Abstract
The invention relates to the technical field of intelligent construction and maintenance, and relates to a non-contact visual monitoring system and method for a flexible protective structure against rockfall disasters; it comprises a hardware system and a data analysis system, and the hardware system uses a multipoint distributed high-resolution high-speed camera to capture dynamic image sequences of a protective structure under the rockfall impact in a non-contact mode; the data analysis system comprises an impact deformation state full-field tracking module and a multipoint impact large deformation extraction module, and the impact deformation state full-field tracking module captures spatio-temporal changes of impact deformation of the protective system by adopting a full-field optical flow method, constructs a two-dimensional velocity amplitude distribution diagram and performs full-field spatio-temporal tracking of large deformation of the system.
