  • Laser Rangefinder Sensor
    Publication number: 20160109562
    Abstract: The specification discloses a pulsed time-of-flight laser range finding system used to obtain vehicle classification information. The sensor determines a distance range to portions of a vehicle traveling within a sensing zone of the sensor. A scanning mechanism made of a four facet cube, having reflective surfaces, is used to collimate and direct the laser toward traveling vehicles. A processing system processes the respective distance range data and angle range data for determining the three-dimensional shape of the vehicle.
    Type: Application
