Abstract
Official abstract text for this publication.
A navigation augmentation system includes a vehicle including an imaging device operably connected to a navigation data fusion module for receiving and analyzing visual point of interest data, gyroscope data, and accelerometer data, wherein the navigation data fusion module is operably connected to a sensor compensation module and an autopilot module for controlling the navigation of the vehicle.
First claim
Opening claim text (preview).
The invention claimed is: 1. A navigation augmentation system comprising: a vehicle including an imaging device comprising a plurality of cameras operably connected to a navigation data fusion module configured for receiving and analyzing visual point of interest data, gyroscope data, and accelerometer data; wherein the navigation data fusion module is operably connected to a sensor compensation module and an autopilot module for controlling the navigation of the vehicle, and the imaging device collects imaging data including a matrix of points, p in homogeneous coordinates: p = [ p 1 x p 2 x … p nx p 1 y p 2 y … p ny 1 1 … 1 ] where p nx is a pixel column of an n th point and p ny is a pixel row of the n th point and wherein a region of pixels around a point of interest of a first image and a second image includes: [ p x ′ p y ′ ] = argmax x , y ∑ R I ( p x , p y ) I ′ ( x , y ) where: p x ′ and p y ′ are corresponding column and row of point p in the second image, R is the region of pixels around p, I is the first image, and I′ is the second image. 2. The navigation augmentation system of claim 1 , wherein the accelerometer is operably connected to the sensor compensation module. 3. The navigation system of claim 1 , wherein the gyroscope is operably connected to the sensor compensation module. 4. The navigation system of claim 1 , wherein navigation data fusion module includes a Kalman filter. 5. The navigation system of claim 1 , wherein the imaging device includes a series of independent cameras. 6. The navigation system of claim 1 , wherein the imaging device includes a horizon sensor.
