Title
(EN) 3D IMAGE ENHANCEMENT FOR FLAW DETECTION
(FR) ACCENTUATION D'IMAGES 3D POUR DÉTECTION DE DÉFAUTS
Abstract
(EN) Examples of the present subject matter provide techniques for enhancing images taken from non-destructive inspection techniques, such as acoustic inspection. A source 3D data may be acquired representing an object. Rather than displaying the source 3D data, signal processing may be employed to enhance the flaws or defects in the source 3D data. A geometry template of the object may be created using the source 3D data. The source 3D data may be compared to the geometry template, and based on the comparison, an enhanced 3D image may be generated.
(FR) La présente invention concerne, dans certains exemples, des techniques destinées à accentuer des images prises à partir de techniques d'inspection non destructive, telles que l'inspection acoustique. Des données 3D de source représentant un objet peuvent être acquises. Plutôt que d'afficher les données 3D de source, un traitement de signal peut être employé pour accentuer les défauts ou imperfections dans les données 3D de source. Un modèle de géométrie de l'objet peut être créé à l'aide des données 3D de source. Les données 3D de source peuvent être comparées au modèle de géométrie et, d'après la comparaison, une image 3D accentuée peut être générée.
