Wavy Road Elevation Measurement Based on the Principle of Inertia

Precision Level is widely used to measure road elevation. The measuring process needs several cooperating people to complete. The measuring error is not easily to be controlled due to the artificial influence. A wavy road elevation measurement method is proposed in this paper based on the principle of inertia. This equipment mainly consists of a gyro, a three-axis accelerometer and a photoelectric encoder. When moving on the road at a high speed, it can real-timely measure the running speed and the pitch angle of the car, from which the road elevation can be obtained by data processing. The advantage of this method is simple, high speed and easy to achieve; it can be applied to measure the wavy road elevation.
