Abstract

The invention provides a road surface flatness detection method based on line scanning three dimensions, and relates to the technical field of road surface measurement engineering. The method comprises the following steps: acquiring original elevation data of each cross section along the breadth direction of a road by utilizing a line scanning three-dimensional measurement device, and obtaining first elevation data corresponding to the original elevation data; correcting the first elevation data of each cross section according to attitude parameters corresponding to the line scanning three-dimensional measurement device, the calibrated working distance, the working distance of the line scanning three-dimensional measurement device in the elevation direction when the line scanning three-dimensional measurement device collects each cross section, and the preset number of measurement points of each cross section; obtaining second elevation data of each cross section, and further determining second elevation data of each vertical section perpendicular to each cross section; and according to the second elevation data of each longitudinal section, determining the flatness of the pavement by using an international flatness index IRI calculation formula. Therefore, the accuracy of determining the pavement flatness can be improved.

Description

technical field [0001] The present application relates to the technical field of road surface measurement engineering, in particular, to a three-dimensional line-scanning-based method for detecting road surface roughness. Background technique [0002] Road surface roughness not only affects the driving comfort of drivers and passengers, but also causes vehicle vibration, tire wear and vehicle running speed instability, so the determination of road surface roughness is a very important task in road surface measurement engineering . [0003] At present, the IRI (International Roughness Index, International Roughness Index) is usually used to evaluate the road surface roughness, and three-dimensional laser scanning can be used to obtain the road surface data required for calculating the International Roughness Index IRI. [0004] However, there is a certain deviation between the road surface data obtained by using the existing technology and the actual road surface data, which...
