Temporal stereo vision algorithms can offer improved robustness, however, this can only be delivered after several frames of a stereo image sequence have been processed. We present a new method of bootstrapping temporal stereo which can overcome such start-up problems by applying additional coarse-to-fine pre-processing to the first few images in a stereo sequence. To gauge the performance of t...

Mapping of the Earth’s surface from satellite images is a continuing application in remote sensing, which has been distinctly pushed with the increasing availability of very high-resolution image data. In most of the missions, stereo images can be acquired making 3D mapping from space very attractive, as high accuracy and level of detail become feasible from such data. In this paper, several ca...

This paper proposes a novel hardware implementation of a dense recovery of stereovision 3D measurements. Traditionally 3D stereo systems have imposed the maximum number of stereo correspondences, introducing a large restriction on artificial vision algorithms. The proposed system-on-chip (SoC) provides great performance and efficiency, with a scalable architecture available for many different s...

This paper introduces a novel stereo vision based simulation system for a Humanoid Robot. This stereo vision system and robot controller is simulated dynamically and its performance evaluated for a standard humanoid robot benchmark problem. The vision system presented has been tested by simulating the dynamics of the robot system as well as the image processing subsystem. The real-time image pr...

In this paper the role of object identification in sanification system for Navigation Assistance Visually Impaired (NAVI) is discussed. The developed system includes Single Board Processing System (SBPS), vision sensor mounted headgear and stereo earphones. The vision sensor captures the vision information in front of blind user. The captured image is processed to identify the object in the ima...

To date, orbital and ground image data have been mostly separately processed for topographic mapping in Mars landed missions. We are in the process of developing a method for the integration of orbital and ground image networks to enhance precision mapping. In this research, HiRISE stereo images were used as orbital data while ground data include MER-B Pancam stereo images and their pointing in...

Stereo vision systems have been researched for decades and constitute the traditional method for extracting three-dimensional (3D) real-time depth information from images using sensors. However, passive stereo vision systems show a significant error in processing untextured regions, which are frequent in indoor environments. Also, modifications for processing in real time make error by using ap...

In this paper, a tele-operated gesture recognition mobile robot using a stereo vision is represented. We propose a real-time face and hand classification and 3D position extraction using a stereo vision embedded system. To obtain the disparity image, we used the stereo vision process on FPGA and developed the embedded system to obtain the image sequence for basic image processing. Then we appli...

This report presents stereo image theory and the corresponding image processing software developed to analyze stereo imaging data acquired for the wake-vortex hazard ight experiment conducted at NASA Langley Research Center. In this experiment, a leading Lockheed C-130 was equipped with wing-tip smokers to visualize its wing vortices, while a trailing Boeing 737 ew into the wake vortices of the...
