The invention discloses a precision self-checking pavement three-dimensional texture measurement method and system, and a storage medium. The precision self-checking pavement three-dimensional texture measurement method comprises the following steps: obtaining a three-dimensional reconstruction result of a pavement to be measured based on a binocular reconstruction device; acquiring a plurality of marking points of the to-be-measured pavement; acquiring position information of a plurality of mark points based on a binocular reconstruction device; calculating a theoretical parallax and a theoretical elevation of each marking point according to the position information; according to the position information and the three-dimensional reconstruction result, obtaining the actual parallax and the actual elevation of each marking point position; and calculating a deviation value of the three-dimensional reconstruction result according to the theoretical parallax, the theoretical elevation, the actual parallax and the actual elevation. According to the invention, precision self-inspection can be carried out on the three-dimensional reconstruction result of the to-be-detected pavement, the structure is simple, the operation is convenient, the reconstruction technology of the three-dimensional texture of the to-be-detected pavement can be perfected according to the precision self-inspection result, and the accuracy of the detection result is improved.

Description

technical field [0001] The invention relates to the technical field of road engineering detection, in particular to a method and system for measuring three-dimensional texture of a road surface with precision self-inspection, and a storage medium. Background technique [0002] Good anti-slip performance of the road surface is an important guarantee for driving safety, and it is also the need of the project quality itself. The purpose of accurately measuring the three-dimensional pavement texture is to better evaluate the anti-skid performance of the pavement and serve traffic safety. A large number of studies have shown that the pavement anti-skid performance is closely related to the three-dimensional texture, and the three-dimensional texture of the pavement is an important factor affecting the formation of the pavement anti-skid force. Research by the International Road Association found that both macroscopic texture and microscopic texture can affect the anti-skid perfo...

Problems solved by technology

However, this evaluation method often results in differences in resolution and measurement range due to differences in measurement equipment, making it difficult to achieve true evaluation of single-point measurement or local measurement; moreover, this evaluation method often uses global statistical average data as the evaluation result, Comparing the measurement results between different measurement devices, and this data processing method will weaken the noise component and invisibly increase the test accuracy, which is not the real measurement accuracy of the device to be evaluated
