摘要
In recent years, the use of Image-Based Modeling (IBM) and Structure from Motion (SfM) photogrammetric techniques is increasing in the area of surveying. The quality parameters of this type of survey, widely practiced, are not today univocally defined. In fact, in order to be tested, metric quality often requires comparison with the acquisitions made with other technologies and, at the same time, the definition of color quality is a field still little explored, although it provides significant information content. The experimentation presented is aimed at finding a methodology for measuring the quality of an image-based model, with particular reference to chromatic definition, expressed in terms of overall sharpness and resolution. The proposed algorithm, which is general and therefore valid regarding any subject whatever the shooting conditions, must be understood as a basis for discussion about this significant issue and as an invitation to explain the construction processes at the basis of the realization of these types of models.
