Natural disaster early warning system and method

The invention discloses a natural disaster early warning system. The natural disaster early warning system comprises an information acquisition unit, an image processing unit, a prediction model establishing unit, a disaster prediction unit and an early warning unit. According to the invention, a machine learning method is adopted to train disaster sample data in a sample data set formed by quantizing scene image information shot by a camera and natural state information detected by a sensor; detection is performed according to the evaluation indexes to obtain an optimal disaster prediction model; disaster prediction can be carried out on a scene transmitted by the information acquisition unit in real time in the disaster prediction model; a distributed data processing system constructed by a plurality of servers and computing hosts is adopted in the prediction model establishing unit to train the sample data, and the distributed system performs parallel training on the sample data, sothat the efficiency is e
