Ancient building safety determination method and device, electronic equipment and storage medium

The invention relates to an ancient building safety determination method and device, electronic equipment and a storage medium. The historic building safety determination method comprises the following steps: obtaining a vibration signal of a historic building as an original signal; performing empirical mode decomposition on the original signal to obtain a plurality of intrinsic mode components; reconstructing the original signal by using the obtained intrinsic mode component; obtaining a noise-removed reconstructed signal by using the reconstructed original signal and the intrinsic mode component; obtaining a correlation coefficient distribution diagram by calculating a correlation coefficient between the reconstructed signal after noise removal and the original signal; determining an intrinsic mode component index according to the correlation coefficient distribution diagram; identifying and judging false intrinsic mode components according to an energy conservation principle by utilizing intrinsic mode com
