Abstract

A user equipment (UE) comprising a display, a visual input configured to capture motion or stop photography as visual data, a memory comprising instructions, and a processor coupled to the display, the input device, and the memory and configured to execute the instructions by receiving visual data from the visual input, determining a position of the feature relative to the UE if the visual data comprises a feature of a first area of a location, and generating a model of the first area of the location based on the position of the feature. The disclosure also includes a method comprising receiving data indicating a position of a feature of a location relative to a UE, and generating a model of the location based on the position of the feature.

Claims

1. A user equipment (UE) comprising:

a display;

a visual input configured to capture motion or stop photography as visual data;

a memory comprising instructions; and

a processor coupled to the display, the input device, and the memory and configured to execute the instructions by;

receiving visual data from the visual input;

determining a position of the feature relative to the UE if the visual data comprises a feature of a first area of a location; and

generating a model of the first area of the location based on the position of the feature.

2. The UE of claim 1, wherein the position of the feature relative to the UE is a function of a distance between the UE and the feature, wherein a distance between the UE and the feature is determined based on a height of the UE above a lower surface of the area and an angle α

, and wherein angle α

is an angle between a first line extending from the UE to the feature and second line extending between the UE and the feature in a lateral plane.

3. The UE of claim 2 further comprising a user input, wherein the height is received from a user via the user input.

4. The UE of claim 2 further comprising a position sensor coupled to the processor, wherein the height of the UE is determined based on data from the position sensor.

5. The UE of claim 2 further comprising a position sensor coupled to the processor, wherein the position sensor is configured to transmit field of view data to the processor, and wherein the processor is further configured to execute the instructions by determining the angle α

based on the field of view data.

6. The UE of claim 5, wherein the position sensor comprises a gyroscope or an accelerometer, and wherein the field of view data comprises an angle of a vertical facing of the UE measured by the gyroscope or accelerometer at a specified time.

7. The UE of claim 5 further comprising an input device coupled to the processor and configured to receive input from a user, wherein the processor is further configured to execute the instructions by determining the angle α

based on the field of view data received when the user input indicates that the visual data comprises the feature.

9. The UE of claim 1, wherein the position of the feature is determined based on a geographical facing of the UE at a specified time.

10. The UE of claim 9 further comprising a magnetometer coupled to the processor, wherein the geographical facing of the UE is determined based on data from the magnetometer.

11. The UE of claim 1, wherein the processor is further configured to execute the instructions by:

generating a model of a second area; and

generating a model of the location that comprises the model of the first area and the model of the second area.

12. The UE of claim 11, wherein the model of the location is generated by spatially connecting the model of the first area and the model of the second area.

13. The UE of claim 12 further comprising position sensors coupled to the processor, wherein the processor is further configured to execute the instructions by spatially connecting the model of the first area and the model of the second area based on position data received from the position sensors.

14. The UE of claim 13, wherein the position sensors comprise a global positioning system (GPS) sensor, and wherein the first area model and the second area model are spatially connected based on a global position of each area indicated by the GPS sensor.

15. The UE of claim 12, wherein the processor is further configured to execute the instructions by spatially connecting the model of the first area and the model of the second area based on user input.

16. A method comprising:

receiving data indicating a position of a feature of a location relative to a user equipment (UE); and

generating a model of the location based on the position of the feature.

17. The method of claim 16 further comprising:

receiving data indicating a height of the UE relative to a lower surface of the location; and

determining a scale of the model based on the height.

18. The method of claim 17, wherein the position of the feature relative to the UE is a function of a distance between the UE and the feature, wherein a distance between the UE and the feature is determined based on the height of the UE above a lower surface of the location and an angle α

, wherein the data indicating the position of a feature comprises the angle α

, and wherein the angle α

is an angle between a first line extending from the UE to the feature and second line extending between the UE and the feature in a lateral plane.

19. The method of claim 16, wherein the position of the feature is determined based on a geographical facing of the UE at a specified time.

20. The method of claim 16, wherein the position of the feature is determined based on a vertical facing of the UE at a specified time.
