Constructor & Destructor Documentation

HuginBase::PTools::Transform::Transform ( )

inline

construct a new Transform object, without initializing a transformation

use createTransform or createInvTransform to create a transformation, and transform to execute it.

Member Function Documentation

void HuginBase::PTools::Transform::createInvTransform	(	const vigra::Diff2D &	srcSize,
		VariableMap	srcVars,
		Lens::LensProjectionFormat	srcProj,
		const vigra::Diff2D &	destSize,
		PanoramaOptions::ProjectionFormat	destProj,
		const std::vector< double > &	destProjParam,
		double	destHFOV,
		const vigra::Diff2D &	origSrcSize
	)

create image->pano transformation

Parameters

srcSize	size of input image
variables	of input image
srcProj	projection of the image
destSize	output panorama size
destProj	panorama projection
destHFOV	HFOV of panorama
origSrcSize	original input image size, 0,0 if the same as srcSize.

origSrcSize is needed, because the variables are only valid for the original input size. To transform a smaller image, like a preview image, the parameters have to be adjusted. The origial image size, for which variables are valid needs to be know for this.

initialize pano->image transformation

Todo:

The next few functions could be rewritten to make more effective use of SrcPanoImages.

Steps of transform:

1. pano_proj -> erect
2. rotate equirect?? ( rotate yaw in screenpoints ? )
3. spherical -> erect ??
4. persp_sphere ( rotate point with rotation matrix)
5. sphere_tp -> image_proj
6. distortion correction
7. shift image origin
8. shear image
