Human life, health and social stability have been under the threat of infectious diseases, and its prevention and control work is of great significance. In the work of infectious disease prevention and control, rapid confirmation of patients' true track information is the most important part, and it is also the starting point and source of information generation for the whole work of infectious disease prevention and control. In order to discover the spread of specific diseases in time and space, and improve the efficiency and quality of prevention and control work, this paper designs a travel trajectory processing and visual analysis system for key personnel based on the public pedestrian trajectory data set. Its data processing uses the dwell point trajectory analysis algorithm to obtain the risk journey trajectory, uses mapbox to visualize the geospatial data of the risk journey trajectory, assists the prevention and control staff to confirm and report the trajectory, and optimizes the overall response process through the information module, so as to further strengthen the ability to prevent and control infectious diseases, shorten the response time of infectious disease reports, and improve the accuracy of prevention and control decisions.

The implementation of ultra-wide band (UWB) systems in a facility enables the real-time tracking of asset locations. However, commercial off-the-shelf UWB software for real-time tracking includes only top-down 2D projections of the environment and represents the active tags as simple dots, which do not reflect the tagged object's size. This representation may be sufficient for simple implementations but does not adequately portray the location of tags in relation to other objects in a spatially intuitive manner. The present work exhibits an application that provides users with an interactive 3D photorealistic environment to view UWB tagged assets. In the application, users can explore a mockup nuclear material production facility to observe tagged assets and obtain information about the asset and its movements. Additionally, the location data is filtered to improve the visualization so that users can make meaningful interpretations about the trajectory of the tagged objects. This software will be useful in many scenarios, such as asset tracking demonstrations, facility monitoring, and process management.
