Research Of Taken-Shape Steel Photoelectricity On-Line Examination And Control System

In the modern industry development the Taken-shape steel is one of essential important products, widely applies to the construction, the spare-part processing and any various professions, and it holds the quite important status in the national economy. However the present steel products production enterprise generally uses artificially count method. This method's labor-intensity is big, working efficiency is low, the serial production ability is limited, also the accuracy guaranteed with difficulty. In view of this kind of situation, the development can carry on the examination system to the steel products which automatically counts, may effectively enhance the labor productivity, in the change tradition depends on the worker "does eye arithmetic does mental arithmetic" the processing pattern, liberates the worker from arduous physical labor and in the adverse circumstance, causes the steel products production line to count the link realization mechanization and the automated operation.This article realizes through the recognition of Taken-shape steel side picture to catch on Taken-shape steel's photo electricity on-line examination. First, in view of the picture illumination non-uniformity characteristic, to the scene real-time gathering Taken-shape steel's side picture carries on the format conversion, the image enhancement, uses the auto-adapted two-value reduction to carry on the picture pretreatment to the primitive picture. Next, in view of the picture adhesion Partial division question, after has studied the common division algorithm, Proposed in transforms by the distance switching two-value-charts after is away from the distance-gradation chart, completes the division with the watershed transformation.Finally, in counts to the Taken-shape steel recognition, the article in the picture distance switching method foundation, in view of the section side surface mostly for the circle, also the section for the steel, its side-surface area cannot have the change; According to the system's request-speed's response quick characteristic, this article proposed one kind of new recognition algorithm - DM algorithm. The effect is more-effective than the existing method.
