Road effective earth volume calculation method based on oblique photography technology

Abstract

The invention discloses a road effective earth volume calculation method based on an oblique photography technology, and the method comprises the steps: carrying out the photographing of a road regionthrough an unmanned plane, obtaining preliminary oblique photography data, and generating an initial oblique photography three-dimensional live-action model; inputting the elevation data into a roaddesign model; generating an initial roadbed cross section diagram in a road design model according to the elevation data; generating a constructed oblique photography three-dimensional live-action model after the road construction is completed; replacing the elevation data in the road design model with the constructed elevation data to generate a constructed roadbed cross section diagram; generating a roadbed cross section comparison diagram according to the same pile number, and calculating the cross section areas of effective excavation and earth filling squares; and according to the cross section areas and distances of the effective excavated and filled earthwork squares, calculating the effective excavated and filled earthwork squares, and taking the sum of the effective excavated andfilled earthwork squares of each road section as the effective earthwork volume of the road. According to the method, the scientificity and reasonability of road earth volume calculation are improved,and a reliable basis is provided for budget and settlement of road engineering.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a calculation method for road effective earthwork volume based on oblique photography technology. Background technique [0002] There are various methods for calculating or determining the earthwork volume of roads, but most of them consider single factors in the calculation process of earthwork volume, which makes it difficult to popularize and use them. For example, two commonly used earthwork determination methods in engineering are: 1) the design earthwork determined according to the survey data and technical parameter settings during the design process of the project; 2) the actual earthwork generated during the construction process. The designed earthwork volume is affected by multiple factors such as survey data, technical parameters, design software and designer experience, resulting in a large error between the earthwork volume and the actual situation. During ...

The designed earthwork volume is affected by multiple factors such as survey data, technical parameters, design software and designer experience, resulting in a large error between the earthwork volume and the actual situation

During the construction process, due to overfilling and overexcavation, the results of the actual earthwork volume will also be unbelievable.

Moreover, the above two earthwork determination methods are cumbersome to operate, low in efficiency, and poor in accuracy, which seriously affects the budget and settlement of road projects
