Abstract

The invention discloses an unmanned aerial vehicle side slope and foundation pit excavation amount measuring device which comprises an unmanned aerial vehicle body and further comprises a flight control system for maintaining flight stability of an unmanned aerial vehicle, receiving an instruction responding to wireless transmission and completing corresponding operation. The device has the advantages that the important premise of calculating the earthwork volume is achieved by conducting three-dimensional modeling and visual expression on a slope area to be measured, A flexible low-altitude unmanned aerial vehicle carries a digital camera to obtain a slope sequence image, a dense three-dimensional point cloud of the slope body is generated according to a computer vision principle, and themanufacturing of the three-dimensional digital model of the slope body is realized. According to the technology, the side slope fine terrain can be quickly constructed, the operation cost and the labor intensity are effectively reduced, the limitation that a traditional single-point measurement mode is used for bringing surfaces point by point is overcome, the generated three-dimensional model can comprehensively express the overall shape and local detail characteristics of the slope, slope measurement is more accurate, and the earthwork filling and digging position and the earthwork volume can be perfectly solved.

Description

technical field [0001] The invention relates to the technical field of earthwork engineering, in particular to a device for measuring the excavation volume of slopes and foundation pits by unmanned aerial vehicles. Background technique [0002] There are high or low slopes and their side slopes everywhere on the surface of the earth. In civil engineering projects, we often encounter problems such as excavation of road cuttings, leveling of large sites, excavation of foundation pits for side slope treatment, etc., which require Determine the amount of soil to be filled and excavated on the slope. The calculation of earthwork is an important step in engineering construction. It is an important factor in project cost estimation and scheme optimization, and is also an important part of engineering design, which is directly related to project cost. [0003] In the current slope earthwork calculation, traditional manual calculation methods such as section method, or calculation b...
