Review of Surveying Devices for Structural Health Monitoring of Cultural Heritage Buildings

Cultural heritage is the evidence of the past. Nowadays monumental objects create the important part of the cultural heritage, so it is essential to document this type of objects and perform structural health monitoring analysis for preservation. Currently, the digital architectural documentation is recorded as vector drawings, digital object models, 3D models or orthoimages, which are the obligatory form of the inventory of historical objects [1]. In order to generate this type of high resolution and high quality documentation, different sensors as well as appropriate methods are used. The aim of this paper is to present both the conception of the novel surveying device (based on RGB camera, Terrestrial Laser Scanning - TLS with electromagnetic sensor) and methodology of data processing. This paper will review existing state of the art sensors and discuss their advantages and disadvantages as well as the further improvement of such sensors. Additionally, the conception of the new architectural documentation will be described.
