ICARUS is a suite of software packages designed to enable the calibration of image and video sequences, and the reconstruction of geometric models of real scenes from those sequences. The best: its FREE (for not commercial purposes). Get it at: http://aig.cs.man.ac.uk/icarus/

More info about ICARUS:

The current version of the software (v2.01) comes as three separate components:

a.. Lens Distortion Removal
Geometric lens distortion may be estimated and removed from images or video sequences, using simple interactive techniques. No calibration grids are required, and video and image sequences may be undistorted and saved back to disk.

b.. Image and Video Sequence Calibration
Intrinsic and extrinsic camera parameters (e.g. camera position, orientation, focal length etc..) may be estimated using automatic and semi-automatic approaches.

Features:
a.. Matchmoving for free-movement and pan/tilt/zoom camera motions
b.. Automatic and semi-automatic feature tracking
c.. Manual motion-tweaking facilities
d.. Cineon image file support
e.. 2D and 3D tracking export (Lightwave, Maya, Houdini, Combustion and Flame/Inferno)
f.. Garbage matte support, including keyframing and automatic tracking
g.. Automatic mosaic generation
h.. Motion segmentation to remove moving objects from panning video sequences
i.. 2D and 3D video sequence stabilization

c.. Geometry Reconstruction
ICARUS supports digital video (DV) format (using AVI files), as well as any codecs provided by DirectShow (DirectX 8.1). It also supports many standard image formats (TIFF,BMP,GIF,JPEG etc...) as well as the Cineon image format (FIDO and DPX files).

The video sequence calibration software may be used independently of the other components for automatic camera tracking or matchmoving (Lightwave/Maya/Houdini/Combustion/Flame/Inferno exports available). This provides the capability to augment images or video sequences with synthetic objects. ICARUS is also be capable of tracking film-resolution sequences, although this feature has not been properly tested as we do not have any real footage to test the software with.
