Abstract
A method for displaying point-of-interest coordinate locations in perspective images and for coordinate-based information transfer between perspective images on different platforms includes providing a shared reference image of a region overlapping the field of view of the perspective view. The perspective view is then correlated with the shared reference image so as to generate a mapping between the two views. This mapping is then used to derive a location of a given coordinate from the shared reference image within the perspective view and the location is indicated in the context of the perspective view on a display.
Claims22
A method for indicating, within a display of an arbitrary perspective view input from an imaging device, a location based upon a coordinate within a shared reference image, the method comprising:
- (a) providing a shared reference image of a region overlapping at least part of the field of view of the perspective view, the shared reference image having a defined coordinate system;
- (b) correlating the perspective view with the shared reference image so as to generate a mapping between said perspective view and said shared reference image;
- (c) employing said mapping to derive a location of a given coordinate of the shared reference image within the perspective view;
- and
- (d) indicating the location on said display.

A method for transferring information between two users viewing a common region of interest from different viewing directions, each user viewing the region of interest as a perspective view derived from an image sensor and presented on a display, the method comprising:
- (a) for each user:
- (i) providing a shared reference image of a region overlapping at least part of the field of view of the perspective view, the shared reference image having a defined coordinate system, and
- (ii) correlating the perspective view with the shared reference image so as to generate a mapping between said perspective view and said shared reference image;
- (b) inputting from the first user a location within the first user's perspective view designated as a point-of-interest location;
- (c) processing the input location, by use of the first user's mapping, to derive a coordinate in the shared reference image corresponding to the point-of-interest location;
- (d) processing the coordinate, by use of the second user's mapping, to derive a location of the coordinate within the second user's perspective view;
- and
- (e) indicating the point-of-interest location on the second user's display.
A system for indicating a location based upon a coordinate defined relative to a shared reference image, the system comprising:
- (a) an imaging sensor;
- (b) a display;
- (c) a display driver for receiving images from said image sensor and displaying said images on said display;
- (d) a data storage device for storing data corresponding to a shared reference image of a region at least partially overlapping a field of view of said image sensor, said shared reference image having a defined coordinate system;
- and
- (e) a processing system associated with said imaging sensor, said data storage device and said display driver, said processing system being configured for:
- (i) correlating a perspective view generated by said imaging sensor with said shared reference image so as to generate a mapping between said perspective view and said shared reference image;
- (ii) employing said mapping to derive a location of a given coordinate of said shared reference image within the perspective view;
- and
- (iii) actuating the display driver to indicate the location in the context of said images on said display.
