“…Underground mapping of pipe networks have been a topic of interest in the past several years now. Most of the pipe detection and mapping is done over the ground using ground penetrating radar (GPR) such as presented in [1][2][3]. However, dealing with open ditches with visible pipe networks is a different issue.…”

Automatic and accurate mapping and modeling of underground infrastructure has become indispensable for several important tasks ranging from urban planning and construction to safety and hazard mitigation. However, this offers several technical and operational challenges. The aim of this work is to develop a portable automated mapping solution for the 3D mapping and modeling of underground pipe networks during renovation and installation work when the infrastructure is being laid down in open trenches. The system is used to scan the trench and then the 3D scans obtained from the system are registered together to form a 3D point cloud of the trench containing the pipe network using a modified global ICP (iterative closest point) method. In the 3D point cloud, pipe-like structures are segmented using fuzzy C-means clustering and then modeled using a nested MSAC (M-estimator SAmpling Consensus) algorithm. The proposed method is evaluated on real data pertaining to three different sites, containing several different types of pipes. We report an overall registration error of less than 7 % , an overall segmentation accuracy of 85 % and an overall modeling error of less than 5 % . The evaluated results not only demonstrate the efficacy but also the suitability of the proposed solution.

“…Pregled uporabe geofizikalnih metod pri geomorfoloških raziskavah sta podala Schrott & Sass (2008) in poudarila pomen integracije različnih metod ter opisala njihove prednosti in omejitve. V zadnjih nekaj letih so bili objavljeni tudi pregledni članki na področju gradbeništva (Wai-Lok Lai et al, 2018). Zajícová & Chuman (2019) sta podala pregled uporabe georadarja v študijah tal, kjer obravnavata določevanje vsebnosti vode, stratigrafije tal, vsebnosti soli in strukture tal, zaznavanje drevesnih korenin in koreninske biomase.…”

Kras kot kompleksen in heterogen sistem predstavlja za georadar velik izziv. Kljub vsemu pa lahko z dobro načrtovanimi georadarskimi raziskavami pridobimo dodatne informacije o plitvem podpovršju, kjer se odvija večina kraških procesov. Zaradi specifičnosti kraškega površja so v uvodnem delu predstavljene nekatere ovire in prilagoditveni pristopi pri raziskavah na krasu. Analiza pregleda objavljene literature je pokazala, da se georadar v kraških okoljih najpogosteje uporablja za zaznavanje jam in območij pogrezanj ter pri preprečevanju nenadnih porušitev tako v urbanih območjih kot tudi pri gradbenih posegih v prostor. Georadar se uporablja tudi pri raziskavah kraških vodonosnikov, epikrasa in raziskavah v kamnolomih. Poleg uveljavljenih aplikacij so predstavljene nekatere še neuveljavljene aplikacije, kot je uporaba georadarja pri raziskavah brezstropih jam in jamskih sedimentov. Glavni namen članka je prikazati in ovrednotiti možnosti uporabe georadarja v različnih kraških okoljih in spodbuditi njegovo uporabo za nekatere nove aplikacije in opozoriti na nujnost interdisciplinarnega pristopa v takšnih študijah.

“…Nas últimas décadas, o desenvolvimento de equipamentos e processamento de dados obtidos na aplicação de GPR permitiu que esta técnica evoluísse de uma mera visualização e inspeção expedita do terreno para a imagiologia de elevada resolução e diagnóstico em deteção de infraestruturas, estudo de edifícios, pavimentos, pontes, túneis, geotecnia e aterros [32].…”

ResumoA caracterização do Mosteiro da Batalha incluiu o método de prospeção geofísica de radar de penetração no solo (GPR). Este método, não destrutivo e indireto, permite obter imagens 2D/3D de elevada resolução das estruturas investigadas. Devido à natureza do estudo, foram utilizadas grelhas de medida e parâmetros de aquisição adequados, elevada precisão da localização dos pontos de leitura e processamento de dados adaptado. O GPR clarificou questões relacionadas com a construção e o estado de conservação do Mosteiro. São apresentados resultados da investigação do terreno sob o Mosteiro, localizando infraestruturas recentes e antigas, fundações de colunas e estruturas de interesse histórico-arqueológico. A caracterização de elementos construtivos justificou a utilização do GPR na superfície das paredes do claustro de D. João I, permitindo propor uma estrutura interna do aparelho construtivo das paredes. O GPR provou ser eficaz e expedito e permitiu obter informação indispensável para contribuir para a preservação, recuperação e reabilitação do monumento. AbstractThe characterization of the Monastery of Batalha included the use of the geophysical method of ground-penetrating radar (GPR), a non-destructive and indirect method that provides highresolution 2D/3D images of the structures to investigate. Owing to the nature and aims of the survey, appropriate measurement grids, acquisition parameters and adapted data processing techniques were used. The GPR survey provided important information about the Monastery foundations, construction and conservation. GPR high-resolution images allowed to locate recent and ancient infrastructures, columns foundations and structures of historical-archaeological interest. The characterization of the Monastery walls was also carried out using GPR on the surface of walls of the Cloister of D. João I and of the Church. These results contribute for the proposal of an inner structure model of the walls. GPR proved to be an efficient and expeditious method that allowed obtaining information to be used in the preservation, recovery and rehabilitation of the Monument.
