Determination of wood moisture content with terrestrial laser scanner
Highlights The capacity of the laser scanner for detecting moisture levels is tested. It was found, on wood samples, a relation between the intensity and the moisture. Further experiments will be focused on testing the methodology in real conditions. A xylohygrometer and physical tests were used for contrasting the data.
Abstract The aim of this work is to evaluate the ability of terrestrial laser scanning technology to detect the moisture content in timber structures. For this purpose, an extensive experimental campaign was carried out under laboratory conditions. During the campaign, several wood samples were digitised using the Faro Focus 120 phase-shift laser scanner for which a radiometric calibration model is available. The digital level (intensity) of each 3D point cloud was then converted into reflectance values (0–1). These reflectance values were related to the moisture content of samples which was obtained using the oven-drying method and the resistive xylohygrometer device. Finally, a simple methodology based on experimental analytical equations was proposed. The results show that the laser scanner could be a potential non-destructive tool for the diagnosis of wooden construction systems, as it is not only able to detect deformations but also to infer the moisture content of specific areas in wood elements.
