Machine Vision 101: How it Works & What it’s Used in Robotics

Robotics is a rapidly growing field. In the last decade, the number of jobs in the field has grown by leaps and bounds, and it’s not just in manufacturing – hospitals, warehouses, and even homes are starting to use robots to help with tasks . In this blog post, we’ll explore the basics of machine vision and how it’s used in robotics.


What is Machine Vision?

Machine vision is a term that you might have heard before, but what exactly is it? In short, it is the ability of a machine to see and interpret the world around it , just like humans do. A variety of different fields, from manufacturing to security to driverless cars, use this technology.

How Machine Vision Works

A lot of people wonder how machine vision works . At its core, the system is just a way for computers to understand and interpret digital images. This process starts with an image sensor, which converts the light that hits it into digital data. An algorithm then processes this data and looks for certain features or patterns.
The algorithm then outputs a result, which can be anything from a simple label to a complex decision. So how do machine vision systems get so good at this? The answer is through a process called training. A machine vision system is trained by showing it millions of images, and telling it what the correct outputs should be. The system then uses this information to learn and improve its algorithms .

Applications of Machine Vision

Machine vision solutions applied in robotics have revolutionized industrial production and expanded the horizon on medical possibilities. Here are a few other explorations of these solutions.

Absence/Presence Detection

One of the benefits of machine vision is that it can be used for absence/presence detection. This means that it can detect when something is not in the right place, or when something is missing.
This can be useful in a variety of situations, such as when you’re trying to detect if a part is missing from an assembly line, or when you’re trying to find a particular item in a room full of clutter.

Automated Vision Testing and Measurement

This is a process where images of products or parts are captured and analyzed by a computer to test for defects or measure certain properties. This type of testing is faster and more accurate than traditional methods, and a variety of industries such as automotive, aerospace, and consumer electronics can use it.

Bar Code Reading

Machine vision is a technology that can read barcodes automatically. A variety of applications, from retail to manufacturing, use this technology. And it doesn’t just revolve around barcodes – it can also read all sorts of images and text.

Color Verification

What is color verification ? In short, it’s a process of using machine vision to ensure that products are the correct colors. This compares images of products to a known color standard. If the colors match, then the product is deemed to be correct. If not, then the product is rejected.
A variety of industries use color verification, from food and beverage to cosmetics and electronics. It’s a critical quality control step that helps to ensure that products are of high quality and meet customer expectations.

Defect Detection

In the manufacturing industry, quality control is essential. To ensure that products meet the necessary standards, manufacturers often use machine vision to inspect each item for defects . This process is generally very fast and accurate, and it can inspect a variety of different products, including electronics, automotive parts, and more.

The Use of Machine Vision in Robotics

Machine vision develops new capabilities for robots, such as the ability to identify and pick up objects. As this technology continues to evolve, we will likely see even more ways in which it can enhance the capabilities of robots. So far, machine vision has proven to be a valuable tool for developing safer, more efficient, and more versatile robots.
