However, the captured stripe images can show high-dynamic characteristics of low signal-to-noise ratio and uneven brightness due to the complexity of the onsite environment. These conditions seriously affect measurement reliability and accuracy. In this study, a wheel size measurement framework based on a structured-light vision sensor, which has high precision and reliability and is suitable for highly reflective conditions, is proposed. Initially, the quality evaluation criterion of stripe images is established, and the entire stripe is distinguished into high- and low-quality segments. In addition, the multi-scale Retinex theory is adopted to enhance stripe brightness, which improves the reliability of subsequent stripe center extraction. Experiments verify that this approach can remarkably improve measurement reliability and accuracy and has important practical value.<\/jats:p>","DOI":"10.3390\/s18124296","type":"journal-article","created":{"date-parts":[[2018,12,7]],"date-time":"2018-12-07T03:46:14Z","timestamp":1544154374000},"page":"4296","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Reliable and Accurate Wheel Size Measurement under Highly Reflective Conditions"],"prefix":"10.3390","volume":"18","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8786-9347","authenticated-orcid":false,"given":"Xiao","family":"Pan","sequence":"first","affiliation":[{"name":"Ministry of Education Key Laboratory of Precision Opto-Mechatronics Technology, Beihang University, Beijing 100083, China"}]},{"given":"Zhen","family":"Liu","sequence":"additional","affiliation":[{"name":"Ministry of Education Key Laboratory of Precision Opto-Mechatronics Technology, Beihang University, Beijing 100083, China"}]},{"given":"Guangjun","family":"Zhang","sequence":"additional","affiliation":[{"name":"Ministry of Education Key Laboratory of Precision Opto-Mechatronics Technology, Beihang University, Beijing 100083, China"}]}],"member":"1968","published-online":{"date-parts":[[2018,12,6]]},"reference":[{"key":"ref_1","unstructured":"Huh, S., Shim, D.H., and Kim, J.
