The new system must deal with robots and people as dynamic obstacles using LIght Detection And Range (LIDAR) sensor in order to collect the surrounding information. Although robot movement can be easily tracked by an Extended Kalman Filter (EKF), people\u2019s movement is more unpredictable and it might not be correctly linearized by an EKF. Therefore, to deal with a better estimation of both types of dynamic objects in the local map it is recommended to improve our previous work. The DOMap has been extended in three key points: first the LIDAR reflectivity remission is used to make more robust the matching in the optical flow of the detection stage, secondly static and a dynamic occlusion detectors have been proposed, and finally a tracking stage based on Particle Filter (PF) has been used to deal with robots and people as dynamic obstacles. Therefore, our new improved-DOMap (iDOMap) provides maps with information about occupancy and velocities of the surrounding dynamic obstacles (robots, people, etc.) in a more robust way and they are available to improve the following planning stage.<\/jats:p>","DOI":"10.3390\/s20195520","type":"journal-article","created":{"date-parts":[[2020,9,28]],"date-time":"2020-09-28T08:02:58Z","timestamp":1601280178000},"page":"5520","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Improved Dynamic Obstacle Mapping (iDOMap)"],"prefix":"10.3390","volume":"20","author":[{"given":"\u00c1ngel","family":"Llamazares","sequence":"first","affiliation":[{"name":"Department of Electronics, University of Alcal\u00e1, 28801 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Eduardo","family":"Molinos","sequence":"additional","affiliation":[{"name":"Karlsruhe Institute of Technology, 76131 Karlsruhe, Germany"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8875-1866","authenticated-orcid":false,"given":"Manuel","family":"Oca\u00f1a","sequence":"additional","affiliation":[{"name":"Department of Electronics, University of Alcal\u00e1, 28801 Madrid, Spain"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vladimir","family":"Ivan","sequence":"additional","affiliation":[{"name":"Institute of Perception, Action and Behavior, University of Edinburgh, Edinburgh EH8 9YL, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,26]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"569","DOI":"10.1002\/rob.20258","article-title":"Junior: The Stanford Entry in the Urban Challenge","volume":"25","author":"Montemerlo","year":"2008","journal-title":"J.
