An unmarked augmented reality system based on passive RFID

Abstract

The invention discloses an unmarked augmented reality system based on passive RFID. The unmarked augmented reality system is used for assisting in managing equipment, materials and the like. The method comprises the following steps: establishing a database of equipment or materials, wherein the content stored in the database comprises geometric information (such as virtual 3D models, shapes, sizesand the like) of objects, text information (such as materials, manufacturers, maintenance information and the like) and position information; Positioning and information reading and writing are carried out through an unmarked RFID technology; An application program based on the augmented reality technology is designed and developed, different devices (such as a smart phone, a tablet personal computer and augmented reality glasses) are used for checking related information of an object, and interaction with an object database is carried out. accurate positioning is carried out by utilizing a passive RFID technology, a convenient and efficient information reading and writing method is provided for a user by using a virtuality and reality combined augmented reality technology, and a management platform supporting multi-user cooperation is matched, so that the daily management efficiency of people on equipment and commodities is greatly improved.

Description

technical field [0001] The invention relates to the field of augmented reality technology, in particular to a tagless augmented reality system based on RFID positioning and information reading and writing. Background technique [0002] With the rapid development of construction, manufacturing, logistics and other industries, the diversity and complexity of equipment control and material management have increased significantly, making it difficult for managers to grasp the location and status of all equipment and materials in real time. Therefore, the field of equipment and material management needs to refer to more Effective techniques and means to improve management efficiency. [0003] Augmented reality technology can put digital information (such as virtual models, pictures, animations, information panels, etc.) It can provide better visualization effects and information acquisition methods for equipment material managers. Augmented reality technology is divided into ma...

AI Technical Summary

Problems solved by technology

Augmented reality technology is divided into marker-based augmented reality and marker-free augmented reality. Marker-based augmented reality requires the use of specific markers (such as QR codes, barcodes, identification pictures, etc.) to calibrate the relative positional relationship between the virtual content and the real environment. However, it requires that all marks be visible to users, otherwise the marks cannot be recognized. However, in the management of bulk materials or intensive equipment, it is difficult for managers to access all objects (such as goods that are pressed below, pipes above the suspended ceiling of houses, and inside walls. steel bars, etc.)
