Deformation measurement plays a crucial role in large-scale structures, experimental mechanics, and structural health monitoring. However, the current measurement methods do not meet the requirements of precise, efficient, and cost-effective measurements for such structures on a large scale with high precision. Therefore, there is an urgent need for new measurement methods and technologies. In recent years, videometrics methods, which utilize cameras as sensors, have gained popularity due to their non-contact nature, high accuracy, and low cost. This paper reviews both single-camera and multi-camera measurement systems based on the camera network measurement method and system developed by our team. It discusses key algorithms used in multi-camera systems, including image acquisition, camera calibration, feature extraction and tracking, and deformation calculation. Additionally, the paper explores the applications of videometrics technology in long-term monitoring and rapid detection, as well as the main factors that influence system stability. Finally, it summarizes the achievements and challenges of measurement methods and technologies for static and dynamic deformation of large-scale engineering structures, providing an outlook on future development trends.
