Abstract

A vision system which collects information from similar vision systems having a different perspective of a scene are arranged to produce a composite image. The composite image having information from both perspectives can then include features impossible to otherwise show. Objects otherwise “hidden” from a first perspective are displayed as information from a second perspective may contain imagery relating to those images. A translation of spatial coordinates conditions the image from the second perspective such that it will fit into a composite image and match the first perspective.

Claims

1. An apparatus for displaying composite images of a scene comprising a plurality of vision systems operable for addressing a common scene, each vision system being dynamic in position and attitude and independent of the position and attitude of each other system, the apparatus comprising at least two vision systems in communication with each other.

2. An apparatus of claim 1 at least one vision system comprising:

a position determining means;

an attitude determining means;

a computer;

a camera; and

a display,

said position determining means arranged to determine the position of the vision system camera;

said attitude determining means arranged to determine the pointing attitude of the camera;

said computer being coupled to each of the position determining means, attitude determining means, the camera, and the display.

3. An apparatus of claim 1 each vision system comprising:

a position determining means;

an attitude determining means;

a computer;

a camera; and

a display,

said position determining means arranged to determine the position of the vision system camera;

said attitude determining means arranged to determine the pointing attitude of the camera;

said computer being coupled to each of the position determining means, attitude determining means, the camera, and the display.

4. An apparatus of claim 2 at least two vision systems being electromagnetically coupled.

5. An apparatus of claim 3 at least two vision systems being electromagnetically coupled.

6. Methods of forming composite images with a plurality of vision systems each having a different perspective of a common scene, the method comprising the steps:

determine the position and attitude of each vision system;

form an image of the scene being addressed with each vision system;

transmit image information from a first vision system to a second vision system;

translate the perspective of the transmitted image to form an image having the perspective of the second vision system;

combine the image having a translated perspective with an image formed by the second vision system to form a composite image; and

present the composite image in the natural perspective of the second vision system.

7. Methods of claim 6 said ‘

form an image of the scene being addressed with each vision system’

step further comprising;

generate an image photonically

recall image data from a data store in accordance with position and attitude measurements; and

form graphical objects to be combined with images.

8. Methods of claim 6 said ‘

transmit image information from a first vision system to a second vision system’

step further comprising;

transmit an image formed by the first vision system

transmit the first vision system position and attitude information; and

transmit graphical objects formed at first vision system.

9. Methods of claim 6 said ‘

translate the perspective of the transmitted image to form an image having the perspective of the second vision system’

step further comprising;

translate perspective of the image information in accordance with the position and attitude of the first vision system; and

reform graphical objects in new perspective to appear normal to display field.
