Omnidirectional Cameras Calibration and Stereo 3D Reconstruction

by Baisheng Lai for Open Source Computer Vision Library (OpenCV)

Omnidirectional cameras consist of fish eye and catadioptric ones, while Opencv now can only calibrate fish-eye. A calibration tool based on C Mei's unified model [1] which can calibration all omnidirectional cameras will be implemented. The conventional stereo rectify gets perspective images and need very large images to contain all details. I will use a longitude-latitude mapping [2] which can preserve all details while not increasing image size. Stereo matching can still be applied in a line.
