Benefits of Vision Measurement Systems

Vision measuring systems use a computer and camera to inspect or measure objects that are difficult for humans to see. They are a great solution for many industries that require quality inspections at high speeds.

A vision system for inspection and measurement can work much faster than a traditional optical comparator and is not as bulky or powerful. They also have a number of other benefits such as:

High Accuracy

Vision inspection systems use a video camera to examine an object and detect the presence of a feature such as a line, arc or circle in 2D or a cone, sphere or cylinder in 3D. They then use computer software to reconstruct the image into a measured value.

This information can be used to automatically correct the system, which eliminates human error and increases productivity. This process also helps to reduce the amount of time spent fixing mechanical components, which saves manufacturers money on labor costs and repair fees.

Because of their high resolution, vision measurement systems can detect physical details on parts that may be too small for a human to see. This can help companies meet strict industry tolerances and avoid costly mistakes, especially when manufacturing expensive parts. In addition, it can help improve quality by reducing scrap and ensuring consistent results. It can also increase production speed and help companies meet demanding delivery deadlines.

Reduced Errors

A vision inspection system can be embedded on a conveyor line and can recognize unique product shapes, measure parts quickly and efficiently, and verify that part locations are correct. These systems also help eliminate costly human errors due to operator fatigue or person-to-person variances.

These systems can spot flaws on products that aren’t up to standards before they reach customers, reducing scrap and material waste. For high-priced components, this can save thousands of dollars.

The ability of these systems to detect and respond to errors reduces production downtime, allowing you to meet deadlines faster. They can also minimize the damage caused by mechanical parts touching each other, reducing maintenance fees and repairs.

Reduced Downtime

Vision inspection systems are able to detect defects and issues in real-time, such as color anomalies, blemished prints, missing letters or incorrect part numbers. This can significantly reduce the need for human involvement and save time. It also helps eliminate error and allows for greater production speed. This can help to cut down on costs, including healthcare benefits, 401k contributions and labor rates.

Using a video camera with a zoom or telecentric lens, these systems are able to identify edges on the part and use software to calculate dimensions based on those images. This allows them to measure 2D features and in some cases 3D ones as well.

Unlike CMMs, these machines do not require precise positioning or calibration. They can quickly and easily inspect hundreds or thousands of parts per minute, as well as examine object details too small to be discerned by the human eye. These capabilities can be especially helpful when assessing complex or difficult-to-maneuver products and components.

Increased Throughput

In a similar manner to CMMs, vision measurement systems can take detailed three-dimensional measurements – however, they are much quicker and easier to use than portable measuring arms. They can also be fitted with a touch probe system to measure in 3D, and they offer CAD/DXF compatibility (which optical comparators do not).

Machine vision systems can help automate production lines, speed up processes and scale up manufacturing. Moreover, they allow you to perform 100% inspection of products and parts for quality control, helping you meet and exceed customer expectations.

In addition, a vision inspection system helps you to maintain clear records of manufacturing processes, which can assist with regulatory compliance in industries like pharmaceuticals and food. In addition, the ability of a vision system to read bar codes and symbology makes it easy to track work-in-process (WIP) rates to facilitate Just-In-Time manufacturing, thus reducing inventory costs and preventing stockouts. Furthermore, a vision system can easily identify printing anomalies such as incorrect color shades and blemished prints, thus helping you to avoid costly production mistakes.
