Registration of Feature-Poor 3D Measurements from Fringe Projection

We propose a novel method for registration of partly overlapping three-dimensional surface measurements for stereo-based optical sensors using fringe projection.Based on two-dimensional texture matching, it virginia mill works tobacco road acacia allows global registration of surfaces with poor and ambiguous three-dimensional features, which are common to surface inspection applications.No prior information about relative sensor position is necessary, which makes our approach suitable for amina muaddi scarpe trasparenti semi-automatic and manual measurement.The algorithm is robust and works with challenging measurements, including uneven illumination, surfaces with specular reflection as well as sparsely textured surfaces.

We show that precisions of 1 mm and below can be achieved along the surfaces, which is necessary for further local 3D registration.
