A catadioptric stereo system has been developed for depth perception. The system uses two sets of planar mirrors to create two virtual cameras. A design procedure is presented with the aim of building a compact assembly. This has resulted in an inexpensive and compact system that achieves a depth resolution of 5.8 cm at a working distance of 2 m.

We propose a framework for depth estimation from a set of calibrated images, captured with a moving camera with varying parameters. Our framework respects the physical limits of the camera, and considers various effects such as motion parallax, defocus blur, zooming and occlusions which are often unavoidable. In fact, the stereo [1] and the depth from defocus [2] are essentially special cases i...

In this paper we present a new calibration approach for focused plenoptic cameras. We derive a new mathematical projection model of a focused plenoptic camera which considers lateral as well as depth distortion. Therefore, we derive a new depth distortion model directly from the theory of depth estimation in a focused plenoptic camera. In total the model consists of five intrinsic parameters, t...

This work achieves an efficient acquisition of scenes and their depths along long streets. A camera is mounted on a vehicle moving along a path and a sampling line properly set in the camera frame scans the 1D scene continuously to form a 2D route panorama. This paper extends a method to estimate depth from the camera path by analyzing the stationary blur in the route panorama. The temporal sta...

The usable perceived depth range of all stereoscopic 3D displays is limited by human factors considerations to a bounded range around the plane of the display. To account for this our Three Region stereoscopic camera model is able to control the depth mapping from scene to display while allowing a defined region of interest in scene depth to have an improved perceived depth representation compa...

This paper describes Deep Window, an implementation of a mobile window into a virtual world using a depth camera. Deep Window explores the use of 2.5D depth cameras to implement 3D interaction techniques. Users can move and orient a tablet to change their perspective of a 3D scene, showing that it is possible for a 3D interaction technique to be replicated with a depth camera. A user study comp...
