Abstract
As the detecting method of structured light, linear laser has been widely recognized in theory, but there still exist some problems when it comes to its application in industrial production. Based on the needs and features of steel bar and wire rod production, the present paper proposes the online detection of steel bar and wire rod’s cross-sectional shape and size by using linear laser as the structured light. Meanwhile, the present paper applies such a detecting method to the online detection of continuous casting billet’s size and the online automatic counting of steel bar and wire rod. Moreover, the validity and accuracy of the proposed detection are verified by experimental device and project cases.
