ROAD SURFACE PROFILE MEASURING INSTRUMENT
To measure an on-vehicle-type road surface profile having a high reproductivity in non-contact.SOLUTION: The measuring instrument includes: two non-contact displacement meters 21 and 22 for measuring the distance to a road surface; an inclinometer 23 for measuring the inclination angle of the non-contact displacement meters 21 and 22 in the arrangement direction; a distance meter 24 disposed in a vehicle including the non-contact displacement meters 21 and 22 and the inclinometer 23; and a calculation processing unit for receiving the data from the non-contact displacement meters 21 and 22, the inclinometer 23, and the distance meter 24. The travel direction of the vehicle is parallel with the arrangement direction of the two non-contact displacement meters 21 and 22, the measurement points of the two non-contact displacement meters 21 and 22 pass on a measuring line for measuring the road surface profile. The calculation processing unit synchronously acquires the data from the non-contact displacement meters and the inclinometer for each predetermined sampling period as the vehicle travels.SELECTED DRAWING: Figure 4
【課題】車載式で再現性の高い路面プロファイルを非接触で測定する。【解決手段】路面までの距離を測る２つの非接触変位計２１，２２と、非接触変位計２１，２２の配列方向の傾斜角を測定する傾斜計２３と、各非接触変位計２１，２２及び傾斜計２３が搭載された車両に設けられた距離計２４と、各非接触変位計２１，２２、傾斜計２３及び距離計２４からのデータを受ける演算処理部と、を備える。車両の進行方向と２つの非接触変位計２１，２２の配列方向とは平行であり、かつ２つの非接触変位計２１，２２の測定点は路面プロファイルを測定する測線上を通過し、演算処理部は、車両の走行に伴い所定のサンプリング周期毎に各非接触変位計と前記傾斜計からのデータを同期して取得する。【選択図】図４
