Paper Title
Applying Laser Scanning and Digital Photogrammetry for Developing an Archaeological Model Structure for Old Castle in Germany

Abstract
The evaluation and documentation of the preservation of the archaeological structure is an important step in any management plan. Still, using this with a safe methodology and low cost has always been a challenge. It is also a time-consuming process. There is therefore a need for an inexpensive and efficient methodology to document the state of a structure. In this article, laser scanners (LS) and digital photogrammetry (DP) are used for one of the most important structures in Germany, the Old Castle. The place is well known for its unique pieces. But, due to the environmental conditions and the lack of ongoing monitoring, maintenance and repair plans, the lock is seriously at risk of deterioration. DP is a generally accepted method for collecting 3D images of the surroundings. For this cause, this image-based method is often used to create high-quality 3D models of cultural heritage and historical buildings for presentation purposes and for documentation. Terrestrial LS are also used, which measure 3D surface coordinates directly based on the execution time of the reflected laser pulse. These systems are characterized by high data acquisition rates, high spatial data density and good accuracy. Regardless of the possibilities of each approach, this paper expects the greatest benefit from combining data from both digital cameras and terrestrial LS. In this study, we examine the use, apps, and advantages of this technique with a view to creating some realistic 3D texture models of the old castle. The model is applied as a diagnostic tool for castle conservation and monitors the average of future developments.
