Abstract

The invention relates to a method for measuring earth and rock by an unmanned aerial vehicle, comprising the following steps: S1 flight task planning and equipment selection; S2 performing flight task to obtain data; S3 establishing a three-dimensional model according to image data and geographic coordinate information; S4 combining engineering drawings and generating The three-dimensional model to calculate the earthwork volume of the survey area; S5 repeats the measurement at a certain time interval to calculate the engineering volume. The present invention can reduce the field workload and shorten the measurement period through the flight control system, satellite positioning system, flight data storage system and airborne camera set on the drone; avoid human intervention in the measurement process and affect the final measurement result, and The comparison and measurement of multiple sets of 3D models obtained by repeated measurement at a certain time interval can calculate the engineering quantity of earth and stone, which is beneficial to control the progress of the project.

Description

technical field [0001] The invention relates to a device and a method for measuring earthwork by an unmanned aerial vehicle. Background technique [0002] In earthwork construction, such as site leveling, water conservancy canal excavation, slope excavation, foundation pit excavation, etc., it is often necessary to calculate the earthwork volume, and use this to grasp the construction progress of the earthwork, control the use of funds, and ensure that the entire The smooth progress of the project, therefore, earthwork measurement and calculation is a very important task, the accuracy of the calculation results is related to the interests of both parties, in some engineering projects in reality, due to the accuracy and optimality of earthwork measurement and calculation And the disputes that arise are relatively common. How to accurately determine the earthwork has become a problem that people pay more and more attention to. [0003] The existing relatively common calculati...
