The EyeVision 3D image processing software has a special command set to scan profiles, to do meas-urements based on those profiles and check if there is an error on those profiles. As it is a 3D profile, this means that the point are not only captured in their x- and y-directions but also their position in z-direction. Therefore the scan can also generate a point cloud image in addition to the profile image. For this task a laser triangulation or stereo vision sensor is necessary. The laser line scans the object and a camera takes the image of the laser line and a profile is issued.
A profile measurement is important for various different applications for quality checks during the production process. When scanning a weld seam, it can be checked if it there are flaws in the seam, such as e.g. cracks, holes, inclusions, lack of fusion, incomplete penetration, deviation in dimension or shape, etc.
