METHOD OF FAST AND ROBUST CAMERA LOCATION ORDERING

摘要

A method to estimate a set of camera locations, in clockwise or counter-clockwise order, according to the videos captured by these cameras is described herein. In some embodiments, the cameras are assumed to be fixed, with no or very mild tilting angles and no rolling angles (the horizon is horizontal in each camera image). The difference of orientation (rolling angle) between each neighboring (closest) camera pair is able to be up to 45 degrees. Each camera is assumed to have overlapped views with at least one other camera. Each camera has one right neighboring camera and one left neighboring camera, except the first and the last cameras which have only one neighboring camera at one side. The locations of the cameras then are able to be expressed as a unique list counter-clockwise. The input videos are assumed to be synchronized in time.
