Outline Activities
Research on ancient Roman hisotry of its town-planning and domestic architecture, closely based on the results of field surveys around town houses in Pompeii, Herculaneum and Ostia in Italy tracing the archaeological evidence for the Roman conquest and Romanization. It will provide a masterly synthesis of the results of recent research, integrating archaeological and literary evidence to produce a cogent and coherent picture of the way in which the Roman house and town-planning responded to socio-cultural influences.
Research on the history of techniques and stone-production in ancient and early-medieval quarries, closely based on the results of field works around site Akoris in Mid-Egypt.
Field survey on ancient cities on the Northern Africa
Research on the history of domestic architecuture in the historical area of Hagi city comparing the evidence coming from a design given entirely by measurement with literary evidence.

    keyword : Ancinet Rome, Pompeii, Ostia, City wall, domestic architecture
    1991.04Research on ancient Roman hisotry of its town-planning and domestic architecture, closely based on the results of field surveys around town houses and city walls of Pompeii and Ostia in Italy tracing the archaeological evidence for the Roman conquest and Romanization. It will provide a masterly synthesis of the results of recent research, integrating archaeological and literary evidence to produce a cogent and coherent picture of the way in which the Roman house and town-planning responded to socio-cultural influences..

    2001.04Reconstructive analysis on the history of techniques and stone-production in ancient and early-medieval quarries, closely based on the results of field works around site Akoris in Mid-Egypt. Theories on the origins of the stone-production affected by the relationship of Greek architecture to that of other cultures can be discussed in the light of evidence from tool-marked quarry pits..

Current and Past Project
  • Laser scanning of an ancient Roman town, Herculaneum including new excavated area, such as Villa di Paperi, and underground structure.
  • Revising the General Map of Ostia Antica, which has been drawn in 1950s by I. Gismondi and used widely by researchers nowadays, using up-to-date laser scanning technology.
  • From 26th August to 9th September, the architectural investigation of city wall has been carried out at Pompeii. In these 60 years, we find a famous and detailed research on Pompeian city wall of Maiuri in 1930 giving place to a more sporadic and limited style of investigation and excavation, of which the Tower VIII by C. Trerre is the best-published example. Seeds of an architectural approach were sown under J. -P. Adam, but no project involving the whole city wall was undertaken. It is clear that one the chief reasons for this style was below. The city wall is so long and tall that researchers could not measure the whole city wall using traditional and old-fashioned equipments. All of the hitherto unpublished investigations are so fragmentary as to be impossible to grasp the measure of difference between the Roman and pre-Roman architectural details. Based on the research of Maiuri in 1930, the investigation consists of a peace by peace analysis which is intended to facilitate the discussion of whole city wall and urbanization sequences of Pompeii. In this investigation we introduce the most advanced measuring method: 3D scanning system, in which more than 10,000 scanning laser beams can be emitted in one second and the object can be described as the aggregation of dots having three dimensional coordinates. The measuring of whole city wall has been completed within two weeks. The whole city wall was separately measured into more than 200 aggregations of more than million dots. All of aggregations have to be combined in Japan into a whole three dimensional model near feature.
  • In general survey and archaeological excavation around Tehneh village in Egypt, which has been carried out from 1980, including ancient city Akoris, we intend to make clear the structure of urban industry, such as quarry and leather craft from the late Pharaonic to Roman periods.

Hori, DETECTION OF RESTORATION WORK BY APPLYING THE RANSAC ALGORITHM TO THE POINT CLOUD DATA FROM LASER SCANNING: CASE STUDY AT OSTIA, Remote Sensing and Spatial Information Sciences, https://doi.org/10.5194/isprs-archives-XLVI-2-W1-2022-315-2022, XLVI-2, W1, 315-321, 2022.02, In Ostia, the huge range of excavation carried out by Guido Calza under Mussolini (1938-1942), the zone of contiguous city blocks unearthed in those massive campaigns. From 2012, new survey by a Japanese team of standing remains using laser scanners formed the basis for an analysis of building history, and for a reconstruction of the original building. There is a considerable amount of undocumented reconstruction work in the upper part of the structure which has been identified from analysis of the surface of the walls. The seam and the absence of coursing between the original walls and the later restored works sometimes including in the Roman phase, and sometimes modern using original part of the walls, make difficult to identify which part of walls were original and which were restorations or re-use 80 years later from the excavation. In this paper, the case that the seams are invisible, but its existence is known from the photographic record of the progress of the excavations. The detection by applying the RANSAC algorithm to the point cloud data from laser scanning relies on several cases of invisible seams running on the surfaces. Additionally, this method allows us without any special knowledge and experience to find detailed characteristics on the surface of the walls, such as slight unevenness or weathering parts, to extrapolate the building history..
2. Ogawa,T., and Hori,Y., Comparison with Accuracy of Terrestrial Laser Scanner by Using Point Cloud Aligned with Shape Matching and best Fitting Methods, Remote Sensing and Spatial Information Sciences, https://doi.org/10.5194/isprs-archives-XLII-2-W9-535-2019, XLII-2, W9, 535-541, 2019.02, Recently operation systems of laser scanning have been obviously improved; for instance shape matching has been equipped with software on a post processing stage so measurement without any targets is a prerequisite condition of field surveying with laser scanners. Moreover a shape matching method enables us to easily register a pair of point clouds with some errors even if those data are scanned by several type scanners. Those slightly errors can influence accuracy of alignments if the object is large to require a lot of scans. Laser scanning data has random errors and accuracy of alignments can be improved by matching error distributions of pairs of point clouds to natural distributions. This method is called “best fitting” in contrast “shape matching” in a software, PolyWorks |Inspector. In this paper, accuracy of alignments between shape matching and best fitting is discussed. The scan data of three phaseshift laser scanners (FARO Focus 3D MS120, FARO Focus 3D X330 and Z+F Imager 5016) and two time-of-flight scanners (Leica BLK 360 and Leica Scan station C5) are used for analyses. Accuracy of alignments by using shape matching and best fitting methods is demonstrated by showing points of scan data with histograms of error distributions..

Awards
  • New investigations and re-examinations of older data applying the latest technology of laser scanning for more accurate measurements, afford not only fresh insights into ancient Roman buildings and urbanisation, but also new information that may lead to provide clues as to new research.
    Firstly, general maps retained in popular usage in Pompeii and Ostia were revised. The extreme resolution was sufficient to provide the comprehensive data required to create the sections and elevations, even general maps, in which large differences were confirmed to early drawings. Accurate records are essential for research and the incorrect records could eventually lead us to not only loss of new study opportunity but also incorrect results.
    Secondary, large data sets of point clouds with terrestrial scans allowed us to makes functional analyses of ancient Roman buildings and cities through reverse engineering processes possible, such as the design of the streets and sewers in Pompeii, the production process of a mosaic in the House of the Dioscuri at Ostia, the layout of mosaics in the Insula of Muse at Ostia, the topographical surveys of Ostia and its planning process, the traffic system of vehicles in Pompeii, and the construction process of the Capitolium in Ostia.
