  • Patent number: 11555694
    Abstract: A method for controlling a laser profiler, the laser profiler being configured for generating a laser line on a surface to be inspected, the method comprising: receiving an image of the laser line; determining an actual intensity of the laser line; calculating an amplification factor for the laser line based on the actual intensity of the laser line, a target intensity for the laser line, a power of the laser, a camera gain of the camera and an exposure time of the laser line on the surface to be inspected, the amplification factor allowing the actual intensity of the laser line to reach the target intensity while minimizing the power of the laser; and based on the calculated amplification factor, adjusting at least one parameter of the laser profiler so that the actual intensity of the laser line corresponds to the target intensity.

  • Publication number: 20140375770
    Abstract: 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.
