Machine Vision: vision systems in manufacturing

By 12.04.2023August 2nd, 2023Featured

Machine vision is a powerful technology that enables computers to process and interpret visual data. It has applications in various fields, including manufacturing, and can automate tasks, improve efficiency, and reduce costs, making it an essential tool for businesses and organizations.

What is machine vision?

Machine vision, also known as computer vision, refers to a field of artificial intelligence that focuses on enabling computers to interpret and analyze visual data. It involves the use of cameras or other sensors to capture images or video data, which is then processed by algorithms and software to extract useful information.

The technology is used to automate various tasks that would otherwise be done manually (many of which impossible to do with the human eye) making it more efficient and cost-effective.

How do vision systems work?

Machine vision involves several steps, including image acquisition, processing, analysis, and interpretation. 

In the first step, an image or video data is captured by a camera or other sensors. The data is then processed to remove any noise or unwanted information, such as shadows or reflections.
In the second step, the processed data is analyzed using algorithms and software to identify and extract features of interest. This can involve tasks such as object detection, recognition, and tracking. The algorithms and software can be trained using machine learning techniques to improve their accuracy and performance.
In the third step, the extracted information is interpreted to make decisions or take actions based on the analyzed data. This can involve tasks such as quality control, inspection, or monitoring. The output can be displayed on a screen or used to control other devices, such as robots or automated machinery.

The main components of a vision system are then:

  • Cameras
  • Image processing software
  • Computing platform

Real-world applications of machine vision

Machine vision has numerous applications in various fields, including manufacturing, healthcare, transportation, and security:

Healthcare: used to analyze medical images, such as X-rays and MRI scans, to aid in diagnosis and treatment. It can also be used for monitoring patients and tracking their movements and vital signs.

Transportation: used in transportation to enable autonomous vehicles, such as self-driving cars and drones. It can detect obstacles and navigate through complex environments, making transportation safer and more efficient.

Manufacturing: used to automate tasks such as quality control, inspection, and sorting. It can detect defects or anomalies in products, ensuring that only high-quality products are shipped to customers.

Security: used in security to monitor public spaces, such as airports and train stations. It can detect suspicious behavior or objects and alert security personnel to take action.

As the technology continues to evolve, we can expect to see even more applications and innovations in the field of machine vision. 

Are you looking to integrate a machine vision system?

Controlar provides industrial machine vision systems for inspection, automation and control.

We have developed machine vision solutions in a range of industries and in various applications, such as: clusters and displays testing (automated inspection of tell-tales, lightning calibration…), defect detection, process and quality control, and robotic offset assembly.

Main benefits include increased efficiency in regard to speed, accuracy, and reliability.

Controlar is currently undergoing a project with Visteon and Fraunhofer Portugal to develop an innovative machine for automotive display inspection, using machine vision and artificial intelligence.
