Abstract
Fisheye cameras are special cameras that have a much larger field of view
compared to conventional cameras. The large field of view comes at a price of non-linear
distortions introduced near the boundaries of the images captured by such cameras.
Despite this drawback, they are being used increasingly in many applications of computer
vision, robotics, reconnaissance, astrophotography, surveillance and automotive
applications. The images captured from such cameras can be corrected for their distortion
if the cameras are calibrated and the distortion function is determined. Calibration also
allows fisheye cameras to be used in tasks involving metric scene measurement, metric
scene reconstruction and other simultaneous localization and mapping (SLAM)
algorithms. The fisheye camera is considered a central omnidirectional cameras and in
recent years many different methods to calibrate central omnidirectional cameras have
been developed, based on the type of camera model. This thesis presents a calibration
toolbox that implements a collection of some of the most widely used techniques for
calibration of fisheye cameras under one package. This enables an inexperienced user to
calibrate his/her own camera without the need for a theoretical understanding about
computer vision and camera calibration. This thesis also explores some of the
applications of calibration such as distortion correction and 3D reconstruction.
