Item inspection by dynamic selection of projection angle

摘要

Disclosed are methods, systems, use and computer program products for inspection of articles.The method (1) isObtaining projected images of articles using radiation imaging system (2)A plurality of simulation projected images of an article or its components are obtained based on a simulation of a numerical three-dimensional model, andAt least one geometrical parameter for the relative orientation between the simulation article and the simulated radiation source and the simulation detection plane is assumed to be different over multiple simulation images.The method comprises (4) determining the relative orientation of the article to the imaging system, and the relative orientation determination comprises comparing the projected image with a plurality of simulated images.The method is to determine at least one rotation angle in consideration of the viewing angle and relative orientation (5) and to move the article and / or imaging system in accordance with at least one rotation angle (6) and to obtain further projected images of the article after movement of the article (7) A further projected image corresponds to the figure of the article from the viewing angle.
