A method for constructing a digital twin monitoring model for slopes based on a proxy model includes S-S. S, a slope geometric model consisting of M triangular facets is constructed. S, a first training dataset is constructed for pretraining a pre-proxy model by using the slope geometric model. S, monitoring data of the M triangular facets are collected in real-time to construct a second training dataset for training the proxy model. S, a warning cloud map of the slopes is generated. The method uses the slope geometric model to obtain simulation data under multiple physical field conditions. It constructs training dataset of pretraining pre-proxy model based on the simulation data, which greatly reduces training samples. Moreover, the multiple base learners in the proxy model can reduce the computational bias of a single time-series analysis model, improving the prediction accuracy of the proxy model.

A three-dimensional displacement compensation method is provided. The method includes an obtaining step, a transforming step, a first determining step, a first calculating step and a compensating step. The obtaining step includes obtaining a current image of a measured element captured by a microscopic thermoreflectance thermography device. The transforming step includes two sub-steps. One sub-step uses Fourier transform to calculate a reference image to obtain a first result, and the other sub-step uses Fourier transform to calculate the current image to obtain a second result. The first determining step includes determining a peak point coordinate and a fitting diameter of a point spread function of an optical system of the device. The first calculating step includes calculating a three-dimensional displacement of the position to be compensated relative to the reference position. The compensating step compensates the position to be compensated.
