Abstract

An embodiment of the present disclosure discloses a method and a device for indoor navigation. The method comprises the steps of: receiving an infrared carrier wave sent by an LED lamp and acquiring GPS data codes from the infrared carrier wave; analyzing the GPS data codes and obtaining GPS data; determining a current position according to the GPS data; and planning a navigation route between the current position and a target position according to the current position. The method and the device for indoor navigation provided by the embodiment of the present disclosure may realize indoor positioning and indoor navigation.

First claim

What is claimed is:

1 . A method for indoor navigation, comprising:
receiving an infrared carrier wave sent by an LED lamp and acquiring GPS data codes from the infrared carrier wave; analyzing the GPS data codes and obtaining GPS data; determining a current position according to the GPS data; planning a navigation route between the current position and a target position according to the current position.

2 . The method according to claim 1 , wherein, before receiving an infrared carrier wave sent by an LED lamp and acquiring GPS data codes from the infrared carrier wave, the method further comprises:
modulating the GPS data codes onto the carrier wave through a code modulation technology, transmitting the carrier wave modulated with GPS data codes through the infrared transmitter-receiver of the LED lamp, and generating the infrared carrier wave.

3 . The method according to claim 1 , wherein receiving the infrared carrier wave sent by the LED lamp comprises:
receiving the infrared carrier wave at a frequency identical with the infrared carrier wave.

4 . The method according to claim 3 , wherein, the infrared carrier wave is a 38 KHz carrier wave.

5 . The method according to claim 1 , wherein, the GPS data codes are 50 Hz data codes.

6 . An electronic device, comprising:
at least one processor; and a memory communicably connected with the at least one processor for storing instructions executable by the at least one processor, wherein execution of the instructions by the at least one processor causes the at least one processor to: receive an infrared carrier wave sent by an LED lamp and acquire GPS data codes from the infrared carrier wave: analyze the GPS data codes and obtain GPS data; determine a current position according to the GPS data; plan a navigation route between the current position and a target position according to the current position.

7 . The electronic device according to claim 6 , wherein execution of the instructions by the at least one processor causes the at least one processor to further:
modulate the GPS data codes onto the carrier wave through a code modulation technology, transmit the carrier wave modulated with GPS data codes through the infrared transmitter-receiver of the LED lamp, and generate infrared carrier wave.

8 . The electronic device according to claim 6 , wherein, receive an infrared carrier wave sent by an LED lamp and acquiring GPS data codes from the infrared carrier wave comprises:
receiving the infrared carrier wave at a frequency identical with the infrared carrier wave.

9 . The electronic device according to claim 8 , wherein, the infrared carrier wave is 38 KHz carrier wave.

10 . The electronic device according to claim 6 , wherein, the GPS data codes are 50 Hz data codes.

11 . A non-transitory computer readable medium storing executable instructions that, when executed by an electronic device, cause the electronic device to:
receive an infrared carrier wave sent by an LED lamp and acquire GPS data codes from the infrared carrier wave; analyze the GPS data codes and obtain GPS data; determine a current position according to the GPS data; and plan a navigation route between the current position and a target position according to the current position.

12 . The non-transitory computer readable medium according to claim 11 , wherein, before receive an infrared carrier wave sent by an LED lamp and acquiring GPS data codes from the infrared carrier wave, the electronic device is further caused to:
modulate the GPS data codes onto the carrier wave through a code modulation technology, transmit the carrier wave modulated with GPS data codes through the infrared transmitter-receiver of the LED lamp, and generate the infrared carrier wave.

13 . The non-transitory computer readable medium according to claim 11 , wherein receive the infrared carrier wave sent by the LED lamp comprises:
receiving the infrared carrier wave at a frequency identical with the infrared carrier wave.

14 . The non-transitory computer readable medium according to claim 13 , wherein, the infrared carrier wave is a 38 KHz carrier wave.

15 . The non-transitory computer readable medium according to claim 11 , wherein, the GPS data codes are 50 Hz data codes.
