Reconstruction or extension road earth volume calculation method based on oblique photography technology

Abstract

The invention discloses a reconstruction or extension road earth volume calculation method based on an oblique photography technology, and the method comprises the steps of carrying out the photographing through an unmanned plane, generating preliminary oblique photography data, and forming an oblique photography three-dimensional live-action model; inputting the road initial elevation data into aroad design model to generate an initial roadbed cross section diagram; after the road construction is completed, building an oblique photography three-dimensional live-action model after the construction; replacing the initial elevation data of the corresponding position in the road design model with the constructed elevation data; generating a constructed roadbed cross section diagram; generating a roadbed cross section comparison diagram according to the same pile number, determining the pile spacing of the roadbed cross section comparison diagram, calculating the earthwork cross section area, calculating the road excavation and earth filling volume according to the adjacent earthwork cross section area and distance, calculating the road surface clearing earthwork volume, and countingthe road excavation volume to obtain the excavation and earth filling volume of the reconstructed and expanded road. According to the method, the earthwork volume calculation efficiency and accuracy are improved, and a reliable basis is provided for road construction earthwork volume settlement.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a method for calculating the earthwork volume of rebuilt or expanded roads based on oblique photography technology. Background technique [0002] my country's highway mileage base is huge, increasing at a rate of tens of thousands of kilometers every year, and the service life of highways is basically 10 to 15 years. At present, many existing roads in our country have reached the maximum service life and need to be rebuilt, or have been in disrepair for a long time and need major or medium repairs, or cannot meet the needs of development and need a large number of reconstruction and expansion, and a large number of roads are in urgent need of repair and maintenance. [0003] As a high-tech developed in the field of surveying and mapping in recent years, oblique photography technology has been more and more widely used in the fields of surveying, surveying and designing o...
