Multiview stereo (MVS) is a crucial process in image-based automatic 3-D reconstruction and mapping applications. In a dense matching process, the matching cost is generally computed between image pairs, making the efficiency low due to the large number of stereo pairs. This paper presents a novel object-based MVS algorithm using structural similarity (SSIM) index matching cost in a coarse-to-fine...
The use of smartphones for activities like watching movies and playing games has become commonplace because of the flexibility that devices offer citizens in their increasingly overloaded daily routines. As a consequence, the market has explored the creation of accessories to enhance the user experience in performing these tasks. The present work selected as context the practice of watching movies...
We present RDCL 3D, a “model agnostic” web framework for the design and composition of NFV services and components. The framework allows editing and validating the descriptors of services and components both textually and graphically and supports the interaction with external orchestrators or with deployment and execution environments. RDCL 3D is open source and designed with a modular approach, allowing...
The results of the inclusion of Virtual Reality in the production line of an Industry Joalheira in the state of Bahia, a case study which was conducted in the elevenmonth period by a Startup consisting of two professional Designers and one Information Technology, between the years of 2008 and 2009. The production flow of this jewelery factory was losses due to continuous communication difficulties...
This work aims to present a methodology of communication between a criminal database and a virtual environment for forensic study, using a proprietary software and a virtual reality prototype, in order to support forensic science activities. The objective is to assist the forensic professional offering the use of criminal investigation resources inside a crime scene simulation, with sensations of...
In the context of visualization and interaction with molecules, the representation of a 3D virtual environment potentially helps the understanding of data and structure manipulation that, in other case, would demand too much effort to be interpreted in a conventional way. Additionally, the exploration of these 3D environments in an immersive way may also improve the usability regarding velocity, precision...
Consumer-grade RGB-D cameras capture RGB images along with per-pixel depth information, and because of their limited cost and ability to measure distances at a high frame rate, have been used in robotics and computer vision application. However, drawbacks include the repeatability and accuracy of RGB-D cameras for object detection and localization. This paper investigates and compares RGB-D cameras'...
In the modern industry, human-robot collaboration is becoming more and more important. With the quick development of the small production, the demand of flexibility is growing heavily. Gesture recognition is important for the collaborative work of humans and robots. In industrial applications, the performance of such systems affects the safety of human workers and their manufacturing efficiency. In...
The technology of 2D GM-SYS gravity-magnetic inversion improved the reliability of geological sections, but the result of inversion can’t be imported into the GoCAD software to build the 3D geological model directly. A software, named G2G, is developed based on the file formats of GM-SYS and GoCAD, to transfer the GM-SYS inversion sections into GoCAD software format’s files, improving the efficiency...
By using a virtual campus, users can not only immerse in the campus scene, but also interact with the system, which helps them understand the campus rapidly and deeply. But the virtual campus itself doesn't provide the relevant data information of the campus scene, which severely limits its application to a certain extent. To solve this problem, oriented to Beijing Institute of Petrochemical Technology...
La lechería es muy importante para la economía uruguaya, por esta razón, interesa realizar investigaciones en esta área. Este trabajo comprendió la incorporación de tecnologías en sistemas lecheros para realizar estimaciones de disponibilidad de forraje. Particularmente, se estimó la disponibilidad de forraje en un potrero mediante el procesamiento de imágenes georeferenciadas de las pasturas, las...
Modeling with 3D computer-aided design (CAD) software to design and print 3D products can improve students' spatial visualization skills, creativity, and problem solving skills. 3D CAD software has been used as a teaching tool in secondary school classrooms since the early 2000s, but it becoming more ubiquitous due to increased affordability of an innovative concept: 3D printing. Yet research about...
One of the most important factors in teamwork is the integration of the people who compose it because is strongly linked to the level of cohesion and team performance. Therefore the activities to integrate it are very important because they allow building and strengthening both the personal and professional relationships among the team members. Nowadays there is a great variety of activities to carry...
With the advance of mobile technologies, virtual reality (VR) is coming to every corner of our life. The technology presents a major opportunity for retailers as they lure fickle shoppers to visit their virtual stores, particularly since modern consumers have shifted more of their buying habits online. Currently, merchants face the challenge to weed out malicious software from legitimate users to...
According to the theory of cylinder indexing cam mechanism, based on the modular design, the CAD/CAM system of cylinder indexing cam mechanism is developed by VB6.0 and Creo3.0. This system is a visual interface which is build by VB6.0and it can be used to output the three-dimensional coordinate data and processing date of the cylinder indexing cam through the basic parameters input of cam and the...
Combined with popular Internet of things and virtual reality technology, this paper has developed a set of intelligent agriculture, intelligent home in one of the intelligent manor sand table demo system. System test shows that the system can effectively simulate a number of intelligent agriculture, intelligent home in the practical scene. In the intelligent agricultural system part of the use of...
3D printing is a revolutionary technology, it allows to reproduce pieces of very diverse nature. That is very useful for a wide spectrum of professionals, artists and entrepreneurs. The training and teaching of these technologies represents a great challenge. It implies to satisfy the expectations of a great variety of people with different interests of use. In this article, the Teaching for Understanding...
One of the biggest benefits of virtual education is the ability to easily explain complex processes and principles using animations and interactive 3D models. The purpose of this study is to determine which 3D software product should be used for the display of interactive graphic engineering documents, so that the visualization and manipulation of 3D models provide useful support to students of industrial...
This paper is focused on a complex robotic process called bin-picking. It is a very known and well-researched topic in the field of robotic manipulation where the robot is expected to grasp non-oriented objects from a bin and placed them to locations within the following process flow. Although we present here a functional case study of a bin-picking system based on a modified revolving vision system,...
This paper presents the application outcomes of a three-dimensional virtual environment which simulates a farm, called Fazenda 3D, in the Technical Course on Agriculture and Farming of the Federal Institute of Education, Science and Technology of Amazonas, at Parintins city. The purpose of the software is to support the technical subjects studies of the course. In order to evaluate the software we...
