boofcv.struct.distort.PixelTransform2_F32

boofcv.alg.distort.spherical.EquirectangularDistortBase_F32

All Implemented Interfaces:

boofcv.struct.distort.PixelTransform

Direct Known Subclasses:

CylinderToEquirectangular_F32, EquirectangularRotate_F32, PinholeToEquirectangular_F32

public abstract class EquirectangularDistortBase_F32
extends boofcv.struct.distort.PixelTransform2_F32

Base class for all distortions from an equirectangular image. The output image precomputes pointing vectors from a canonical view. The source pixel is then computed by rotating each vector and computing the longitude and latitude.
