int arParamChangeSize	(	ARParam *	source,
		int	xsize,
		int	ysize,
		ARParam *	newparam
	)

change the camera size parameters.

Change the size variable in camera intrinsic parameters.

Parameters:

source	name of the source parameters structure
xsize	new length size
ysize	new height size
newparam	name of the destination parameters structure.

Returns:: 0

int arParamDecomp	(	ARParam *	source,
		ARParam *	icpara,
		double	trans[3][4]
	)

XXXBK.

XXXBK

Parameters:

source	XXXBK
icpara	XXXBK
trans	XXXBK

Returns:: XXXBK

int arParamDecompMat	(	double	source[3][4],
		double	cpara[3][4],
		double	trans[3][4]
	)

XXXBK.

XXXBK

Parameters:

source	input camera matrix
cpara	camera parameter to be set
trans	XXXBK

Returns:: XXXBK

Definition at line 35 of file lib/SRC/AR/paramDecomp.c.

int arParamDisp ( ARParam * param )

display parameters.

Display the structure of the camera instrinsic parameters argument.

Parameters:

param structure to display

Returns:: 0

		double	screen[][2],
		int	data_num,

int int arParamIdeal2Observ	(	const double	dist_factor[4],
		const double	ix,
		const double	iy,
		double *	ox,
		double *	oy
	)

Convert ideal screen coordinates of a vertex to observed ones.

Ideal coordinates mean that the distortion of the camera is compensated (so a straight line looks straight). In observed coordinates the camera-distortion is not compensated and thus a straight line is not shown really straight.

Parameters:

dist_factor	distorsion factors of used camera
ix	x in ideal screen coordinates
iy	y in ideal screen coordinates
ox	resulted x in observed screen coordinates
oy	resulted y in observed screen coordinates

Returns:: 0 if success, -1 otherwise

Definition at line 53 of file lib/SRC/AR/paramDistortion.c.

int arParamLoad	(	const char *	filename,
		int	num,
		ARParam *	param,
			...
	)

load the camera intrinsic parameters.

Load camera intrinsic parameters in the ARToolkit Library from a file (itself, an output of the calibration step).

Parameters:

filename	name of the parameters file.
num	number of variable arguments
param	result of the loaded parameters

Returns:: 0 if success, -1 if Error (file not found, file structure problem)

Definition at line 152 of file lib/SRC/AR/paramFile.c.

int arParamObserv2Ideal	(	const double	dist_factor[4],
		const double	ox,
		const double	oy,
		double *	ix,
		double *	iy
	)

Convert observed screen coordinates of a vertex to ideal ones.

Ideal coordinates mean that the distortion of the camera is compensated (so a straight line looks straight). In observed coordinates the camera-distortion is not compensated and thus a straight line is not shown really straight.

Parameters:

dist_factor	distorsion factors of used camera
ox	x in observed screen coordinates
oy	y in observed screen coordinates
ix	resulted x in ideal screen coordinates
iy	resulted y in ideal screen coordinates

Returns:: 0 if success, -1 otherwise

Definition at line 18 of file lib/SRC/AR/paramDistortion.c.

int arParamSave	(	char *	filename,
		int	num,
		ARParam *	param,
			...
	)

save a camera intrinsic parameters.

Save manipulated camera intrinsic parameters in a file.

Parameters:

filename	name of the parameters file.
num	number of variable arguments
param	parameters to save

Returns:: 0 if success, -1 if Error (file not found, file structure problem)
