An Intelligent Shopping System based on UHF RFID

In the context of COVID-19, in order to solve the problems that customers need to spend more energy to find products in the supermarket, long checkout queue time, and cumbersome product management, optimize the shopping route of customers, accelerate the shopping process, and reduce the risk of infection; providers exceed Supplier’s sales of goods, and then timely and purposeful selection of goods, simplifying the supply chain process between supermarkets and suppliers. This article designs a multi-terminal interactive intelligent shopping system based on UHF RFID to construct The shopping cart terminal, mobile phone APP terminal, data management system terminal, and three-terminal interactive system with RFID technology as the core are developed. The design uses the UHF RFID system to identify the information in the electronic tags of the goods, and through the navigation function, helps customers locate the desired goods, and realizes the functions of identification, information display, navigation and positioning, and settlement.

Large Relics Scenario-Based Visualization Using Head-Mounted Displays

Most visitors come to visit museums; in reality, few immersive solutions support the senses experience. Virtual reality (VR) technology attaches the virtual information from the real environment. Applying the VR technology in the 3D relic information display and visualization in the museum field is a hot research issue. However, most current solutions of relics are one-sided, only focusing on the virtual exhibition, lack of associations with actual function, and senses experience, especially the large artistic cultural relics. The scenario-based virtual exhibition solution is an available approach to allow visitors to imitate ancient artist and provide relatively experience in the form of content and sense organ of ancient art. It converts large relics into “digital large relics” and enables experiencing performance of ancient civilization in person. The solution presents relics to the visitors in a more direct and vivid manner and with innovative forms, strong interaction, and intelligence, thereby improving the interests and satisfaction among visitors in this type of relic exhibition. Besides, it also provides visitors with a convenient way to experience and learn ritual and culture. Evaluation and conclusion can be drawn that most participants appreciated this solution in clear interface and completion aspects.

Development of a smart geoinformation system module for forest taxing data processing

The authors of the article offer a specialized geoinformation system for use in forestry. A distinctive feature of the proposed system is the use of data processing module included in the GIS. Forestry requires to improve the quality of management and monitoring of forest resources, to enhance the perception of geoinformation in a user friendly form. One of the perspective technologies of geospatial information display is infograms displaying the evaluation of the territory under analysis. Such way of display requires a specialized interface, technologies of processing and data interpretation included in structure of the program, and specific characteristics of the system offered by the authors of this work.

A prototype of parking space information system based on Image Processing

An automatic parking system has been proposed to make the car parking process more efficient in terms of time and cost. The absence of information on the position of the parking lot makes the car driver take longer to find it. In multi-story parking lots, officers cannot constantly monitor the available parking conditions directly, so prospective parking users do not know the position of the open parking space. In addition, many parking lots use automatic door latch, but no parking space information display. Parking system automation can be based on hardware, software, or a combination of hardware and software. To the best of our knowledge, no software-based framework is entirely used on this system. Therefore, this study proposes an automatic parking system based on camera sensors and software, which is combined into an information system. The proposed method uses simple morphological operations. Based on the test results, the detection accuracy achieved is 100% with a light intensity of 3 lux, 15 lux, 30 lux, 60 lux, 120 lux, and 250 lux. The average processing time is 1.59 seconds. From this study, it is hoped that this prototype can be tested on relevant environmental conditions so that the prototype can be implemented in parking lots.
