Abstract
A novel indirect building localization technique based on a prominent solid
landmark from a forward-looking infrared imagery is proposed to localize low, deeply
buried, or carefully camouflaged buildings in dense urban areas. First, the widely
used effective methods are applied to detect and localize the solid landmark. The
building target is then precisely indirectly localized by perspective transformation
according to the imaging parameters and the space constraint relations between the
building target and the solid landmark. Experimental results demonstrate this
technique can indirectly localize buildings in dense urban areas effectively.
