The invention belongs to the technical field of intelligent detection and machine vision, and discloses a visual waste classification aid system, method and device based on artificial intelligence. The method includes the steps that when a pedestrian is close to the artificial intelligence visual waste classification aid system, a camera detects the pedestrian, and the system enters a waste recognition mode; the camera collects images of the pedestrian from far to near; and waste in the hand of the pedestrian is recognized through a recognition algorithm, a recognition result is displayed on ascreen, classification of the waste is achieved, and the pedestrian is instructed through screen animations to complete waste putting. Different waste can be intelligently recognized through shapes,texture, the reflectional degree and colors, and after successful recognition, the waste is automatically classified as hazardous waste, other waste, kitchen waste and recyclable matter; and then themasses are prompted to automatically put the waste, in addition, due to application of a face recognition technology, violation operation of residents can be managed and controlled, and the waste classification efficiency and quality are improved.
