one or more imaging devices oriented toward the surface, the imaging devices comprising one or more imaging sensors capable of generating red-green-blue (RGB) images, long wavelength infrared (LWIR) images, or depth images; and

a processor and memory, including a trained model for generating the contact pressure map, the trained model trained with a dataset of human subjects in lying poses comprising physical parameters of the human subjects, a plurality of pressure maps, and corresponding plurality of images of the human subjects in lying poses, the plurality of images comprising images generated from at least one imaging modality, including an RGB imaging modality, an LWIR imaging modality, or a depth imaging modality;

wherein the processor is in communication with the one or more imaging devices to receive one or more images of the human subject lying on the surface, the images of the human subject comprising RGB images, LWIR images, or depth images, and a source to receive physical data representing one or more physical parameters of the human subject lying on the surface; and

wherein the processor and memory is operative to generate, using the trained model, a pressure map of the human subject lying on the surface based on the one or more images of the human subject lying on the surface and the one or more physical parameters of the human subject lying on the surface.
