Comparing and Analyzing of Orthogonal Geometry Ellipse Fitting,Algebra Fitting and Ellipse Fitting

摘要

Passing comparing orthogonal geometry ellipse fitting method with algebra method and ellipse definition method,in consideration of the defect of original method,full applied advantage of orthogonal concept and least square (LS) principle,we carried orthogonal geometry fitting method on ellipse.The experiment expressed that orthogonal geometry fitting method make up other method nicely and obtained good result.
