Abstract In mountain tunnels’ mechanical and electrical engineering, it is necessary to carry out cable distribution plates. To ensure the accuracy of plate, essential measure distance between box hole tunnel mouth size hole. Stereo matching a crucial step in using binocular vision for measurement, quality effect directly affects measurement following steps. This study focuses on studies stereo...

The images taken by the Heliospheric Imagers (HIs), part of the SECCHI imaging package onboard the pair of STEREO spacecraft, provide information on the radial and latitudinal evolution of the plasma compressed inside corotating interaction regions (CIRs). A plasma density wave imaged by the HI instrument onboard STEREO-B was found to propagate towards STEREO-A, enabling a comparison between si...

The High Resolution Fly’s Eye (HiRes) Experiment has been in operation in monocular mode since 1997 and in stereo mode since late 1999. The published HiRes monocular spectrum is consistent with the GZK Suppression at 10 eV and observes an ankle structure at 10 eV. The preliminary stereo spectrum is consistent with the monocular spectrum. Various anisotropy studies with both monocular and stereo...

We present a novel combination photometric stereo which can estimate surface normals precisely even for images including shadows and specular reflection. We can use photometric stereo if there are more than three input images. Therefore we can employ photometric stereo with nC3 combinations for n input images. We make 3D distribution of albedos and surface normals estimated from pixel intensiti...

Conventional photometric stereo has a fundamental limitation that the scale of recovered geometry is limited to the resolution of the input images. However, surfaces that contain sub-pixel geometric structures are not well modelled by a single normal direction per pixel. In this work, we propose a technique for resolution-enhanced photometric stereo, in which surface geometry is computed at a r...

In the present study, the effects of arrangement and distribution of multifarious types of defects on fundamental frequency of carbon nanotubes are investigated with respect to different chirality and boundary conditions. Interatomic interactions between each pair of carbon atoms are modeled using two types of non–linear spring–like elements. To obtain more information about the influences of d...

Forage fish and associated with particular benthic habitats (e.g., rockfishes, sand eels, lances) may be particularly difficult to assess through standard survey methodologies. Stereo-cameras, video, automated visual data serve as useful complementary tools provide insight into the dynamics of these species. Visual methods used not only estimate abundance distribution, but also inform important...
