MOSIS - Multi-Outcrop Sharing & Interpretation System

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.

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.

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.
