Image processing guidelines updated

Image processing guidelines updated

Machine vision a key technology for measuring, inspection and positioning tasks in the production cycle. This is where the VDI/VDE/VDMA 2632 series of guidelines is intended to support users and solution providers in practice – Sheet 1 has now been published as a draft.

For users and suppliers, a common understanding of the requirements, framework conditions and performance to be provided by the image processing system is essential. Misunderstandings due to fuzzy terms and ambiguities increase the implementation effort or even jeopardize the success of the project. “Clear terms and an understandable explanation are the essential basis for project success,” says Dr.-Ing. Heiko Frohn, Managing Director Technology at Vitronic and member of the board of directors of VDMA Machine Vision division. “The new version of Sheet 1 of the VDI/VDE/VDMA 2632 series of guidelines prevents expensive misunderstandings.”

The aim of the revision was to make the technical terminologyclearer and easier to understand: Definitions of terms were clarified and ambiguities resolved. For example, the terminology surrounding the interaction of lighting, scene and camera system was revised and clearly visualized. The section on image evaluation is completely new. Until now, for example, the intuitive use of the terms reference pattern, boundary pattern, and ideal pattern carried a risk of misunderstanding.

Avoid misunderstandings, delays and costs

Developing a powerful classifier and configuring it in a target-oriented manner is a core competence of image processing. Capturing the performance of a classifier in practice and describing it through metrics is another. For all users who do not work with classification and misclassification rates, pseudo-error rates and assignment rates on a daily basis, the new edition of VDI/VDE/VDMA 2632 Sheet 1 is a valuable reference aid, as it summarizes the terms commonly used to evaluate a classification performance.

The comprehensive and preciseterminology collection of VDI/VDE/VDMA 2632 Sheet 1 helps to avoid misunderstandings and thus unnecessary delays and costs in the implementation of image processing systems. Since the draft guideline was already published in two languages (German/English), this also applies to projects with international partners.

The expert community is now called upon to carefully review the draft. Suggestions for improvement can be submitted by 31.12.2021 via the link below, so that the final guideline will once again become the recognized state of the art for the next few years.
