本文提出了一种结合复杂施工现场特点的摄像机放置框架。该框架包括三个主要过程：(1)识别视觉监测决定因素、影响因素和摄像机放置条件；(2)问题定义与数学建模；(3)施工现场摄像机放置的混合仿真优化。为了评估所提出的框架的性能，对一个实际的建筑工地进行了案例研究。案例研究的结果显示了所提出的框架在寻找工地视觉监控摄像机的最佳数量、类型、位置和方向方面的潜力。本研究有三个主要贡献：(1)确定在复杂施工现场安装固定摄像机时需要考虑的关键因素；(2)为工地摄像机的放置制定系统框架；(3)在实际工地安装摄像机之前，对多个摄像机网络设计及其性能（即总成本和可见覆盖率）进行可视化和量化。
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.
