Abstract

The invention relates to a target tracking method and device, an event detection method and device, electronic equipment and a storage medium. The target tracking method comprises the steps: carrying out the face recognition of an object in a video stream, determining a to-be-tracked object in the video stream, and determining a to-be-tracked identifier of the to-be-tracked object; determining whether a to-be-tracked identifier is included in a target library, the target library including a tracking identifier of a reference tracking object and face feature information of the reference tracking object; under the condition that the to-be-tracked identifier is not included in the target library, performing feature matching based on the extracted face feature information of the to-be-tracked object and the face feature information of the reference tracking object; and under the condition that the face feature information of the to-be-tracked object is successfully matched with the face feature information of the reference tracking object, performing association tracking on the to-be-tracked object and the reference tracking object with the successfully matched features, wherein the association tracking is used for associating the tracking data of the to-be-tracked object with the tracking data of the reference tracking object with the successfully matched features.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular to a target tracking and event detection method and device, electronic equipment and a storage medium. Background technique [0002] Face recognition is widely used in many different fields, such as security monitoring, face access control, Internet entertainment and so on. In addition, based on face recognition, continuous tracking of the target object can be achieved. However, face recognition needs to meet certain lighting conditions, and / or, needs the tracked object to meet certain pose conditions in order to achieve a satisfactory recognition rate. In the case where a large area of ​​the face of the tracked object is not visible, such as turning sideways or bowing the head, face recognition will be interrupted, and the tracked object will be lost, making it impossible to meet the needs of long-term continuous tracking. Contents of the invention [0003] The d...
