We propose a vehicle location estimation method using in-vehicle laser radar and an ordinary GPS to improve the accuracy of vehicle locations obtained by a GPS.
The proposed method estimates vehicle locations by matching the laser radar data series of a traveling car to a radar map.
The radar map consists of a geographical position on the road map and the corresponding laser radar data at the position.
We also describe how to construct the radar map.
The estimation is performed in two stages.
The first stage categorizes traffic lanes by examining the lateral gaps of the laser radar data series to a standard series.
The second stage accurately matches each pair of the laser radar data series from the same traffic lane by DP matching, then obtains the vehicle location from corresponding laser radar data in the radar map.
In experiments using 10 data sets collected while cars traveled the same route with multiple traffic lanes, our method showed the ability of the vehicle location estimation and the cruising lane classification methods. |
