Problems solved by technology

[0004] However, for road sections with poor flatness, in order to ensure the driving comfort and safety of the testing equipment itself, it will intentionally avoid the location of the wheel tracks with poor road conditions during driving, which will lead to inaccurate measurement results, let alone true Reflect the flatness of potentially dangerous driving areas

Abstract

The invention provides a full-width flatness detection method based on a three-dimensional road surface, and belongs to the technical field of road detection. The method comprises the following steps: acquiring original elevation data of a road surface; establishing a three-dimensional pavement model according to the original elevation data, wherein the three-dimensional pavement model is used for representing the elevation of each position point in the pavement; performing region division in the three-dimensional pavement model to obtain a plurality of sub-regions, wherein the width and length of each sub-region are within a preset numerical interval, and the combination of the plurality of sub-regions covers the measured breadth of the pavement; for each sub-region in the plurality of sub-regions, calculating the flatness index of each sub-region by using a preset calculation method; and determining the full-width flatness of the calculation unit based on the flatness index of each sub-region, wherein the full-width flatness comprises the maximum flatness, the flatness mean value, the first wheel track flatness, the second wheel track flatness and the weighted flatness. According to the invention, the flatness condition of the road under the whole measurement breadth can be represented.

Description

technical field [0001] The present application relates to the technical field of road detection, in particular, to a method for detecting full-width roughness based on a three-dimensional road surface. Background technique [0002] The roughness of the road surface will affect the driving comfort of the driver and passengers, and will also cause the vehicle's vibration, running speed, tire friction and wear, etc. Therefore, a method to obtain the roughness of the road surface is urgently needed. [0003] In the prior art, the way to obtain the roughness of the road surface is mainly to detect the flatness of the corresponding longitudinal profile of the wheel tracks by measuring and testing equipment during driving, and use the flatness as the smoothness of the road surface. [0004] However, for road sections with poor flatness, in order to ensure the driving comfort and safety of the testing equipment itself, it will intentionally avoid the location of the wheel tracks wit...
