Abstract: The embodiments of the present invention disclose a weather recognition method and device based on image information detection, which includes: obtaining an image to be detected; extracting multiple first image features of the image to be detected with respect to each preset type of weather according to a number of first preset algorithms preset correspondingly for different preset types of weather; inputting the extracted multiple first image features to a preset multi-kernel classifier, the multi-kernel classifier performing classification according to the inputted image features to identify the weather in which the image to be detected was taken; wherein the multi-kernel classifier is a classifier for the preset types of weather realized by: selecting a first preset number of image samples for the different preset types of weather in which the image was taken respectively; and for the image samples of each preset type of weather respectively, extracting the first image features of each image sample accordi
