Management of Construction Fields Information Using Low Altitude Close-range Aerial Images

Abstract

Compare to other industrial sites, the civil construction work not only takes longer time but also has made of complicated processes, such as the integrated management, process control, and quality control until the completion. However, it is hard to take control the construction sites, since numerous issues are always emerged. The study purposes on providing the dataset to synthetically manage and monitor the civil construction site, main design, drawings, process, construction cost, and others at real-time by using the low altitude closerange aerial images, based on UAV, and the GPS surveying method for treating the three-dimensional spatial information quickly and accurately. As a result, we could provide the latest information for the quick decisionmaking following from planning to completion of the construction, and objective site evaluation by the highresolution three-dimensional spatial information and drawings. Also, the present map, longitudinal map, and cross sectional view are developed to provide various datasets rapidly, such as earthwork volume This is an Open Access article distributed under the terms of the Creative Commons Attribution Non-Commercial License (http:// creativecommons.org/licenses/by-nc/3.0) which permits unrestricted non-commercial use, distribution, and reproduction in any medium, provided the original work is properly cited.

Tecnologias emergentes para o controle de qualidade da construção civil

“…Su et al (2014) pesquisaram sobre a qualidade do uso de RFID na construção, desenvolvendo um método avançado de condição de contorno entre RFID e GPS. Cho et al (2014) pesquisaram sobre o uso de UAVs de baixa altitude em conjunto com o sistema de GPS para melhorar o gerenciamento e controle da construção. Fang et al (2016) desenvolveram um sistema hibrido de visão na nuvem para o rastreamento de elementos e materiais dentro do canteiro de obras através do uso de UAVs.…”

“…A última tecnologia abordada neste artigo, VANTs teve o número de estudos mais baixo nesta revisão, não sendo possível encontrar uma clara tendência no desenvolvimento de pesquisas deste tema, com alguns autores focando no uso da tecnologia para o controle dos materiais no canteiro de obras (CHO et al, 2014;FANG et al, 2016) ou na tecnologia em si (ENTROP e VASENEV, 2017;ZHANG e HU, 2018;HAMLEDARI et al, 2018). Isto mostra que esta área ainda possui um grande potencial para desenvolvimento de pesquisas, principalmente para o uso desta tecnologia no auxílio do controle de qualidade de obras de grande porte, facilitando a obtenção de informações que seriam de difícil acesso sem o uso destes veículos, devido ao tamanho e extensão das obras.…”

Construction of 3D Digitizing Data Using Aerial Photographs Acquired by UAV

“…The global market of UAV is expected to grow from about $5.2 billion in 2010 to about $11.4 billion by 2022, with the commercial market expected to grow at an annual rate of over 14% per annum by 2018 [7][8][9]. The domestic UAV market, with the global growth of the commercial UAV market, is rapidly growing at more than three times the rate of the previous year [10][11][12]. UAVs in the field of spatial information have attracted much attention in terms of the speed and economics of data acquisition, and various studies have been conducted [13][14][15].…”
