Abstract

The invention discloses a navigation device and a system, wherein the navigation device comprises a first receiver, a memory, a second receiver and a processor; the first receiver is used for receiving optical signals emitted by illuminating lamps; different illuminating lamps emit different optical signals; different optical signals correspond to different coding information; the memory is used for storing an indoor map and corresponding relationship between decoding information and address information; the second receiver is used for receiving address information of destination; the processor is respectively connected to the first receiver, the memory and the second receiver and used for processing the optical signals to obtain the decoding information corresponding to the coding information, finding out the address information of the illuminating lamps corresponding to the decoding information in the memory, and determining a navigation route on the indoor map according to the address information of the destination and the address information of the illuminating lamps; and the navigation route is the route from the address corresponding to the illuminating lamps to the address corresponding to the destination. By means of the invention, the navigation accuracy is ensured.

Description

technical field [0001] The present invention relates to the field of navigation, in particular to a navigation device and system. Background technique [0002] Navigation systems in the prior art need to rely on the Global Positioning System (GPS) to determine the current location. Generally speaking, GPS needs to know the longitude and latitude of the object to be measured. In some special cases, it is necessary to know the altitude to locate accurately. With these three sets of data, the accuracy of GPS positioning can generally reach 2 to 3 meters. Since existing navigation systems need to be within the direct line of sight of GPS satellites to work, so when entering areas such as underground parking lots, GPS navigation has just lost its effectiveness. [0003] For the problem that the navigation device in the prior art cannot be used indoors, no effective solution has been proposed yet. Contents of the invention [0004] The present invention provides a navigation...
