Embodiment Construction

[0075] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, but not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art based on the present application fall within the protection scope of the present application.

[0076] Object re-recognition: also known as object re-recognition, is a technology that uses computer vision technology to determine whether a specific object exists in an image or video sequence.

[0077] The object re-identification method in the related art focuses on features such as the body and clothing of the object. However, in complex scenes such as scenes where objects change clothes, and scenes where hairstyles or exterior d...

Abstract

The embodiment of the invention provides an object re-identification method and device, electronic equipment and an object re-identification system, and the method comprises the steps of obtaining a to-be-recognized image which comprises a to-be-recognized object; determining a first quality score of a body area of the to-be-recognized object in the to-be-recognized image, and determining a second quality score of a face area of the to-be-recognized object in the to-be-recognized image; determining a first similarity between the body area and the body area of the target object, and determining a second similarity between the face area and the face area of the target object; determining a matching score of the to-be-identified object and the target object according to the first quality score, the second quality score, the first similarity and the second similarity; and according to the matching score, determining whether the to-be-identified object and the target object are the same object. Thus, object re-identification in a more complex scene can be well coped with, the generalization performance of object re-identification is greatly improved, and the accuracy of object re-identification is further improved.

Description

technical field [0001] The present application relates to the technical field of monitoring, in particular to an object re-identification method, device, electronic equipment and object re-identification system. Background technique [0002] The construction of smart cities and safe cities is inseparable from monitoring equipment scattered in various public places, and with the extensive deployment and control of monitoring equipment, a large number of monitoring equipment has produced a large number of surveillance videos. Based on this, how to identify specific objects in surveillance video is an important technical node of intelligent security. This method of judging whether a specific object exists in an image or video sequence based on computer vision technology is called an object re-identification method. [0003] In the object re-identification method in the related art, since the characteristics of the object's body and clothing are easy to repeat, the accuracy rat...
