The invention provides an open set identification method and device based on an isolated forest, equipment and a storage medium, and belongs to the technical field of computer vision. The open set recognition method comprises the following steps: constructing an open set recognition model based on an isolated forest, wherein the open set recognition model comprises an image recognition model and an isolated forest model; inputting a to-be-recognized image into the image recognition model to obtain a category vector and a low-dimensional representation of the image; inputting the low-dimensional representation of the image into an isolated forest model to obtain a decision path length; and removing abnormal images by using the decision path length, and judging the category of the image by using the category vector of the image. According to the open set recognition algorithm provided by the invention, an image recognition model and an isolated forest model are combined, images of unknown categories can be elim
