A methodology and apparatus is described that registers images outputted by at least two video camera sensors that are not necessarily bore-sighted nor co-located together. Preferably this can be performed in real-time at least at video rate. The two video camera sensors can be either of similar or two different modalities (e.g., one can be intensified visible, while the other can be thermal infrared) each possibly with a different field-of-view. The methodology and apparatus take advantage of a combination of Inertial Measurement Units (IMUs) information and image registration between the two camera sensors from computational image processing. In one preferred embodiment, the system uses a rifle mounted weapon sight camera sensor and a helmet mounted sensor camera. The aim point of the weapon sight camera sensor (e.g., typically at the image center) zeroed to the true rifle aim point is digitally overlayed as a reticle on the video image from the helmet sensor, displayed on a head mounted display (HMD). In another embodiment pixel-level image fusion is displayed across the overlapping field-of-view of the rifle mounted camera sensor weapon sight with the helmet mounted camera image.

Method and apparatus for dynamic image registration

A methodology and apparatus is described that incorporates the use of thermal infrared imaging into a complete end-to-end face recognition system. Since thermal infrared primarily images emissive phenomenology there are advantages over video imaging in the reflective domain (e.g., visible, near-infrared) for face recognition, particularly with respect to image invariance in the presence of varying illumination incident on the subject. On the other hand video cameras in the reflective domain provide important image detail not apparent in thermal infrared imagery. Fusion of thermal infrared imagery with reflective domain (e.g., visible, near-infrared) imagery provides even further advantages. Embodiments of such systems that incorporate thermal infrared imaging for automatic face recognition are important for access control, verification, identification, and surveillance and monitoring.
