AI2-THOR: An Interactive 3D Environment for Visual AI

We introduce The House Of inteRactions (THOR), a framework for visual AI research, available at http://ai2thor.allenai.org. AI2-THOR consists of near photo-realistic 3D indoor scenes, where AI agents can navigate in the scenes and interact with objects to perform tasks. AI2-THOR enables research in many different domains including but not limited to deep reinforcement learning, imitation learning, learning by interaction, planning, visual question answering, unsupervised representation learning, object detection and segmentation, and learning models of cognition. The goal of AI2-THOR is to facilitate building visually intelligent models and push the research forward in this domain

3D Environment for Virtual Collections

This paper describes a framework for building virtual collections of several digital objects and presenting them in an interactive 3D environment, rendered in a web browser. Using that environment, the website visitor can examine a given collection from a first-person perspective by walking around and inspecting each object in detail by viewing it from any angle. The rendering and visualization of the models is done solely by the web browser with the use of HTML5 and the Three.js JavaScript library, without any additional requirements

Towards an Iterative Algorithm for the Optimal Boundary Coverage of a 3D Environment

This paper presents a new optimal algorithm for locating a set of sensors in 3D able to see the boundaries of a polyhedral environment. Our approach is iterative and is based on a lower bound on the sensors' number and on a restriction of the original problem requiring each face to be observed in its entirety by at least one sensor. The lower bound allows evaluating the quality of the solution obtained at each step, and halting the algorithm if the solution is satisfactory. The algorithm asymptotically converges to the optimal solution of the unrestricted problem if the faces are subdivided into smaller part

SMACS: Modelling Urban 3D Environment

La Universitat OsloMet té previst tancar el seu campus a Kjeller el 2023 per crear un nou campus a la regió de Romerike. Aquest canvi té per objectiu millorar i enfortir les sinergies entre la universitat i diferents empreses per tal de formar estudiants professionalment, així com per millorar la qualitat del campus en termes d’accessibilitat i ubicació, vida universitària i fins i tot ensenyament. Quatre estudiants de l’European Project Semester van tenir l’oportunitat de participar en aquest projecte i proposar una solució per dissenyar un potencial nou campus de la Universitat d’OsloMet basat en un anàlisi del flux de persones d'un edifici existent. Aquest informe mostra el camí seguit durant tot el semestre, des de la metodologia de treball, la investigació, la contextualització i anàlisi de la informació i les dades fins a la proposta final: la creació d’una eina que ajudi a prendre decisions sobre el disseny del nou campus per millorar el flux de persones i aprofitar tot l’espai disponible. S'ha desenvolupat una hipotètica proposta de com es podria distribuir el nou campus, que proporciona tres factors de flexibilitat en termes d'ubicació, nombre de persones i habitacions i versatilitat en l’ús dels espais disponibles. Per mostrar-ho d’una manera visual, s’ha dissenyat un model 3D que permet entrar a l’edifici i visualitzar com cada una de les plantes que formen el campus es distribueixen.La Universidad OsloMet tiene previsto cerrar su campus en Kjeller en 2023 para crear un nuevo campus en la región de Romerike.

A hypothetical proposal has been developed of how the new campus could be distributed, providing three factors of flexibility in terms of location, number of people and rooms and versatility in the use of the available spaces. To show this in a visual way, a 3D model has been designed that allows you to enter the building and visualise how each of the floors that make up the campus are distributed.Outgoin

3D environment mapping using the Kinect V2 and path planning based on RRT algorithms

This paper describes a 3D path planning system that is able to provide a solution trajectory for the automatic control of a robot. The proposed system uses a point cloud obtained from the robot workspace, with a Kinect V2 sensor to identify the interest regions and the obstacles of the environment. Our proposal includes a collision-free path planner based on the Rapidly-exploring Random Trees variant (RRT*), for a safe and optimal navigation of robots in 3D spaces. Results on RGB-D segmentation and recognition, point cloud processing, and comparisons between different RRT* algorithms, are presented.Peer ReviewedPostprint (published version
