Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Adaptive optoelectronic system for monitoring profilograms of shells of revolution A.N. SHILIN, D.G. SNITSARUK The article is devoted to the development of new methods for controlling the dimensions and shape of the cross-section of shells of revolution. The main problem of this problem is the determination of the center of the section, which is the base of the measurement. The article presents an analysis of existing methods, their structural and functional schemes, as well as their advantages and disadvantages. In the first method, the center is determined with the help of the described rectangle, and the profilogram of the inner surface of the part is recorded with the help of a range finder. This method does not provide the necessary accuracy of control for large dimensions of the part and cannot be used in the production of heated parts. In the second method, the center of the section is also determined from the center of the rectangle described; however, a projection transducer is used. This method has a complex control system, and the maximum accuracy is achieved only with details, the shape of which is an ideal ellipse or circle. Based on the analysis of existing methods, a method was proposed with which the center of the cross section is defined as the center of gravity of the projection of the entire cross section. The technical implementation of this method is given in the article. The device operates as follows: using a high-resolution camera, a crosssectional image is recorded in the end plane and its contour is more precisely identified using filtering algorithms. After that, with the help of the computer, the coordinates of the center are determined, and then the camera, with the help of actuators, moves to a position where the optical axis of the camera coincides with the center of the part. In this position, with a minimum error, the profilogram of the part is registered, which is necessary for controlling the process of shaping. The profilogram of the finished part can be used for optimal assembly of equipment.
