Michigan Scientific provides instruments that can pair with LiDAR sensor technology, high-resolution cameras, and GPS technology allowing users to collect precise geospatial data for incredibly detailed mapping and indoor/outdoor 3D modeling.
Overview
Michigan Scientific’s Wheel Pulse Transducers (WPT) are distance measuring instruments (DMI) that provide accurate reliable distance measurements for georeferencing and mobile mapping systems. DMIs include wheel sensors or odometers that calculate distance traveled based on the number of the vehicle’s wheel rotations. The encoder inside the DMI uses optical technology to generate pulses or output signals representing partial revolutions of the vehicle wheel to determine the precise linear distance traveled. Compatible with vehicle-based mobile mapping systems (MMS), the Wheel Pulse Transducer (mounts directly to the vehicle wheel and) integrates with position and orientation (POS) and imaging modules to provide crucial distance data to supplement GPS/GNSS signals.
Slip Angle Sensors can be used in conjunction with DMIs and MMSs for mobile mapping in areas where satellite signals fail. Using the optical sensor can result in more accurate data without worry of inertial drift or relying on dead reckoning. TrueSlip is a critical tool in vehicle dynamics testing, tire testing, and ADAS testing.
Michigan Scientific has a variety of wheel mounting hardware available. With different-sized wheel plates, collet lug nut extensions, and restraining devices, mounting instruments is made easy for any car or light duty truck wheel. Custom mounting hardware can be created if the sizes available are not applicable.
