WebJun 1, 2011 · Our task is to compute the coefficients so that the circle of (1) or the ellipse of (2) fits the given points , as closely as possible. The least squares (LS) estimator minimizes the algebraic distance (3) for circles and (4) for ellipses. This approach is also known as the direct linear transformation ( DLT ) ( Hartley and Zisserman, 2004 ).
