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'...
Traditional image editing techniques cannot be directly used to process stereoscopic media, as extra constraints are required to ensure consistent changes between the left and right images. In this paper, we propose a hybrid warping model for stereoscopic image stitching by combining projective and content-preserving warping. First, a uniform homography algorithm is proposed to prewarp the left and...
The rapid and ever growing development of Information and Communication Technologies (ICT) have made possible for virtual laboratories to be used as an alternative or to supplement the physical laboratories. Physical laboratories found at high school, colleges and universities occupy physical space, require a lot of maintenance and also require an expertise to work and function properly. All of the...
The term Conformal Printing refers to 3D printing onto uneven surfaces. Whilst some very high priced solutions exist for known uneven surfaces, where the toolpath is generated in advance, based on CAD data of the object to be printed onto, there is nothing available yet for conformal printing onto unknown uneven surfaces that are scanned on-the-fly. A low-cost prototype named ‘InSPIREd’ was recently...
This paper presents the work performed in the implementation of an underwater simulation environment for the development of an autonomous underwater vehicle for the exploration of flooded underground tunnels. In particular, the implementation of a laser based structured light system, multibeam sonar and other robot details were addressed. The simulation was used as a relevant tool in order to study...
Commercially available depth sensing devices are primarily designed for domains that are either macroscopic, or static. We develop a solution for fast microscale 3D reconstruction, using off-the-shelf components. By the addition of lenses, precise calibration of camera internals and positioning, and development of bespoke software, we turn an infrared depth sensor designed for human-scale motion and...
Immersive technologies such as 360° cameras and head-mounted displays (HMDs) have become affordable to the average consumer, opening up new audiences for storytellers. However, existing immersive post-production software often requires too great a technical or financial investment for smaller creative shops, including most of the country's newspapers and local broadcast journalism organizations. Game...
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...
A workflow is proposed for Cultural Heritage applications in which the fusion of 3D and 2D visual data is required. Using data acquired by cheap, standard devices, like a 3D scanner having a low quality 2D camera in it, and a high resolution DSLR camera, one can produce high quality color calibrated 3D model for documenting purpose. The proposed processing workflow combines a novel region based calibration...
Articulated arm robots have become critical components in the modern manufacturing environment, effectively performing a diverse range of manufacturing tasks. Robots offer flexibility through re-programmability — however, robot programming remains a time consuming task which requires highly skilled operators. Aiming to reduce the required time and complexity of robot programming, this paper presents...
The current paper presents the Quiz Cube application and its evaluation. The Quiz Cube application is an AR mobile learning application for students and teachers to easily make and use AR UI system using fiducial marker cubes. AR as a platform is just now reaching its full potential. Since smartphones and mobile devices are now at a sufficiently large user base, it is worth looking at the potential...
Natural or man-made disasters often result in trapped victims under rubble piles. In such emergency response situations, Urban Search and Rescue (USaR) teams have to make quick decisions to determine the location of possible trapped humans. The fast 3D modelling of collapsed buildings using images from Unmanned Aerial Vehicles (UAVs) can significantly help the USaR operations and improve disaster...
Indonesia is an archipelago country with various kind of arts and cultures that must be maintained and preserved. Traditional dance is one kind of arts and cultures owned by each territory in Indonesia. Optical motion capture computer technology had been successfully implemented as traditional dance motion captured. Using this technology, traditional dancer movement could be documented and stored...
Processing of a vast number of aerial images from high-resolution digital camera always leads to the use of lengthy hours. This contradicts to the advantage of the use of UAV that could acquire and deliver the data rapidly to highlight the actual condition of the terrain. In previous studies, 1033 images were used covering the size of about seven kilometres square of the study area. During image acquisition...
In the paper, we describe the extensions of the 3D-HEVC compression technology aimed at improved compression efficiency for multiview sequences acquired from arbitrarily located cameras. Our proposal refines the inter-view prediction by replacing the horizontal shifts with the true mapping in the 3D space. This implies changes in several coding tools, which we describe in details. The paper also reports...
Given a series of overlapped images, it is possible to reconstruct camera position and orientation, as well as 3D coordinates of object in the images. Such method is known as Structure from Motion (SfM), which is currently implemented in various commercial and open source software. The first software commonly don't provide Sfm algorithm. While the latter software are commonly developed partially....
The study of historical monument needs a great care especially for the old object. Along with current technologies, allowing the object studied scanned in three dimensions. To make the objective achieved, the digital form of objects studied has almost become mandatory for simplicity of study and also variety of analysis. For various scale of objects that present everywhere, hardware and software equipment...
The paper presents an analysis of a rowing technique and the participant's fatigue based on the handle's trajectory. The rowing was recorded with the use of Vicon motion capture. Seven non-rowers were participants in the research. 42 strokes were analysed in three phases of rowing. Two theses: (i) “handle trajectory indicates the fatigue while rowing” and (ii) “the rowing technique may be assessed...
The objective of this paper has been the development of a prototype of articulated robotic arm and the implementation of a control strategy through gesture recognition (Leap Motion Sensor), by means the natural movement of the forearm and hand. The series of advances relative to the control techniques have caused that the robotics it has also introduced as an educational complement in obligatory basic...
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,...
