澳大利亚地区消费者脚型数据对应运动鞋尺码预测数据
收藏资源简介：
中国制造的运动鞋正通过亚马逊、全球速卖通等平台销往全世界不同的国家，不同国家的消费者脚型对应合脚的运动鞋尺码存在差异。通过将三维足部扫描测量算法模型接入线上商城以采集澳大利亚消费者的足长、足宽、足弓高和跖围等脚型数据，经过三维建模还原以及足鞋数据匹配，分析预测出最适合澳大利亚消费者脚型的运动鞋尺码。帮助开展运动鞋出口销售业务的企业降低由于鞋不合脚导致的销售退换货率，同时减少退货换货过程的运费成本。1.数据采集：澳大利亚国家的消费者在买运动鞋前使用手机拍摄3张自己的足部脚型照片上传至系统；2.数据处理：根据澳大利亚国家的消费者上传的照片调用三维足部扫描测量算法模型，使用YOLO图像识别模型识别出消费者的脚型图像，再调用RCF边缘检测算法，从照片中完整提取消费者的完整脚型。根据用户填写的尺码数据，进行三维建模还原足部完整形态；在还原过程中可能出现图像缺口，按照尺码±0.5码处理，阈值限制为±1码，还原最小缺口的三维足部模型；3.数据分析与预测：根据足部三维建模结果，基于二分法规则等比例分析计算出消费者的实际足部尺寸数据，参考国际标准的足鞋尺码对应表预测出该消费者足部尺寸对应的最合脚的运动鞋尺码。
Sports shoes manufactured in China are sold to consumers across different countries worldwide via platforms such as Amazon and AliExpress. There are discrepancies in the proper sports shoe sizes corresponding to the foot shapes of consumers from different countries. By integrating the 3D foot scanning and measurement algorithm model into the online mall to collect foot shape data including foot length, foot width, arch height and metatarsal circumference of Australian consumers, and after 3D modeling restoration and foot-shoe data matching, the system analyzes and predicts the most suitable sports shoe size for the foot shape of Australian consumers. This helps enterprises engaged in sports shoe export sales reduce the return and exchange rate caused by ill-fitting shoes, as well as the freight costs incurred during the return and exchange process. 1. Data Collection: Australian consumers upload 3 photos of their feet taken with mobile phones to the system before purchasing sports shoes. 2. Data Processing: Call the 3D foot scanning and measurement algorithm model based on the photos uploaded by Australian consumers. First, use the YOLO image recognition model to identify the consumer's foot shape images, then invoke the RCF edge detection algorithm to completely extract the complete foot shape from the photos. Perform 3D modeling to restore the complete foot shape based on the size data filled in by the user. If image gaps appear during the restoration process, handle them with a size deviation of ±0.5, with a threshold limit of ±1 size, and restore the 3D foot model with the minimal gap. 3. Data Analysis and Prediction: Based on the results of the 3D foot modeling, use the dichotomy rule to proportionally analyze and calculate the actual foot size data of the consumer, and refer to the international standard foot-shoe size correspondence table to predict the most suitable sports shoe size matching the consumer's foot size.
