Abstract

A simple structure, high stability, and high speed characterize laser triangulation. Aerospace, civil engineering, and many other applications use laser triangulation inspection methods. In various applications, laser triangulation is affected by a variety of factors. The paper proposes an improved circle fitting method for solving the problem of low accuracy of speckle center detection in laser triangulation systems. There is usually some deviation in the measurement results of circle centers when there are outliers in algebraic or geometric circle fitting methods. The center of the fitted circle is determined by combining edge detection and least squares circle fitting. Laser triangulation is, therefore, more accurate by improving the accuracy of the spot origin.
