Resumo: 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.

O presente trabalho apresenta o desenvolvimento metodológico de um sistema imageador, utilizando câmaras de vídeo convencionais e filtros espectrais (verde, vermelho e infravermelho próximo) como sensor não-convencional. Esse sensor possui como finalidade realizar mapeamento de áreas florestais. Para tal finalidade, foi realizado um estudo do espectro de cada filtro utilizado bem como o comportamento por ele apresentado nos diversos tipos de alvos. Como resultados, salienta-se  a importância da obtenção das imagens quase que em tempo real, custos operacionais baixos, praticidade e operacionalidade do sistema bem como a agilidade de obtenção das imagens, e como desvantagem apresenta o comportamento espectral dos filtros utilizados se sobreporem e a baixa resolução espacial das câmaras VHS, aspectos esses que podem ser solucionados utilizando-se outros tipos de filtros nos mais diversos comprimentos de onda, e a utilização de câmaras S-VHS.Universidade Federal de Santa Maria2001-06-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsm.br/cienciaflorestal/article/view/165210.5902/198050981652Ciência Florestal; Vol. 11 No. 2 (2001); 27-39Ciência Florestal; v. 11 n. 2 (2001); 27-391980-50980103-9954reponame:Ciência Florestal (Online)instname:Universidade Federal de Santa Maria (UFSM)instacron:UFSMporhttps://periodicos.ufsm.br/cienciaflorestal/article/view/1652/938Watzlawick, Luciano FarinhaMadruga, Pedro Roberto de AzambujaPereira, Rudiney Soaresinfo:eu-repo/semantics/openAccess2017-06-05T19:09:37Zoai:ojs.pkp.sfu.ca:article/1652Revistahttp://www.ufsm.br/cienciaflorestal/ONGhttps://old.scielo.br/oai/scielo-oai.php||cienciaflorestal@ufsm.br|| cienciaflorestal@gmail.com|| cf@smail.ufsm.br1980-50980103-9954opendoar:2017-06-05T19:09:37Ciência Florestal (Online) - Universidade Federal de Santa Maria (UFSM)false
