Methods for analyzing thermal image data using a plurality of virtual devices and methods for correlating depth values to image pixels

Thermal imaging camera images are obtained from a thermal imaging camera that rotates through a plurality of stop positions. The camera captures images at a constant frame rate and at least some of the images correspond to stop positions. Thermal imaging camera images that correspond to a stop position are retained, while images that do not correspond to a stop position are discarded. Retained images are sent in a video stream to a video processor.
