Heterogeneous devices with large displays have become popular in people lives. While conveying public information, most of them are lack of support for human interaction. This paper proposes a cross device interaction system for users to conveniently manipulate the content on public displays through personal mobile terminals with cameras. Users acquire, insert, and act on elements of the displayed...
Augmented Reality (AR) applications on mobile devices like smartphones and tablet computers have become increasingly popular. In this paper, for the first time in the AR domain, we present: (1) the influence of different handheld displays and (2) the exocentric depth perception. Unlike egocentric depth perception, exocentric depth perception has not been investigated in AR.
We propose a fast and efficient method for localization and rectification of a dominant rectangular region within an image, particularly suitable for mobile Augmented Reality applications. This approach can deal with perspective distortion and high-frequency structures such as text. The resulting image may be used for planar tracking or as input for subsequent image processing tasks. We demonstrate...
By the image processing and pattern recognition technology, the average background method and the Hausdorff distance method was used to video frames captured by the wireless mobile camera installed on the head of underground mine locomotive, mobile target was tracked in real-time to achieve the locomotive forward, backward and stop, judge its running track and location, calculate the recent short-range...
Recent mobile device and vision technology advances have enabled mobile Augmented Reality (AR) to be serviced in real-time using natural features. However, in viewing augmented reality while moving about, the user is always encountering new and diverse target objects in different locations. Whether the AR system is scalable or not to the number of target objects is an important issue for future mobile...
In this paper, a new mobile Augmented Reality (AR) framework which is scalable to the number of objects being augmented is proposed. The scalability is achieved by a visual word recognition module on the remote server and a mobile phone which detects, tracks, and augments target objects with the received information from the server. The server and the mobile phone are connected through a conventional...
To date, robots are expected to work in human environment. However, symbiotic robots need advanced abilities. In this research, we pay attention to ??movement ability?? and ??recognition ability??. We chose two-wheeled mobile manipulator with a monocular camera. Therefore, the purpose is to achieve both the target tracking and the attitude stabilization. Firstly, the new visual servoing is proposed...
This paper presents the un-calibrated vision servo control algorithm to track the target with mobile manipulator. Color histogram distance calculation methods and shape matching method are discussed to recognize the target .The on-line estimation algorithm for Image Jacobian matrix model is designed based on the Kalman filter. With this image Jacobian on-line estimator, the visual feedback controller...
Today's automotive sensor systems for in-vehicle based target tracking, i.e. radar, lidar, camera, are limited to a field of view which is restricted by distance, angle and line-of-sight. Future driver assistance systems such as predictive collision avoidance or situation-aware adaptive cruise control require a more complete and accurate situation awareness in order to detect hazardous and inefficient...
We review some recent techniques for 3D tracking and occlusion handling for computer vision-based augmented reality. We discuss what their limits for real applications are, and why object recognition techniques are certainly the key to further improvements.
