calib - Calibration algorithm

NAME

calib

SYNOPSIS

calib [ -f filename ] [ -i filename ] [ -o filename ] [ -u float ] [ -a integer ] [ -b integer ] [ -c integer ] [ -d integer ] [ -s integer ] [ -p float ]

DESCRIPTION

calib is a calibration routine for estimating the intrinsic and extrinsic parameters of a camera. It accepts two kinds of input. The first kind of input is the data file describing the correspondence between reference 3D points and their image coordinates. The second kind of input is an image in .pgm format and in square size. For further information about the .pgm data see the .pgm man pages. Output of this routine is a text file describing the estimated intrinsic and extrinsic parameters including focal length, rotation matrix and translation vector between the world coordinate system and the camera coordinate system.

OPTIONS

-f filename
input filename (the file describes the correspondence between reference 3D points and their image coordinates)
-i filename
input filename (the file is in .pgm format)
-o filename
output filename
-u float

-a integer
minimum of x coordinate for the region containing the 16 squares
-b integer
maximum of x coordinate for the region containing the 16 squares
-c integer
minimum of y coordinate for the region containing the 16 squares
-d integer
maximum of y coordinate for the region containing the 16 squares
-s integer
image size [default 512]
-p float
pixel size [default 0.008]
