Thermal imaging-based mortise and tenon joint internal dimension detection system and method

Abstract

The invention relates to a thermal imaging-based mortise and tenon joint internal dimension detection system, which is used for detecting the internal dimension of a beam column mortise and tenon joint, and comprises a thermal radiation heating assembly, a thermal imager and an image processing module, wherein the thermal radiation heating assembly is arranged around the beam column mortise and tenon joint and is used for generating heat flow to the beam column mortise and tenon joint, the thermal imager directly faces the beam column mortise and tenon joint and is used for conducting infrared detection on the beam column mortise and tenon joint to obtain a thermal imaging picture and sending the thermal imaging picture to the image processing module, and the image processing module conducts image processing on the thermal imaging picture, the position of the connection interface of the beam column mortise and tenon joint is determined according to the temperature displayed by the thermal imaging picture, detection of the internal size of the mortise and tenon joint is achieved, and compared with the prior art, the method has the advantages of being free of damage to the structure, easy and convenient to operate, reasonable, reliable and the like.

Description

technical field [0001] The invention relates to the field of civil construction and structural engineering, in particular to a system and method for detecting internal dimensions of mortise and tenon joints based on thermal imaging. Background technique [0002] Wooden structure is one of the main traditional building structures in my country. There are still many traditional wooden structure buildings that have survived to this day, and most of them are historically protected buildings. As time goes by, traditional wooden structures will experience a series of problems such as structural performance degradation, so it is necessary to strengthen the detection, identification and reinforcement of traditional wooden structures. [0003] Traditional wooden structures are generally connected by wooden beams and wooden columns through mortise and tenon joints. Many studies have shown that mortise and tenon joints are the key parts of wood structures. On the one hand, mortise and...

Problems solved by technology

However, in the actual detection process, due to the concealment of the mortise and tenon joints, its internal dimensions are difficult to obtain, so it is often ignored
