When the teeth fall off and enter the crusher with other ore materials, serious damages to crusher gears and other equipment happen, which causes millions of economic loss, because it is made of high\u2010manganese steel. Thus, it is urgent to develop an efficient and automatic algorithm for detecting broken teeth. However, existing methods for detecting broken teeth have little effect and most research studies depended on sensor skills, which will be disturbed by closed cavity in shovel and not stable in practice. In this paper, we present an intelligent computer vision system for monitoring teeth condition and detecting missing teeth. Since the pixel\u2010level algorithm is carried out, the amount of calculation should be reduced to improve the superiority of the algorithm. To release computational pressure of subsequent work, salient detection based on deep learning is proposed for extracting the key frame images from video flow taken by the camera installed on the shovel including the teeth we intend to analyze. Additionally, in order to more efficiently monitor teeth condition and detect missing teeth, semantic segmentation based on deep learning is processed to get the relative position of the teeth in the image. Once semantic segmentation is done, floating images containing the shape of teeth are obtained. Then, to detect missing teeth effectively, image registration is proposed. Finally, the result of image registration shows whether teeth are missing or not, and the system will immediately alert staff to check the shovel when teeth fall off. Through sufficient experiments, statistical result had demonstrated superiority of our presented model that serves more promising prospect in mining industry.<\/jats:p>","DOI":"10.1155\/2021\/6503029","type":"journal-article","created":{"date-parts":[[2021,11,23]],"date-time":"2021-11-23T04:35:08Z","timestamp":1637642108000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":5,"title":["Electric Shovel Teeth Missing Detection Method Based on Deep Learning"],"prefix":"10.1155","volume":"2021","author":[{"given":"Xiaobo","family":"Liu","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9370-4386","authenticated-orcid":false,"given":"Xianglong","family":"Qi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yiming","family":"Jiang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2021,11,22]]},"reference":[{"key":"e_1_2_8_1_2","doi-asserted-by":"publisher","DOI":"10.1080\/13895260412331315553"},{"key":"e_1_2_8_2_2","article-title":"Vieselmeyer","author":"Lee R.","year":"1997","journal-title":"Loader Attachment"},{"key":"e_1_2_8_3_2","article-title":"Simulation on structure strength of bucket teeth in mine loader","author":"Tian C.","year":"2016","journal-title":"Journal of Pingxiang University"},{"key":"e_1_2_8_4_2","doi-asserted-by":"publisher","DOI":"10.1088\/1757-899x\/423\/1\/012055"},{"key":"e_1_2_8_5_2","doi-asserted-by":"publisher","DOI":"10.7474\/TUS.2014.24.1.001"},{"key":"e_1_2_8_6_2","first-page":"3","article-title":"Shovel teeth monitoring and maintenance in open-pit mines hakan schunnesson, hannington nwagalanyi and uday kumar","volume":"14","author":"Schunnesson H.","year":"2011","journal-title":"Condition Monitoring and Diagnostic Engineering Management"},{"key":"e_1_2_8_7_2","article-title":"Optimizing replacement time for mining shovel teeth using reliability analysis and Markov chain Monte Carlo simulation","volume":"35","author":"Sembakutti D.","year":"2017","journal-title":"International Journal of Quality and Reliability Management"},{"key":"e_1_2_8_8_2","doi-asserted-by":"publisher","DOI":"10.4028\/www.scientific.net\/amr.139-141.157"},{"key":"e_1_2_8_9_2","unstructured":"LuoX.andZhangH.
