Determining optimal camera configurations considering various unique conditions of complex construction jobsites is still challenging. To address such a challenge, this paper proposes a new, systematic camera placement framework that incorporates the characteristics of construction jobsites
Generalizing the optimal configurations of fixed cameras to be installed on complex construction jobsites with minimized costs is still challenging; for instance, the actual coverage and/or total costs of installed cameras are likely different from project managers’ expectations. To fill such a knowledge gap, this paper proposes a new systematic camera placement framework that incorporates the characteristics of complex construction jobsites for visual monitoring
Summary
A large amount of visual data is being collected for construction jobsite monitoring. According to the authors’ interviews with construction experts who had several experiences with installing digital cameras on jobsites, practitioners were observed to generally carry out camera placement based on their knowledge or experience rather than systematic guidelines Their decisions occasionally come with acceptable visual monitoring performance (in term of camera coverage or total costs) but often encounter difficulties with determining proper camera configurations because of a number of unique conditions to be considered in given complex jobsites: for example, power supply, data transmissibility, and occlusion effects. Those conditions make the manual camera placement process time consuming and labor intensive and may cause performance deviations in jobsite visual monitoring. This paper discusses contributions and future works in the conclusions
