1. A computer-implemented method comprising:
obtaining a metrology data set that represents an article in a metrology coordinate system;
obtaining a build data set that represents the article in a build coordinate system;
determining a surface geometry of the article that is present in the metrology data set and the build data set;
selecting a metrology data subset from the metrology data set that represents the surface geometry of the article;
selecting a build data subset from the build data set that represents the surface geometry of the article;
generating a metrology point cloud from the metrology data subset in the metrology coordinate system;
generating a build point cloud from the build data subset in the build coordinate system;
pre-aligning the metrology point cloud and the build point cloud;
registering the metrology point cloud and the build point cloud;
calculating a transform between the metrology coordinate system and the build coordinate system;
applying the transform to the metrology data set to convert the metrology data set to the build coordinate system;
detecting a defect in the article represented by the metrology data set in the metrology coordinate system; and
determining a location of the defect in the build coordinate system.
