Abstract: This paper presents a new approach in calibrating a light sectioning measurement system. The developed method permits the calibration of such a system without previous knowledge of the exact positions of camera and laser. The basic concepts of this new approach and its advantages compared to common methods are discussed. Further, a possible implementation in an industrial process is given.
Direct least Square Fitting of Ellipses
, 1998
"... This work presents a new efficient method for fitting ellipses to scattered data. Previous algorithms either fitted general conics or were computationally expensive. By minimizing the algebraic distance subject to the constraint 4ac  b² = 1 the new method incorporates the ellipticity constraint ..."

Least Squares Fitting of Ellipses
, 2014
"... In this section, we will detail the least squares method used to t an ellipse to given points in the plane. In analytic geometry, the ellipse is de ned as a collection of points (x, y) satisfying the following implicit equation [1]: Ãx 2 + ˜ Bxy + ˜ Cy 2 + ˜ Dx + ˜ Ey = ˜ F, where ˜ F ̸ = 0 and ˜ B ..."

Least squares fitting of circles and lines
 Computer Vision and Pattern Recognition
, 2003
"... We study theoretical and computational aspects of the least squares fit (LSF) of circles and circular arcs. First we discuss the existence and uniqueness of LSF and various parametrization schemes. Then we evaluate several popular circle fitting algorithms and propose a new one that surpasses the ex ..."

Estimating Errors in LeastSquares Fitting
, 1995
"... While leastsquares fltting procedures are commonly used in data analysis and are extensively discussed in the literature devoted to this subject, the proper assessment of errors resulting from such flts has received relatively little attention. The present work considers statistical errors in the ..."

StateSpace Size Estimation By LeastSquares Fitting
"... We present a method for estimating the number of states in the continuous time Markov chains (CTMCs) underlying highlevel models using leastsquares fitting. Our work improves on existing techniques by producing a numerical estimate of the number of states rather than classifying the state space in ..."
