  1. 1. Enhanced image analysis, a tool for precision metrology in the micro and macro world

    Författare :Bita Daemi; Lars Mattsson; Peter Ekberg; Mikael Sjödahl; KTH; []
    Nyckelord :Image processing; image metrology; precision metrology; image correlation; subpixel; accuracy; uncertainty; Production Engineering; Industriell produktion;

    Sammanfattning : The need for high speed and cost efficient inspection in manufacturing lineshas led to a vast usage of camera-based vision systems. The performance ofthese systems is sufficient to determine shape and size, but hardly to an accuracylevel comparable with traditional metrology tools. LÄS MER
