Abstract

Earth-work calculation is the important data for estimating the optimal construction cost at the construction site. Earth-work calculations require the accurate terrain data and precise soil volume calculations. Drone surveying technology provides accurate topography in a short time and economic advantages. In this paper, a drone surveying technique was used to derive a high precision soil volume calculation system. Field demonstration were performed to verify the accuracy of the volume measurement system. The results of earth-work calculation using drone survey were compared with those of GPS surveying. In addition, the developed earth-work volume calculation algorithm is compared with the existing aerial survey software (Pix4D) to verify the accuracy.

토공량 산출은 건설현장에서 최적 공사비 산정을 위한 데이터로 정확한 토공량은 토목 공사의 설계 단계에서 시공단계까지 고려되어야 하는 중요한 요소이다. 토공량 산출을 위해서는 정확한 지형 자료와 정밀한 토공 부피 계산이 필요하다. 본 논문에서는 짧은 시간에 정확한 지형 파악이 가능하고, 경제성 측면에서도 장점을 갖는 드론 측량 기술을 이용하여 고정밀 토공량 산출 시스템을 도출하였다. 시스템의 정확도 검증을 위해 현장 검증시험을 수행하였으며, 드론을 이용한 토공량 산출 결과와 GPS 측량 장비를 이용한 토공량을 비교·분석하였다. 또한, 새롭게 개발한 토공량 부피 계산 알고리즘을 기존 항공사진측량 소프트웨어(Pix4D) 계산 방식과 비교하여 정확도를 검증하였다.
