Abstract
A first camera captures a first image of a scene, and a second camera captures a second image capturing thermal distribution across the scene. The first image is processed to detect one or more objects of interest in the scene and to identify respective surface characteristics of the objects. The first image is overlaid with the second image to identify regions of interest in the second image corresponding to the objects of interest in the first image. Values of pixels that belong to respective regions of interest in the second image are converted to temperature values using respective conversion functions that reflect respective emissivity values determined by the identified respective surface characteristics of the corresponding objects of interest in the first image. The temperature values are analyzed to monitor thermal conditions of the one or more objects of interest in the scene.
