Image annotation method, system and equipment based on target detection and medium

The invention provides an image annotation method, system and device based on target detection and a medium, and the method comprises the steps: obtaining a to-be-annotated image, carrying out the first target detection of the to-be-annotated image, and obtaining a first recognition result; according to bounding box information in the first identification result, extracting a sub-image corresponding to a target object in the to-be-labeled image to obtain a sub-image sequence; performing second target detection on the sub-graphs in the sub-graph sequence to obtain a second recognition result; and comparing bounding box information of the target objects of the same category in the first recognition result and the second recognition result, and determining a target bounding box of the corresponding target object in the to-be-labeled image according to a comparison result so as to label the corresponding target object in the to-be-labeled image. According to the invention, the efficiency and precision of automati
