Problems solved by technology

[0004] Most of the ordering systems on the existing market are for merchants. After users make ordering decisions by reading simple paper menu information, waiters help users place orders and manage orders through PDAs, mobile devices or PCs; this experience Definitely not friendly enough to provide users with real-time, useful information

Embodiment

[0030] The present invention provides a user-oriented self-service ordering system based on augmented reality, the system includes a mobile client ( figure 1 3) and background system ( figure 1 5), the mobile client of the system can run on mainstream mobile operating system platforms, such as Android and iOS. The whole system, including the mobile client and the background system, will be implemented with a three-tier architecture, such as figure 2 shown.

[0031] Among them, the mobile client ( figure 1 3) uses augmented reality technology, which obtains the menu on the plane medium through the camera ( figure 1 1) in the image, using augmented reality technology to identify the logo on the menu ( figure 1In 2) recognition and tracking, the real-world coordinates where the sign is located are calculated in real time and the virtual information and resources of the dishes are superimposed on the image, so that users feel that these information exist in the real world.

[0053] (1) Implementation of the system support layer:

[0054] Identity recognition module:

[0055] Import Vuforia SDK into Unity, and add ARCamera, ImageTarget and CloudRecognition objects to Hierarchy. Add a C# script component to ImageTarget. The script implements the OnTrackerableStateChanged callback method of ITrackableHandler. If the recognition is successful, call the OnTrackingFound method and the dish information processing module, otherwise call the OnTrackingLost method. Add a C# script component that implements the ICloudEventHandler interface to the Cloud Recognition object, and implement the corresponding recognition cycle function in the script to identify and track the logo: instantiate an Object Tracker in the OnInitilized method to detect the recognition situation; in OnStateChanged, determine whether the current In the recognition state, if it is, call the OnTrackingLost method of ImageTarget; in OnNewSearchResult, compare the recognized identification i...

Abstract

The invention provides a self-service dish-ordering system based on augmented reality, and the system comprises a mobile client and a background system. The mobile client and the background system are respectively divided into a system supporting layer, a service processing layer and a user interaction layer. The mobile client provides a visual interface through carrying out the real-time superposing of virtual dish information and a real world image and displaying the superposed image to a user. The system supporting layers are mainly responsible for the recognition and tracking of an identification, and have functions of resource file management, file management, database and network communication. The service processing layers mainly achieve the functions of dish information superposed display, user logging-in, comment scoring, order management, mobile payment and dish information management according to a dish-ordering flow. The user interaction layers are interactive interfaces for software and the user, and carry out the call of interfaces, provided by the service processing layers according to the operation of the user, to make a response. The system can provide a decision-making reference for the user through employing multimedia and social information, and enables the dish-ordering process to be more convenient, quick, interesting and friendly.

Description

technical field [0001] The invention relates to the realization of a self-service ordering system using Vuforia SDK augmented reality technology. More specifically, the system includes identification identification, virtual information display and interaction, user ordering, mobile payment, etc., and belongs to the field of human-computer interaction. Background technique [0002] The Vuforia SDK released by Qualcomm for building augmented reality was acquired by American Parametric Technology Corporation (PTC) in October 2015. This SDK can be developed based on the Unity development tool, and its technical indicators such as pattern recognition, recognition tracking, and picture quality are in a leading position in the industry, providing strong support for the implementation of the present invention. [0003] Unity3D is a multi-platform comprehensive game development tool developed by Uinty Technologies for building interactive content such as 3D video games, architectural...
