METHODOLOGY FOR USING VIDEO CAMERAS IN FOREST MAPPING

Abstract

The scope of this paper is the methodological development of an imaging system, which uses conventional video cameras and spectral filters (green, red, and near infrared) as non- conventional sensor. The sensor has the purpose of forest mapping. For that purpose, a spectral study of each filter was carried out as well as a study of filters' behavior in different types of targets. As a result, it is highlight the importance of obtaining images in almost real time, low operational costs, practicality and operationality of the system, as well as the agility to obtain images.As disadvantages, the system shows the overlaping of the filters' spectral behavior and the low spatial resolution of VHS cameras. Both of these factors can be solved by using other types of filters with different wavelengths and by using S-VHS cameras.
