  • APPARATUS AND METHOD FOR DETECTING WORKER USING THERMAL IMAGING BASED ON ARTIFICIAL INTELLIGENCE
    Publication number: 20250046086
    Abstract: In an embodiment, an apparatus may include an image receiver configured to receive a thermal image from a thermal imaging camera, a worker detector configured to detect a worker from the received thermal image by using an artificial intelligence model, a hazard detector configured to detect a hazard based on whether the detected worker has entered a preset hazardous area in the thermal image, and a hazard controller configured to, in response to the hazard being detected, send a hazard notification and stop operation of a work machine in the hazardous area, where a position of the detected worker can be estimated in pixel units.
