Monitoring gradual decay with 3D scans

Creeping decay and weathering can be monitored quickly and cost-effectively using modern 3D scans in order to initiate protective measures at the right time.

Monuments and outdoor objects in particular are more affected by wind and weather than you might think. As the erosion processes are usually gradual, the increasing damage is usually noticed too late. For example, a kind of blind spot develops when people walk past the objects every day. As the changes accumulate subtly over time.

When it is then necessary to initiate protective measures, the search for old photos, pictures and drawings begins in order to evaluate the original condition. Unfortunately, these sources are usually only fragmentary, outdated or of poor quality (old slide images, publication images in which views of the backs are missing, for example….)

With the help of 3D scans, the actual condition at the time of scanning can be fully recorded across the entire object. The data is available quickly and easily and can be shared with the relevant conservators. They depict the ENTIRE object and can be used to create complete replicas in an emergency.

The example shown here is a simple wooden object, a seat cut from a tree trunk. It is not a monument in the true sense of the word, but it shows how quickly decay processes can take place.

The wooden seat was captured by me in 2020 using 3D photogrammetry. This was done about 2 years after it was carved.

The photographs show the condition in June 2025. The bark has disappeared over a large area. Rain, sun and snow have attacked the surface and pests have infested the wood. The seat is damaged and the entire object is about to fall over.

Within 5 years, the wooden object is on the verge of complete decay. Processes like these also take place in stone monuments, such as sculptures and façade decorations. However, the time periods are longer due to the material and the process is gradual.

Due to the large number of outdoor monuments, monitoring is difficult, but can be facilitated by a digital comparison collection. In addition, the 3D scans can also achieve synergy effects for other purposes.

They facilitate publication, offer quick comparison possibilities as a comprehensive collection and can be made accessible to the public quickly and securely for the objects. Decentralized storage also preserves the digital twin of the object in the event of extreme disasters (landslides, war, vandalism, floods, etc.).
