Method for detecting the bad positioning and the surface defects of specific components and associated detection device

摘要

A method for detecting the bad positioning and the surface defects of a specific component of a vehicle in motion, comprising:
- scanning the region surrounding a specific component of a vehicle in motion on a rail road to obtain a three dimensional representation of the region surrounding the specific component,
- aligning the three dimensional representation with a surrounding three dimensional model of the region surrounding the specific component to obtain a roughly aligned three dimensional representation,
characterized in that, the method also comprises :
- aligning the roughly aligned three dimensional representation with a specific three dimensional model of the specific component to obtain an accurately aligned three dimensional representation and an accurate rigid transformation, and
- analyzing the bad positioning and the surface defects of the specific component.
