Paper Abstract

In this paper, an effective method applied in laser spot center determination is described, which is based on multi-spectrum digital image processing. The laser collimation technique combined with digital image processing technique is adopted to realize the measurement of parallel cylindrical tubes with mono axis or multi-axes. The advantages of detection are non-invasive, high measuring accuracy; easily realizing the measuring procedure with automation and intelligence.
