In this paper, we propose a DL framework for Point Cloud segmentation, which employs an improved DGCNN (Dynamic Graph Convolutional Neural Network) by adding meaningful features such as normal and colour. The approach has been applied to a newly collected DCH Dataset which is publicy available: ArCH (Architectural Cultural Heritage) Dataset. This dataset comprises 11 labeled points clouds, derived from the union of several single scans or from the integration of the latter with photogrammetric surveys. The involved scenes are both indoor and outdoor, with churches, chapels, cloisters, porticoes and loggias covered by a variety of vaults and beared by many different types of columns. They belong to different historical periods and different styles, in order to make the dataset the least possible uniform and homogeneous (in the repetition of the architectural elements) and the results as general as possible. The experiments yield high accuracy, demonstrating the effectiveness and suitability of the proposed approach.<\/jats:p>","DOI":"10.3390\/rs12061005","type":"journal-article","created":{"date-parts":[[2020,3,20]],"date-time":"2020-03-20T11:42:11Z","timestamp":1584704531000},"page":"1005","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":216,"title":["Point Cloud Semantic Segmentation Using a Deep Learning Framework for Cultural Heritage"],"prefix":"10.3390","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9160-834X","authenticated-orcid":false,"given":"Roberto","family":"Pierdicca","sequence":"first","affiliation":[{"name":"Dipartimento di Ingegneria Civile, Edile e dell\u2019Architettura, Universit\u00e0 Politecnica delle Marche, 60100 Ancona, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5523-7174","authenticated-orcid":false,"given":"Marina","family":"Paolanti","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, Universit\u00e0 Politecnica delle Marche, 60100 Ancona, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9160-1674","authenticated-orcid":false,"given":"Francesca","family":"Matrone","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Ambiente, del Territorio e delle Infrastrutture, Politecnico di Torino, 10129 Torino, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1714-4310","authenticated-orcid":false,"given":"Massimo","family":"Martini","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, Universit\u00e0 Politecnica delle Marche, 60100 Ancona, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0244-9322","authenticated-orcid":false,"given":"Christian","family":"Morbidoni","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, Universit\u00e0 Politecnica delle Marche, 60100 Ancona, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6582-2943","authenticated-orcid":false,"given":"Eva Savina","family":"Malinverni","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria Civile, Edile e dell\u2019Architettura, Universit\u00e0 Politecnica delle Marche, 60100 Ancona, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8893-9244","authenticated-orcid":false,"given":"Emanuele","family":"Frontoni","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Informazione, Universit\u00e0 Politecnica delle Marche, 60100 Ancona, Italy"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5930-2711","authenticated-orcid":false,"given":"Andrea Maria","family":"Lingua","sequence":"additional","affiliation":[{"name":"Dipartimento di Ingegneria dell\u2019Ambiente, del Territorio e delle Infrastrutture, Politecnico di Torino, 10129 Torino, Italy"}]}],"member":"1968","published-online":{"date-parts":[[2020,3,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"399","DOI":"10.5194\/isprs-archives-XLII-2-399-2018","article-title":"From 2D to 3D supervised segmentation and classification for cultural heritage applications","volume":"42","author":"Grilli","year":"2018","journal-title":"Int.
