Проведен сравнительный анализ эффективности методов поиска стыка деталей при автоматической сварке двух типов: труба - пластина и пластина - пластина. Предложено четыре метода: корреляционный метод; использование нейросетей; аппроксимация прямыми; аппроксимация прямыми и окружностями после сегментации. Отмечаются достоинства и недостатки каждого метода, условия их адекватной работы.
This paper considers mathematical methods for finding welding point for two type of joint: pipe - plate and plate - plate. Four algorithms are offered: the correlation method - the fastest way, allows to allocate edges of details, but it is sensitive to rotations of the parts; the use of neural networks - with the right training, allows you to select the joint parts, comparable in speed to the correlation method; approximation by straight lines - fast method, allowing to find a joint of details in the presence of emissions and other insignificant distortions; approximation by straight lines and circles - the slowest algorithm, but it is insensitive to large and small distortions and emissions. The algorithms have their advantages and disadvantages, it is said that for each task, you must use the optimal method.
