Abstract

Claims (29)

1. A system for displaying location or orientation-dependent images and information about an aircraft component, the system comprising:

a portable display;

at least one infrared marker, radio frequency emitter, or laser emitter fixed to the portable display;

at least one infrared marker, radio frequency emitter, or laser emitter fixed to the aircraft component;

at least one location and orientation-determining component comprising least one of an infrared camera, a radio frequency receiver, and a laser receiver and configured to detect locations of the infrared markers, radio frequency emitters, or laser emitters, and

a remote processor comprising a computing device and a memory storage device having a computer program executable by the computing device stored thereon, the computer program comprising:

a code segment for receiving a signal indicative of a location of a known point on the aircraft component and calibrating a coordinate origin to correspond with the location of the known point;

a code segment for receiving information from the location and orientation-determining component,

a code segment for determining a current location and orientation of the portable display relative to the coordinate origin based on the information received from the location and orientation-determining component; and

a code segment for outputting images to the portable display in realtime, wherein the images are views of a 3-dimensional model of the aircraft component rotated, zoomed, and panned based on the current location and orientation of the portable display relative to the coordinate origin.

2. The system of claim 1 , wherein the portable display does not comprise an image-capturing device.

3. The system of claim 1 , wherein the location and orientation components further comprise at least one of a geographic-location determining receiver, an accelerometer, tilt sensor, and inclinometer.

4. The system of claim 1 , wherein the information received from the location and orientation-determining component is filtered according to at least one of geographic location of the portable display and a user's security clearance received by at least one of the portable display and the remote processor.

5. A system for displaying location and orientation-dependent 3-dimensional model views, images, and information about an aircraft component, the system comprising:

a portable display having a plurality of infrared markers, radio frequency emitters, or laser emitters fixed thereto;

a plurality of location and orientation-determining components, wherein the location and orientation-determining components include at least one of an infrared camera, a radio frequency receiver, and a laser receiver configured to track locations of the plurality of infrared markers, radio frequency emitters, or laser emitters; and

a remote processor that:

receives signals output from the location and orientation-determining components,

determines locations of each of the infrared markers, radio frequency emitters, or laser emitters in a three-dimensional plane based on the signals received from the location and orientation-determining components,

determines a current orientation of the portable display using geometric equations based on the locations of each of the plurality of infrared markers, radio frequency emitters, or laser emitters in the three-dimensional plane, and

sends signals to the portable display in realtime, wherein the signals sent to the portable display comprise images to be displayed on the portable display, wherein the images are views of a 3-dimensional model of the aircraft component rotated, zoomed, and panned by the remote processor based on a current location and orientation of the portable display relative to a coordinate origin associated with a known point on the aircraft component.

6. The system of claim 5 , wherein the coordinate origin is associated with a coordinate origin of the 3-dimensional model of the aircraft component and the remote processor is calibrated to associate a determined location of the known point on the aircraft component with the coordinate origin.

7. A method for sending location and orientation-based image views and information about an aircraft component to a portable display, the method comprising:

receiving signals, with a remote processor, indicative of a location and orientation of the portable display from at least three infrared cameras collecting infrared data from at least three infrared markers fixed to the portable display;

determining, with the remote processor, a location and orientation of the portable display relative to a coordinate origin based on the signals received by the remote processor, wherein the remote processor is configured to associate the coordinates origin with a known point on the aircraft component; and

outputting, with the remote processor, images to the portable display in realtime, wherein the images are views of a 3-dimensional model of the aircraft component rotated, zoomed, and panned based on the location and orientation of the portable display relative to the coordinate origin.

8. The method of claim 7 , further comprising calibrating the coordinate origin to correspond to at least one of the infrared markers attached to the known point on the aircraft component.

9. The method of claim 7 , wherein the coordinate origin is the coordinate origin of the 3-dimensional model of the aircraft component.

10. The method of claim 7 , further comprising sending at least one of additional images, text, and data to the portable display filtered according to at least one of the location of the portable display, the orientation of the portable display, a particular task selected by a user of the portable display or the remote processor, and a security clearance of a user received by at least one of the portable display and the remote processor.
