Augmented reality systems for weed economic thresholds applications

The augmented reality (AR) technology has applications in many fields as diverse as aeronautics, tourism, medicine, and education. In this review are summarized the current status of AR and it is proposed a new application of it in weed science. The basic algorithmic elements for AR implementation are already available to develop applications in the area of weed economic thresholds. These include algorithms for image recognition to identify and quantify weeds by species and software for herbicide selection based on weed density. Likewise, all hardware necessary for AR implementation in weed science are available at an affordable price for the user. Thus, the authors propose weed science can take a leading role integrating AR systems into weed economic thresholds software, thus, providing better opportunities for science and computer-based weed control decisions.

Augmented reality in sport scenarios using cameras mounted on a tripod

[ES] In this paper we address the problem of inserting virtual content in a video sequence. The method we propose uses just image information. We perform primitive tracking, camera calibration, real and virtual camera synchronisation and finally rendering to insert the virtual content in the real video sequence. To simplify the calibration step we assume that cameras are mounted on a tripod (which is a common situation in practise). The primitive tracking procedure, which uses lines and circles as primitives, is performed by means of a CART (Classification and Regression Tree). Finally, the virtual and real camera synchronisation and rendering is performed using functions of OpenGL (Open Graphic Library). We have applied the method proposed to sport event scenarios, specifically, soccer matches. In order to illustrate its performance, it has been applied to real HD (High Definition) video sequences. The quality of the proposed method is validated by inserting virtual elements in such HD video sequence.

Realtà Aumentata applicata alla manutenzione tecnica di macchinari industriali

La tesi, svolta per il completamento della Laurea Magistrale in Ingegneria Informatica, tratta la realizzazione di un progetto prototipo di Computer Vision (CV) e Realtà Aumentata (RA) per la manutenzione tecnica di macchinari industriali attraverso l'utilizzo di dispositivi mobili See-Through. Lo scopo è stato, oltre lo studio dello stato dell'arte in materia, provare con mano e rendere maggiormente visibili al pubblico questi nuovi rami dell'informatica. Il prototipo creato è stato inserito in un contesto aziendale, con misurazioni e prove sul campo. Partendo da una breve introduzione sulla realtà aumentata, nel primo capitolo viene descritto il progetto sviluppato, diviso in due sottoprogetti. Il primo, svolto solamente in una fase iniziale e presentato nel secondo capitolo, espone la realizzazione di un'applicazione mobile per lo streaming video con l'aggiunta di contenuti grafici aumentati. Il secondo, progettato e sviluppato in totale autonomia, rappresenta un prototipo demo di utilizzo della RA. La realizzazione viene illustrata nei capitoli successivi. Nel terzo capitolo si introducono gli strumenti che sono stati utilizzati per lo sviluppo dell'applicazione, in particolare Unity (per il development multi-piattaforma), Vuforia (per gli algoritmi di CV) e Blender (per la realizzazione di procedure di manutenzione). Il quarto capitolo, la parte più rilevante della trattazione, descrive, passo dopo passo, la creazione dei vari componenti, riassumendo in modo conciso e attraverso l'uso di figure i punti cardine. Infine, il quinto capitolo conclude il percorso realizzato presentando i risultati raggiunti e lasciando spunto per possibili miglioramenti ed aggiunte.

MHP Oriented Interactive Augmented Reality System for Sports Broadcasting Environments

Television and movie images have been altered ever since it was technically possible. Nowadays embedding advertisements, or incorporating text and graphics in TV scenes, are common practice, but they can not be considered as integrated part of the scene. The introduction of new services for interactive augmented television is discussed in this paper. We analyse the main aspects related with the whole chain of augmented reality production. Interactivity is one of the most important added values of the digital television: This paper aims to break the model where all TV viewers receive the same final image. Thus, we introduce and discuss the new concept of interactive augmented television, i. e. real time composition of video and computer graphics - e.g. a real scene and freely selectable images or spatial rendered objects - edited and customized by the end user within the context of the user's set top box and TV receiver.

Entwicklung eines Funktionsumfangs für Augmented Reality Führungen in Hochschulbibliotheken

Anwendungen in Bibliotheken auf Basis von Augmented Reality (AR), der Erweiterung der Realität durch zusätzliche, virtuelle Informationen, existieren bislang nur vereinzelt. Das vom Bundesministerium für Wirtschaft und Energie geförderte Forschungsprojekt mylibrARy ermittelt seit Juni 2014 Szenarien für den Einsatz von AR in Bibliotheken und Informationseinrichtungen. Das Projekt zielt auf die Entwicklung einer deutschlandweit einsetzbaren Applikation (App). An diesen Gedanken knüpft die vorliegende Arbeit mit der Entwicklung eines Konzepts für Einführungen in Hochschulbibliotheken mittels AR-Technik. Aus der Analyse aktueller Führungsmodelle von Bibliotheken der Hochschulen im Exzellenzcluster 2012-2017, werden die für die Modellführung benötigten charakteristischen Merkmale einer Bibliotheksführung abgeleitet. Auf die technisch relevanten Grundlagen der AR folgt eine Bestandsaufnahme der bisherigen Augmented-Reality-Projekte im internationalen Bibliothekskontext. Daran schließt die Formulierung der theoretischen Anforderungen und die Ausarbeitung der Funktionen im Einzelnen. Nachfolgend lenkt eine kritische Betrachtung den Fokus auf Mehrwert und Risiken der AR für Bibliothek und Nutzer. Mit einer Zusammenfassung und dem Ausblick auf die zukünftige Entwicklung findet die Arbeit ihren Abschuss.

Sviluppo di un’app mobile con Realtà Aumentata e Machine Learning in contesto di biodiversità

Il volume di tesi ha riguardato lo sviluppo di un'applicazione mobile che sfrutta la Realtà Aumentata e il Machine Learning nel contesto della biodiversità. Nello specifico si è realizzato un modello di AI che permetta la classificazione di immagini di fiori. Tale modello è stato poi integrato in Android, al fine della realizzazione di un'app che riesca a riconoscere specifiche specie di fiori, oltre a individuare gli insetti impollinatori attratti da essi e rappresentarli in Realtà Aumentata.

Enhanced switchgear connection testing through augmented reality: early developments

Augmented reality is an emerging field of interactive design in which virtual material is seamlessly blended with displays of real world environments. The tremendous potential of augmented reality has begun to be explored with the emergence of personal mobile devices capable of constructing engaging augmented reality experiences. This work is part of a project aiming at using augmented reality goggles to bring advance information to the user interacting with switch-gear during automation cabling. In particular we will be focusing on the recognition and definition of the figures of the component on the AR device. In this part we are using standard camera that allows us to get real images and helps us to localize the gearbox in space through ARUCO marker and we can exploit in order to re-project the actual shape of the component that are currently interested in manipulation by exploiting the data provided by the database. The experiments are carried out using the camera to get the images of the real world switch-gear and re-project those images with the component superimposed on it. Using transforms of the database we did localization to re-project the rendered image of component exactly on the real world component, which can be further integrated in AR goggles to see the component superimposed in real-time.

Augmented Reality for Games

In this text, we intend to explore augmented reality as a means to visualise interactive communication projects. With ARToolkit, Virtools and 3ds Max applications, we aim to show how to create a portable interactive platform that resorts to the environment and markers for constructing the game’s scenario. We plan to show that the realism of simulation, together with the merger of artificial objects with the real world, can generate interactive empathy between players and their avatars.
