Range of application and classification of industrial image processing

Classification of inspection tasks in industrial image processing

Object identification


Acquisition of

  • Shape and geometry
  • Dimension
  • Structure/topology, color, texture

Completeness check


  • Yes/no statement (instead of classification)
  • Check for presence of all individual parts before automatic assembly or after production step
  • Condition detection: does the object have certain characteristics? 

Position detection


  • Position and orientation of an object point
  • Two-dimensional or three-dimensional space
  • Use of feature calculations or template matching methods 

Form and dimension


  • Metrological acquisition of geometric values
  • Early detection of faulty parts
  • Good parts must comply with tolerances
  • Application e.g. in toolmaking and stamping systems

Surface inspection


  • Waviness, roughness
  • Local anomalies, color, texture
  • Surface defects
  • Contamination 

Inspection of the component interior


  • Microwave and terahertz radiation
  • Polarization imaging
  • X-rays
  • Ultrasound
  • Heat flow thermography
  • Eddy current
  • etc.
