本論文設計與實現一部全自動化智慧型購物車。主要構想在於改裝大賣場的手推式購物車，使其能夠自動驅動，以實現即時跟隨購物者、計算購物者的消費金額兩大主要功能。我們將手推式購物車加裝輪圈馬達，配合軟硬體開發和機構設計而建構出可自動驅動的購物車系統。另外再配置筆記型電腦與攝影機，應用影像處理技術以辨識購物者穿著衣物，在購物者完全無佩戴任何裝置的狀態下，由模糊控制理論實現購物車即時跟隨購物者的功能。另外購物車上又添置紅外線條碼機，讓購物者可刷讀任何商品條碼以獲取商品訊息和價格，並且自動計算購買金錢總額供購物者作為消費參考。最後到大賣場實際實驗去驗證所有功能，並有很成功的實驗成果。這種智慧型購物車，若真開發上市，必然會讓購物更加輕鬆便利。This thesis designs and realizes an intelligent shopping cart which not only can follow the desired customer but also can calculate the customer’s consumption price. First, two rim motors are installed as the rear wheels in a common shopping cart such that the shopping cart can be automatically driven. A notebook and a camera are set on the shopping cart for the image processing of cloth recognition, and then the desired customer can be identified without wearing any extra equipment device. Based on the image processing result, fuzzy logic controllers are designed to achieve the real-time customer being followed with a fixed and certain distance. Furthermore, a barcode reader is added such that the shopping cart can read in product information by barcode reading. In the notebook, a human interface is built to show the consumption items and the total price for all goods. Integrating the hardware and software designs, the intelligent shopping cart can be completed for the convenience of customers. Finally, some practical experiments are given to demonstrate that the intelligent shopping cart can work well in a real shopping mall.
