ABSTRACT: 
The goal of RECORDS (Reaching Recording Data Technologies) is the digital capturing of buildings and cultural heritage objects in 
hard-to-reach areas and the combination of data. It is achieved by using a modified crane from film industry, which is able to carry 
different measuring systems. The low-vibration measurement should be guaranteed by a gyroscopic controlled advice that has been , 
developed for the project. The data were achieved by using digital photography, UV-fluorescence photography, infrared 
reflectography, infrared thermography and shearography. Also a terrestrial 3D laser scanner and a light stripe topography scanner 
have been used The combination of the recorded data should ensure a complementary analysis of monuments and buildings 
1. INTENTION 
1.1 Fundamental ideas 
In context of the applied scientific research at the University of 
Bamberg RECORDS (Reaching Recording Data Technologies) 
has been invented. 
The standard requirement of a reliable duty in the field of 
protection and renovation and also in the field of research in 
cultural heritage preservation is documentation and monitoring. 
Thereby exactly measuring and imaging of building 
components of any kind is a central topic. However at this point 
problems appear often. Nevertheless the measurement is not the 
primarily problem, external factors exacerbate the practice 
much more. 
Tall heights and hard reachability as a result of this prejudice 
the usage of these techniques. In practice most frequent 
requested working heights are between 15 and 20 meters. 
Furthermore there are demands, that the works should not 
compromise the usage and should be accomplished quick, 
reliable, affordable, nondestructive and contactless. 
1.2 Basics and project development 
The experiences, which were made in former research projects, 
whose goal were primarily the photographic documentation of 
mural painting and stained glass (VITRA) and the usage of a 
terrestrial laser scanner (RRS), leaded to the research project 
RECORDS, which was started in 2012. The predecessor 
projects promoted an advancement respectively an optimization 
of a modular crane system with a vibration stabilizing platform, 
which could carry different, valuable measuring instruments, 
additional to the photography. 
It will be used, next to an usual remotely controlled camera for 
high-resolution image capture, an ultraviolet camera and 
infrared cameras for multispectral image capturing with this

crane. For 3D-scanning a terrestrial laser scanner and a light 
stripe topography scanner are used. Inside this project it will be 
tested how far the shearography (laser-speckle-technique) can 
be used sensible. 
1.3 Realisation 
RECORDS is promoted by the “Bayerische 
Forschungsstiftung” (BFS). Four more partners are involved 
under the direction of the University of Bamberg. These project 
participants are small and medium- sized businesses, which 
accomplish advancements and optimizations at their current 
department. 
2. SYSTEMTECHNOLOGY 
2.1 Crane 
The linchpin is the advancement of a film crane (GF16) of the 
Munich company “Grip Factory Munich GmbH". The crane is 
made of modular parts and is useable for the devices to a height 
up to 16 meters (pic.1). Crucial for the use of this crane is the 
high stability despite the high flexibility, likewise the 
ruggedness, the good transport property and the easy and quick 
assembly. It works entirely mechanic and requires just a team 
of two or three people locally. An additional highlight is the 
optional usage as crane for passengers up to a working height of 
10 meters, which constitutes a further enrichment within the 
scope of documentation and study of cultural heritage. To use 
the highly vibration sensitive devices at the crane, it was 
necessary to develop a head, stabilized by a gyroscope (pic.3), 
which is equipped with an appropriate platform to use the 
different devices and steer them from the ground.
