Rigorous analysis of safety rules for vision intelligence-based monitoring at construction jobsites

Construction safety rules play a vital role in mitigating accidents and fatalities at construction sites. Many researchers are currently devoted to monitoring the rule compliance using computer vision-based approaches; however, such systems are still not mature for application at construction job sites. A single autonomous source’s job-site safety control such as CCTV is a nontrivial task that requires a detailed analysis of safety rules for a work-stage based compact vision intelligence system. This paper proposes a grounded theory methodology (GTM) to systematically classify the safety rules for practical implementation using vision intelligence technology. The rules are classified into four groups employing open coding, axial coding, and selective coding approaches: (1) before work, (2) with intervals, (3) after work, and (4) during work. The proposed GTM-based model is further linked with scene-capturing sources …
