Definition of a project
Definition of a project In an application round objects with a diameter of 400μm should be counted. The objects vertically fall through a glass tube at a speed of approx. 2,5m/s and land in a product there.
An already existing system has counted the objects by means of photo sensors. Here inaccuracies occur the objects isolated jump back into the glass tube. The cause for that is disadvantageous striking in the product. In that case the existing photo sensor system counts the object several times.
Method of resolution of image processing
An image processing system with a line-scan camera should solve the problem. By the special adjustment of the camera the image processing system makes it possible to determine the fall direction of the objects only with one camera.
Besides the considerably increased measurement accuracy the image processing system offers further interesting advantages compared with a „blind“ system. The registered objects are already displayed visually during the process for the operating staff. By that the response time for failures is considerably shortened. Furthermore additional monitoring is possible. For example the size of the objects could be measured in order to recognize deviations in speed.
Possible upgrading variants
By that system also smaller and faster objects can be recognized. The communication with other control systems is possible via TCP/IP or digital IOs.
Flexible configuration based on experience
The team of Quality Automation GmbH resorts to great experience in the field of image processing. This enables a comprehensive advisory service and a flexible integration of the systems at the customer.
