Abstract.  A novel reconstruction scheme using ultraviolet (UV) structured point for transparent objects three-dimensional (3D) measurement was reported in our previous works. We address two main approaches behind a low-cost system within two suggested configurations (according to the structured light generation source: UV spot and UV line) in order to improve the results accuracy, which endows our system with its adaptability for industrial applications. The first approach consists of determining the optimal configuration of the practical setup while controlling the modeling error (related to the 3D reconstruction approach) with the implementation of an additional validation method in the reconstruction process. The second approach deals with a method which tracks the fluorescence points in the presence of noises inherent to our acquisition system. The specificity of the implemented tracking method relies on spectroscopic analysis. Indeed, experimental investigation has been also carried out to characterize the application. Some digitized objects are presented with an accuracy never reached by any previously reported works dealing with the digitization of transparent objects without any prior preparation.
