Patent ID: 8599264

Claim:
A method for comparing infrared (IR) image data representative of a scene, comprising: selecting a first image data set of a scene, the first image data set comprising first visual-light (VL) image data captured from a first VL point of view and first IR image data captured from a first IR point of view, the first VL point of view having a first known correlation to the first IR point of view; selecting a second image data set of the scene, the second image data set comprising second VL image data captured from a second VL point of view and second IR image data captured from a second IR point of view, the second VL point of view having a second known correlation to the second IR point of view; comparing the first VL image data to the second VL image data to determine an alignment correlation between the first VL point of view and the second VL point of view; correlating the second IR image data with the first IR image data using the first and the second known correlations and the alignment correlation; and comparing at least a portion of the first IR image data to a correlated portion of the second IR image data to generate IR comparison image data.
