A PM2.5 measurement method based on image features and integrated neural network

The invention relates to a soft sensing method for PM2.5 of air fine particles based on image features and an integrated neural network, which belongs to the field of both environmental engineering and detection technology. An atmospheric environmental system has many variables, nonlinear and complicated internal mechanism. Compared with single neural network, an ensemble neural network has betterability to deal with highly nonlinear and seriously uncertain system, and the real-time and high efficiency of PM2.5 prediction can be improved effectively by using image features as input variables.The invention aims at the problem that PM2.5 is difficult to predict with high precision and real-time.
