for focused, forward-facing views. Topcon's High Density HD Mapper system produces the highest-density point cloud available in mobile mapping systems today.
