摘要:For hundreds of years man had been trying to camouflage himself for some reasons. At first,the aim was to confuse potential victims when hunting. Later,camouflage was to ensure that one will disappear from their opponents’ view. With the invention of fire arms and the increasing distances over which battles were fought,the use of traditional uniforms in bright colors became less frequent,as they were replaced by such that imitated the surroundings. Spotting the opponent before they spotted you became the main priority on the battlefield. Nowadays,despite the abundance of different types of reconnaissance systems,camouflage is still very important. Only now,its range of applications has broadened. This range has long gone beyond the capabilities of the human eye. The use of near infrared,thermal vision or microwaves has set new challenges for camouflage designers. Spectral characteristics can be very helpful both for those creating new camouflage and those producing instruments able to detect camouflaged objects. The reflectance characteristics are the spectral equivalent of the human fingerprint. Each object has its unique spectral characteristic. The differences in these characteristics for different objects can be enough to distinguish them from one another. A method for extracting camouflaged objects based on their spectral characteristics obtained using remote sensing methods has been described in this article. In order to complete this task,a series of multi- and hyperspectral images had been acquired in the laboratories of the Remote Sensing and Photogrammetry Department of the military University of Technology. Next,based on these images,reflectance characteristics were obtained. These spectral characteristics were then verified and analyzed. A comparative analysis of the characteristics obtained for chosen natural objects assist in selecting the optimal spectral bands in which the contrast between the camouflage and its background will be greatest. Such bands were then used in the visual analysis of camouflage.
