This discrepancy can be due to the sensor noise, deformation of the sensor mount, and other factors. These mismatched coordinates can seriously affect the estimation of a distant object\u2019s position and this error can result in problems with object identification. To overcome these problems, numerous coordinate correction methods have been studied to minimize coordinate mismatching, such as off-line sensor error modeling and real-time error estimation methods. The first approach, off-line sensor error modeling, cannot cope with the occurrence of a mismatched coordinate in real-time. The second approach, using real-time error estimation methods, has high computational complexity due to the singular value decomposition. Therefore, we present a fast online coordinate correction method based on a reduced sensor position error model with dominant parameters and estimate the parameters by using rapid math operations. By applying the fast coordinate correction method, we can reduce the computational effort within the necessary tolerance of the estimation error. By experiments, the computational effort was improved by up to 99.7% compared to the previous study, and regarding the object\u2019s radar the identification problems were improved by 94.8%. We conclude that the proposed method provides sufficient correcting performance for autonomous driving applications when the multi-sensor coordinates are mismatched.<\/jats:p>","DOI":"10.3390\/s19092006","type":"journal-article","created":{"date-parts":[[2019,4,29]],"date-time":"2019-04-29T07:01:22Z","timestamp":1556521282000},"page":"2006","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Fast Online Coordinate Correction of a Multi-Sensor for Object Identification in Autonomous Vehicles"],"prefix":"10.3390","volume":"19","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9521-812X","authenticated-orcid":false,"given":"Wooyoung","family":"Lee","sequence":"first","affiliation":[{"name":"Autonomous Driving Platform Team, Hyundai Motor Company, Seoul 06797, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5814-9455","authenticated-orcid":false,"given":"Minchul","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Automotive Engineering, Hanyang University, Seoul 04763, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3505-6675","authenticated-orcid":false,"given":"Myoungho","family":"Sunwoo","sequence":"additional","affiliation":[{"name":"Department of Automotive Engineering, Hanyang University, Seoul 04763, Korea"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0543-2198","authenticated-orcid":false,"given":"Kichun","family":"Jo","sequence":"additional","affiliation":[{"name":"Department of Smart Vehicle Engineering, Konkuk University, Seoul 05029, Korea"}]}],"member":"1968","published-online":{"date-parts":[[2019,4,29]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1239","DOI":"10.1109\/TPAMI.2009.122","article-title":"Survey of pedestrian detection for advanced driver assistance systems","volume":"32","author":"Geronimo","year":"2010","journal-title":"IEEE Trans.
