Therefore, this paper is an in-depth study of\u0000estimating body sizes from two-dimensional images in a self-collected database of human body samples. First, the\u0000artificial thresholds in the Canny edge operator were replaced by adaptive thresholds. The improved Canny edge\u0000operator was combined with mathematical morphology so that it could detect a clear and complete single human\u0000contour. Then a joint point detection algorithm based on a convolution neural network and human proportion is\u0000proposed. It can detect human feature points with different body proportions. Finally, front and side images and manual\u0000body measurements of 122 males aged 18–22 years were collected as the human sample database, calculating the\u0000length and fit of the girth size. Compared with manual body measurement data, the error of human length and girth size\u0000parameters within the national standard range of –1.5 ~ 1.5 cm can reach 91% on average. This study provides an\u0000accurate and convenient anthropometric method for digital garment engineering, which can be used for online shopping\u0000and garment customization, and has a certain practical value.","PeriodicalId":13638,"journal":{"name":"Industria Textila","volume":" ","pages":""},"PeriodicalIF":1.4,"publicationDate":"2023-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43806613","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
