Machine vision: Technology of industrial automation

Some company have the multidisciplinary knowledge and experience required for the development and implementation of machine vision systems. A significant added value of the services is an individual solution processing the output data of the system. Thanks to this, it is possible to offer a sophisticated solution connecting machine vision and computer systems. So the production process is even more efficient and reliable.

Advantages of machine vision

One significant advantage of the system is the ability to graphically display the results in the evaluated images and their subsequent display. This is clearer and more understandable for users than, for example, tabular data. Various graphic elements, such as color-coded marks or text, can be added to the processed images. Outputs in this form can be used by users for more operative responses and quick interventions in the production process.

In some cases, it is also desirable to create records of the obtained outputs for later use. This can be, for example, detailed product or process evaluation information that can be used to compile production volume and quality statistics for the purpose of planning or implementing process adjustments.

Customized solutions

The company DZOptics designs each machine vision system based on individual requirements and specific conditions of the given operation. As an integrator, he first performs a detailed analysis of customer requirements. Based on it, always chooses the optimal path in the form of system architecture design, selection of hardware components and software resources.

Operating conditions are addressed in terms of parameters such as temperature, humidity or vibration. And according to them, suitable components designed for the respective industrial plants are selected. Sometimes it is necessary to operate the system at higher temperatures, such as in a foundry. And use a camera with an extended operating temperature range, or provide it with a cooling cover. In operations using vibrating feeders for the transport of objects, systems without bearings and rotating components are selected, such as plate discs or fans or durable machine vision lenses with locking rings. Dusty environments require the use of passive cooling equipment or a camera with special covers that protect the machine vision lens from splashing liquid.

Connectivity and user outputs

In addition to the design of the scanning system and the provision of input image data for the acquisition and subsequent processing of the required information, the necessary connectivity is also addressed. The system can also be integrated with programmable logic controllers. The system can communicate using digital signals, use fieldbuses, or connect to enterprise information systems or manufacturing information systems.

The method and form of publishing user outputs, which are defined in cooperation with the customer, is also very important. These can be simple information messages, numerical measurement values, images with graphics or graphs. You can choose from several options to view the inspection results. Often, only a display connected to the system and located in operation may be fully sufficient. More complex outputs are then written to a file or database or made available to the user using a web application that presents the results on any device connected to the Internet using a web browser.
