Immersive virtual model accuracy and user perception: preliminary results of a case study with low cost photogrammetric survey method by drone

In this research, photogrammetry is coupled with Virtual Reality to model a complex architecture case with the aim to assess the correlation between the dense point clouds and the quality of the immersive virtual scenarios upon varying the number of the points of the clouds. The visual quality of the virtual reality scenarios was evaluated by subjective assessment. The results underline that the higher the number of points is and better is the visual quality of the virtual model perceived by people.
