Design And Implementation Of Intelligent Express Cabinet Terminal System Based On Machine Vision

With the popularity of e-commerce,the express industry entered a rapid development stage,but with the increase of the express quantity,the issue of "man and man" caused by the courier when they were unable to sign in time,and courier service network of high cost and the problems of safety delivery have become increasingly prominent.This paper designs and implements an intelligent express cabinet terminal system,which solves the problem of low efficiency of express delivery and secure express temporary storage.At the same time,OCR technology is applied to realize the function of automatic acquisition of express information,and lighten the operation burden of couriers.Firstly,summarizes the development status of domestic and foreign intelligent express cabinet and machine vision technology in the field of optical character recognition,introduces the composition of the existing intelligent express cabinet system,the smart courier cabinet terminal system requirements analysis,put forward the improvement scheme based on OCR technology in the lack of existing smart courier cabinet terminal system.And ultimately determine the framework of intelligent express cabinet terminal system this time.Secondly,according to the system framework,the storage cabinet control system,the automatic identification algorithm and the human-computer interaction software in the system were designed and realized.The storage cabinet control system is composed of the inspection device of the article and the control board of the cabinet,and completes the function of the control of the box door of the storage cabinet and the detection of the objects in the cabinet.The automatic identification algorithm of express order is implemented based on Open CV.After SURF's feature matching is used to complete the geometric correction of the express order,the number of the express number and the receiver number is identified,respectively,in which the SVM classifier is used to identify the phone number.The human-computer interaction software is based on Qt.Through the operation of image acquisition unit,wireless data transmission unit,locker control system and human-machine interaction interface,the business process of intelligent express terminal is realized.Finally,the intelligent express cabinet terminal system is tested.It is mainly about the output signal test of the device detection device,the function test of the cabinet control panel,and the detailed test cases are compiled with the help of the hour pointer to test the business process of the system.The test results show that all the functions are in conformity with the design requirements.
