Problems solved by technology
[0002] In modern highway construction, asphalt pavement is widely used in high-grade highways due to its short construction period, high driving comfort, low noise, and easy maintenance in the later stage. The surface of the structural layer is uneven or the road surface roughness of some road sections is poor. During the subsequent road operation, with the repeated load of vehicles and the action of natural environmental conditions, a series of road diseases will appear or even aggravate, destroying the pavement structure and shortening the road surface. The overall age of the road

The invention provides a road flatness detection method and system based on a three-dimensional laser scanning technology. The method comprises the following steps: performing three-dimensional data acquisition of multiple observation stations on the surface of a construction structure layer of a road under construction by adopting three-dimensional laser scanning, splicing data of adjacent observation stations of a detected road section, and unifying a coordinate space; performing data processing on the obtained three-dimensional point cloud data to obtain accurate digital-analog data of the surface of the structural layer of the construction section; the method comprises the following steps: performing section line subdivision on digital-analog data, calculating an international flatness index under data of each section line, and calculating a lane flatness index according to a certain weight so as to detect and evaluate the flatness condition of each lane in a construction section. The road flatness detection method and system based on the three-dimensional laser scanning technology can be applied to detection of the surface flatness condition of the road structure layer of the construction road section, the international flatness index is obtained, and further detection of the surface construction quality of the construction section structure layer can be accurately and conveniently carried out.
Description
technical field [0001] The invention relates to the technical field of road engineering, in particular to a road flatness detection method and system based on three-dimensional laser scanning technology. Background technique [0002] In modern highway construction, asphalt pavement is widely used in high-grade highways due to its advantages of short construction period, high driving comfort, low noise, and easy post-maintenance. The uneven surface of the structural layer or the poor smoothness of the road surface in some sections of the road will cause or even aggravate a series of road diseases in the subsequent road operation process, with the repeated load of the vehicle and the action of the natural environment, destroying the pavement structure and shortening the road surface. The overall useful life of the road. [0003] As an emerging measurement technology, 3D laser scanning technology has the advantages of rapid real-time high-density acquisition of target surface ...
