At present, the manual measurement method is the main measure of contact depth, which has the problems of low efficiency and strong subjectivity. The measurement of contact depth based on machine vision includes two steps: moving and static contact positioning and distance conversion. The positioning result will have an important impact on distance measurement. Therefore, a positioning method for moving and static contact based on double\u2010layer Mask R\u2010CNN (DLM) is proposed in this paper: first, the moving contact is roughly positioned by Mask R\u2010CNN to obtain the predicted target area; second, the subgraph of the target area is preprocessed; finally, the precise positioning is used to determine the precise position of the moving and static contact. The accuracy and robustness of the proposed DLM are verified by the internal image of the switch machine.<\/jats:p>","DOI":"10.1155\/2021\/8655499","type":"journal-article","created":{"date-parts":[[2021,8,20]],"date-time":"2021-08-20T02:35:12Z","timestamp":1629426912000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Positioning of the Moving and Static Contacts of the Switch Machine Based on Double\u2010Layer Mask R\u2010CNN"],"prefix":"10.1155","volume":"2021","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4283-6944","authenticated-orcid":false,"given":"Jiacheng","family":"Yin","sequence":"first","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5896-4502","authenticated-orcid":false,"given":"Zhaomin","family":"Lv","sequence":"additional","affiliation":[]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5481-4494","authenticated-orcid":false,"given":"Xingjie","family":"Chen","sequence":"additional","affiliation":[]},{"given":"Kun","family":"Yang","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2021,8,19]]},"reference":[{"key":"e_1_2_9_1_2","doi-asserted-by":"publisher","DOI":"10.1155\/2021\/6687146"},{"key":"e_1_2_9_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.conengprac.2020.104706"},{"key":"e_1_2_9_3_2","doi-asserted-by":"publisher","DOI":"10.1109\/tim.2018.2863999"},{"key":"e_1_2_9_4_2","doi-asserted-by":"publisher","DOI":"10.1109\/jmems.2019.2912869"},{"key":"e_1_2_9_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/jsen.2019.2901125"},{"key":"e_1_2_9_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/tii.2020.2972290"},{"key":"e_1_2_9_7_2","doi-asserted-by":"publisher","DOI":"10.1109\/tip.2018.2813161"},{"key":"e_1_2_9_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/tip.2010.2044957"},{"key":"e_1_2_9_9_2","doi-asserted-by":"publisher","DOI":"10.1007\/s11045-018-0621-1"},{"key":"e_1_2_9_10_2","doi-asserted-by":"crossref","unstructured":"DalalN.andTriggsB.
