This paper describes two fast range sensing systems that are being developed at the RobottcS Institute of Carnegie MelIon. The first system is a passive video-rate stereo machine, based on the multi-baseline stereo theory, whose expected performance will exceed that of existing stereo methods or mediumto-short distance scanninglaser range Ande rsin most categories: high throughput (l.% Million ...

Fast depth estimation from binocular vision is often desired for autonomous vehicles, but, most algorithms could not easily be put into practice because of the much time cost. We present an image-processing technique that can fast estimate depth image from binocular vision images. By finding out the lines which present the best matched area in the disparity space image, the depth can be estimat...

as the information carried in a high spatial resolution image is not represented by single pixels but by meaningful image objects, which include the association of multiple pixels and their mutual relations, the object based method has become one of the most commonly used strategies for the processing of high resolution imagery. this processing comprises two fundamental and critical steps towar...

In 3D TV applications, the extraction of 3D representations of dynamic scenes from images plays a central role in the preparation of the presented visual content. This paper focuses on the stereo cue to the extraction of these representations and, in particular, on the recently developed family of volumetric approaches to stereo. Two methods are proposed that improve the accuracy of volumetric ...

Panoramas and object movies are popular image-based techniques for modeling and rendering 3D scenes and objects. In this paper, we present a method which allows the authors of virtual exhibition systems to produce an augmented stereo panorama by interactively integrating stereo object movies into a stereo panorama. When navigating in the augmented stereo panorama with a stereoscopic display, th...

ISPRS and CNES announced the HRS (High Resolution Stereo) Scientific Assessment Program during the ISPRS Commission I Symposium in Denver in November 2002. 9 test areas throughout the world have been selected for this program. For the Barcelona test site not only two-fold stereo HRS data but also HRG data of the same region have been acquired. This leads to the possibility to compare the DEM pr...

In this paper, a high dynamic range (HDR) imaging method based on the stereo vision system is presented. The proposed method uses differently exposed low dynamic range (LDR) images captured from a stereo camera. The stereo LDR images are first converted to initial stereo HDR images using the inverse camera response function estimated from the LDR images. However, due to the limited dynamic rang...

We investigate the stereo matching techniques for high dynamic range (HDR) image pairs. It is an emerging topic in computer vision and multimedia applications due to the availability of HDR image capture devices. The disparity computation will eventually take the stereo HDR input. In this work, three state-of-the-art stereo matching algorithms are modified and used to test the advantages of HDR...

Introduction: The Mars Orbital Laser Altimeter (MOLA) has significantly advanced the study of the Martian surface by providing geologists with a highly accurate elevation map of the entire planet [1]. However, its limited resolution (463m/pixel at the equator) and localized interpolation artifacts have rendered it insufficient for detailed studies of specific sites; e.g. geologic stratification...
