Relativistic Panorama

In freshman general physics, the professor briefly touched Einstein’s relativity and pointed out that if there were a fat person walking at the speed of light, he would look as thin as a piece of paper! This effect is called Lorenz contraction. The reason is roughly that the time and space is mixed at high speed and that we can “see” time as a negative spatial length. Hence we want to see some ...

Panorama Sketching for PDAs

We present a sketch-based system for creating and modifying 3D scenes on mobile devices (PDAs). The user models the scene by sketching a panoramic image. The process of 2D sketching is aided by underlying simplified 3D model of the scene. The 3D model provides additional information to the system, allowing 3D-like transformations of the scene objects and automatic shading. The user either creat...

Generating Panorama Photos

Photo or video mosaicing have drawn a lot of interests in the research field in the past years. Most of the existing work, however, focuses on how to match the images or video frames. This paper presents techniques to handle some practical issues when generating panorama photos. We have found from the experiments that a simple translational motion model gives more robust results than affine mod...

Panorama-based Camera Calibration

This paper presents a method to calibrate a camera from panoramas. Camera calibration using panoramas has two main advantages: on the one hand it requires neither ground control points or calibration patterns and on the other hand the estimation of intrinsic and distortion parameters is of higher quality due to the loop constraint and to a decorrelation of tied parameters due to the fixed persp...
