Target identification with improved color rendering steps

Enhanced LADAR imaging with the use of a synthetic comparative model

Photonics

The inclusion of color and texture are two key attributes traditionally associated with superior target identification techniques. These have been employed in various camouflage designs wherein very slight changes in color or print can mean the difference between being seen or not seen.

Common remote sensing technologies – specifically LADAR – struggle in discerning color and texture at a distance.  This invention from Navy researchers aims to advance the state-of-the-art in remote sensing with enhanced color rendering steps from an optical sensor working alongside a LADAR sensor.  The technology pushes intensity imagery (an optical to electronic signal converter) through a MACH filter and then overlays that onto to a 3D wiregrid model.  The wiregrid model is built up from a multitude of sensor data of the target of interest. Users input the likely classification of the target (i.e. a ship), and the database begins its image comparison against stored images of ships.  Intensity data is used to compare a synthetic image with the observed image on a pixel-by-pixel and average pixel intensity basis.
