Therefore, there is a great need for real-time health monitoring and assessment of structures to improve their safety performance. If these damages and defects are not foreseen and monitored in a timely manner, they can not only cause significant property damage but also pose a great threat to personal safety. These potential damages and defects will make a structure much less stable and safe, thus increasing the likelihood of catastrophic accidents. Long-term exposure to complex working conditions will inevitably result in varying degrees of damage and defects in these structures.
Especially since the 1990s, there has been an increasing emphasis on monitoring the quality and longevity of modern structures, due to the implementation of engineering projects such as large concrete buildings, large steel structures, and geotechnical structures. The rapid development of various industries in today’s society has caused the composition, form, and function of many structures to become increasingly complex. The conclusions show that this new integrated sensing technology can effectively utilize the advantages of both fields. This paper demonstrates the feasibility and application potential of this integration by citing numerous examples. In addition, the main contribution of this paper is that the integration of fiber optic sensing technology and vision sensing technology is discussed. It introduces the advantages, limitations, and future directions of these two sensing technologies. It provides the reader with a broad review of the literature.
This paper focuses on the basic principles, recent advances, and current status of applications of these two sensing technologies. In recent years, the development of fiber optic sensing technology and vision sensing technology has led to further advances in structural health monitoring.
As a structural asset management approach, it can provide a cost-effective measure and has been used successfully in a variety of structures. Structural health monitoring is currently a crucial measure for the analysis of structural safety.
