Laser Scanner and Total Station in the Árpád-age Church of Tarnaszentmária

A group of students and teachers from the Mikoviny Sámuel technical college surveyed one of the oldest churches of Hungary on 27 February, 2017. The church has been preserved almost intact in its original style and form.

For the surveying we used three types of technologies and instruments: terrestrial photogrammetry, laser scanner and total station. For 3D modeling we used Sony and Nikon cameras for taking images. Scanning was made by a LeicaC10 and a Faro instrument. For the latter I would like to express my sincere gratitude for Attila Weisz, a correspondent student for lending one from the Salisbury Ltd. We also used a new Geomax Zipp20 R2 total station. The possibilities of distance measurement without prism and that of the offset measurement of marks were beneficial, too.

We scanned the inside and outside of the church with high accuracy including the crypt, which can be found under the apses of the church. There is a narrow flight of stairs leading down to the wide-stone crypt. In the case of the Leica instrument for fitting we used the manufacturer’s marks outside the building, while inside printed paper-marks were on the walls.

In the case of the Faro instrument, fitting spheres were used for point cloud fitting. We defined the coordinates of every fitting point in the local and national co-ordinate systems so we will be able to give the results of all types of measurements in a unified co-ordinate system.

The different surveying technologies served different purposes. One of them was to inspect the relationship between the proportions of the 11-12 century parts of the church and the royal Hungarian linear unit system. With the help of the total station measurement even the precise assessment of the layout of the church was possible to carry out together with the definition of point cloud fitting in a unified co-ordinate system. This method was already used in four other Árpád-age churches (Kallósd, Bagodvitenyéd, Ják, Pápoc). The preliminary examinations are promising; the ultimate results will probably confirm our concepts.

We are going to assess the results and the reference examinations in a SSA dissertation.

Point Cloud Processing

The Hungarian Society of Surveying, Mapping and Remote Sensing, Department of Photogrammetry and Remote Sensing of the University of Óbuda and Mikoviny Samuel College had a joint event where valuable presentations were read on “point cloud processing” topic. The presentations touched the themes of terrestrial and aerial laser survey technologies, application possibilities. We were acquainted with the data processing and the hardware and software visualisation solutions via spectacular slides. The informal form and the appropriate time frame allowed to the speakers to present their research, their results in a detailed report. Onthe other hand the audience had interesting questions and propositions as well.

Dual Workshop: Corporate Experience on the Agenda

Corporate experience was shared by the participants of the dual workshop on Thursday morning at the Alba Regia Technical Faculty of Óbuda University, where dual training was launched two years ago with 19 students of engineering information. This March there are almost 70 students at the faculty in Székesfehérvár on one of the five dual BSc courses (land surveying and land management engineer, mechanical engineer, electrical engineer, informatics engineer, technical manager). In the  2017/2018 session  160 practical training places will be available for the entering students at the dual partner companies.

Monika Pogátsnik, head of the Dean Office was talking about the time management of 2016/2017, the preparation of practical training timetables, and the adjustment of the academic schemes to the dual training curriculum, the enrolment promoting activities and making dual contracts for 2017/2018. In addition she provided practical information for the participants of the workshop in connection with the preparation of the contracts and creating WebPages.

Richárd Veres, HR and Public Relations manager described the enrolment promoting marketing activity of the 2017/2018 dual session in the organization of the self-government of Székesfehérvár. He reminded the participants of the Dual Information Day (27/04/2017 in the assembly room of the City Hall). It will be the next forum where high-school nominees and dual companies can meet.

In general, dual training companies reported that the dropout of dual training students is minimal; they were satisfied with dual training. The new partner companies from September, 2017 are going to prepare for the reception of the students. The participants agreed on the importance of finding suitable mentors in the dual program.
The representatives of the university gave the possibility of a corporate mentor program. The workshop was accomplished with the drafting of tasks.

„Modern Technologies in the third Millennium”, a conference in Nagyvárad

The Alba Regia Technical Faculty of Óbuda University represented itself at the international conference: Modern Technologies in the third Millennium at Nagyvárad State University on 23-24 March, 2017.
The Faculties of Civil Engineering, Land Surveying and Architecture were the host faculties. We have had years of professional and personal contact with our colleagues at the university, namely with István Suba and Norbert Suba, who regularly take part at our annual GISOpen conference. Two of our teachers gave lectures at the conference. Lóránt  Földváry’s lecture was about „Accuracy Assessment of UAV for Surveying”; János Katona’s lecture dealt with „Statistical Values for Assuring Productivity in Land Consolidation”.

The venue of the conference was in the recently refurbished castle providing a unique atmosphere to the lectures on modern technologies. Despite the shortage of time and the tense space of the event our hosts were able to take us for a sightseeing tour and to the site of a current engineering geodesy works . There has been a land-slide on the so called Kálvária-hill, which damaged the public utilities and moved away the pieces of a building tens of meters from their original place. It happened in November, last year. The motion of the earth has been regulary measured since then by our colleagues at Nagyvárad State University. At the closing dinner of the conference we planned the possibilities of our future co-operation in the form of the Erasmus program and international conferences.

Sharing our Knowledge at International Level

Two of our colleagues from the Alba Regia Technical Faculty of Óbuda University (Verőné Dr. Wojtaszek Malgorzata and Petőné Dr. Csuka Ildikó) were able to visit the Technische Hochschule Wildau in Germany as members of the delegation from the different faculties of Óbuda University (AMK, BGK, KVK) after being chosen for the project.

The Rector of TH-Wildau, Prof. László Ungvári gave us a hearty welcome together with all of the lecturers and associates of the institute in Wildau and arrenged an excellent program for the Hungarian colleagues. We were given the possibility to take part in English-speaking lectures and seminars on BSc and MSc level and to have an insight into the incentive system and quality management of the German institute with the help of Prof. Ulrike Tippe Vice-Educational Rector. We even visited the university library of Wildau, which won the title „Best library of 2012”. Prof. László Ungvári took us to the Hungarian Embassy in Berlin where we were greeted by Eszter Pászti-Márkus, Academic and Research Attaché.

In Wildau we had a look at the WinLab laboratory, where the students, the teachers and the researchers can experiment with the help of 3D printers and the activity of the surgical instrument laboratory was also disclosed for us. Testing the airplane simulator was an exceptional experience for us.

The structure of the BSc and MSc courses (Martin Bradbeer and Prof. Rainer Stollhoff) was shown to us as part of the sharing information on the educational process. We agreed on the strengthening of our relationship in the future both in the field of research and education. Our mutual aims are:

  • facilitating student and lecturer mobility,
  • joint training or dual degree ,
  • joint researching activities in the futu

„Basically I was curious about the operation of the higher educational institute and the experiences of our colleagues abroad. They were most helpful and cooperative; we had a lot of open and friendly discussions about situations which are sometimes the same, sometimes different from our experiences.”

The next phase will be the visitation of TH-Wildau’s Rector, Prof. László Ungvári  in May!
