Initial Evaluation of the Potential of Smartphone Stereo-Vision in Museum Visits

Abstract

<p><strong>Abstract.</strong> The recent introduction of new technologies such as augmented reality, machine learning and the worldwide spread of mobile devices provided with imaging, navigation sensors and high computational power can be exploited in order to drammatically change the museum visit experience. Differently from the traditional use of museum docents or audio guides, the introduction of digital technologies already proved to be useful in order to improve the interest of the visitor thanks to the increased interaction and involvement, reached also by means of visual effects and animations. Actually, the availability of 3D representations, augmented reality and navigation abilities directly on the visitor’s device can lead to a personalized visit, enabling the visitor to have an experience tailored on his/her needs. In this framework, this paper aims at investigating the potentialities of smartphone stereo-vision to improve the geometric information about the artworks available on the visitor’s device. More specifically, in this work smartphone stereo-vision will used as a 3D model generation tool in a 3D artwork recognition system based on a neural network classifier.</p>

The Influence of Interpolated Point Location and Density on 3D Bathymetric Models Generated by Kriging Methods: An Application on the Giglio Island Seabed (Italy)

“…Nowadays, 3D modeling is applied in many fields, such as cultural heritage preservation [1], underground survey [2], coastal monitoring [3], indoor mapping [4], quarry's studies [5], and landfill monitoring [6].…”

Bim for Museums: An Integrated Approach From the Building to the Collections

“…− designing new displays, temporary exhibitions or lighting design; − studying the handling of the art works; − calculating the loads on the floors and walls; − verifying the compatibility between the location of a piece and its microclimatic conditions; − managing the cleaning and maintenance of the works. In addition to these applications for museum management, there are other applications for communication and museum users, such as virtual or augmented reality applications that can take advantage of the presence of 3D models of works of art in the context of the building model (Masiero et al, 2019).…”

Assessment of a Portable Tof Camera and Comparison With Smartphone Stereo Vision

“…The characteristics of such two rear cameras (a "standard" and a "wide-angle" camera) of the LG G6 are reported in Table 2. The reader is referred to (Masiero et al, 2019) for a more detailed description of the approach used for stereo vision reconstruction with the images acquired with the dual camera of smartphone LG G6. sensor resolution 4160 pix × 3120 pix pixel physical side size 1.12 µm standard camera focal length 4.03 mm wide-angle camera focal length 2.01 mm baseline between cameras ≈ 1.8 mm Table 2. LG G6 characteristics)…”

“…Consequently, the ToF camera assessment and the comparison are done in the range of depths that can be interest for such combination. In practice, given the short baseline between the two cameras of the LG G6, reasonable 3D reconstruction results are possible only at quite low distances, e.g less than 1.5 m, approximately (Masiero et al, 2019).…”
