Definitions
- the present invention relates to a method for the automatic detection of objects and structures in materials, with a 1-chip color image camera which has N sensor pixels covered by primary color filters, onto which the material to be inspected is imaged.
- the present invention further relates to an arrangement for the automatic detection of objects and structures in materials, with a 1-chip color image camera which has N sensor pixels covered by primary color filters, onto which the material to be inspected can be imaged.
- Vüesstoffbahnen contaminations of different colors and defects within the scope of to recognize optical quality control usually learn the color distribution of the GUT material, ie the contamination-free or defect-free material, in a reference phase and save it in the form of a GUT classifier.
- each scanned image point of the material web is classified into the classes "GOOD” and "NON-GOOD” by a comparison with the GUT classifier obtained during the reference phase, and on the basis of this color class image the sorting, marking or Logging of the defect or contamination triggered (see, for example: Robert Massen, Pia Böttcher: "Shape and color: color image processing for industrial monitoring in real time", pp. 121 - 125, ed. Prof. Dr. Hartmut Ernst, in: machine vision, Electronics Journal Science and Practice, Europa-Fachpresse Verlag Kunststoff, ISBN 3-87207-004-5, 1990).
- a pixel of the class “object” or “structure” is generated if the signal value of the respective sensor pixel lies within the signal interval.
- K ⁇ N color image points are formed, at which K ⁇ N color signals are formed during an image, during a learning phase, a reference material is created for the N sensor image points of the color image camera a classification scheme with the classes “object” or “structure” and “background” is formed and based on the color signals of the K color image points.
- Fig. 1 shows the structure of a 1-chip color image sensor with RED, GREEN and
- large objects which are above the resolution limit are also detected electronically by at least three sensor image points for a color image point.
- -usarnmengeank and so K ⁇ N color image points are formed.
- a reference material is mapped onto the N sensor image points of the color image camera and a classification scheme with the classes “object” or “structure” and “background” is formed on the basis of the color signals of the K color image points.
- FIG. 3 An arrangement for carrying out the method according to the invention can be seen schematically in FIG. 3.
- Each of the N sensor pixels 12 of a color line camera arranged in a row is assigned a separate interval comparator 30 in which the signal interval assigned to the respective sensor pixel 12 is stored.
- An electronic one (not shown here) is used for the simultaneous detection of large objects or structures lying above the resolution limit
- the method on which the invention is based can also be used on 1-chip matrix color cameras and for the detection of objects or structures in moving and unmoving materials. It is particularly advantageous for the detection of thread-like contaminations on textile webs, in bulk flows of cotton flakes and similar applications in automatic optical quality control.
