Abstract: An information processing method and device, and a storage medium are provided. The method includes: obtaining first input information, the first input information including at least an image containing a target object (101); obtaining, based on the first input information, captured images of the target object that are captured by an image acquisition device within a time period from N seconds before a target time point till N seconds after the target time point, the target time point being the time point when the image acquisition device captures the target object (102); determining companions of the target object from the captured images (103); and acquiring a companion identifying result by analyzing the one or more companions based on aggregated profile data, each person in the aggregated profile data corresponding to a unique profile (104).

Abstract: A bridge intelligent cable system with a built-in fiber grating sensor is provided, which is applied in a cable bearing structure such as a cable-stayed bridge, a suspension bridge, and an arch bridge. The system includes an anchor cup, a wire dividing plate, a connecting cylinder, a fiber grating sensor, and a cable body, in which the fiber grating sensor includes a fiber grating strain sensor and a fiber grating temperature sensor, tail fibers of the fiber grating strain sensor and the fiber grating temperature sensor are led out, the packaged fiber grating strain sensor is fixedly connected to an outer-layer steel wire of the connecting cylinder, the packaged fiber grating temperature sensor is suspended on the steel wire of the connecting cylinder, holes are punched in the wire dividing plate, and a preserved steel pipe is buried in advance in the connecting cylinder and the anchor cup.
