Method and device for rapidly and intelligently detecting physical and chemical indexes of hazardous wastes, terminal and medium

The invention is suitable for the technical field of hazardous waste monitoring, and provides a hazardous waste physical and chemical index rapid intelligent detection method and device, a terminal and a medium, and the method comprises the steps: obtaining different types of hazardous waste sample pictures, and constructing a sample picture data set based on the same type of hazardous waste samples; labels of the sample picture data set comprise physicochemical property indexes of different types of hazardous wastes; extracting image features of the sample picture data set based on a neural network to obtain image feature vectors; the image feature vector and the physicochemical property index have an incidence relation; carrying out feature fusion on the image feature vectors and the physicochemical property indexes based on the incidence relation by adopting canonical correlation analysis in multi-scale feature fusion to obtain fused image features; inputting the fused image features into a time sequence p
