The invention relates to a method and system for identifying a pressing plate state of a power screen cabinet based on AR glasses. The method comprises the following steps of receiving a pressing plate picture taken by AR glasses in a power screen cabinet on the spot; segmenting each individual platen picture in the platen picture in the power screen cabinet by an OpenCV color recognition method;through the trained VGG model for each individual pressure plate picture recognition, and identifying each individual pressure plate in the power screen cabinet for the status of throwing or retreating. The invention adopts the OpenCV color recognition algorithm to divide the edge of the platen, which can improve the recognition accuracy and greatly shorten the recognition time. The VGG model is used as the recognition model of platen state, which can quickly and effectively complete the recognition task under different angles and different illumination conditions. At the same time, by combining with AR glasses for image acquisition, the method and the system can not only liberate hands and standardize the operation, but also superimpose the platen state on the real image to improve the visual development ability.
