  • Apparatus and method for detecting worker using thermal imaging based on artificial intelligence
    Patent number: 12705898
    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.

  • SYSTEMS AND METHODS FOR RELIGHTED IMAGE GENERATION
    Publication number: 20260134589
    Abstract: A method, apparatus, non-transitory computer readable medium, and system for image generation includes obtaining a source image and a lighting input that indicates a lighting condition for the source image. An image generation model generates a relighted foreground image based on the source image. A relighted background image is also generated based on the lighting input. The relighted foreground image depicts a foreground element with the lighting condition and the relighted background image depicts a background element with the lighting condition. The relighted foreground image and the relighted background image are combined to obtain a relighted image, wherein the relighted image depicts the foreground element and the background element with the lighting condition.
