Problems solved by technology
In addition, general open electronic map data cannot effectively present detailed map information or structural features of indoor spaces or buildings, which limits the positioning and navigation effects that general navigation devices can produce
[0006] Although the ground map on which a specific space or building is based can be provided by the industry, GPS technology can be used for positioning and navigation, but as far as the operation in the vertical direction between different floors is concerned, GPS technology still has large errors and is not easy. The actual situation of use
In addition, for a large-scale factory building with automatic production equipment or a highly complex display environment in the space, the movement of the automatic machine tool on a specific path must have a highly accurate spatial correspondence, and even the error It must be within a few centimeters; for this, there are still considerable difficulties in the application of GPS technology

The invention discloses a position fixing navigation system by utilizing an identification label and a method, which is applied to an area which are distributed with a plurality of the identification labels and is used for fixing the position and navigation of a mobile device, so as to effectively obtain the needed position fixing signals and further navigation service in a common indoor area. The system comprises a plurality of the identification labels and the mobile device; in the method, the unique position data of at least one identification label is read, the position information of the mobile device is generated according to the unique position data of at least one identification label and the geospatial data of the area; wherein the unique position data of each identification label in a plurality of the identification labels corresponds to the coordinate position of the geospatial data of the area where each identification label exists.
Description
technical field [0001] The present invention relates to a positioning and navigation system using an identification tag and a positioning and navigation method applied thereto, in particular to a system and method for positioning and navigating with a radio frequency identification technology data reading function and targeting the position of the identification tag. Background technique [0002] With the continuous progress and development of electronic digital technology, modern people often use various electronic devices or products with different application functions in their daily life. For example, the advancement of mobile computing technology has produced portable electronic devices or mobile computing device products such as mobile phones, smart phones, personal digital assistants, or notebook computers, which bring users considerable convenience and practicability. [0003] In addition, the navigation function of the navigation system has also been widely used in ...
