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.

Constructor & Destructor Documentation

◆ SphericalWarper()

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

Construct an instance of the spherical warper class.

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