Research of the Technology of Flatness Dectction for Steel Strip Based on Linear Laser

This paper describes a laser-based line of strip flatness measurement system, described the composition and its working principle It presents a light stripes center extraction algorithm that based on gravity method. The algorithm first extracts the area of light strip by using gray-slope method, and...
