Positioning system and method

Abstract

The invention discloses a positioning system and a method. The positioning system comprises a positioning device and a wearable RFID reader-writer; the positioning device is composed of one positioning unit or a plurality of connected positioning units; one or more RFID tags are arranged in each positioning unit; the RFID tags are in one-to-one correspondence with three-dimensional space coordinates in a positioning space; and the wearable RFID reader-writer includes a reader-writer body and a fixing unit, wherein the reader-writer body carries out read-write operation for the RFID tags, and the fixing unit is connected with the reader-writer body so as to fix the reader-writer body in a wearable manner. The invention also discloses a method for carrying out positioning by using the positioning system. According to the positioning system of the invention, space positioning is realized through the RFID tags arranged in the positioning device and the wearable RFID reader-writer, and therefore, the positioning system is just slightly affected by the environment, and is convenient and flexible to install, high in positioning precision and low in cost.

Description

Technical field [0001] The present invention relates to the technical field of spatial positioning, in particular to a positioning system and method. Background technique [0002] With the development of society, the advancement of network and communication technology, graphics and image processing technology, and computer technology, virtual reality (Virtual Reality), a computer simulation system that can create and experience virtual worlds, has been favored by more and more people, becoming human A new way of communication. The most important feature of virtual reality is that it has good interactivity and immersion, and the main technology of interaction and providing immersion relies on high-precision spatial positioning, so as to provide users with a better experience of seamless combination of virtual and real. [0003] The current spatial positioning technologies mainly include: various positioning technologies based on GNSS (Global Navigation Satellite System), radio freq...

Problems solved by technology

Through this kind of technology, we can only judge whether the target object is within the signal coverage area, and cannot accurately determine the specific location information of the target object

[0007] 4. CV positioning technology, although this type of technology has high precision, but the positioning cost is high, and if multiple target objects move or exist in a positioning area at the same time, the positioning accuracy will drop sharply, and it has the disadvantage of weak ID, that is, multiple There may be a phenomenon that some or all of the target objects cannot be identified and located
