|Title:||Development Of A New Method For Volume Measurement Based On Moiré Techniques [desenvolvimento De Um Novo Método Para Medida De Volume Baseado Em Técnicas De Moiré]|
de Almeida C.
|Abstract:||This research work reports a shadow moiré method applied in generating spatial dimensions of solid figures. The focus of this work is to study as well as to turn feasible a new method of measuring object shape as plant organs. Selected experimental setup included four Ronchi optical grids out of phase by 1/4 of period, a conventional white light source and a digital camera. The samples were hold by a support, following by data acquisition process generating four elevation digital models (EDM). EDM were employed to create the tridimensional Model (TM) which, in turn, was also applied to generate the object volume. The method of water volume displacement has been used for data comparison in which the change of liquid volume is equal to the object volume. The results allowed to state that moiré techniques can be used for volumetric determination of irregular objects as fruits and others vegetable organs. The work includes error determination.|
