What is 3D Machine Vision Technology?

Let’s begin with the basics: what exactly is a vision system?

A machine vision system is a set of parts that work together to use information from digital images to help with better and faster manufacturing and production.

Now, let’s dive deeper into it.

What is a 3D Vision System?

A 3D vision system is a kind of technology that uses cameras and special software to take and understand 3D pictures of things or places. It helps robots and automated systems “see” and understand their surroundings in three dimensions. This makes them better at moving around and working with the world. 3D vision systems are used in robot navigation, recognizing objects, doing assembly jobs, and more.

Difference Between 3D Vision & 2D Vision:

As we mentioned earlier, a 3D vision system can take and understand 3D pictures of things, while a 2D vision system can only do 2D pictures. Here’s the deal: a 3D vision system gives more info about the shape, size, and position of objects it sees, making it easier for a robot or machine to move around and interact with the world.

On the other hand, a 2D vision system only tells you about the brightness and contrast of things it sees. This might not be as helpful for tasks that need to understand the space around them. It depends on the job you’re doing.

How Does a 3D Vision System Work?

3D vision systems often have one or more cameras on a robot or another machine. These cameras take pictures of what’s around, and special software turns these pictures into a 3D view. The software helps spot and follow objects, find shapes and patterns, and figure out where things are and how they’re positioned.


3D vision systems have many uses in different jobs, like robot navigation, recognizing objects, checking things, and putting stuff together. Here are some common examples:

1. Robot Navigation:

These systems help robots “see” in 3D, so they can move around tricky places and avoid obstacles. It’s handy in tasks like warehouse work, where robots need to dodge things and find their way.

2. Object Recognition & Tracking:

3D vision helps robots spot and follow objects, which makes them better at interacting with things. It’s useful in jobs like sorting and packing, where robots need to identify and pick up items.

3. Inspection & Quality Control:

These systems are great at checking things for problems. For instance, they can measure the size of something we make or find mistakes in a finished product.

4. Assembly Tasks:

3D vision helps guide robots and other machines as they put things together. For example, it can help line up parts and make sure they’re in the right place.

3D vision systems are flexible and strong tools that boost the performance and reliability of robots and other machines. They find use in various industries, like manufacturing, shipping, and healthcare.

Pickit 3D Assembly


3D vision systems find use in many industries, like manufacturing, logistics, healthcare, and more. Here are some examples:

1. Manufacturing:

They’re often used in manufacturing to check product dimensions and help with assembly. For instance, they can make sure a manufactured part is the right size and in the correct spot during assembly.

2. Logistics:

In logistics, 3D vision systems help robots and automated systems move around warehouses and handle objects better. This makes tasks like picking and placing stuff more efficient.

3. Healthcare:

In healthcare, these systems assist with medical procedures, like surgery and imaging. They can guide robotic surgical tools or create 3D body images for diagnoses.

4. Retail:

In retail, 3D vision systems aid in tasks such as sorting and packing products. They help robots identify and follow objects, so they can pick and place them more accurately.

In general, 3D vision systems are valuable in many industries, and they significantly boost the performance and reliability of robots and other automated systems.

How to Choose the Right 3D Vision System?

When you’re picking a 3D vision system, you need to think about a few things. The accuracy and resolution of the cameras matter, so does the software, and if it suits what you want to do. Here’s how to choose the right one:

1. Know What You Need:

First, figure out exactly what you need from the 3D vision system. This will help you understand what features and abilities it should have and compare your options better.

2. Camera Quality:

The accuracy and resolution of the cameras are super important. They affect how good the images are and how well the system works. Usually, higher accuracy and resolution mean more detailed 3D images, but they can also be pricier.

3. Software & Algorithms:

The software and algorithms used to handle the camera images are also a big deal. Look for systems that use advanced techniques like deep learning to get more information from the images and make the system work better.

4. Suitability for Your Needs

Think about whether the 3D vision system works for your specific task. If it’ll be in a tough environment, make sure it’s sturdy. If it needs to work super fast, look for one with a quick frame rate and low delay.

To sum it up, choosing the right 3D vision system means checking out your options and seeing if they match what you need. By following these steps, you can get a system that does the job well and is worth the investment.

Key Advantage:

3D vision systems have a big advantage over 2D ones. They show a more detailed and accurate view of the world. This helps robots and machines work better with their surroundings and improves tasks like recognizing and handling objects.

3D systems can also handle various lighting and environmental conditions, making them flexible and tough.


To sum up, 3D vision systems are a valuable technology for robots and automated systems to understand their surroundings in 3D. They find use in various tasks like robot navigation, recognizing objects, checking things, and putting stuff together.

Compared to 2D vision systems, 3D systems offer a more detailed and accurate view and can work in different lighting and environments. Overall, 3D vision systems are flexible and strong tools that boost the performance and reliability of robots and automated systems.
