Visual inspection software PM-KB™

developmentimage analysisdata analysis

PM-KB is a dedicated, turnkey system for automated visual inspection of illuminated keyboards. Illuminated keyboards and keypads can exhibit variations in brightness and color from key to key, and even within keys, that are noticeable to the end-user. This inconsistency can detract from the user experience and, in extreme cases, these variations may strongly impact product usability. A member of the Radiant Vision Systems ProMetric Software family, the PM-KB system combines application-specific software and a ProMetric® Imaging Colorimeter or Photometer to perform rapid, automated visual inspection of backlit keyboards and keypads for character luminance and chromaticity, and assess overall keyboard luminance and color uniformity. PM-KB also tests to ensure that key caps are installed correctly and that each key is in its proper location. PM-KB is a dedicated testing system and is easy to set-up and operate. PM-KB uses a ProMetric imager to test all keys and characters simultaneously, capturing and processing data much faster and more consistently than a human inspector or a spot measurement device. Multiple Testing Options PM-KB allows users to define a complete set of measurement conditions and pass/fail criteria for specific points of interest on any keyboard or keypad, including: the total number of allowed individual character failures; the minimum luminance uniformity between characters; the maximum color difference between characters (when color is measured). Different keyboard models are stored individually for reference. To simplify switching between multiple models, you can automatically apply a reference model based on the model being tested,
