Abstract

The present disclosure provides localization method and wearable device. The localization method is applicable to the wearable device, and includes: obtaining an environment information related to an environment where the wearable device is; determining a target map area in a map of the environment according to the environment information; and locating the wearable device in the map of the environment according to the target map area.

Claims (48)

1. A localization method applicable to a wearable device, and comprising:

obtaining an environment information related to an environment where the wearable device is;

determining a target map area in a map of the environment comprising a plurality of map areas according to the environment information, which comprises:

identifying one of the plurality of map areas based on the environment information; and

regarding others of the plurality of map areas as the target map area; and

locating the wearable device in the map of the environment by only using the target map area.

2. The localization method of claim 1 , wherein obtaining the environment information related to the environment where the wearable device is comprises:

by an image capturing circuit of the wearable device, scanning at least one two-dimensional code in the environment; and

by a processor of the wearable device, decoding the at least one two-dimensional code to obtain the environment information.

3. The localization method of claim 1 , wherein the environment information is prestored in a storage circuit of the wearable device, and obtaining the environment information related to the environment where the wearable device is comprises:

by a processor of the wearable device, accessing the environment information from the storage circuit.

4. The localization method of claim 1 , wherein obtaining the environment information related to the environment where the wearable device is comprises:

by a wireless communication circuit of the wearable device, establishing a wireless connection with at least one broadcast device;

by the wireless communication circuit, receiving at least one push signal transmitted by the at least one broadcast device through the wireless connection; and

by a processor of the wearable device, receiving the at least one push signal from the wireless communication circuit to obtain the environment information.

5. The localization method of claim 1 , wherein determining the target map area in the map of the environment according to the environment information comprises:

regarding the one of the plurality of map areas or others of the plurality of map areas as the target map area.

6. The localization method of claim 1 , wherein the environment information indicates that an environment area in the environment corresponding to the one of the plurality of map areas is provided with at least one reflective object.

7. The localization method of claim 1 , wherein when the environment information indicates that an environment area in the environment corresponding to one of the plurality of map areas in the map of the environment is a restricted area, the localization method further comprises:

generating a warning message corresponding to the one of the plurality of map areas in an immersive content.

8. The localization method of claim 1 , wherein before determining the target map area in the map of the environment according to the environment information, the localization method further comprises:

generating the map of the environment.

9. A wearable device, comprising:

an environment information collector, configured to collect an environment information related to an environment where the wearable device is; and

a processor, coupled to the environment information collector, configured to:

determine a target map area in a map of the environment comprising a plurality of map areas according to the environment information, which comprises: identifying one of the plurality of map areas based on the environment information, and regarding others of the plurality of map areas as the target map area; and

locate the wearable device in the map of the environment by only using the target map area.

10. The wearable device of claim 9 , wherein the environment information collector comprises:

an image capturing circuit, coupled to the processor, and configured to scan at least one two-dimensional code in the environment, wherein the at least one two-dimensional code records the environment information;

wherein the processor is configured to decode the at least one two-dimensional code to obtain the environment information.

11. The wearable device of claim 9 , wherein the environment information collector comprises:

a storage circuit, coupled to the processor, and configured to store the environment information;

wherein the processor is configured to access the environment information from the storage circuit.

12. The wearable device of claim 9 , wherein the environment information collector comprises:

a wireless communication circuit, coupled to the processor, configured to establish a wireless connection with at least one broadcast device, and configured to receive at least one push signal transmitted by the at least one broadcast device through the wireless connection, wherein the at least one push signal carries the environment information;

wherein the processor is configured to receive the at least one push signal from the wireless communication circuit to obtain the environment information.

13. The wearable device of claim 9 , wherein the processor is configured to regard the one of the plurality of map areas or others of the plurality of map areas as the target map area.

14. The wearable device of claim 9 , wherein the environment information indicates that an environment area in the environment corresponding to the one of the plurality of map areas is provided with at least one reflective object.

15. The wearable device of claim 9 , wherein when the environment information indicates that an environment area in the environment corresponding to one of the plurality of map areas in the map of the environment is a restricted area, the processor is configured to generate a warning message corresponding to the one of the plurality of map areas in an immersive content.

16. The wearable device of claim 15 , further comprising:

a display panel, coupled to the processor, wherein the processor is configured to control the display panel to display, so as to provide the immersive content.

17. The wearable device of claim 9 , wherein the processor is configured to generate the map of the environment before determining the target map area in the map of the environment.

18. A non-transitory computer readable storage medium with a computer program to execute a localization method applicable to a wearable device, wherein the localization method comprises:

obtaining an environment information related to an environment where the wearable device is;

determining a target map area in a map of the environment comprising a plurality of map areas according to the environment information, which comprises:

identifying one of the plurality of map areas based on the environment information; and

regarding others of the plurality of map areas as the target map area; and

locating the wearable device in the map of the environment by only using the target map area.
