2004: Development and application of an extended geometric model for high resolution panoramic cameras
"... Digital panoramic photography has become a popular tool to record landscapes, city squares or indoor scenes in a single image with a full 360 ° view. In photogrammetric applications, a digital panoramic camera may present an interesting alternative to conventional image acquisition techniques such a ..."

cameras and the mathematical model depict a very suitable tool for precise 3D modelling of indoor scenes, city squares or long façades in combination with the analysis of very high resolution texture information. The paper concentrates on results of a self-calibrating bundle adjustment using the developed
Real-time omnidirectional and panoramic stereo
- In Proceedings of the 1998 DARPA Image Understanding Workshop
, 1998
"... Traditional stereo systems have a small field of view which limits their usefulness for certain applications. By imaging curved mirrors, the field of view of conventional cameras can be enhanced. In this paper, we present the design of a compact panoramic stereo camera which uses parabolic mirrors a ..."

A Hemispherical Imaging Camera
- N, CAMERA NETWORKS, AND NON-CONVENTIONAL CAMERAS A HEMISPHERICAL IMAGING CAMERA
, 2009
"... Most of the existing panoramic cameras have cylindrical field of view (FOV) which has a 360 ° width in azimuth, but a limited height in elevation. However, a hemispherical (or near spherical) FOV is highly desirable in many applications such as robot navigation and surveillance. This paper presents ..."

a planar-mirror-based panoramic camera (HEM) which is capable of acquiring nearly hemispherical FOV panoramic images at high and substantially uniform resolution, from a single viewpoint, at video rates. The camera consists of multiple imaging sensors and a hexagonal prism made of planar mirror
In \Panoramic Imaging: Sensors, Theory, and Applications, " Ed. by Benosman and Kang. Single Viewpoint Catadioptric Cameras
"... Conventional video cameras have limited elds of view which make them restrictive for certain applications in computational vision. A catadioptric camera uses a combination of lenses and mirrors placed in a carefully arranged con guration to capture a much wider eld of view. One important design goal ..."

High-Resolution X-ray Imaging Based on Curved Bragg Mirrors: First Results
"... Abstract—Small animal cancer imaging has drawn increased attention over the last few years due to greater availability of genetically modified mice, permitting the study of human diseases in animal models. Submillimeter resolution would be of great value to provide the fine detail needed in the imag ..."

resolution devices, are fundamental in nature. They include image blurring through edge effects, scattering at the pinhole, and inelastic Compton scattering. Furthermore, such devices often yield low efficiency. In this paper, a new approach to high-resolution imaging of radio-labeled agents is introduced
A New Class of Mirrors for Wide-Angle Imaging
"... Conventional mirrors for panoramic imaging usually capture circular images. As these images are difficult to interpret visually, they are often remapped digitally into a rectangular image in which one axis represents azimuth and the other elevation. This paper describes a class of mirrors that perfo ..."

that perform the capture as well as the remapping, thus eliminating the need for computational resources. They provide uniform resolution in azimuth and elevation, and can be designed to make full use of a camera’s imaging surface.
2005: Combined bundle adjustment of panoramic and central perspective images
- XXXVI, Part 5/W8
"... Based on a strict mathematical model for rotating line cameras developed at the Institute of Photogrammetry and Remote Sensing of the Dresden University of Technology, a self-calibrating bundle adjustment of panoramic image data was implemented. This model has been extended by the option to involve ..."

central perspective images of a conventional camera. A panoramic bundle adjustment is a suitable tool for precise 3D modelling of indoor scenes or city squares in combination with the analysis of very high resolution texture information, as only a few panoramas are necessary for stereo capture of 360

- Individual Soldier,” Military Communications Conference 2005 (MILCOM 2005
, 2005
"... Laser radar (LADAR) has many advantages over other methods of target detection and analysis, both in combat and commercial applications. Because it uses a shorter wavelength than microwave radar and has significantly greater angular resolution, it is capable of a greater degree of accuracy and more ..."

, with conventional digital zoom, a portion of an image is used to create a larger but much lower resolution image, while the LADAR zoom technology discussed in this paper will have a tighter field of view for a high resolution zoom image. Other innovation is a relatively inexpensive and compact laser driver that can

In this paper, we provide algorithms and geometries providing optimal mirror placements for two natural classes of problems; object-independent and object-dependent mirror placement. In the object-independent formulation, we seek to design ..."
