Clear definitions for a clear VISION

1
EMVA 1288 Standard for Measurement and
Presentation of Specifications for Machine Vision
Sensors and Cameras

• Clear definitions for a clear VISION

Workshop Program

• Why we need 1288
• Prof. Bernd Jähne, University Heidelberg
• Organization of 1288 Working group and standard
• Martin Wäny, AWAIBA
• Basic Information
• Dr. Emil Ott PCO
• Module 1 Sensitivity, temporal and spatial
  noise, Dynamic range
• Dr. Fritz Dirks BASLER
• Module 2 Linearity and linearity error
• Dr. Kari Siren TVI

Motivation

• Existing Standards for cameras are not suitable
  for MV
• Each Sensor and Camera Manufacturer has its own
  definitions
• The Customer is left guessing with datasheets

Approach

• Modular standard framework
• New modules are to complete the standard rather
  than to replace previous versions

The modular approach protects investment in
measurement equipment, processes and education
7
Each Module contains
Mathematical Model
Measurement setup
Fit the data to the model
Data Presentation
Clear understanding
Happy Customer

Current Status Roadmap

• First Module Released in Sep 2005 (Sensitivity,
  SNR)
• Second module (linearity) in Preliminary release.
  Official release planned in Q1 2007
• Vision 2006 shows many 1288 compliantly
  characterized products
• Preliminary release of third and fourth module
  (Color Defects/Artifacts) planned for Q1 2007
