Function Documentation

◆ arParamClear()

int arParamClear	(	ARParam *	param,
		int	xsize,
		int	ysize,
		int	dist_function_version
	)

Create a camera parameter structure representing an idealised lens.

This function creates a camera parameter structure representing an idealised lens, that is, a lens with a symmetrical perspective projection and no distortion. This idealised lens is useful in cases where you wish to match the lens model of an OpenGL camera with the same window dimensions.

Parameters

param	Pointer to an ARParam structure which will be filled out with the resulting camera parameters.
xsize	The horizontal dimension of the image.
ysize	The vertical dimension of the image.
dist_function_version	Allows creation of parameters with an older version of the lens distortion model. Pass AR_DIST_FUNCTION_VERSION_DEFAULT to create an ARParam with the current lens distortion model, or a lesser integer to use an earlier version.

Returns: 0 if the function completed successfully, or -1 in case of error.

◆ arParamClearWithFOVy()

int arParamClearWithFOVy	(	ARParam *	param,
		int	xsize,
		int	ysize,
		ARdouble	FOVy
	)

Create a camera parameter structure representing an idealised lens with specified field-of-view.
