摘要

CCTV plays an important role in police investigation and crime prevention. Besides tracking criminals and collecting digital evidence of crimes, modern CCTV systems can also improve public safety and the quality of human life by helping law enforcement find missing seniors with dementia and conducting crash reconstructions. However, investigating officers may need to spend hours searching possible CCTV cameras and collecting CCTV videos from public and private systems close to the incident scene. In addition, the current process for finding the right CCTV video frames that might serve as digital evidence is highly inefficient and time-consuming. Therefore, this study combines GIS, GPS tracking techniques, and CCTV to develop a more efficient system for searching for missing seniors with dementia. The first step is to define the patient's daily activity area and wandering behaviors on a GIS map. Then, a GPS tracking app can be used to record and monitor the patient's daily movement and possible deviation. When the senior leaves their normal route and thus is at risk, the app sends a warning to the family and/or police. Nearby CCTVs are identified and the key time period defined, and the corresponding videos automatically sent to the police authority. This study also defines several main dementia behavior patterns based on their GPS trajectories. Our results will contribute to different stages in the investigative process by providing key images in a short period of time and predicting the future trajectories of missing people over time.
