What is a Vision Inspection System?

The technology of vision inspection systems is utilized for performing high-speed and reliable quality control.

Machine Vision

This technology helps ensure the quality of the products and improve overall efficiency as manual labor is released from repetitive, as well as challenging, inspection tasks. Furthermore, through digitizing the inspection process and generating documenting data, vision inspection systems can be utilized to help generate production data and statistics.

Vision inspection systems help by facilitating production optimization. Because of their broad applications, as well as efficiency, vision inspection systems are already widely used in many industries including electronics, pharmaceuticals, food and beverage, automotive, labeling, printing, and packaging sectors. Many other industries, meanwhile, are just now beginning to realize their potential.

The Components of a Vision Inspection System

The components of a vision inspection system include the following:

  • They utilize sensors that serve to identify the incoming objects’ presence.
  • Cameras are the eyes of the system. These are used to acquire images of the objects that need to be inspected.
  • Their lights and housing ensure optimal light for the acquisition of the image.
  • A PLC is used to control the system logic i.e. inputs, outputs as well as other actions from the components of the hardware.
  • These systems then require an industrial computer that runs the vision inspection software required to analyze the images acquired and provide an HMI.
  • Finally, an operator panel is required which is responsible for visualizing data and enabling operators to control the system.

How Vision Inspection Works

  1. Image Acquisition

    When an incoming object draws closer to the system, a sensor detects it. Light sources, as well as cameras, act on the input of the sensor by lighting up the area. They also capture an exact image of the object in real time.

  2. Image Processing and Analysis

    Algorithms as well as several specific filters are applied to pre-process the acquired image. This is done for detecting the product in the image and highlighting the key features of interest. Algorithms are then used based on the filtered image for generating a data object. The algorithm design impacts the efficiency of image processing and analysis.

  3. Result Evaluation

    The system’s software will then compare the extracted data object with a set of predefined tolerances, which defines the target quality level of a producer.

  4. Decision

    Finally, based on the set tolerances and the comparison between the processing results, decisions are then made by the system. At that time, the object that has been inspected will be given classification, for example, passed or failed.

  5. Process Control

    Other vision inspection systems use the gathered inspection data for spotting trends in production, and provide recommendations to the machine operators for production optimization. This can be achieved through data platforms that give production data overviews highlighting crucial production information.

Types of Vision Inspection Systems

The different types of vision inspection systems include:

PC Based

These systems have an industrial computer that is responsible for managing and communicating with all the peripheral devices like cameras and lighting components. PC-based vision inspection systems provide high computing power as well as flexibility. They are recommended for complex applications where there is a requirement for carrying out multiple inspection tasks at a faster rate using high-performance hardware. However, their size and cost can be significant factors to be considered.

Line Scan Camera

Compact

This is a lighter version of a PC-based system. This type of vision inspection system may require some tradeoff between cost and performance but typically provides enough capability for less-demanding applications. This system consists of a graphics card that is responsible for acquiring and transferring the information elsewhere.

Smart Camera-Based

This is the simplest and cheapest solution of all vision inspection systems. This system is based on smart and intelligent cameras that are usually used in combination with standard optics as well as lighting. Although this system is typically recommended for simple applications, it has a very easy setup and it provides functionalities that are similar to those of classic vision systems in a very compact form factor.

Applications of Vision Inspection Systems

  • Food and packaging appearance inspection
  • Presence or absence check
  • Color inspection
  • Orientation check
  • Label check, as well as verification
  • Seal inspection, as well as validation
  • Foreign object detection

Benefits of Vision Inspection Systems

  • They provide automated quality control that allows the enjoyment of a reliable system that will deliver time and time again.
  • A vision inspection system helps to ensure that every product a business produces will meet the specifications of the customer.
  • These systems lead to higher quality as well as increased productivity.
  • Vision inspection systems also lower the costs of production.
