1. A system for monitoring participants in a group, the system comprising: one or more thermal image capturing devices disposed at a location configured to capture one or more thermal images of a plurality of participants in an event; one or more visible image capturing devices configured to capture one or more visible light images of the plurality of participants, and a processing device communicably coupled to the one or more thermal image capturing devices, the once or more visible image capturing devices and an identification database, the processing device configured to receive a thermal image of the plurality of participants and a visible light image of the plurality of participants during the event, and receive identification data for at least one individual participant of the plurality of participants from the identification database, the processing device configured to perform a method during the event, the method comprising: identifying by an image processing module the at least one individual participant of the plurality of participants based on the one or more visible light images; correlating the at least one individual participant depicted by the one or more visible light images to the at least one individual participant depicted by the thermal image, wherein the correlating includes fusing the visible light image and the thermal image; calculating by a temperature monitoring module a heat profile of the at least one individual participant based on the thermal image; comparing, by a temperature monitoring module, the heat profile to a reference profile, the reference profile generated based on the identification data, determining whether a deviation exists between the heat profile and the reference profile, and based on detecting the deviation, calculating a magnitude of the deviation and determining whether a health risk exists based on the magnitude of the deviation; and generating a notification based on determining that the health risk exists.
