Abstract
Although traditional inertial profiler can measure profile under high speed condition(>120km/h)with high preci-sion(～0.1mm),it is sensitive to chassis rotational movement.Tradition inertial profiler assumes chassis is horizontal.In this scenar-io,one axis accelerometer sensor is enough.However,if the profiler is mounted far away from weight center of the vehicle,the rota-tional movement is not negligible.The paper proposes a new method,by adding a gyroscope sensor to measure the rotation angle and two axes accelerometer to calculate acceleration in absolute vertical direction.The profiler can overcome the negative impact raised by the rotation and accomplish higher precision profile measurement by angle calibration.关键词
