Methods for detecting deterioration of wooden components in ancient buildings

Abstract

This invention discloses a method for detecting the deterioration of ancient architectural wooden components, belonging to the field of wood testing technology. The method includes: using a pin probe to detect selected test points on various ancient architectural wooden component samples, obtaining the pin penetration depth at each test point; using an infrared spectroscopy device to collect the spectral data of wood powder on the probe hole walls at each test point, obtaining infrared spectral data for each test point; constructing a K-means clustering model based on the pin penetration depth and infrared spectral data of each test point; acquiring the pin penetration depth and infrared spectral data of the ancient architectural wooden component to be tested, and inputting them into the constructed K-means clustering model to obtain the deterioration level of the ancient architectural wooden component to be tested. This invention has simple steps, strong operability, and accurate detection results, meeting the requirements of accuracy and non-destructive testing for the deterioration of ancient architectural wooden components, and can be widely used in the field of ancient architectural wooden component deterioration testing.
