“…The sensor detects the lightprofile reflected from the obstacle. When the mutual geometry of the sensor and the light stripe projector is known, based on the image coordinates of the reflected obstacle profile, the range coordinates of the stripe points can be defined and the location of the obstacle determined accordingly.When the system has detected an obstacle, its location is defined and the information passed on to the control system of the machine [7]. The machine can use the location information in different ways; the vehicle can be guided around the obstacle, stopped before collision or guided near to the obstacle for further instructions.…”
