Laguerre formula
text:
The Laguerre formula provides the acute angle ϕ between two proper real lines, as follows: where: Log is the principal value of the complex logarithm Cr is the cross-ratio of four collinear points P 1 and P 2 are the points at infinity of the lines I 1 and I 2 are the intersections of the absolute conic, having equations x 0 = x 1 2 + x 2 2 + x 3 2 = 0 , with the line joining P 1 and P 2 . The expression between vertical bars is a real number. Laguerre formula can be useful in computer vision, s
