Metrology is defined by the International Bureau of Weights and Measures (BIPM) as "the science of measurement, embracing both experimental and theoretical determinations at any level of uncertainty in any field of science and technology". Within various project with private companies, we applied precise and reliable measurements - based on close-range photogrammetry or triangulation laser scanning - for monitoring, manufacturing, quality control, inspection and product development. In particular, our aim is to deliver innovative 3D inspection and monitoring solutions, based on photogrammetric methods, for quality control of industrial pieces. We focus on non-collaborative textureless surfaces, generally problematic for inspections based on optical methods. Efforts are intended to (i) test the metric performance of the automated photogrammetric 3D reconstruction procedure, (ii) enhance the accuracy of the final results, (iii) obtain statistical indicators and (iv) develop quality control procedures useful to industries. Optical metrology methods are exploited to integrate their main functionalities (centroid measurement, photogrammetric network design, bundle adjustment, precision assessment, etc.) into a pipeline for 3D inspection and quality control. Metrological standards (e.g. VDI/VDE guidelines) are also followed.
