In this paper, a novel algorithm for creating virtual indoor environments is described. First, a panoramic mosaic is generated from a series of photos taken with a camera rotates along a horizontal axis. Then, from the panoramic mosaic image, a non-fixed viewing point virtual walkthrough system can be created by defining manually the corners in the vertical panoramic mosaic. The side ratio of t...

This article presents a simple technique for splitting up a panoramic range image into a set of 2[1/2]D representations. The proposed technique consists of three stages. First, a spherical discretization map is generated. Second, main surface orientations are extracted together with their corresponding histogram of distances. Each one of these histograms is used to define the position of a proj...

We present an algorithm for infinitesimal motion estimation from multiple central panoramic views. We first derive the optical flow equations for central panoramic cameras as a function of both pixel coordinates and back-projection rays. We then derive a rank constraint on the optical flows across many frames, which must lie in a six dimensional subspace of a higher-dimensional space. We then p...

Building I This work tackles route understanding in robot navigation. The strategies employed are route description from experience and route recognition by visual information. In description phase, a new representation of scenes along a route termed Panoramic Representation is proposed. It is obtained by scanning scenes sideways along the route, which provides rich information such as a 2D pro...

This paper surveys state of the art image features and descriptors for the task of 3D scan registration based on panoramic reflectance images. As modern terrestrial laser scanners digitize their environment in a spherical way, the sphere has to be projected to a two-dimensional image. To this end, we evaluate the equirectangular, the cylindrical, the Mercator, the rectilinear, the Pannini, the ...

The fusion of panoramic camera data with laser scanner data is a new approach and allows the combination of high-resolution image and depth data. Application areas are city modelling, virtual reality and documentation of the cultural heritage. Panoramic recording of image data is realized by a CCD-line, which is precisely rotated around the projection centre. In the case of other possible movem...

The purpose of this paper was to review the rationale for the radiographic screening of asymptomatic pediatric patients and to report the prevalence of selected pathologic and developmental conditions using panoramic radiographs. Three observers participated in this retrospective study that utilized panoramic radiographs from 849 subjects, aged 3-9 years, chosen randomly from the School of Dent...

As the eld of view of a picture is much smaller than our own visual eld of view, it is common to paste together several pictures to create a panoramic mosaic having a larger eld of view. While scissors and glue are the tools used in lm photography, more sophisticated methods were enabled with digital video. Panoramic mosaics can be created by special devices which rotate around the camera's opt...
