The use of OpenCV Library Tools to Isolate a Laser Line on the Surface of a Physical Model of a Heated Industrial Product
This article discusses the problems of controlling the geometric parameters of heated products in industry using computer vision systems. It is concluded that it is necessary to use physical modeling to ensure convenient and safe testing of computer vision algorithms in laboratory conditions with further transfer of the results to industrial production. The description of the stand and the physical model of the heated product is given, which allow such modeling and corresponding studies to be carried out. Attention is focused on its structural features and the equipment used. The principle of operation of the model is described, based on the fact that the wavelength emitted by heated metal products varies depending on the heating temperature. The use of image processing methods of a physical model based on the OpenCV library is investigated. The functions of highlighting a local area in the image of a physical model and functions that implement methods of preprocessing the resulting area the use of filters and contrast correction - are considered. Median and Gaussian filters are used. The functions of laser beam selection on the processed image are tested. As such functions, the functions implementing the methods of threshold and adaptive threshold image processing, the methods of Ocu, the edge detector Canny are considered.
