What are the four basic types of machine vision systems?


Machine vision systems play a crucial role in various industries. These systems help in enabling automated inspection, quality control, and object recognition. These vision-measuring machine systems utilize advanced technologies to capture, process, and analyze visual information, imitating human vision capabilities.

In this blog post, we will describe four basic types of machine vision systems to develop a better understanding:

Types of machine vision systems

Let’s have a look at the four main types of machine vision systems. So, here we go:

1. 1D machine vision system

The 1D vision measuring machine system is designed to inspect objects and surfaces along a single line or axis. It utilizes a linear camera to capture images and analyze them for defects, measurements, or barcode scanning.

This type of system is used for different tasks. These tasks usually include reading barcodes on packaging, verifying product labels, or measuring the length of objects.

1D machine vision systems can measure the length, width, or height of objects on a conveyor belt. As a result, the application of a 1D machine vision system is in quality control and sorting based on size.

The 1D machine vision system offers high accuracy and speed in applications that require linear inspection. The fact is truer due to its ability to analyze data within a narrow field of view. Above all, 1D machine vision systems eliminate human errors, reduce operator fatigue, and improve overall efficiency. These machine vision systems do so by automating tasks such as barcode scanning and measurement.  

2. 2D area array scan system

The 2D area array scan system captures images in a two-dimensional plane. It provides a more comprehensive view of the object under inspection.

It utilizes an image sensor composed of an array of pixels, allowing it to capture multiple features and details simultaneously. This type of machine vision system is widely used in applications such as quality control, pattern recognition, and defect detection.

With its ability to analyze images in real time, the 2D area array scan system provides a versatile solution for industries ranging from automotive and electronics to pharmaceuticals. Additionally, 2D vision systems can read and interpret text, making them useful for applications such as document processing and verification.

Above all, the use of 2D vision systems reduces the number of defects, increases production yield, and minimizes downtime. It does so by enabling real-time inspection and analysis.

3. 2D line scan system

The 2D line scan system differs from the 2D area array scan system in terms of its scanning method. Instead of capturing an entire image at once, it scans objects line by line using a linear sensor.

This type of machine vision system is particularly useful for inspecting objects in continuous motion. These objects usually include conveyor belts or web-based materials.

The 2D line scan system enables the detection of defects, measurements, or irregularities in high-speed production lines. It is usually done by capturing images rapidly and sequentially.

Its applications include print inspection, surface inspection, and sorting tasks.

4. 3D machine vision system

3D vision systems add depth perception to the inspection process. It helps in enabling the analysis of three-dimensional objects. These systems utilize specialized technologies. These specialized technologies usually include laser scanning, structured light, or stereo vision. All of these help in capturing depth information and creating a 3D representation of the object.

3D vision systems are widely employed in different applications. These are specifically used in applications that require accurate measurements, volumetric analysis, or object recognition in complex environments.

Industries such as robotics, manufacturing, and logistics benefit from the capabilities of 3D vision systems. 3D machine vision systems help in different tasks, such as bin picking, robotic guidance, or dimensional inspection.
