In this paper, aiming at the problem of imprecise localization and perturbation interference in the field of traditional large screen, large screen interactive system with projection technology is designed based on the affine transformation algorithm to realize the precise interactive region coordinate positioning. Any wall touch system of human-computer interaction has been obtained by the analysis...
Augmented Reality (AR) merges real and virtual objects in order to make a richer environment with additional useful virtual information. Producing AR maintenance training depends on two major points that will be Interactivity and Reusability. Recently Augmented Reality becomes the new technology revolution in software applications such as (entertainment, training, military, E-shops and games), and...
Intrinsic image decomposition is an important technique that decomposes an image into reflectance and shading components. In this paper, we enable intrinsic decomposition for stereoscopic images. Traditional approaches cannot be directly applied to decompose stereoscopic images, yielding inconsistent reflectance and 3D artifacts after recoloring. To solve this problem, we propose a straight yet effective...
The ability to open a door is essential for robots to perform home-serving and rescuing tasks. A substantial problem is to obtain the necessary parameters such as the width of the door and the length of the handle. Many researchers utilize computer vision techniques to extract the parameters automatically which lead to fine but not very stable results because of the complexity of the environment....
One of the important goals in Human Computer Interaction (HCI) is designing better and more intuitive interfaces for improving the interactions. There are lots of approaches to address this problem. One of these approaches is utilizing human hand gestures. The degree of freedom and complex structure of human hand however, make capturing and modeling of hand gestures a challenging problem. In this...
Due to the gradient-free mechanism, flexibility, high local optima avoidance, and simplicity, meta-heuristics have been reliable alternatives to conventional optimisation techniques over the course of last two decades. This has resulted in the application of such techniques in diverse branches of science and technology. Despite all the successful applications, meta-heuristics are less effective in...
To solve the problem of rapid perception of the collected content and non-contact measurement in integral imaging, computer virtual reconstruction algorithm of a three dimensional scene is proposed. Firstly, calculate the combined disparity map of an elemental image array using the region-based iterative matching algorithm according to the distribution characteristics of the homologous pixels in the...
This paper presents a robust and important method for the self-calibration of a numerical camera using a tridimensional unknown scene. The particularity of our technique resides in the use of an arc of the circle and the localization of some of the matching points detected in the use of an ensemble of images in order to define in an automated way the intrinsic parameters, which are unknown and variable...
An increasingly large amount of multimodal content is posted on social media websites such as YouTube and Face book every day. In order to cope with the growth of such so much multimodal data, there is very urgent need to develop an intelligent multi-modal analysis framework that can effectively extract information from multiple modalities. In this research work, here propose a novel multimodal information...
Development of computer technology today has a major role in the development process of interaction in computer-based applications. Various innovations in creating the user experience of applications began are increasing. Augmented reality is a technology model the interaction between humans and computers by using a model of a merger between the real world with the virtual world. This development...
The main goal of this work is to introduce sensor technologies that have an impact on modern world. There are many technologies and many different views on them. Current trends lead the entire world to work on various combinations of several technologies. This allows us to look at the world through a camera in a wide spectrum at the same time. Using IR sensor, depth camera is eligible to scan one's...
Autonomous vehicles are an emerging application of automotive technology. They can recognize the scene, plan the path, and control the motion by themselves while interacting with drivers. Although they receive considerable attention, components of autonomous vehicles are not accessible to the public but instead are developed as proprietary assets. To facilitate the development of autonomous vehicles,...
We developed a software system for operating the humanoid robot DRC-HUBO+ in disaster circumstances that the US Defense Advanced Research Projects Agency suggested. This system was developed under the consideration of the stability of whole system, the systemic software environment for multiple developers, and the recovery routine when the system encounters a seriously abnormal situation. With these...
Due to the improvements in computer technology, interaction between computer and human has been evolved from command-line based interfaces to natural user interfaces that enables interaction in a more human-human way such as by speech, hand and body gestures, facial expressions and eye gaze. In this study controlling three dimensional images with gestures and speech using a three dimensional depth...
Live Scan3D is a free, open source system for live, 3D data acquisition using multiple Kinect v2 sensors. It allows the user to place any number of sensors in any physical configuration and start gathering data at real time speed. The freedom of placing the sensors in any configuration allows for many possible acquisition scenarios such as: capturing a single object from many viewpoints or creating...
This paper describes the development of a test bed for an on-drone computation system, in which the drone plays the game of ping-pong competitively (YCCD: The Yorktown Cognitive Competition Drone). Unlike other drone systems and demonstrators YCCD will be completely autonomous with no external support from cameras, servers, GPS etc. YCCD will have ultra-low power computation capabilities including...
Camera calibration is a fundamental problem in computer vision community. Already extensive research has been conducted and emerge a large number of excellent calibration algorithm, but there is few studies of automatic calibration system, the camera calibration toolbox for the moment almost use multi-use manual or semi-automatic marking the target area and extracting feature points, inefficient and...
Vibrant lighting of relief maps via high-resolution dynamic projected imagery can be a powerful tool for simulation, augmented reality, and visualization, enabling several scientific, educational and entertainment applications. This is usually achieved via multiple projectors lighting the relief map, which are then sensed by multiple cameras for geometric and color calibration. However, cumbersome...
Micro aerial vehicles, such as multirotors, are particular well suited for the autonomous monitoring, inspection, and surveillance of buildings, e.g., for maintenance in industrial plants. Key prerequisites for the fully autonomous operation of micro aerial vehicles in complex 3D environments include real-time state estimation, obstacle detection, mapping, and navigation planning. In this paper, we...
This paper introduces the 5* Magic Wand: a user interface that provides an inexpensive way for input of 3D data. Drawing upon the metaphor of the "wizard", a user can point to places, perform gestures and cast "spells" to interact with the computer. We describe a computer vision technique that tracks the wand with 5 degrees of freedom. A prototype implementation, composed of a...
