Description
polar_trans_contour_xld_invpolar_trans_contour_xld_invPolarTransContourXldInvPolarTransContourXldInvpolar_trans_contour_xld_inv transforms the polar coordinate
representation of a contour, stored in PolarContourPolarContourPolarContourpolarContourpolar_contour, back
onto an annular arc in Cartesian coordinates, described by the radii
RadiusStartRadiusStartRadiusStartradiusStartradius_start and RadiusEndRadiusEndRadiusEndradiusEndradius_end and the angles
AngleStartAngleStartAngleStartangleStartangle_start and AngleEndAngleEndAngleEndangleEndangle_end with the center point
located at (RowRowRowrowrow, ColumnColumnColumncolumncolumn). All of these values can
be chosen as real numbers. In addition, the dimensions of the
virtual image containing the contour PolarContourPolarContourPolarContourpolarContourpolar_contour must be
given in WidthInWidthInWidthInwidthInwidth_in and
HeightInHeightInHeightInheightInheight_in. WidthInWidthInWidthInwidthInwidth_in-1 is the column coordinate
corresponding to AngleEndAngleEndAngleEndangleEndangle_end and HeightInHeightInHeightInheightInheight_in-1 is the
row coordinate corresponding to
RadiusEndRadiusEndRadiusEndradiusEndradius_end. AngleStartAngleStartAngleStartangleStartangle_start and RadiusStartRadiusStartRadiusStartradiusStartradius_start
correspond to column and row coordinate 0. Furthermore, the
dimensions WidthWidthWidthwidthwidth and HeightHeightHeightheightheight of the virtual output
image containing the transformed contour XYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour are
required. The output contour is cropped at the borders of this
virtual output image.
polar_trans_contour_xld_invpolar_trans_contour_xld_invPolarTransContourXldInvPolarTransContourXldInvpolar_trans_contour_xld_inv is the inverse function of
polar_trans_contour_xldpolar_trans_contour_xldPolarTransContourXldPolarTransContourXldpolar_trans_contour_xld.

returns the contour
ContourContourContourcontourcontour, restricted to the circle
around (
RowRowRowrowrow,
ColumnColumnColumncolumncolumn) with radius
RadiusRadiusRadiusradiusradius,
as its output contour
XYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour.
Note that XYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour can consist of more than one
contour because PolarContourPolarContourPolarContourpolarContourpolar_contour may be cropped at the borders
of the virtual output image given by WidthWidthWidthwidthwidth and
HeightHeightHeightheightheight.
If more than one contour is passed in PolarContourPolarContourPolarContourpolarContourpolar_contour, their
transformations are computed individually and stored as a tuple in
XYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour. However, since one contour may be
transformed into several contours, there is no relation between the
indices of the contours in the input tuple PolarContourPolarContourPolarContourpolarContourpolar_contour and
the indices in the output tuple XYTransContourXYTransContourXYTransContourXYTransContourxytrans_contour.
Further Information
For an explanation of the different 2D coordinate systems
used in HALCON, see the introduction of chapter
Transformations / 2D Transformations.
Attention
Only the contour points are transformed. As the polar transformation
is not affine, polar_trans_contour_xld_invpolar_trans_contour_xld_invPolarTransContourXldInvPolarTransContourXldInvpolar_trans_contour_xld_inv only produces
reliable results if the spacing of the contour points is
small. Existing attributes are not transformed.
Execution Information
- Multithreading type: reentrant (runs in parallel with non-exclusive operators).
- Multithreading scope: global (may be called from any thread).
- Automatically parallelized on tuple level.
