Detection of Parking Position Based on Laser

This study uses laser to detect parking position and to analysis to get the corresponding exact map of parking lot or other place. Data preprocessing is by the way of median filter with least square method. Median filter could can commendably filter out isolated point in the laser data and reduce the effect of noise. Least square method could smooth laser data. Seeking out the parking position is by the way of partition of grid and clustering so that the map of parking lot could be known by the computer of vehicle. So it lays a corresponding basis for the path planning of vehicle.
