Abstract

Sustav za multispektralno snimanje jedan je od brojnih načina digitalizacije kulturne
baštine. Njime se mogu dohvatiti informacije koje su slabo vidljive ili nevidljive
ljudskom oku što ga čini idealnim alatom za proučavanje povijesnih dokumenata koji
često na sebi nose veliku štetu. To je hardverski i softverski sustav koji kombinira podatke
dobivene prilikom snimanja infracrvenom, ultraljubičastom i vidljivom svjetlosti. Tako
se snimanje uzoraka vrši pomoću multispektralne kamere s filterima koji propuštaju samo
određeno, vrlo usko područje valnih duljina svjetlosti u kameru te softwarea na računalu
na kojem se prikazuje dobivena fotografija. Daljnjom obradom zabilježenih fotografija
naglašavaju se elementi koji se proučavaju, dok se ostatak fotografije izolira. Ovaj rad
napravljen je u suradnji s Hrvatskim državnim arhivom u Zagrebu te sažima postupak
obrade elementa koji su uključivali rukopis koji datira iz 17. stoljeća. Rukopis je snimljen
s ukupno 36 optičkih filtera. Ovim radom se pokušava objasniti važnost multispektralnog
snimanja koje može donijeti i superiornije rezultate od tradicionalnih, analognih
postupaka digitalizacije kulturne baštine. Također, rad pokazuje veliku ulogu
multispektralnog snimanja u očuvanju originala s obzirom na to da ovim načinom ne
činimo nikakvu štetu originalnim uzorcima snimanjem te se samim time očuvanost
originala ne riskira kao kod analognih metoda digitalizacije. Iz tog razloga možemo reći
da je multispektralno snimanje nedestruktivna, neinvazivna i beskontaktna metoda, a
njime se može postići daljnje razumijevanje povijesnih građa.

Abstract (english)

The system for multispectral imaging is one of the many ways of digitizing cultural
heritage. It can retrieve information that is barely visible or invisible to the human eye
which makes it an ideal tool for studying historical documents that often carry great
damage. It is a hardware and software system that combines data obtained during infrared,
ultraviolet and visible light imaging. Thus, the imaging of samples is done using a
multispectral camera with filters that allow only a certain, very narrow range of
wavelengths of light into the camera and software on a computer that displays the
obtained photo. Further processing of the recorded photos emphasizes the elements under
study while isolating the rest of the photo. This paper was made in collaboration with the
Croatian State Archives in Zagreb and summarizes the process of processing the element
that included a manuscript dating from the 17th century. The manuscript was recorded
with a total of 36 optical filters. This thesis tries to explain the importance of multispectral
imaging which can bring superior results than traditional, analog methods of digitizing
cultural heritage. Also, the thesis shows the great role of multispectral imaging in the
preservation of the original, considering that in this way we do not cause any damage to
the original samples by recording and thus the preservation of the original is not at risk
as with analog digitization methods. For this reason, we can say that multispectral
imaging is a non-destructive, non-invasive and non-contact method and it can be used to
achieve a further understanding of historical materials.
