Monitoring ancient buildings: real deployment of an IoT system enhanced by UAVs and virtual reality
Bacco M., Barsocchi P., Cassarà P., Germanese D., Gotta A., Leone G. R., Moroni D., Pascali M. A., Tampucci M.
The historical buildings of a nation are the tangible signs of its history and culture. Their preservation deserves considerable attention, being of primary importance from a historical, cultural, and economic point of view. Having a scalable and reliable monitoring system plays an important role in the Structural Health Monitoring (SHM): therefore, this paper proposes an Internet Of Things (IoT) architecture for a remote monitoring system that is able to integrate, through the Virtual Reality (VR) paradigm, the environmental and mechanical data acquired by a wireless sensor network set on three ancient buildings with the images and context information acquired by an Unmanned Aerial Vehicle (UAV). Moreover, the information provided by the UAV allows to promptly inspect the critical structural damage, such as the patterns of cracks in the structural components of the building being monitored. Our approach opens new scenarios to support SHM activities, because an operator can interact with real-time data retrieved from a Wireless Sensor Network (WSN) by means of the VR environment.Source: IEEE access (2020). doi:10.1109/ACCESS.2020.2980359

Visible and infrared imaging based inspection of power installation
Jalil B., Pascali M. A., Leone G. R., Martinelli M., Moroni D., Salvetti O., Berton A.
The inspection of power lines is the crucial task for the safe operation of power transmission: its components require regular checking to detect damages and faults that are caused by corrosion or any other environmental agents and mechanical stress. During recent years, the use of Unmanned Autonomous Vehicle (UAV) for environmental and industrial monitoring is constantly growing and the demand for fast and robust algorithms for the analysis of the data acquired by drones during the inspections has increased. In this work, we use UAV to acquire power transmission lines data and apply image processing to highlight expected faults. Our method is based on a fusion algorithm for the infrared and visible power lines images, which is invariant to large scale changes and illumination changes in the real operating environment. Hence, different algorithms from image processing are applied to visible and infrared thermal data, to track the power lines and to detect faults and anomalies. The method significantly identifies edges and hot spots from the set of frames with good accuracy. At the final stage we identify hot spots using thermal images. The paper concludes with the description of the current work, which has been carried out in a research project, namely SCIADRO.Source: Pattern recognition and image analysis 29 (2019): 35–41. doi:10.1134/S1054661819010140

Architectural Heritage: 3D Documentation and Structural Monitoring Using UAV
Germanese D, Pascali M. A., Berton A., Leone G. R., Moroni D., Jalil B., Tampucci M., Benassi A.
Architectural heritage preservation and dissemination is a very important topic in Cultural Heritage. Since ancient structures may present areas which are dangerous or difficult to access, Unmanned Aerial Vehicles may be a smart solution for the safe and fast data acquisition. In this paper, we propose a method for the long term monitoring of cracking patterns, based on image processing and marker-based technique. Also the paper includes the description of a pipeline for the reconstruction of interactive 3D scene of the historic structure to disseminate the acquired data, to provide the general public with info regarding the structural health of the structure, and possibly to support the drone pilot during the survey. The Introduction provides a state of the art about the crack monitoring from visible images; it follows a description of the proposed method, and the results of the experimentation carried out in a real case study (the Ancient Fortress in Livorno, Italy). A specific section is devoted to the description of the front-end of augmented reality designed for heritage dissemination and to support the drone usage. Details about the future works conclude the paper.Source: Visual Pattern Extraction and Recognition for Cultural Heritage Understanding (VIPERC 2019), pp. 1–12, Pisa, January 30, 2019

Smart cities monitoring through wireless smart cameras
Moroni D., Pieri G., Leone G. R., Tampucci M.
Cities and urban environments nowadays suffer more and more discomfort due to several factors: the increase in the number of cars, the reduction, due to budget issues, of free parking, the economic difficulties in times of crisis that lead to a reduced efficiency of the public transport system. Beside these factors, an increased availability of computing facilities and devices bring the possibility to improve one of the most burdening aspects, that is the traffic generated by cars searching for a parking place. In this paper we present an approach based on wireless smart cameras to the monitoring of open air public parking areas. The main strengths of this solution lie in the independence and scalability of the proposed architecture. Independence is mainly based on autonomous intelligent cameras performing processing on-board; while scalability is mainly obtained through low cost single node which can be assembled in a wider sensors network and do not need high-cost requirements for installation.Source: 2nd International Conference on Applications of Intelligent Systems, Las Palmas de Gran Canaria, Spain, 07-09/01/2019

Parking Lot Monitoring with Smart Cameras
Amato G., Bolettieri P., Carrara F., Ciampi L., Gennaro C., Leone G. R., Moroni D., Pieri G., Vairo C.
In this article, we present a scenario for monitoring the occupancy of parking spaces in the historical city of Lucca (Italy) based on the use of intelligent cameras and the most modern technologies of artificial intelligence. The system is designed to use different smart-camera prototypes: where the connection to the power grid is available, we propose a powerful embedded hardware solution that exploits a Deep Neural Network. Otherwise, a fully autonomous energy-harvesting node based on a low-energy custom board employing lightweight image analysis algorithms is considered.Source: 5th Italian Conference on ICT for Smart Cities And Communities, pp. 1–3, Pisa, Italy, 18-20 September, 2019

Smart Cities: parking monitoring through smart cameras
Leone G. R., Moroni D., Pieri G.
One of today's major problems in medium to large cities is pollution caused by urban traffic. There are various factors that negatively affect this problem. First of all, the constant increase in vehicles, and at the same time the reduction, for budget reasons, of the number of free parking areas more or less easily reached. Moreover, due to global events such as the economic crisis, there is a general reduction in the efficiency of local public transport. In this research, we present an approach to this problem that exploits the greater availability of IT structures and devices. The solution presented offers the possibility of improving one of the most burdensome aspects, namely the traffic generated by cars looking for a parking space through an integrated and automatic management of employment levels. The procedure is based on wireless smart cameras for monitoring public outdoor parking areas. The main strengths of this solution lie in the independence and scalability of the proposed architecture. Independence is ensured by the node's modus operandi, in which processing is performed on board the intelligent camera without the need for a video stream or operator intervention. Scalability can be achieved by designing low-cost nodes that can be connected in a sensor network that does not require high installation costs. Moreover, the possibility of making such processing nodes autonomous through the use of a photovoltaic panel allows them to be installed in even more flimsy situations.Source: ICC Workshops 2019 - IEEE International Conference on Communications, pp. 1–6, Shanghai, China, 20-24 May, 2019

Metodologie di visione artificiale per la documentazione e il monitoraggio strutturale di costruzioni antiche mediante droni
Leone G. R., Germanese D., Moroni D., Pascali M. A., Tampucci M., Berton A.
La manutenzione e la salvaguardia del complesso patrimonio architettonico italiano rappresentano un'importante sfida che deve essere quotidianamente affrontata dalle soprintendenze e dalla amministrazioni locali e regionali. In quest'ambito, lo sviluppo delle tecnologie ICT può contribuire ad una gestione più efficiente e accurata del costruito storico. In questo intervento, si presenta un sistema di visione artificiale basato sull'utilizzo di droni che permette di monitorare lo stato di conservazione di edifici e strutture nel tempo, andando a quantificare l'entità di lesioni e ammaloramenti. Un frontend di realtà virtuale, ottenuto mediante tecniche fotogrammetriche, permette inoltre di visualizzare i dati trasmessi dal drone contestualmente ai dati raccolti da una rete di sensori wireless per il monitoraggio in situ delle strutture. Il sistema è stato testato in tre diversi casi di studio in Toscana.Source: Ital-IA 2019, primo Convegno Nazionale CINI sull'Intelligenza Artificiale, WORKSHOP AI for CULTURAL HERITAGE, Roma, 18-19 Marzo 2019

Towards multimodal surveillance for smart building security
Amato G., Barsocchi P., Falchi F., Ferro E., Gennaro C., Leone G. R., Moroni D., Salvetti O., Vairo C.
The main goal of a surveillance system is to collect information in a sensing environment and notify unexpected behavior. Information provided by single sensor and surveillance technology may not be sufficient to understand the whole context of the monitored environment. On the other hand, by combining information coming from different sources, the overall performance of a surveillance system can be improved. In this paper, we present the Smart Building Suite, in which independent and different technologies are developed in order to realize a multimodal surveillance system.Source: Proceedings (MDPI) 2 (2018). doi:10.3390/proceedings2020095

To identify hot spots in power lines using infrared and visible sensors
Jalil B., Pascali M. A., Leone G. R, Martinelli M., Moroni D., Salvetti O.
The detection of power transmission lines is highly important for threat avoidance, especially when aerial vehicle fly at low altitude. At the same time, the demand for fast and robust algorithms for the analysis of data acquired by drones during inspections has also increased. In this paper, different methods to obtain these objectives are presented, which include three parts: sensor fusion, power line extraction and fault detection. At first, fusion algorithm for visible and infrared power line images is presented. Manual control points describe as feature points from both images were selected and then, applied geometric transformation model to register visible and infrared thermal images. For the extraction of power lines, we applied Canny edge detection to identify significant transition followed by Hough transform to highlight power lines. The method significantly identify edges from the set of frames with good accuracy. After the detection of lines, we applied histogram based thresholding to identify hot spots in power lines. The paper concludes with the description of the current work, which has been carried out in a research project, namely SCIADRO.Source: MISSI 2018 - International Conference on Multimedia and Network Information System, pp. 313–321, Wroclaw, Poland, 11-14 September 2018

he use of Unmanned Aerial Vehicles (UAVs) for environmental and industrial monitoring is constantly growing. At the same time, the demand for fast and robust algorithms for the analysis of the data acquired by drones during the inspections has increased. In this paper we provide a concise survey about a peculiar case study: the monitoring of the high-voltage power grid which includes: (i) the detection of the power lines and of the electric towers along with their components more subject to wear and tear; (ii) the diagnosis of maintenance status. In this work different algorithms from image processing are applied to visible and infrared thermal data, to track the power lines and to detect faults and anomalies. We applied Canny edge detection to identify significant transition followed by Hough transform to highlight power lines.

Real-time smart parking systems integration in distributed ITS for smart cities
Alam M., Moroni D., Pieri G., Tampucci M., Gomes M., Fonseca J., Ferreira J., Leone G. R.
Intelligent Transportation Systems (ITS) have evolved as a key research topic in recent years, revolutionizing the overall traffic and travel experience by providing a set of advanced services and applications. These data-driven services contribute to mitigate major problems arising from the ever growing need of transport in our daily lives. Despite the progress, there is still need for an enhanced and distributed solution that can exploit the data from the available systems and provide an appropriate and real-time reaction on transportation systems. Therefore, in this paper, we present a new architecture where the intelligence is distributed and the decisions are decentralized. The proposed architecture is scalable since the incremental addition of new peripheral subsystems is supported by the introduction of gateways which requires no reengineering of the communication infrastructure. The proposed architecture is deployed to tackle the problem of traffic management inefficiency in urban areas, where traffic load is substantially increased, by vehicles moving around unnecessarily, to find a free parking space. This can be significantly reduced through the availability and diffusion of local information regarding vacant parking slots to drivers in a given area. Two types of parking systems, magnetic and vision sensor based, have been introduced, deployed, and tested in different scenarios. The effectiveness of the proposed architecture, together with the proposed algorithms, is assessed in field trials.Source: Journal of advanced transportation (Online) 2018 (2018). doi:10.1155/2018/1485652

Ultrageo
Righi M., Leone G. R., Magrini M., Martinelli M., Moroni D., Della Pina F., Guidi R.
Questo documento descrive il lavoro scientifico di ricerca e il suo sviluppo denominato "UltraGEO". UltraGEO e? il cuore di un'idea nata dal Laboratorio Segnali e Immagini (SILab) dell'Istituto di Scienza e Tecnologie dell'Informazione del Consiglio Nazionale delle Ricerche con sede a Pisa e dal Comune di Massa. UltraGEO si propone come un nuovo sistema per il controllo degli smottamenti del terreno e delle frane. Per la misura degli smottamenti questo progetto di R&D prevede la realizzazione di un prototipo costituito da una rete di nodi attivi e passivi. I nodi sono adattivi in base alle caratteristiche dell'ambiente dove sono inseriti: basati su marker grafici (nodi passivi) oppure basati su marker con basse emissioni di segnali elettromagnetici e/o acustici (nodi attivi). UltraGEO e? progettato per essere modulare e utilizzabile in zone difficilmente accessibili, anche dove non vi e? nessuna sorgente di energia elettrica e non e? possibile dotare il nodo di batterie e pannelli solari. UltraGEO ha caratteristiche che vertono alla semplificazione dell'installazione dei sensori rispetto alle attuali tecnologie, riducendone i costi e semplificandone l'utilizzo nel breve e lungo periodo.DOI: 10.5281/zenodo.1492760

MOSCARDO: prototipo software per il riconoscimento di immagini e ricostruzione 3D (P3.1)
Moroni D., Germanese D., Leone G. R., Pascali M. A:, Tampucci M.
L' obiettivo del documento è quello di fornire una descrizione del prototipo software per il riconoscimento e il monitoraggio a lungo termine della salute strutturale di alcuni siti storici: Fortezza Vecchia (Livorno) e Voltone (Livorno). L'approccio scelto per la detection e l'analisi degli ammaloramenti presenti sulle strutture di interesse è quello image-based, che sfrutta l'installazione di marker nei punti individuati come critici o significativi ai fini del monitoraggio. Tale approccio, se da un lato offre la possibilità di una misurazione ripetibile e accurata, dall'altro pone una sfida tecnologica di rilievo sul numero di marker da usare rispetto all'estetica del bene culturale. Inoltre, i dati raccolti (immagini, video) vengono utilizzati anche per la ricostruzione di un modello 3D dettagliato degli edifici storici in esame: la visualizzazione di acquisizioni effettuate in momenti temporali differenti consente un'immediata analisi preliminare di eventuali alterazioni riscontrate. Nella Sezione 2, sono descritti i marker "ArUco" utilizzati. Vengono riportati, inoltre, esempi di punti critici nei quali tali markers verranno installati. Nella Sezione 3, viene descritta brevemente la metodologia utilizzata, dalla calibrazione della camera utilizzata, all'acquisizione delle immagini e dei video mediante drone, all'elaborazione dei dati. Nella Sezione 4, sono riportate le istruzioni d'uso del software, con un esempio di utilizzo.Source: ISTI Technical reports, 2018

MOSCARDO - Metodi per il riconoscimento di immagini e ricostruzione 3D
Moroni D., Germanese D., Leone G. R. Pascali M. A., Tampucci M.
L'attività 3.3 prevede lo studio e l'applicazione di metodi di image processing e computer vision per: -l'analisi di crepe, ammaloramenti e spostamenti relativi che possano danneggiare l'integrità strutturale degli edifici presi in esame; -la ricostruzione 3D degli scenari di interesse; Per quanto riguarda l'analisi e il monitoraggio degli artefatti strutturali, sono stati studiati i diversi metodi, invasivi e non invasivi (o contact-less), presenti in letteratura, al fine di sostituire quello più classico ma anche più laborioso e soggetto ad errori: l'ispezione visiva. In seguito sono descritti nel dettaglio gli approcci studiati, da quelli più invasivi, che sfruttano ad esempio sensori e/o sonde applicati alla superficie di interesse, a quelli meno invasivi, basati su target riflettenti, fino a quelli contact-less, basati sul solo processamento di immagini acquisite mediante termocamere o camere che lavorano nello spettro del visibile. Per quanto riguarda gli aspetti di ricostruzione 3D, sono state studiate tecniche di fotogrammetria per la ricostruzione tridimensionale delle strutture da monitorare. In particolare, sono stati analizzati vari software e algoritmi di fotogrammetria disponibili sia open source sia commerciali. Fra i vari prodotti analizzati è stato scelto, vista la qualità del risultato prodotto di orientarci verso l'adozione del software Photoscan di Agisoft. Il software, prese in ingresso una serie di immagini, determina l'angolo di acquisizione di ogni immagine. Esso calcola dapprima una nuvola sparsa e, successivamente, una nuvola densa. È possibile intervenire manualmente sui punti delle nuvole per apportare qualche correzione. In seguito, viene creata la mesh tridimensionale a partire dalla nuvola densa e, a partire dalle immagini originali, viene e generata una opportuna texture che va a coprire la mesh 3D. Il deliverable è così strutturato: nella Sezione 3 sono illustrati gli scenari di interesse (il Voltone e la Fortezza Vecchia a Livorno) e i punti critici da monitorare; nella Sezione 4 è descritto il set-up di acquisizione delle immagini; la Sezione 5 è quella dedicata allo studio dei metodi di analisi e monitoraggio di fessure e crepe; nella Sezione 6 saranno invece esplorati i metodi di ricostruzione 3D.Source: Project report, MOSCARDO, Deliverable D3.3, 2018
