Advances in Research of Computer Vision Structural Health Monitoring and Its Application Prospect in Large Amusement Rides

In production and life, the structural safety of equipment and facilities is very important to ensure the national economic operation and people's daily life. Structural health monitoring can effectively improve the safety and stability of equipment and facilities. Structural health monitoring technology based on computer vision measurement has attracted more and more attention with the development of computer vision measurement technology and the improvement of hardware levels. Computer vision measurement has been widely used in the monitoring fields of surface defects, spatial coordinates, displacement and cable tension of structures. However, it is seldom used in structural health monitoring of large amusement rides. In this paper, the overview of computer vision is introduced, the research progresses are summarized and the application prospects are carried out. Firstly, the development history of computer vision is sorted out in chronological order. Then, the hardware and software components of computer vision measurement are summarized, the main features of each component are pointed out. It mainly introduces the application status of computer vision measurement technology in various fields, compares it with traditional measurement methods, and points out the characteristics and shortcomings of various methods. Finally, the application prospect of computer vision measurement technology in structural health monitoring of large amusement rides is put forward. The main research direction and key tasks of computer vision measurement technology in structural health monitoring of large amusement rides are pointed out. © 2023 Editorial Office of Chinese Journal of Mechanical Engineering.
