The machine vision systems certification performed by VEA has as main purpose to validate the reliability of a vision system.
In fact, a camera system which is unknown the degree of reliability can produce considerable damage.

In 1998 we found in some of our customers need to find a method to objectively assess the reliability of a vision system. Over the years we have developed a system to evaluate and improve the characteristics of any system or vision sensor. With this certification and related calibrations, our customers have saved by reducing the damage, improved image and have gained new customers.

1) SCREENING: are analyzed a number of basis points common to all vision systems. Through a objective criterion is written a report card with votes on various aspects of reliability. The screening is a simple and economical mode to get a first assessment of the reliability of any system or vision sensor.

2) CLASSIFICATION: at this stage are drawn all vision system specifications, are also carried out a series of tests to assess the actual reliability. We highlight the criticality of the system and the system improvements. As a final step we create a calibration protocol.

3) CALIBRATION: having defined the calibration protocol, through periodic calibration ensures reliable performance of the vision system over time.

1) The use of vision systems for quality control, would certainly benefit, but the resulting reduction of human control gate to increase the extent of damage caused by a malfunction of the vision system. The regular CALIBRATION reduces the amount of damages due to malfunction and improves the functionality of vision systems.

2) Many vision systems are used without knowledge of their limitations and weaknesses, and the phrase "the vision system has gone mad" is one of the most used by users of these systems to describe a malfunction. The phase of SCREENING and CLASSIFICATION is useful to know the limits of vision systems and know the risk factor.

3) Any vision system which has minimum functionality can be certificated and calibrated.

4) The rating is calculated objectively. The factors derived from the results of a series of questions with unambiguous answer. The rating of the vision system is unique, universal, and not susciettibile to change due to interpretation.

5) For each calibration is prepared a document that certifies and quantifies the features of the vision system. This document is usually attached to the product to demonstrate to its customers the increases company's quality, bringing real benefits and image.

Courtesy of one of our customers, below shows a graph illustrating the liabilities derived from the systems of control with vision systems.
In 2005 begins the process of certification of their vision systems, and making some changes in the systems. At the end of that year our client had reduced such losses (in red and orange on the graph) repayable assistance facts (in blue). In 2006 losses were reduced to one fourth compared to the period before the interventions of calibration.

To date, this customer has not only reduced the direct losses will more than the cost of certification, but has acquired new orders because it has increased the quality of its products.
