  • Infrared and visible-light image registration
    Patent number: 7924312
    Abstract: Methods and thermal imaging cameras are provided for registering visible-light and infrared images within a thermal imaging camera to reduce a parallax error in the images. Registration generally includes detecting a first feature set in the visible-light image data, detecting a second feature set in the infrared image data and generating a plurality of overlapping alignments of the infrared image data and the visible-light image data. A similarity figure is calculated as a function of the relative alignment of the first feature set and the second feature set for each alignment and the alignment with the desired similarity figure is selected. The images are aligned and the camera displays at least a portion of the visible-light image data and/or at least a portion of the infrared image data.
