public class TLcdPolynomialRasterReferencer extends java.lang.Object implements ILcdRasterReferencer
If the initial reference of the model tie points is also an
ILcdGridReference, then the newly created grid reference will
have exactly the same parameters, except that the initial projection is
wrapped inside the rectified projection. Thus, you can consider the new
reference system as being equivalent to the original reference, but slightly
adjusted to match the tie points.
If the initial reference of the model tie points is an
ILcdGeoReference, then the newly created grid reference will
ILcdGridReference with the same geodetic datum.
|Constructor and Description|
Creates a new TLcdPolynomialRasterReferencer that creates polynomial approximations of the given degree.
|Modifier and Type||Method and Description|
Creates a raster reference for an image of a given size, based on pairs of tie points.
public TLcdPolynomialRasterReferencer(int aPolynomialDegree)
public ILcdRasterReference createRasterReference(int aImageWidth, int aImageHeight, ILcdPoint aImageTiePoints, ILcdModelReference aModelReference, ILcdPoint aModelTiePoints, ILcdPoint aMappedModelTiePointsSFCT)
An optional array can be provided for obtaining the model tie points transformed to image coordinates on return. These reflect the effects of the referencing. The differences between the transformed model tie points (expressed in pixels) and the original image tie points (also expressed in pixels) provide a measure for the success of the referencing. With a perfect raster reference, the resulting model tie points correspond to the original image tie points.
aImageWidth- the image width of the raster, expressed in pixels.
aImageHeight- the image height of the raster, expressed in pixels.
aImageTiePoints- the image tie points, expressed in pixels.
aModelReference- the reference of the model tie points.
aModelTiePoints- the model tie points corresponding to the image tie points, expressed in model coordinates.
aMappedModelTiePointsSFCT- an optional array for obtaining the the model tie points mapped to image coordinates upon return. This parameter may be
null, if the mapped points are not required.
