Article
Full-text available
Video surveillance camera (VSC) is an important source of information during investigations especially if used as a tool for the extraction of verified and reliable forensic measurements. In this study, some aspects of human height extraction from VSC video frames are analyzed with the aim of identifying and mitigating error sources that can strong...

Powerline inspection is an important task for electric power management. Corridor mapping, i.e., the task of surveying the surroundings of the line and detecting potentially hazardous vegetation and objects, is performed by aerial light detection and ranging (LiDAR) survey. To this purpose, the main tasks are automatic extraction of the wires and m...

The Advanced Virgo (AdV) detector is a 3 km long arms Michelson interferometer for gravitational waves detection. The management of a complex and large research infrastructure requires high-precision geodetic surveying for positioning and rearrangement of instruments. This paper describes the establishment of Virgo Reference System (VRS) consisting...

Horizontal levels are references entities, the base of man-made environments. Their creation is the first step for various applications including the BIM (Building Information Modelling). BIM is an emerging methodology, widely used for new constructions, and increasingly applied to existing buildings (scan-to-BIM). The as-built BIM process is still...

Rome is the city where two different cultures have found their greatest architectural achievement, the Latin civilization and the Christian civilization. It is for this reason that in Rome there is the greatest concentration in the world of Roman buildings, monuments and Christian buildings and churches. Rome is the seat of the papacy; say the head...
Article
On the Aventine Minor, the oratory of Santa Silvia was home to a community of oriental monks, who, in the first half of the seventeenth century, created a typical Palestinian cemetery with a small monastery that expanded with the growing prestige of the community. The construction of the Basilica of San Saba, above the oratory, was by a group of mo...

Unmanned aerial vehicle-based LiDAR survey provides very-high-density point clouds, which involve very rich information about forest detailed structure, allowing for detection of individual trees, as well as demanding high computational load. Single-tree detection is of great interest for forest management and ecology purposes, and the task is rela...

Among the several information available on web the spherical panoramas by Google can be an important reference for the 3D models elaboration of urban contexts and historic buildings, difficult to access or even destroyed as a result of wars or natural disasters. Starting from the spherical photogrammetry, thoroughly tested and used by some scholars...

In order to improve the observation capability in one of the most active volcanic areas in the world, Mt. Etna, we developed a processing method to use the surveillance cameras for a quasi real-time mapping of syn-eruptive processes. Following an evaluation of the current performance of the Etna permanent ground NEtwork of Thermal and Visible Senso...
Article
The objective of this paper is to highlight current trends in photogrammetry, trying to foresee where they will lead the discipline in the next years. To this aim, first some remarks on the challenges brought to photogrammetry by other sensors and a brief historical survey of some research topics, where an increasing convergence between photogramme...

Full-text available
We present the first step of a research aimed at automating a driven interactive 3D modeling of an existing architectural object. The method is based on oriented multi-image spherical panoramas produced by stitching techniques. The photogrammetric process has two steps: the creation of a semi-automatic process to find homolog points in two panorama...

In volcanic areas, where it can be difficult to perform direct surveys, digital photogrammetry techniques are rarely adopted for routine volcano monitoring. Nevertheless, they have remarkable potentialities for observing active volcanic features (e.g., fissures, lava flows) and the connected deformation processes. The ability to obtain accurate qua...

Full-text available
In this work, a simple methodology is presented for processing high-resolution topographical data over wide areas. It is based on digital elevation model of differences (DEMoD) among high-resolution digital models (HRDEM) produced from lightdetection and ranging (LiDAR) data. Because these qualitative approaches based on HRDEMs can be affected by e...

In this work the performance of UAV-based photogrammetry for 3D building modeling was evaluated, by comparison with ground LiDAR data. In particular it shows that accuracy of the photogrammetric model is in the order of 0.1m globally, and better than 0.05m for local measurements.

Panoramic images have increasingly interesting applications and they are extensively used for cultural heritage documentation and virtual 3D environments. Moreover, it has been proven that they can contain good metric content. This paper describes a state-of-the-art photogrammetric tool based on spherical panoramas. The fundamental photogrammetric...

Filtering non-terrain points from raw laser scanning data is the most important goal to improve productivity in DTM generation. Filtering algorithms are built on assumptions about what discriminates terrain points from points on other objects (e.g. buildings and vegetation). In most cases, a single measure is used to accept or reject points. In thi...

A consortium called Mutatis Mutandis (MutMut), consisting of three Universities and eight producers and users of geo-information, was established in the Netherlands to streamline change detection on a national level. After preliminary investigations concerning market feasibility, three actions are being taken by MutMut: (1) construction of a centra...

Automated approaches to building detection in multi-source aerial data are important in many applications, including map updating, city modeling, urban growth analysis and monitoring of informal settlements. This paper presents a comparative analysis of different methods for automated building detection in aerial images and laser data at different...
Article
Airborne laser scanning is today the most effective data acquisition technology for the production of high resolution, high quality DTMs (Digital Terrain Models). The only competing technique might be aerial photogrammetry with direct camera orientation by GPS/INS (Inertial Navigation Systems) and DTM generation by digital image correlation; with a...

Automated approaches to building detection are of great importance in a number of different applications including map updating and monitoring of informal settlements. With the availability of multi-source aerial data in recent years, data fusion approaches to automated building detection have become more popular. In this paper, two data fusion met...
Conference Paper
Automatic building detection has been a hot topic since the early 1990’s. Early approaches were based on a single aerial image. Detecting buildings is a difficult task so it can be more effective when multiple sources of information are obtained and fused. The objective of this paper is to provide a comparative analysis of automatic approaches to b...

A strategy for building reconstruction relying on LIDAR data only is presented. Roofs are modeled as plane surfaces, connected along ridges and bordered by the eaves lines. Edge pixels and plane surfaces are detected and labelled as roof slopes based on gradient orientation and plane fitting by RANSAC; a similar procedure applies to eaves lines. Ba...
