An efficient and robust stripe extraction method for structured light measurement system

Stripe extraction methods are a fundamental step for the structured light three-dimensional measurement systems. This work proposes an efficient and robust stripe extraction method for structured light measurement system. In this paper, a novel method for extracting the stripes from structured laser lights is presented which is based on the Steger stripe extraction algorithm used to identify the structure of light stripe and smoothing spline fitting algorithm for interpolation to obtain single continuous stripe and the coordinates of the clustered stripes are calculated to form a phase map through a cubic polynomial interpolation procedure. The experimental results show that the work is particularly efficient and robust
