Предшествующий уровень техники State of the art
Существует весовое оборудование для взвешивания связанного пакета прутков перед отправкой заказчику. До настоящего времени пачка прутков сдавалась заказчику по весу пачки. В последнее время заказчики стали требовать от поставщиков в сопроводительных документах кроме веса пачки указывать точное количество прутков. При этом определение количества прутков по геометрическим размерам прутков в пачке, плотности материала и общему весу пачки дает ошибку в несколько прутков в связи с погрешностью весового оборудования. There is weighing equipment for weighing the bundled bar package before shipping to the customer. Until now, a bundle of bars has been delivered to the customer by the weight of the bundle. Recently, customers have begun to require suppliers to indicate the exact number of bars in addition to the weight of the bundle in the accompanying documents. Moreover, the determination of the number of rods by the geometric dimensions of the rods in the bundle, the density of the material and the total weight of the bundle gives an error of several rods due to the error of the weighing equipment.
Поставщики прутков вынуждены выполнять пересчет прутков в пачке вручную, что удорожает и замедляет технологический процесс. Bar suppliers are forced to recalculate bars in a bundle manually, which makes the process more expensive and slows down.
Сущность изобретения SUMMARY OF THE INVENTION
Технический результат изобретения состоит в автоматическом подсчете прутков в сортопрокатном производстве перед отправкой прутков заказчику. Количество прутков определяется путем обработки сигналов с
видеокамер и/или устройств объемного сканирования. Обработку сигналов осуществляет специальное программное обеспечение. The technical result of the invention consists in the automatic calculation of the bars in the rolling mill before sending the bars to the customer. The number of bars is determined by processing signals with camcorders and / or surround scanning devices. Signal processing is carried out by special software.
Заявляется способ подсчета количества произведенных прутков в сортопрокатном производстве заключающийся в том, что рольганг, подающий прутки на взвешивание, оборудуется видеокамерами таким образом, чтобы обеспечить нахождение пространства подающего рольганга в зоне видимости камер. По данным от камер с помощью компьютерного анализа изображений строится 3D сцена, на которой каждый пруток является горбом на 3D поверхности; подсчет прутков производится в полностью автоматическом режиме путем подсчета количества горбов. A method for counting the number of produced rods in a section rolling production is claimed, which consists in the fact that the roller table feeding the bars for weighing is equipped with video cameras in such a way as to ensure that the space of the feeding roller table is in the camera visibility range. According to the data from the cameras, using a computer image analysis, a 3D scene is built on which each bar is a hump on a 3D surface; bar counting is carried out in a fully automatic mode by counting the number of humps.
В качестве камер используют TOF камеры и/ или устройство лазерного сканирования, сканирующее одну линию; при этом устройство расположено так, что линия сканирования пересекает все прутки на подающем рольганге. Краткое описание чертежей As cameras use TOF cameras and / or a laser scanning device that scans a single line; while the device is located so that the scan line crosses all the bars on the feed roller table. Brief Description of the Drawings
На Фиг.1 представлен результат сканирования лазерным сканером одной линии, пересекающей все прутки на рольганге. Figure 1 shows the result of scanning with a laser scanner one line crossing all the rods on the roller table.
Осуществление изобретения The implementation of the invention
Изобретение осуществляется следующим образом: рольганги, по которым прутки движутся на взвешивание, оборудуются видеокамерами. В том числе и TOF камерами [http://en.wikipedia.org/wiki/Time-of-flight_camera], способными получать сразу на выходе из камеры 3D изображения с высокой точностью. The invention is carried out as follows: roller tables, along which the rods move for weighing, are equipped with video cameras. Including TOF cameras [http://en.wikipedia.org/wiki/Time-of-flight_camera], capable of receiving 3D images with high accuracy immediately at the exit from the camera.
В запыленных помещениях и помещениях с плохой видимостью в качестве видеокамер можно использовать устройства лазерного сканирования, результатом работы которых также является формирование 3D изображений [http://www.metrologi.ru/information/item/2024-laserniy-3d- scanner].
При этом существуют устройства лазерного сканирования, которые сканируют только одну линию (2D сканер)In dusty rooms and rooms with poor visibility, you can use laser scanning devices as video cameras, the result of which is also the formation of 3D images [http://www.metrologi.ru/information/item/2024-laserniy-3d- scanner]. However, there are laser scanning devices that scan only one line (2D scanner)
[http://www.lase.de/en/sensors/lase-2000d-series.html]. При применении подобных устройств устройство должно быть расположено так, чтобы линия сканирования пересекала все прутки на рольганге. [http://www.lase.de/en/sensors/lase-2000d-series.html]. When using such devices, the device should be located so that the scan line intersects all the rods on the roller table.
На Фиг. 1 приведен результат сканирования лазерным сканером одной линии, пересекающей все прутки на рольганге. Каждый горб (всплеск) это отдельный пруток. Видно, что в данном конкретном случае через рольганг проходят 10 прутков. In FIG. 1 shows the result of scanning with a laser scanner one line crossing all the rods on the roller table. Each hump (splash) is a separate bar. It can be seen that in this particular case 10 rods pass through the roller conveyor.
В случае применения TOF камер или 3D лазерных сканеров результатом сканирования будет не линия, а поверхность, где каждый горб поверхности будет соответс твовать прутку. In the case of using TOF cameras or 3D laser scanners, the scan result will not be a line, but a surface, where each hump of the surface will correspond to a bar.
Подсчет горбов или всплесков является простой инженерной задачей. Counting humps or bursts is a simple engineering task.
Видеокамеры, результатом работы которых в отличие от лазерной или TOF технологии является «плоская» картинка, должны быть установлены таким образом, чтобы обеспечить нахождение пространства подающего рольганга в зоне видимости камер. По сигналам с камер для организации подсчета прутков необходимо построить 3D сцену. Video cameras, the result of which, unlike laser or TOF technology is a “flat” picture, must be installed in such a way as to ensure that the space of the feed roller table is in the camera visibility range. Using signals from cameras, to organize the calculation of bars, it is necessary to build a 3D scene.
Программное обеспечение для построения 3D сцен в настоящее время широко извес тно. 3D scene construction software is now widely known.
Например, PhotoModeler [http://www.osp.ru/data/www2/ap/1997/02/27.htm] решает задачу построения трехмерной модели на основании информации, полученной при помощи видеокамер с точностью близкой к лазерному сканированию. Программа создает исходные трехмерные модели путем преобразования двухмерной информации, содержащейся в изображениях с камер, в точно рассчитанные трехмерные точки, линии и плоскости.
После построения 3D сцены задача подсчета прутков снова сводится к задаче подсчета горбов или выбросов.For example, PhotoModeler [http://www.osp.ru/data/www2/ap/1997/02/27.htm] solves the problem of constructing a three-dimensional model based on information obtained using video cameras with accuracy close to laser scanning. The program creates initial three-dimensional models by converting two-dimensional information contained in images from cameras into precisely calculated three-dimensional points, lines and planes. After building a 3D scene, the task of calculating the bars again comes down to the task of calculating the humps or outliers.
