The present disclosure provides a pedestrian re-identification method and apparatus. The pedestrian re-identification apparatus detects a pedestrian to be identified in a specified video frame, and within a specified time period before the capture time of the specified video frame, extracts all pedestrians appearing in the captured video frame and taking them to be historical pedestrians; calculating the feature distances between the pedestrian to be identified and the historical pedestrians; in order of feature distance, from small to large, extracting historical pedestrian identifications corresponding to a predetermined number of feature distances, and clustering the extracted historical pedestrian identifications so as to re-identify the pedestrians to be identified. The present disclosure effectively suppresses external noise interference and improves the success rate of pedestrian re-identification.

The invention discloses an augmented reality method and device, and relates to the field of computer technology. A specific implementation of the method includes: acquiring video information of a target, and acquiring real image information and real sound information of the target from the same; using the real image information to determine at least one image-based target state data, and using the real sound information to determine at least one sound-based target state data; fusing the image-based and sound-based target state data of the same type to obtain a target portrait data; and acquiring virtual information corresponding to the target portrait data, and superimposing the virtual information on the video information. This implementation can identify the current state of the target based on the image information and sound information of the target, and fuse the two identification results to obtain an accurate target portrait. Based on the target portrait, virtual information display matching the user status can be displayed, thereby improving augmented reality and user experience.
