In this paper, an improved AMCL algorithm is proposed, aiming to build a laser radar\u2010based robot localization system in a complex and unstructured environment, with a LIDAR point cloud scan\u2010matching process after the particle score calculating process. The weighted mean pose of AMCL particle swarm is used as the initial pose of the scan matching process. The LIDAR point cloud is matched with the probability grid map from coarse to fine using the Gaussian\u2010Newton method, which results in more accurate poses. Moreover, the scan\u2010matching pose is added into the particle swarm as a high\u2010weight particle. So the particle swarm after resampling will be more concentrated in the correct position. The particle filter and the scan\u2010matching process form a closed loop, thus enhancing the localization accuracy of mobile robots. The experiment results demonstrate that the proposed improved AMCL algorithm is superior to the traditional AMCL algorithm in the complex and unstructured environment, by exploiting the high\u2010accuracy characteristic of scan matching while inheriting the stability of AMCL.<\/jats:p>","DOI":"10.1155\/2018\/2327637","type":"journal-article","created":{"date-parts":[[2018,12,11]],"date-time":"2018-12-11T23:30:31Z","timestamp":1544571031000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":43,"title":["An Improved AMCL Algorithm Based on Laser Scanning Match in a Complex and Unstructured Environment"],"prefix":"10.1155","volume":"2018","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8801-0972","authenticated-orcid":false,"given":"Gang","family":"Peng","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5576-3633","authenticated-orcid":false,"given":"Wei","family":"Zheng","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7148-1011","authenticated-orcid":false,"given":"Zezao","family":"Lu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5119-113X","authenticated-orcid":false,"given":"Jinhu","family":"Liao","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0389-7103","authenticated-orcid":false,"given":"Lu","family":"Hu","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gongyue","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9766-1598","authenticated-orcid":false,"given":"Dingxin","family":"He","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2018,12,11]]},"reference":[{"key":"e_1_2_9_1_2","first-page":"5","article-title":"Research of the laser navigation system for the intelligent patrol robot","volume":"27","author":"Xiao P.","year":"2012","journal-title":"Zidonghuayu Yibiao\/ Automation & Instrumentation"},{"key":"e_1_2_9_2_2","doi-asserted-by":"crossref","unstructured":"ZhaoS.
