Inventor: FUKUHARA TOSHIHIKO
IPC: G01B21/20
Filed: 2001-06-25
Abstract: PROBLEM TO BE SOLVED: To provide a method of measuring the longitudinal section profile of a road for measuring easily and accurately the flatness of the road surface in its longitudinal direction. SOLUTION: With a first and second connecting rods 14, 15, aligned straight in a measuring block 10, a reference distance between the centers of a first and third rolls 11, 13, are divided in a plurality of measuring positions. When the measuring block passes over the reference distance in the longitudinal direction of the road to move the third roller from one measuring point to another, a rotary encoder detects the displacement angle made between the first and second connection rods at each measuring position. Based on the detected displacement angle value and the known height data at each measuring position in the measuring block located at the immediate preceding measuring position, the height data of the road surface at the measuring position is calculated, using the infinite impulse response filter calculation.  Thus unit road surface profiles at the reference distance are obtained and integrated, to obtain a longitudinal section profile of the road surface.
