The paper deals with the relevance of using laser-plane sensors in 3D part inspection. First, based on the evaluation of the measuring system capacities, a digitizing strategy permits to obtain a set of points with a sufficient quality as regards geometrical specifications. Despite the optimized strategy, the digitizing noise associated to the sensor alters data quality, and may affect the estimation...
For each scanned object 3D triangulation laser scanners deliver multiple sweeps corresponding to multiple laser motions and orientations. The problem of aligning these scans has been well solved by using rigid and, more recently, non‐rigid transformations. Nevertheless, there are always residual local offsets between scans which forbid a direct merging of the scans, and force to some preliminary smoothing...
