Problems solved by technology

[0004] In the conventional road surface roughness measurement device based on the above-mentioned technology, it is necessary to use an expensive precision measurement device. In fact, clay is used to rub the road surface and measure the road surface roughness, because it is not using the actual road surface but the rubbing. Therefore, there are problems that it takes a lot of time and contains various errors, and it becomes an incorrect measurement.

Abstract

The invention relates to a non-contact pavement roughness measurement apparatus and method for measuring pavement roughness with non-contact mode, especially relates to a non-contact pavement roughness measurement apparatus for quantificationally representing pavement roughness by representing data acquired by illuminating laser beam to the pavement as phase value, and carrying out non-contact measurement such that the pavement can be measured quickly, and method thereof.

Description

technical field [0001] The present invention relates to a non-contact road surface roughness measuring device and method for measuring road surface roughness in a non-contact manner, and in particular to a method that can be quantified by expressing the data obtained by irradiating a laser beam on the road surface as a phase value. A non-contact road surface roughness measurement device and method that can express the road surface roughness accurately and can measure the road surface very rapidly by performing the measurement in a non-contact manner. Background technique [0002] Since the 1960s, road surface roughness measurement technology has been developed in order to investigate and analyze road performance and actual conditions, and since the 1990s, the development of directly applying road shape to vehicle driving analysis has been progressing. Develop step by step. [0003] This kind of road surface roughness measurement technology is paved and maintained by graspin...
