Abstract

In this paper we propose an algorithm for autocollimators with cylindrical surfaced reflectors. We discuss it’s flow and how it can be achieved. Optimal flow can contain the following steps in the order, they should be performed: noise filtering, line width reduction, line separation, clustering, determination of an angle for each line.
