Pedestrian re-identification method and device and electronic equipment

The invention provides a pedestrian re-identification method, a pedestrian re-identification device and electronic equipment. According to the method, background filtering is carried out through key point detection, and then the image after background filtering is used as the input of the pedestrian re-identification model to carry out pedestrian re-identification, so that the problem of difficult pedestrian re-identification matching caused by background influence in pedestrian re-identification can be solved, the accuracy of pedestrian re-identification is improved, and the pedestrian re-identification efficiency is improved. Moreover, the architecture of the pedestrian re-recognition model does not need to be changed, and the complexity and training cost of the pedestrian re-recognition model are not increased. 本发明提供一种行人重识别方法、装置及电子设备。所述方法通过关键点检测进行背景过滤，再将背景过滤后的图像作为行人重识别模型的输入，进行行人重识别，能够解决行人重识别中的背景影响导致行人重识别匹配困难的问题，提升行人重识别的准确性，且无需改变行人重识别模型本身的架构，不会增加行人重识别模型的复杂度及训练成本。
