It is estimated that the number of devices connected to the Internet will be 50 billion by 2020. How should a not-so-tech-savvy end-user be able to discover, configure, and directly interact with a myriad of connected things in an intuitive and comfortable manner? Even if smartphones and wearables have shown potential for managing IoT environments, we cannot rely on that they can be used for all future...
Digitisation of natural history collections not only preserves precious information about biological diversity, it also enables us to share, analyse, annotate and compare specimens to gain new insights. High-resolution, full-colour 3D capture of biological specimens yields color and geometry information complementary to other techniques (e.g., 2D capture, electron scanning and micro computed tomography)...
Urban environment constitutes a challenging area for pedestrian navigation. However, with the recent increase of pedestrians owning devices (e.g. smartphones), complementary data provided by integrated low cost sensors (camera, Inertial and Magnetic Measurement Unit and GNSS receiver) may be used in a coupling process to accurately estimate the pose (i.e. 3D position and 3D orientation) of a handheld...
Markerless Augmented Reality (AR) registration using the standard Homography matrix is unstable, and for image-based registration it has very low accuracy. In this paper, we present a new method to improve the stability and the accuracy of marker-less registration in AR. Based on the Visual Simultaneous Localization and Mapping (V-SLAM) framework, our method adds a three-dimensional dense cloud processing...
Microbial science is inevitably involved in human daily life because these creatures live around us. They are both useful and punishable. If the people have knowledge about microorganisms, it can control the microbes that cause the wicked things, and it can also be useful to use microorganisms effectively. Currently, the study still use the microscope in the education. There are limitations when exploring...
Augmented reality has seen a fast-growing gain of interest in the last few decades. Due to technological advances, smartphones are now devices that allow to experience augmented reality systems, anytime and anywhere. Although its emerging success among users, some problems AR have been reported inhibiting its full acceptance in our digital society. The aim of this paper is to present a study about...
The concept of Augmented Reality is a technology in which the interaction between the human-computer that can generate two-dimensional or three dimensional object in real time. Augmented reality can provide the necessary functions and information in its application. In this case the augmented reality (AR) just need a tool like a camera that can capture images by detecting the object without the marker...
Augmented reality (AR) allows to seamlessly insert virtual objects in an image sequence. In order to accomplish this goal, it is important that synthetic elements are rendered and aligned in the scene in an accurate and visually acceptable way. The solution of this problem can be related to a pose estimation or, equivalently, a camera localization process. This paper aims at presenting a brief but...
In recent papers, the concept of an intelligent window for machine tools (iWindow) using virtual and augmented reality in order to replace traditional windows in machine tools was introduced. Such intelligent windows provide additional possibilities for observing the machine interior under difficult visibility conditions, combine and reduce the number of supporting systems and enrich the machine interior...
Discrepancy check is a well-known task in industrial Augmented Reality (AR). In this paper we present a new approach consisting of three main contributions: First, we propose a new two-step depth mapping algorithm for RGB-D cameras, which fuses depth images with given camera pose in real-time into a consistent 3D model. In a rigorous evaluation with two public benchmarks we show that our mapping outperforms...
The Extended TV application allows to enhance an audiovisual content displayed on a TV, using Mixed Reality technology. During preprocessing, the close environment of the TV is scanned using a consumer depth camera. The captured RGB-D data are analyzed, providing models for both the 3D geometry and the lighting of the real scene. During runtime, the TV is watched through a tablet, and virtual objects...
In this demo, we present RKSLAM, a robust keyframe-based monocular SLAM system that can reliably handle fast motion with strong rotation and ensure good AR experiences. We contribute two key technical contributions: a novel multi-homography based feature tracking method which is very robust and efficient, and a sliding-window based camera pose optimization scheme which imposes the motion prior constraints...
Indirect augmented reality (IAR) presents pre-generated augmented images for achieving high-quality geometric and photometric registration between pre-captured images and virtual objects. Meanwhile, IAR causes spatial inconsistency between the real world and presented images when users move from the location where the real scene was captured. This paper describes a novel way to address the spatial...
Augmented Reality furniture arrangement systems are useful for viewing room or building layouts without having to buy or move real furniture. However, such systems often require users to physically and frequently change their viewpoint of the physical space, which requires manual manipulation of the scene, and are often limited to 2D tablet or phone interfaces. To help address this problem, we have...
Localizing the user from a feature database of a scene is a basic and necessary step for presentation of localized augmented reality (AR) content. Commonly such database depicts a single appearance of the scene, due to time and effort required to prepare it. To account for appearance changes under different lighting we propose to generate the feature database from a simulated appearance of the scene...
3D visualization of breast tumors are shown to be effective by previous studies. In this paper, we introduce a new augmented reality application that can help doctors and surgeons to have a more accurate visualization of breast tumors; this system uses a marker-based image-processing technique to render a 3D model of the tumors on the body. The model can be created using a combination of breast 3D...
This paper discusses a system based on Augmented Reality for Home Exhibition, which supports real-time tracking without Identification Markers, the system uses FAST corner detection and local window matching algorithm to establish the initial 3D maps. It then uses OpenGL ES Graphics Rendering Tools to make the virtual furniture models which established by MAYA on the mobile phone based on the real-time...
This paper presents an Augmented Interactive Reality book (AIR) application, aimed to enhance the reading experience of adult-learners by incorporating Augmented Reality (AR) technology to improve the interaction of normal books. Various features and characteristics of Augmented Reality (AR) were applied to the chosen book, "My Vision" written by H.H. Sheikh Mohammed Bin Rashid Al Maktoum,...
Correct spatial alignment is an essential requirement for convincing augmented reality experiences. Registration error, caused by a variety of systematic, environmental, and user influences decreases the realism and utility of head mounted display AR applications. Focus is often given to rigorous calibration and prediction methods seeking to entirely remove misalignment error between virtual and real...
The light field, or plenoptic function, is a mathematical construct that models the location and direction of light to describe the complete visual appearance of a scene. The light field provides a unifying construct to describe cameras and displays. Explicitly manipulating the light field is an approach to changing the world to make it easier to understand. One way to create light fields is with...
