JIIA Announces World’s First Standard of Lighting for Machine Vision and Image Processing Systems
POSTED 08/31/2011
TOK
The standard (JIIA LI-001-2010 Lighting for Machine Vision/Image Processing System - Fundamentals of Design and Specifications on Brightness of Optical Irradiation) was unanimously approved in June 2011.
JIIA had proposed the standardization of lighting specifications for machine vision and image processing, followed by four and a half years of deliberations of its Lighting Working Group (20 member corporations today) since the founding of the Group. Voting results by JIIA member corporations and international liaison members after one-month voting period were announced prior to the approval, showing a total of 16 votes in favor, no oppositions and no abstentions.
This standard was drafted based on the cooperation agreement on standardization by JIIA, AIA, and EMVA. Global adoption follows a three-month international appeals period.
This standard defines the basics of lighting specifications for machine vision and image processing systems and makes it possible to determine the brightness and light-dark profiles of images based on the specifications of lighting products. Image contrast depends on the physical properties of the light source, lighting and observation methods, spectral characteristics of the imaged object, properties of the imaging optics, spectral characteristics of the optical sensor and camera’s gain and response properties. This standard makes it possible to clearly determine the brightness of lighting systems as viewed by the camera, by means of defining the lighting methods starting from classifying types of light returned from the object, where ambiguities existed previously, to the methods of observation.
This standard also encompasses the fundamentals of lighting system design, and through clarification of designs, it shows a strong case for the high added value of optimization processes of lighting system design which have historically depended on experience and intuition. This standard clearly explains importance of the optimization processes of lighting system design, separately from lighting devices themselves, and thereby aims to improve the significant bottleneck for the expansion of machine vision systems, i.e., operational value of the role of system integrators.
The first edition of this standard will soon be available for download from JIIA website (http://www.jiia.org).
JIIA is planning to hold a workshop to explain the standard at VISION 2011 in Stuttgart, 8-10 November 2011.
Please contact JIIA to register for this workshop at info@jiia.org. Details on the date, time and location of the meeting will be sent to you.
