Abstract

The invention discloses a multidimensional characteristic passenger re-identification method, a device, a storage medium and a processor, wherein the method comprises the steps of establishing a firstconvolutional neural network model according to a preset multidimensional characteristic extracting method; training a first convolutional neural network model according to a preset public data set,and obtaining a second convolutional neural network model; training a model group which is composed of the second convolutional neural network model according to a preset ternary set data set, and obtaining a third convolutional neural network model, wherein the model group comprises three parallel second convolutional neural network models; inputting a target passenger image and a to-be-identified passenger image to a third convolutional neural network model, thereby obtaining a target passenger characteristic vector and a to-be-identified passenger characteristic vector; and calculating a vector distance between the target passenger characteristic vector and the to-be-identified passenger characteristic vector, and obtaining an identification result according to the vector distance. Themultidimensional characteristic passenger re-identification method, the device, the storage medium and the processor settle a technical problem of relatively low identification precision in the passenger re-identification mode in prior art.

Description

technical field [0001] The present invention relates to the field of video image processing, in particular to a method, device, storage medium and processor for multi-scale feature pedestrian re-identification. Background technique [0002] Pedestrian re-identification technology, that is, the technology of automatically retrieving target pedestrians between camera videos from multiple perspectives without overlapping overlaps, plays a vital role in applications such as intelligent video surveillance and suspect retrieval. However, due to the influence of camera viewing angle differences, pedestrian pose changes, and early detection errors, the pedestrian re-identification problem has great challenges. [0003] The existing pedestrian re-identification technology, by extracting the global and local features of pedestrians, alleviates the impact caused by posture changes and detection errors. Patent CN104376334A proposes a pedestrian comparison method based on multi-scale fe...
