Projects

VISCARB
Modelling and management of multiscale data, 3-D visualization and outcrops interpretations sharing.
The project has the central purpose of developing a Digital Interactive Geological Atlas with 3D visualization of analogs in varying scales and a supportive toolset for interpretation (Unisinos) and multiscale modeling (LNCC). The results from the project will subsidize the understanding of fracturing and karstification of carbonate reservoirs, as well as helping in the construction of more realistic geological models through the incorporation of parameters extracted from subsurface data, and also propound techniques of geological modeling that take in account those new models.
This study fits in an arrangement of joint work composed by different projects from Petrobras which will provide data and information for the Atlas. Those are the results of geological mapping through virtual outcrops models, shallow geophysics with different techniques for obtaining subsurface data, in addition to laboratory data such as petrography, geochemistry, microscopy, petrophysics, porous systems, hydromechanical/geomechanical analysis, among others. Those projects and the respective executors intitutions are CristalDOM (UFRN), CarbLab (UFG), FurnaDOM (UFRN), Queijo Suíço (UnB), and VISCARB (Unisinos). Other projects related to studies of fractured and karstified carbonate rocks might associate to this arrangement during the execution, both as data providers and system users.

MOSIS - Multi-Outcrop Sharing & Interpretation System
Fully immersive computational environment capable of creating the awareness of being on the fieldwork, while also providing the user with an extensive toolset for DOMs interpretation.
Throughout the last few years, the number of studies on virtual outcrops surface models, acquired by LiDAR and multi-view SfM techniques has been increasing dramatically. Due to the large quantity of data generated by these methods the geoscientists now have access to an ever-increasing data set. However, these researchers have no available software capable of offering a user experience comparable to the fieldwork. Though interpretation software packages have been developed, they are inherently limited by the characteristics of 2-D displays. The visualization environment suffers from a lack of immersion to emulate the fieldwork experience.
Some tools that try to achieve this have been developed, but, while succeeding to deliver the necessary immersion, they fall short on the interpretation toolset area. That is what lead to the development of MOSIS, a system that provides a fully immersive computational environment capable of creating the awareness of being on the fieldwork, yet also providing the user with an extensive toolset for DOMs interpretation. This complete system will help to reduce uncertainties in Oil&Gas exploration and production. It can support the development of more robust conceptual geological models, through analyzing the quantitative and qualitative geological parameters of analogs.

RIDerS
Low cost immersive driving simulator to improve the teaching & training learning process of the Transport Infrastructure.
The principal goal of this project is to develop a low-cost immersive driving simulator to improve the teaching & training learning process of the Transport Infrastructure. The driving simulator has been developed in a virtual reality environment to assist both the teaching of engineering and the research on road safety through a fully immersive environment by eliminating external distractions.

ImSpector
Virtual reality system for inspection of road and viaducts.
One of the main difficulties in the inspection of bridges or viaducts by observation is inaccessibility or lack of access throughout the structure. As mapping from remote sensors on unmanned aerial vehicles (UAVs) or laser scanning becomes more common, it also presents an interesting alternative to the engineer as it enables more detailed analysis and diagnostics.
Such mapping techniques also allow the generation of realistic 3D models that can be integrated into Virtual Reality (VR) environments. In this sense, the ImSpector presents a system that uses realistic 3D models generated by remote sensors embedded in UAVs. That way it is capable of implementing a virtual and immersive environment for inspections. As a result, it provides to the engineer a tool to carry out field tests directly at the office, ensuring agility, accuracy, and safety in bridge and viaduct inspections.

AVenCer
Game focused on the study of upper limb members affected in a Stroke.
It is a game aimed at physiotherapeutic rehabilitation of patients with sequelae in the upper limb affected by Stroke. The experience occurs in non-immersive virtual reality with the addition of the hardware Leap Motion. The project is based on fitting visually distinct geometric figures on their respective sockets along four challenges.
Those steps distribute the objects, in order, between:
- Static and aligned
- Static and misaligned with different heights
- Static and diagonals with different heights
- Dynamic objects with physics
The user is encouraged to perform flexo-extension movements of the shoulder, elbow, wrist, and fingers so that the objectives can be accomplished. This type of exercise helps the patient as it works with fine motor skills. The game has an opening panel for collecting personal information, the kind and etiology of the stroke that occurred and the range of disability. The generated data can be exported for external analysis, which leads to conclusions on the evolution of the patient.

Medviewer
Telediagnosis, dysmorphology analysis and monitoring of patients with congenital anomalies and rare genetical disorders.
This work presents a visualization system of 3D models for telediagnosis of dysmorphic syndromes and rare diseases. The system includes diagnostic support tools such as immersive visualization and metric analysis, as well as a client-server architecture for storing and distributing models. In order for them to be accessed on different devices, the models need to be available in different resolutions and, for this, it is needed simplification and their quality verification.
In order to measure the aforementioned quality, a method of comparing point clouds based on the approximation of subsets of the cloud to the planes is being developed. A prototype of the system has been developed and has already presented good results, which include immersion support and tools to perform measurements in the virtual model. The comparison method has been tested during its development and presents promising results.
