However, compared with intersection detection or visual place recognition, intersection re-identification (intersection re-ID) strongly affects driving behavior decisions with given routes, yet has long been neglected by researchers. This paper strives to explore intersection re-ID by a monocular camera sensor. We propose a Hybrid Double-Level re-identification approach which exploits two branches of Deep Convolutional Neural Network to accomplish multi-task including classification of intersection and its fine attributes, and global localization in topological maps. Furthermore, we propose a mixed loss training for the network to learn the similarity of two intersection images. As no public datasets are available for the intersection re-ID task, based on the work of RobotCar, we propose a new dataset with carefully-labeled intersection attributes, which is called \u201cRobotCar Intersection\u201d and covers more than 30,000 images of eight intersections in different seasons and day time. Additionally, we provide another dataset, called \u201cCampus Intersection\u201d consisting of panoramic images of eight intersections in a university campus to verify our updating strategy of topology map. Experimental results demonstrate that our proposed approach can achieve promising results in re-ID of both coarse road intersections and its global pose, and is well suited for updating and completion of topological maps.<\/jats:p>","DOI":"10.3390\/s20226515","type":"journal-article","created":{"date-parts":[[2020,11,16]],"date-time":"2020-11-16T21:48:52Z","timestamp":1605563332000},"page":"6515","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Traffic Intersection Re-Identification Using Monocular Camera Sensors"],"prefix":"10.3390","volume":"20","author":[{"given":"Lu","family":"Xiong","sequence":"first","affiliation":[{"name":"Institute of Intelligent Vehicles, School of Automotive Studies, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7328-5508","authenticated-orcid":false,"given":"Zhenwen","family":"Deng","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Vehicles, School of Automotive Studies, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6723-5582","authenticated-orcid":false,"given":"Yuyao","family":"Huang","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Vehicles, School of Automotive Studies, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Weixin","family":"Du","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Vehicles, School of Automotive Studies, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiaolong","family":"Zhao","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Vehicles, School of Automotive Studies, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chengyu","family":"Lu","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Vehicles, School of Automotive Studies, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5085-7219","authenticated-orcid":false,"given":"Wei","family":"Tian","sequence":"additional","affiliation":[{"name":"Institute of Intelligent Vehicles, School of Automotive Studies, Tongji University, Shanghai 201804, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,11,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1109\/TRO.2015.2496823","article-title":"Visual place recognition: A survey","volume":"32","author":"Lowry","year":"2016","journal-title":"IEEE Trans.
