<p><strong>Abstract.</strong> This paper presents the most recent developments in a project aimed to the documentation, storage and dissemination of the cultural heritage. The subject of the project are more than 70 Baroque atria in Turin, recognized by critics for their particular unitary vaulted systems Our research team is currently working on digitizing documents and studying ways to enhance and share these results through ICT. In particular, we want to explore possibilities for recognizing and tracing three-dimensional objects in augmented reality (AR) applications connected to the collected data. Recent developments in this field relate to the technology available on widespread mobile devices such as tablets and smartphones, allowing for real-time 3D scanning. Using software prototypes, we want to introduce some problems involved in integrating this technology into digital archives.</p>

Tomographic Data

Current functional neuroimaging methods are not adequate for high-resolution whole-brain visualization of neural activity in real time. Here, we show imaging of fast hemodynamic changes in deep mouse brain using fully noninvasive acquisition of five-dimensional optoacoustic data from animals subjected to oxygenation stress. Multispectral video-rate acquisition of three-dimensional tomographic data enables simultaneous label-free assessment of multiple brain hemodynamic parameters, including blood oxygenation, total hemoglobin, cerebral blood volume, oxygenized and deoxygenized hemoglobin, in real time. The unprecedented results indicate that the proposed methodology may serve as a powerful complementary, and potentially superior, method for functional neuroimaging studies in rodents.

Object Of Study

The integration of physical reality and layers of digital information in real time can be diverse (text, symbols, audio, video, and/or three-dimensional objects) with the result of enriching or altering the information of the physical reality. It is also usual in the everyday context of citizens. In other words, augmented reality has been used for years, for example, to mark an offside game in football or to alter the face in real time. Regarding the computer and mobile applications, they are those related to the AR, and it is an increasingly widespread technology in the daily environment with potential in the educational field. Educational software creators have noticed that teachers can make a didactic use of AR technology in the classroom. Beyond contributing to educate in a responsible use of AR, with an adequate didactic approach, AR implies important advantages such as improving of motivation, participation, commitment to the object of study, teamwork, and procedure improvement.

Set Up

Three-dimensional objects can be scanned by 3D laser scanners that use active triangulation. These scanners create three-dimensional point clouds from the scanned objects. The laser line is identified in the images, which are captured at given transformations by the camera, and the point cloud can be calculated from these. The hardest challenge is to construct these transformations so that most of the surface can be captured. The result of a scanning may have missing parts because either not the best transformations were used or because some parts of the object cannot be scanned. Based on the results of the previous scans, a better transformation plan can be created, with which the next scan can be performed. In this paper, a method is proposed for transforming a special 3D scanner into a position from where the scanned point can be seen from an ideal angle. A method is described for estimating this transformation in real-time, so these can be calculated for every point of a previous scan to set up a next improved scan.
