Abstract

The invention discloses an indoor positioning device and an indoor positioning system. The indoor positioning device comprises a first receiver, a storage and a processor, wherein the first receiver is used for receiving optical signals emitted by lighting lamps; different lighting lamps emit different optical signals which correspond to different coded information; the storage is used for storing an indoor map and a corresponding relation of decoded information and address information; the address information is used for indicating the address of a lighting lamp in the indoor map; and the processor is connected to the first receiver and the storage respectively and is used for processing the optical signals to obtain the decoded information corresponding to the coded information and searching address information corresponding to the decoded information in the storage. By the invention, the positioning accuracy and timeliness are ensured.

Description

technical field [0001] The present invention relates to the field of positioning, in particular to an indoor positioning device and system. Background technique [0002] The indoor positioning device in the prior art needs to rely on the global indoor positioning device (GPS) to determine the current position. 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 indoor positioning devices need to be within the direct line of sight of GPS satellites to work, so when entering areas such as shopping malls or underground parking lots, GPS positioning has just lost its effectiveness. [0003] For the problem that the indoor positioning device in the prior art cannot be used indoors, no effective solution has been proposed yet. Contents of the...
