Abstract

The invention discloses a method for automatically and quickly measuring the road structure parameters and a device for realizing the method thereof. A movable platform is provided with a vehicle attitude measuring device which is used for measuring the attitude parameters of the vehicle running on the road surface in real time; and a data processing system processes the attitude data and outputs the road structure parameters. The measuring device comprises a detection vehicle body, an attitude angle detector, a data processing system, a display device and a vehicle positioner; and the data processing system is respectively connected with the attitude angle detector, the display device and the vehicle positioner. The method can promptly discover the road sections where the geometrical parameters of the road surface do not meet the design specifications or design drawings and the harms generated by abnormal change of the road appearance such as settlement of local road section, improper cross slope of the road surface due to deformation of the subgrade, can use the computer to compare the data of all sections with the design value, and automatically screens out the non-conforming items so as to find the unqualified road sections, thus realizing the quick and automatic measurement on the road structure parameters.

Description

1. Technical field [0001] The invention relates to road measurement technology, in particular to a method for fast and automatic measurement of road structure parameters and a device for its realization. 2. Background technology [0002] Some structural parameters of the road, such as the radius of the transverse slope of the curve, the inclination angle of the transverse slope, and the radius of the longitudinal curve, etc., are very necessary for the acceptance of road engineering and daily maintenance and management. The usual way to obtain these parameters is to measure the elevation point by point with a total station and a ruler, and then calculate it. But in engineering practice, the measurement work is cumbersome and difficult, and often the accuracy is not high. [0003] With the advancement of computer technology, photoelectric technology, and high-precision measurement technology, my country has made great progress in road parameter measurement. For example, the...
