Abstract:
Virtual Reality (VR) is based on the use of sensors, and the customization of its use for agricultural analysis is still a challenge. This study presents a solution for the analysis of agricultural soils based on sensor devices, signal conditioning, X-ray tomographic images, and a VR interface. In such a context, tomographic images from soil samples can be submitted though a user interface to a process of manipulation and volumetric visualization based on graphic-computational resources which add functionalities like immersion for the user’s interaction with the samples. Validation was based on a case study involving the analysis of the porosity of agricultural soils samples in which preferential paths for water flow were reconstructed and manipulated by VR interaction techniques. In fact, by using 59.6 keV of energy and a time window of 10 seconds for sampling of each tomographic projection, it was possible to reconstruct digital tomographic images from agricultural soils to be analyzed using such a system. Results indicated both a new and non-invasive way for the evaluation of the spatial organization and physical properties of agricultural soils and its potential use for food production.
