Optical-digital complex for detection of remote mines and mapping of minefields

Abstract

The article is dedicated to a new method of detecting masked ground and subsurface objects for mapping of minefields and engineering reconnaissance. We proposed to use stereoscopic hyperspectral IR remote sensing in order to increase the reliability of detecting and reducing the frequency of false alarms. Stereoscopic surveying allows exclude skipping of objects masked in vegetation and laid at an angle, and separate the disturbed surface (friable signs) from ordinary soil and embankments. The results of processing hyperspectral data from two channels are combined into a thematic thermal stereomodel of the terrain, on which the anomalies found by the algorithm are highlighted. The concept of an optical-electronic complex of remote sensing of minefields, structural and optical schemes, applied calculations and design solutions are presented in the first part of article. We described basic algorithms for processing hyperspectral data, the method of combining them into a thermal stereomodel of the terrain with the possibility of classifying objects and cross-linking with a three-dimensional map of the area in the second part of the article.
