Integrated Positioning System

Topcon’s IP-S2 Mobile Mapping System overcomes the challenges of mapping linear features to a high level of accuracy. Accurate vehicle positions are obtained using three redundant technologies: a dual frequency GNSS receiver establishes a geospatial position; an Inertial Measurement Unit (IMU) tracks vehicle posse; and connection to the vehicle CAN bus or 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.

IP-S2 Vehicle configurations

The IP-S2 standard system includes three high-resolution LiDAR scanners that cover the vehicle path at ground level and sweep the adjacent areas to a distance of 30 meters. A high-resolution digital camera can be added to provide 360 degree spherical images at a rate of 15 frames per second. Other sensors can be integrated to provide total flexibility of system configuration for a wide variety of applications. Sensor inputs are recorded and time stamped at the rate of 15 nanoseconds.

IP-S2 System features

A web-based processing service with desktop PC interface is included as part of the IP-S2 system. Vehicle position and sensor output are integrated seamlessly into one continuous three-dimensional data stream that can be exported as industry-standard formats. GNSS data can be post processed for higher accuracy. The desktop software also includes a viewer enabling the user to review point clouds generated from LiDAR scanners and make linear measurements.

The IP-S2 provides fast, high accuracy data and dynamic imaging for any linear mapping project. The vehicle-mounted system can map data at normal travel speeds for roadway surface condition assessments and roadside feature inventories. Safety is increased by removing pedestrians from the travelled lanes. Other applications include pipelines, railways, utility corridors, and waterways. Homeland security and disaster management are critically important to our health, safety and welfare. The IP-S2 is perfect for 3D street-view city mapping and provides essential information for these applications
