Claim 0:
1. A method of acquiring images for photogrammetry, comprising:
positioning an object in a field of view of a thermographic camera to establish a first perspective;
applying heating or cooling to the object, creating a pattern of temperature differentiation across the object; and
capturing one or more thermographic images of the object with the thermographic camera;
repositioning the object or the thermographic camera to a second perspective;
capturing one or more thermographic images of the object in the second perspective while maintaining the pattern of temperature differentiation across the object;
in each of the thermographic images captured in the first and second perspectives, isolating the object from a background by determining a discernable temperature difference between the object and the background in each of the thermographic images captured in the first and second perspectives; and
generating a thermographic mesh based on the isolated object from the one or more thermographic images in the first and second perspectives.
