The research project was promoted by the EC Eurostars section and entirely financed by MIUR.
The SAPHARI program is aimed at the development of a 3D ultrasonic Non Destructive Testing equipment.
This equipment will include the following elements:
- A 2D ultrasonic image acquisition equipment (Acquisition subsystem), which has been developed by DASEL as an evolution of an existing system. This equipment will include the means for the movement of the acoustic probe (motors and encoders).
- The comparison between the standard technology like piezoelectric probe with new acoustic technology like CMUT developed by the Roma3 University.
- A communication link between the 2D image acquisition equipment and an external computing hardware.
- A computing hardware, which could be based on GPU, and which is in charge to implement the algorithms for converting a set of 2D images into a 3D image.
- The algorithm for converting the set of 2D images into a 3D image (SAFT).
- Software for basic rendering, measuring and analysing the 3D image.
Several images obtained by scanning with an ultrasound array at different positions are combined to improve resolution in the movement direction. Individual images are obtained with the phased-array technique in real time with a specialized hardware. These images are combined with the SAFT technique implemented by software running in GPU hardware.
The research project funded by Lazio Innova deals with the problem of the areas subject to pollution control. In particular, the aim of the project was to verify the sections under the coasts and river bays. The project was carried out by a temporary group of different companies located in the roman area. Dune was in charge of analysing hyper-spectral and visible images in order to classify and mark the contaminated areas from the non-contaminated ones. It was also faced the problem of the quantitative measure of the image quality before performing its electronic storage. In addition to reconsidering the classic algorithms of surface segmentation through the brightness gradient we tried to define the procedures of innovative analyses. During the work implementation it were in fact introduced original classification algorithms based on the covariance matrix obtained in the different spectral bands and on the spatial components examination in the bi-dimensional transformed domain.
Research project funded by Lazio Innova. Dune has coordinated Research Centres and Universities.
The exploring activity of complex underground systems, natural or artificial, is often conditioned by access difficulty. In some cases, the very irregular walks of the paths, with twists and turns, bottlenecks and differences in altitudes influence both the outfitting necessary to frequent these locations and provide their documentation. In fact, it is to be taken into account the possibility that environmental conditions can limit or even completely prevent the use of electronic equipment inside the cave.
The Arianna system allows to provide a quick answer to this kind of problem. In fact, it is enough to perform a path inside the area to extract an expedition map of the location. When it happens to reach more than one time the same point it is possible to take advantage of this event to considerably improve the reconstructed map. The production of the map is obtained with the CTX tool software described in the area of interest of the ARIANNA product.
The research project funded by Lazio Innova deals with the problem of analysis, implementation and evaluation of registration algorithms in the field of three-dimensional and multi-modal medical images. Dune has coordinated the activities of a partner company and three scientific centres in the medical field. During the activity a reasonable number of registration algorithms for mono-modal images was evaluated. First of all the software implementation of a specific algorithm was described (Mutual Information, MI), selected both for its description in literature as a particular efficient algorithm and for its usability in the case of mono-modal and multi-modal images. Throughout the research further algorithms were also analysed: Correlation Ratio, CR and Normalized Gradient Field, NGF. All these algorithms were improved with the introduction of original ideas and implemented in SW using the C++ programming language. It was also included the section of interface regarding the images file management in DICOM format.

Project financed by Lazio Innova for the study and construction of CUBESAT 6U class satellites, designed to embed payloads for earth observation and remote sensing. The proposed payload is a passive GNSS-R reflectometer for the analysis of the soil condition, in particular of the humidity and biomass characteristics, flanked by a high-bit Banda Ka transmitter.
HORTA also proposes to study and implement a reception and processing center of data sent to the ground by CUBESAT, in order to offer a turnkey service to users, whether public or private. Dune deals with the development (HW and SW) of the payload as well as the communication systems in the UHF and S bands for the transmission of telemetry and payload data.

Project financed by Sicily Region is related to the development of an integrated system consisting of a ROV and a payload. Dune will collaborate with other companies (Tecnav, CNR and University of Palermo) for the development of the payload that creates an integrated vision of an acoustic and optical type. The acoustic system consists of two observation groups each one made by three receiving antennas. The elementary acoustic antenna will be constructed in such a way as to reduce to a minimum the number of electrical connections in respect of to the process electronics.
Dune will take care of the development of the acoustic data transmission / reception system and the beamformer management in order to produce the acoustic image of the environment. This image will be sent to the Man Machine Interface (MMI) section for the purpose of immediate visualization for the user and with the intent of making a fusion between this image and that coming from the optical sensor.
