“…It is especially in the field of AR that you can find various tools for online viewing and editing of the photogrammetric model. These tools can help some professionals with dissemination and documentation in the field of CH, for purposes such as the creation of virtual museums or remote knowledge of archaeological sites that are not so well known or are difficult to reach [33][34][35][36]. The use of drones in this field is not limited to 3D modelling only, but is a powerful tool to virtually visit the area of interest.…”

The unmanned aerial vehicle (UAV) photogrammetric survey of an archaeological site has proved itself to be particularly efficient. In order to obtain highly accurate and reliable results, it is necessary to design carefully the flight plan and the geo-referencing, while also evaluating the indicators of the accuracy rate. Using as a test case a UAV photogrammetric survey conducted on the archaeological site of the Roman Amphitheatre of Avella (Italy), in this paper, we propose a pipeline to assess the accuracy of the results according to some quality indicators. The flight configuration and the georeferencing chosen is then be checked via the residuals on the ground control points (GCPs), evenly distributed on the edges and over the entire area. With the aim of appraising the accuracy of the final model, we will suggest a method for the outlier detection, taking into account the statistical distribution (both global and of portion of the study object) of the reprojection errors. A filter to reduce the noise within the model will then be implemented through the detection of the angle formed by homologous rays, in order to reach a compromise between the number of the usable points and the reduction of the noise linked to the definition of the 3D model.

“…Collaborative geometry learning based object constructions shown in Fig. 1 is an active area for the researchers which includes augmented reality by hybrid hardware and software setup [18] [47]. However, requirement of comprehensive evaluation of the practical value such as development of substantial educational content demands for further investigation for real use in the classroom for teachers or students.…”

“…By interacting with 3D objects in virtual reality, users get a better understanding of the subject matter. The primary requirement for these projects is expertise in 3D geometry modeling and then designing operational procedures for users or participants and observing user activity and documentation of feedback [32] [33] [47]. Investigating students understanding of the topic before going into development of the project is suggested by researchers, since that allows researchers to get to know their participants perspective better.…”

3D gesture recognition and tracking based augmented reality and virtual reality have become a big interest of research because of advanced technology in smartphones. By interacting with 3D objects in augmented reality and virtual reality, users get better understanding of the subject matter where there have been requirements of customized hardware support and overall experimental performance needs to be satisfactory. This research investigates currently various vision based 3D gestural architectures for augmented reality and virtual reality. The core goal of this research is to present analysis on methods, frameworks followed by experimental performance on recognition and tracking of hand gestures and interaction with virtual objects in smartphones. This research categorized experimental evaluation for existing methods in three categories, i.e. hardware requirement, documentation before actual experiment and datasets. These categories are expected to ensure robust validation for practical usage of 3D gesture tracking based on augmented reality and virtual reality. Hardware set up includes types of gloves, fingerprint and types of sensors. Documentation includes classroom setup manuals, questionaries, recordings for improvement and stress test application. Last part of experimental section includes usage of various datasets by existing research. The overall comprehensive illustration of various methods, frameworks and experimental aspects can significantly contribute to 3D gesture recognition and tracking based augmented reality and virtual reality.
