Request for extension of Grant FA8655-06-1-3017-P00001 Registration of a Dynamic Multimodal Target Image Test Set for the Evaluation of Image Fusion Techniques

摘要

TNO has completed the construction of the TRICLOBS 3-band night vision system. This newly developed system consists of two digital image intensifiers (Photonis ICUs) and an uncooled longwave infrared microbolometer (XenICS Gobi 384). This night vision sensor suite registers the visual (400-700 nm), the near-infrared (700-1000 nm) and the longwave infrared bands of the electromagnetic spectrum. The optical axes of the three cameras are aligned, using two dichroic beam splitters (an ITO filter to reflect the LWIR part of the incoming radiation into the thermal camera, and a B43-958 hot mirror to split the transmitted radiation into a visual and NIR part). The field-of-view of the cameras is nearly the same, and any rotations between camera images has been be minimized. The registration of the individual images therefore requires only a minimal amount of computational effort. Software has been developed to register the signals from all 3 cameras simultaneously, display the images, and write them to a hard disk. The system was tested and multiband video was registered during a preliminary pilot field trial in a Dutch MOUT village. The imagery was used to make final adjustments to the camera system before registering imagery in the last phase of this project. The raw imagery has now been registered and fused into a false-color representation, suitable for input to sensor fusion algorithms.
