Paper Abstract

Industrial maintenance is one of the main branches of infrared thermology applications. Our main studies are also concentrated on real time applications e.g., quality control automation. Environmental control is the branch which is strongly increasing. Plant damage is one of the most interesting things. The temperature changes is one feature which gives information about damage. At the beginning the necessary laboratory tests were done to study the possibilities of infrared monitoring of nature. After the preliminary tests the systematical studies were carried out. Using systematical measurements with infrared camera including image processing on plant leaves the clear changes were seen as a function of time. The studies were done applying the measurements on the fresh plant leaves. Later on the leaves were damaged by cutting and again monitored by infrared. After filtering and profile analysis the systematical changes were detected which show the changes of plant physiology after damage. The analysis of the above studies are given in this paper.
