Moisture detection in heritage buildings by 3D laser scanning

摘要: Moisture is one of the main factors in deterioration heritage buildings, causing mould, unwanted parasites, and decanting salts, which, turn, aggravate such degradation. The existence moisture not only affects building aesthetically, but also evidence bad conservation conditions. It thus extremely important to verify assess extent moisture, even though it may be confirmed by mere visual inspection. This article describes an innovative straightforward procedure automatically show where appears, as well affected area. based on use 3D laser scanner surveying data for documentation purposes historic buildings. Data are processed off-line order analyse reflectivity level. method intrusive, allows large areas covered a short time, does interact with materials, which makes optimal application these special Hence, professionals conservati...
