چکیده

We describe the principles of a device comprised of a static camera and rotating plane mirror that enables the passive recovery of 3D range information. The range recovery can be regarded as either structure from known motion or as virtual multi-camera stereo. Two advantages of the arrangement are that the camera-mirror system is compact and that range information can be recovered over a wide, near panoramic, field of view.

Recovering Range Using Virtual Multicamera Stereo

This paper describes and demonstrates a novel method for the passive recovery of depth from a rotating linescan camera, giving information over a full field of view. The recovery method can be regarded as either structure from known motion or as multi-camera stereo. Also described are the principles of a device comprising of a static camera and rotating plane mirror that enables the same method...

A Video-rate Stereo Machine and Its Application to Virtual Reality

We have developed a video-rate stereo machine which has the capability of generating a dense range map at video rate. The CMU video-rate stereo machine has the following performance: 1) multi image input of up to 6 cameras; 2) throughput of 30 million point × disparity measurements per second; 3) frame rate of 30 frames/sec; 4) a dense depth map of 256 × 240 pixels; 5) disparity search range of...

High Accuracy Depth Measurement using Multi-view Stereo

A novel scheme for depth extraction is achieved using a multiple view ring camera system. The ring camera method captures a series of images of scene from a set of camera locations arranged in a circular ring. Tracking of scene features through this sequence realizes circular feature trajectories. The recovery of depth can be obtained with this method by determining the diameter of the circular...

Interactive Augmentation of Live Images using a HDR Stereo Camera

Adding virtual objects to real environments plays an important role in todays computer graphics: Typical examples are virtual furniture in a real room and virtual characters in real movies. For a believable appearance, consistent lighting of the virtual objects is required. We present an augmented reality system that displays virtual objects with consistent illumination and shadows in the image...

Robust visual tracking using a fixed multi-camera system

The problem of tracking the position and orientation of a moving object using a stereo camera system is considered in this paper. A robust algorithm based on the extended Kalman filter is adopted, combined with an efficient selection technique of the object image features, based on Binary Space Partitioning tree geometric models. An experimental study is carried nut using a vision system of two...
