Fisheye Lenses Calibration Using Straight-Line Spherical Perspective Projection Constraint
Fisheye lenses are often used to enlarge the field of view (FOV) of a conventional camera. But the images taken with fisheye lenses have severe distortions. This paper proposes a...

Automatic 3D Model Construction for Turn-Table Sequences
As virtual worlds demand ever more realistic 3D models, attention is being focussed on systems that can acquire graphical models from real objects. This paper describes a system wh...

Using Points at Infinity for Parameter Decoupling in Camera Calibration
We consider the problem of decoupling translation and rotation for a collection of 3D data related to 2D images by a projection. The main contribution is to show that equations de...

Paracatadioptric Camera Calibration Using Lines
Paracatadioptric sensors combine a parabolic shaped mirror and a camera inducing an orthographic projection. Such a configuration provides a wide field of view while keeping a s...

Calibrating Freely Moving Cameras
We present a novel practical method for self-calibrating a camera which may move freely in space while changing it internal parameters by zooming. We show that point correspondenc...
