METHOD AND APPARATUS FOR DETECTION OF FOREIGN OBJECT DEBRIS

摘要

A method and a system for the detection of Foreign Object Debris (FOD) on a surface of a transport infrastructure are described. The method comprises receiving 3D profiles of the surface from at least one 3D laser sensor, the 3D laser sensor including a camera and a laser line projector, the 3D laser sensor being adapted to be displaced to scan the surface of the transport infrastructure and acquire 3D profiles of the surface; analyzing the 3D profiles using a parametric surface model to determine a surface model of the surface; identifying pixels of the 3D profiles located above the surface using the surface model; generating a set of potential FOD by applying a threshold on the pixels located above the surface model to identify a set of at least one protruding object; providing detection information about the potential FOD.
