Coal mine safety estimation analysis method and system based on three-dimensional face image recognition

The invention provides a coal mine safety estimation analysis method and system based on three-dimensional face image recognition, and relates to the technical field of coal mine safety estimation analysis, and the method comprises the steps: obtaining coal mine safety historical data and underground coal mine face image data, carrying out the emotion recognition of the recognized facial expression information through an emotion analysis model, and obtaining an emotion recognition result; the emotional state of the worker is obtained; extracting voice features by adopting an acoustic feature extraction method to obtain a first feature vector; monitoring the posture motion data by using a motion sensor to obtain a second feature vector; and constructing a time sequence data set, taking a time sequence data sample as an input data source to train the coal mine safety prediction model, and estimating the change trend of the coal mine safety state in the future. The beneficial effects of the invention are that th
