Detailed Description#

Warper that maps an image onto the unit sphere located at the origin.

Projects image onto unit sphere with origin at (0, 0, 0) and radius scale, measured in pixels. A 360 panorama would therefore have a resulting width of 2 * scale * PI pixels. Poles are located at (0, -1, 0) and (0, 1, 0) points.

Examples
samples/cpp/stitching_detailed.cpp.

Constructor & Destructor Documentation#

SphericalWarper()#

cv::detail::SphericalWarper::SphericalWarper(float scale)

Construct an instance of the spherical warper class.

Parameters

  • scale — Radius of the projected sphere, in pixels. An image spanning the whole sphere will have a width of 2 * scale * PI pixels.

Member Function Documentation#

buildMaps()#

Rect cv::detail::SphericalWarper::buildMaps(
Size src_size,
InputArray K,
InputArray R,
OutputArray xmap,
OutputArray ymap )

Builds the projection maps according to the given camera data.

Parameters

  • src_size — Source image size

  • K — Camera intrinsic parameters

  • R — Camera rotation matrix

  • xmap — Projection map for the x axis

  • ymap — Projection map for the y axis

Returns

Projected image minimum bounding box

warp()#

Point cv::detail::SphericalWarper::warp(
InputArray src,
InputArray K,
InputArray R,
int interp_mode,
int border_mode,
OutputArray dst )

Projects the image.

Parameters

  • src — Source image

  • K — Camera intrinsic parameters

  • R — Camera rotation matrix

  • interp_mode — Interpolation mode

  • border_mode — Border extrapolation mode

  • dst — Projected image

Returns
