The invention discloses an image data target identification method based on a data graph framework, an information graph framework and an knowledge graph framework and belongs to the crossing field ofdistributed calculation and a software engineering technology. According to the method, the data graph framework, the information graph framework and the knowledge graph framework are mainly introduced to conduct knowledge reasoning on unidentified images, and therefore entity targets in pictures or images photographed by a camera are automatically and intelligently identified. The method includes the specific implementation steps that a path capable of accessing the history of unidentified targets is found in data graphs or information graphs or knowledge graphs by analyzing identified targets, entities on the path are traversed, feature matching is conducted at the same time, and finally an identification result which has the highest matching degree with the unidentified targets is found.
