The VDI/VDE Society Measurement and Automatic Control of the Association of German Engineers (VDI) and the sector group Machine Vision of the VDMA (German Engineering Federation) have agreed to jointly disseminate a guideline of specifications for machine vision. The guideline for the preparation of a requirement specification and a system specification is available as VDI/VDE/VDMA 2632 Part 2.
According to the VDI and VDMA, machine vision systems have become an important tool of industrial production and they work fast and contact-free within the production system, executing their tasks in line with the production cycle. But the optical approach is technologically challenging, resulting in specific requirements for the operating environment as well as for the components to be inspected by the machine vision system.
A well-structured procedure is needed for implementing a machine vision application.
The standard VDI/VDE/VDMA 2632 Part 2 is a guideline specifically geared to these systems and helps to prepare requirement and system specifications covering all issues relevant for later project management. The aspects listed can be applied to measuring as well as positioning, inspection and sorting tasks.
By cooperating with VDI, VDMA Machine Vision is distributing VDI/VDE/VDMA 2632 Part 2 not only to the machine vision community, but also to users of machine vision systems, since the standard helps to avoid misunderstandings and supports both suppliers and customers of machine vision systems in handling projects efficiently and successfully.
VDMA has produced a video clip illustrating the benefit of carefully prepared requirement and system specifications for machine vision projects in compliance with VDI/VDE/VDMA 2632 Part 2.
The cooperation between VDI and VDMA will go beyond this standard: "We are currently working on yet another standard concerning the acceptance test of classifying machine vision systems," says Michael Heizmann, chairman of the expert committee on machine vision at the VDI/VDE Society Measurement and Automatic Control. "We are pleased that the VDMA is motivating its members to become active in this body because we want to prepare concepts for this important issue that are not only scientifically sound but are also practice-oriented."
The standard VDI/VDE/VDMA 2632 Part 2 "Machine Vision - Guideline for the preparation of a requirement specification and a system specification" is published by the VDI/VDE Society Measurement and Automatic Control.
