Person re-identification（Re-ID） aims to study the matching of specific persons among multiple disjoint cameras.To the best of our knowledge, it's the first work that uses the types of challenges that the Re-ID technology needs to overcome in complex scenes as the classification basis, and classifies the Re-ID articles published during 2010-2021 into seven categories: person posture issues, occlusion issues, lighting issues, viewpoint issues, background issues, resolution issues and other open issues.This classification method is convenient for researchers to start from actual needs and find corresponding solutions according to the problems.Firstly, it reviews the research background, significance and research status of Re-ID,summarizes the current mainstream Re-ID framework, counts the papers published in the three top conferences of computer vision, i.e.CVPR,ICCV and ECCV,and counts the Re-ID related projects in the national fund projects since 2013.Secondly, with regard to the seven types of challenges face
