Abstract

Systems and methods to generate maps or models of structures are disclosed. Features of the structure to be mapped may be determined for the purposes of generating the map or model based at least in part on images associated with the structure, sensor measurements associated with the structure, and phase data of communications signals that interact with the structure. The mapping or modeling processes may be performed at a mapping server that receives images, sensor data, and/or communications signal phase information from one or more user devices, such as mobile devices. The mapping servers may perform a simultaneous localization and mapping (SLAM) process and may enhance the generated maps using sensor and/or communications phase data to map one or more hidden features of the structure.

Claims

1. A method, comprising:

receiving, by a mapping server comprising one or more processors, a plurality of images from at least one user device;

analyzing, by the mapping server, the plurality of images;

determining, by the mapping server and based at least in part on the analyzing, that the images are associated with a structure; and

generating, by the mapping server, a map of the structure based at least in part on the plurality of images.

2. The method of claim 1, wherein the plurality of images include image information of at least one feature of the structure.

3. The method of claim 2, wherein analyzing the plurality of images comprises identifying the at least one feature of the structure in the each of the plurality of images.

4. The method of claim 1, wherein the generating the map of the structure comprises:

manipulating, by the mapping servers, each of the plurality of images to generate a plurality of manipulated images; and

combining, by the mapping servers, the manipulated images.

5. The method of claim 1, further comprising:

receiving, by the mapping servers, communications phase information;

determining, by the mapping servers, a location of at least one hidden feature associated with the structure based at least in part on the communications phase information; and

updating, by the mapping servers, the map based at least in part on the location of the at least one hidden feature.

6. The method of claim 7, wherein the at least one hidden feature includes a feature behind a wall of the structure.

7. The method of claim 1, further comprising:

receiving, by the mapping servers, one or more sensor information associated with the structure; and

updating, by the mapping server, the map based at least in part on the one or more sensor information.

8. The method of claim 1, wherein the map comprises at least one of:

(i) a layout of the structure;

(ii) a profile of the structure;

or (iii) a cross-section of the structure.

9. One or more computer-readable media comprising computer-executable instructions that, when executed by one or more processors, configure the one or more processors to perform a method comprising:

receiving a plurality of images from a plurality of user devices;

analyzing the plurality of images;

determining, based at least in part on the analyzing, that the images are associated with a structure; and

generating a map of the structure based at least in part on the plurality of images.

10. The one or more computer-readable media of claim 9, wherein the plurality of images include image information of at least one feature of the structure.

11. The one or more computer-readable media of claim 9, wherein analyzing the plurality of images comprises identifying the at least one feature of the structure in the each of the plurality of images.

12. The one or more computer-readable media of claim 9, wherein the generating the map of the structure comprises:

manipulating each of the plurality of images to generate a plurality of manipulated images; and

combining the manipulated images.

13. The one or more computer-readable media of claim 9, wherein the method further comprises:

receiving communications phase information;

determining a location of at least one hidden feature associated with the structure based at least in part on the communications phase information; and

updating the map based at least in part on the location of the at least one hidden feature.

14. The one or more computer-readable media of claim 13, wherein the at least one hidden feature includes a feature behind a wall of the structure.

15. The one or more computer-readable media of claim 9, wherein the method further comprises:

receiving one or more sensor information associated with the structure; and

updating the map based at least in part on the one or more sensor information.

16. The one or more computer-readable media of claim 9, wherein the map comprises at least one of:

(i) a layout of the structure;

(ii) a profile of the structure;

or (iii) a cross-section of the structure.

17. A system, comprising:

at least one memory that stores computer-executable instructions;

at least one processor configured to access the at least one memory, wherein the at least one processor is configured to execute the computer-executable instructions to;

receive a plurality of images from a plurality of user devices;

analyze the plurality of images;

determine, based at least in part on the analyzing, that the images are associated with a structure; and

generate a map of the structure based at least in part on the plurality of images.

18. The system of claim 17, wherein the plurality of images include image information of at least one feature of the structure.

19. The system of claim 17, wherein the at least one processor is configured to execute the computer-executable instructions to analyze the plurality of images comprises the at least one processor is configured to execute the computer-executable instructions to identify the at least one feature of the structure in the each of the plurality of images.

20. The system of claim 17, wherein the at least one processor is configured to execute the computer-executable instructions to generate the map of the structure comprises the at least one processor is configured to execute the computer-executable instructions to:
