An automated method for comparing infrared 'IR' image data representative of a scene, without determining a direct alignment relationship between the IR image data, the method 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 image data and the first IR image data having been captured via an IR camera that includes a VL camera module having a VL sensor for capturing VL image data from a scene and an IR camera module having an IR sensor for capturing IR image data from the scene, the IR camera module having a first known spatial correlation to the VL camera module, the first VL point of view and the first IR point of view being related by the first known spatial correlation; 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 image data and the second IR image data having been captured via an IR camera having a VL camera module having a VL sensor for capturing VL image data from a scene and an IR camera module having an IR sensor for capturing IR image data from the scene, the IR camera module having a second known spatial correlation to the VL camera module, the second VL point of view and the second IR point of view being related by the second known spatial correlation; and generating IR comparison image data from the first and second IR image data by: 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 spatial 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 the IR comparison image data. 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 image data and the first IR image data having been captured via an IR camera that includes a VL camera module having a VL sensor for capturing VL image data from a scene and an IR camera module having an IR sensor for capturing IR image data from the scene, the IR camera module having a first known spatial correlation to the VL camera module, the first VL point of view and the first IR point of view being related by the first known spatial correlation; 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 image data and the second IR image data having been captured via an IR camera having a VL camera module having a VL sensor for capturing VL image data from a scene and an IR camera module having an IR sensor for capturing IR image data from the scene, the IR camera module having a second known spatial correlation to the VL camera module, the second VL point of view and the second IR point of view being related by the second known spatial correlation; and generating IR comparison image data from the first and second IR image data by: 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 spatial 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 the IR comparison image data. 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 spatial 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 the IR comparison image data.
