A system concept for 3D human flow management based on 3D spatial information

A controller who is responsible for safety makes decisions concerning measures for visitor safety using a human-based decision-making process. Many potential accidents that could be caused by human error lurk in the process. These accidents can be reduced by changing from a human-based to technology based decision-making process. A technology-based decision-making process can draw a controller's attention to trouble spots by data filtering, alarm filtering, and so on. The controller can thus obtain information on the occurrence of possible accidents proactively. The objective of this study is to suggest a system for 3D human flow management using a technology-based decision-making process. The system is divided into two parts: a 3D spatial information system and a human motion detection system. The former is built from 3D CAD and a geographic information system, and the latter is developed from image processing. This study shows the direction of system development and the method of application, and describes the contribution of the system.
