The invention provides a method, device and system for detecting objects entering and exiting from an elevator cage, and belongs to the technical field of construction elevators. The elevator cage object entering and exiting detection method comprises the steps that when an object enters an elevator cage, correlation condition information of a safety grating on the elevator cage is obtained; based on the correlation condition information of the safety grating, extracting shielding features; based on the shielding features, a preset in-out object detection model is adopted for detection, and a detection result is obtained; wherein the safety optical grating comprises a plurality of groups of transmitting optical gratings and receiving optical gratings, and the plurality of groups of transmitting optical gratings and receiving optical gratings are arranged on the two sides of a lift cage door at intervals, so that the correlation range of the safety optical grating covers an inlet and an outlet of the lift cage. Object types can be automatically and accurately detected according to the infrared correlation shielding condition of the safety grating, and therefore elevator owners and managers can manage and control elevator riding to the maximum extent.
