Determinação de propriedades geométricas e físicas para criação de um modelo digital tridimensional do sistema fruta-galho de laranjeiras

Abstract

Oranges are the most widely produced and consumed fruit in the world, with juice being the main form of consumption. Rich in nutrients, especially due to their high vitamin C content, much of their sales are exported on a large scale, which increases their consumption in other countries. This study aimed to determine the physical and geometric properties of the orange fruitbranch system to generate a three-dimensional digital model. Orange samples were collected and specimens of the fruits and branches were selected. The specimens were subjected to measurements of different diameters related to geometric properties, and of mass, volume and density as physical properties. The process was carried out in the immature and mature stages, and thus it was possible to determine average values for the model to be developed. The measured diameters did not show significant changes for the branches, unlike the orange fruits that presented different values at different stages of ripeness. This study emphasizes the importance of analyzing branches and fruits at different stages of ripeness to obtain coherent data. The methodology allowed the collection of information on diameter, mass, volume and density, resulting in a database for future research. From this data, a simplified three-dimensional digital model for the fruit-branch system of orange trees was created.
