Multi-target human body temperature tracking method and system including a thermal imager, an information processing unit and a warning device, which can target multiple specific objects to perform the motion tracking of multiple body temperature

The present invention discloses a multi-target human body temperature tracking method and system, which includes a thermal imager, an information processing unit and a warning device. The thermal imager is arranged in an area with pedestrians' route and configured to capture continuous images of people walking on the pedestrians' route so as to image to a human body thermal image. The information processing unit is used to analyze and process a color temperature distribution of the current human body thermal image to determine whether there is a person having a body temperature exceeding a preset body temperature value. When the determined result is affirmative, the person in the human body thermal image is set as a tracking target, and the tracking target is marked. The color temperature distribution of the next human body thermal image will then be analyzed and processed so as to track and calculate a movement trajectory information of the tracking target, and the movement trajectory information will be det
