Aerial vehicle map determination
View Patent ↗A mapping system receives sensor data from an unmanned aerial vehicle. The mapping system further receives images from a camera of the unmanned aerial vehicle. The mapping system determines an altitude of the camera based on the sensor data. The mapping system calculates a footprint of the camera based on the altitude of the camera and a field of view of the camera. The mapping system constructs a localized map based on the images and the footprint of the camera.
1. A method comprising:
determining information associated with a camera of an aerial vehicle, the information including a length of a footprint of the camera and a width of the footprint of the camera, the length of the footprint being based on a horizontal component of a field of view (FOV) and an altitude of the camera and the width of the footprint being based on a vertical component of the field of view (FOV) and the altitude of the camera;
determining a localized map based on the information associated with the camera; and
overlaying the localized map on a vector map.
2. The method of claim 1 , wherein the vector map includes at least one of a road network, railroad network, airport, elevation contour, coastline, boundary, or index of geographical names.
3. The method of claim 1 , wherein determining information associated with the camera of the aerial vehicle comprises:
receiving sensor data from the aerial vehicle;
determining the altitude of the camera based on the sensor data;
determining the information associated with the camera based on the altitude of the camera and the FOV of the camera; and
determining the footprint of the camera based on the information associated with the camera.
4. The method of claim 3 , wherein determining the localized map based on the information associated with the camera comprises:
receiving images from the camera; and
determining the localized map based on the images and the footprint of the camera.
5. The method of claim 4 , further comprising:
de-warping the images.
6. The method of claim 5 , wherein de-warping the images comprises at least one of distortion correction or chromatic aberration correction.
7. The method of claim 4 , further comprising:
determining a position of the camera relative to an initial position of the camera, wherein the initial position is associated with the sensor data and the images.
8. The method of claim 3 , wherein the sensor data comprises any of global positioning system (GPS) data and barometric data.
9. A system comprising:
an aerial vehicle including a camera, a processor, and a memory, the memory including instructions that when executed cause the processor to:
determine information associated with the camera, the information including a length of a footprint of the camera and a width of the footprint of the camera, the length of the footprint being based on a horizontal component of a field of view (FOV) and an altitude of the camera and the width of the footprint being based on a vertical component of the field of view (FOV) and the altitude of the camera;
determine a localized map based on the information associated with the camera; and
overlay the localized map on a vector map, the vector map including geographical information.
10. The system of claim 9 , wherein the vector map further includes at least one of a road network, railroad network, airport, elevation contour, coastline, boundary, or index of geographical name.
11. The system of claim 9 , wherein to determine information associated with the camera of the aerial vehicle comprises to:
receive sensor data from the aerial vehicle;
determine the altitude of the camera based on the sensor data;
determine the information associated with the camera based on the altitude of the camera and the FOV of the camera; and
determine the footprint of the camera based on the information associated with the camera.
12. The system of claim 11 , wherein to determine the localized map based on the information associated with the camera comprises to:
receive images from the camera; and
determine the localized map based on the images and the footprint of the camera.
13. The system of claim 12 , further causing the processor to:
de-warp the images.
14. The system of claim 13 , wherein to de-warp the images comprises at least one of distortion correction or chromatic aberration correction.
15. The system of claim 12 , further causing the processor to:
determine a position of the camera relative to an initial position of the camera, wherein the initial position is associated with the sensor data and the images.
16. A non-transitory computer-readable storage medium comprising stored instructions that, when executed, causes at least one processor to:
determine information associated with a camera of an aerial vehicle, the information including a length of a footprint of the camera and a width of the footprint of the camera, the length of the footprint being based on a horizontal component of a field of view (FOV) and an altitude of the camera and the width of the footprint being based on a vertical component of the field of view (FOV) and the altitude of the camera;
determine a localized map based on the information associated with the camera; and
overlay the localized map on a vector map, the vector map including at least one of a road network, railroad network, airport, elevation contour, coastline, boundary, or index of geographical name.
