ABSTRACT:
The present invention relates to an apparatus for locating objects (such as exploded or unexploded ordnance). The embodiments take advantage of spectroscopic features of an object's paint or surface finish to discriminate between the object and the background area. The apparatus utilizes an optical sensor, filters and the application of pixel to pixel ratios to detect the paint on an object from a distance so that objects such as unexploded ordnance may be safely destroyed or neutralized.
