Systematic camera placement framework for operation-level visual monitoring on construction jobsites

Kim, J; Ham, Y; Chung, Y and Chi, S (2019) Systematic camera placement framework for operation-level visual monitoring on construction jobsites. Journal of Construction Engineering and Management, 145(4): 04019019, ISSN 0733-9364

Abstract

This paper proposes a camera placement framework that incorporates characteristics of complex construction jobsites. The proposed framework consists of three main processes: (1) identification of visual monitoring determinants, influencing factors, and camera placement conditions; (2) problem definition and mathematical modeling; and (3) hybrid simulation-optimization of camera placement on construction jobsites. To evaluate the performance of the proposed framework, a case study for an actual construction jobsite was performed. The results of the case study show the potential of the proposed framework to find the optimal number, types, locations, and orientations of cameras for jobsite visual monitoring. This research makes three main contributions: (1) identification of critical elements to be considered when installing fixed cameras on complex construction jobsites; (2) development of a systematic framework for camera placement on jobsites; and (3) visualization and quantification of multiple camera network designs and their performance (i.e., total costs and visible coverages) before installing cameras at actual jobsites.

Descriptive scope: 4 PCEA

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
