Projective 2D - MDT26

Projective 2D

Also known as 8-parameter transformation. It is appropriate to use it when a 2-dimensional system non-parallel system. It is often used in photogrammetry. To perform the transformation at least four pairs of points are necessary.

Formulas:

where:

x\', y\' = Transformed X, Y coordinates

x,y = Original X,Y coordinates

a1...b3 = Transformation equation parameters
