Method for classifying casting defects within the framework of an X-ray analysis

Abstract

The invention relates to a method for classifying casting defects in a casting within the framework of an X-ray analysis, wherein the casting defects are each automatically allocated to a known casting defect type by comparing the X-ray image of the casting with features from training images of known casting defect types and the casting defects present in the examined casting are thus established.

1 . Method for classifying casting defects in an examined casting having a casting defect within the framework of an X-ray analysis comprising: 
 acquiring an X-ray image of the examined casting;    automatically comparing the X-ray image of the examined casting with features from training images of known casting defect types; and automatically allocating the casting defects present in the examined casting to a known casting defect type.    
     
     
         2 . Method according to  claim 1 , characterized in that the known casting defect types are grouped into classes that have comparable features in the X-ray image.  
     
     
         3 . Method according to  claim 2 , characterized in that classes with comparable features in the X-ray image are grouped into superclasses.  
     
     
         4 . Method according to  claim 3 , characterized in that still further groupings take place on one or several levels.  
     
     
         5 . Method according to  claim 2 , characterized in that the classification is based on a decision tree which is used to proceed from the abstract superclasses or classes with simple features to the specific casting defect with complex features.  
     
     
         6 . (canceled)  
     
     
         7 . Method according to  claim 3 , characterized in that the classification is based on a decision tree which is used to proceed from the abstract superclasses or classes with simple features to the specific casting defect with complex features.  
     
     
         8 . Method according to  claim 4 , characterized in that the classification is based on a decision tree which is used to proceed from the abstract superclasses or classes with simple features to the specific casting defect with complex features.  
     
     
         9 . Method according to  claim 1 , characterized in that, once the specific casting defect has been automatically recognized, the casting process is automatically controlled and the parameters of the casting process are automatically modified according to the recognized casting defect.  
     
     
         10 . Method according to  claim 2 , characterized in that, once the specific casting defect has been automatically recognized, the casting process is automatically controlled and the parameters of the casting process are automatically modified according to the recognized casting defect.  
     
     
         11 . Method according to  claim 3 , characterized in that, once the specific casting defect has been automatically recognized, the casting process is automatically controlled and the parameters of the casting process are automatically modified according to the recognized casting defect.  
     
     
         12 . Method according to  claim 4 , characterized in that, once the specific casting defect has been automatically recognized, the casting process is automatically controlled and the parameters of the casting process are automatically modified according to the recognized casting defect.  
     
     
         13 . Method according to  claim 5 , characterized in that, once the specific casting defect has been automatically recognized, the casting process is automatically controlled and the parameters of the casting process are automatically modified according to the recognized casting defect.  
     
     
         14 . Method according to  claim 7 , characterized in that, once the specific casting defect has been automatically recognized, the casting process is automatically controlled and the parameters of the casting process are automatically modified according to the recognized casting defect.  
     
     
         15 . Method according to  claim 8 , characterized in that, once the specific casting defect has been automatically recognized, the casting process is automatically controlled and the parameters of the casting process are automatically modified according to the recognized casting defect.
