Abstract
According to certain embodiments, an ophthalmic system for providing an image of an eye includes a camera system and a computer. The camera system includes stereoscopic cameras that provide image data for images of the eye. The computer: receives the image data from the camera system; accesses overlay data for an overlay for the image of the eye; aligns the overlay data and the image data; digitally combines the overlay data and the image data to yield combined image data for an image with the overlay; and provides the combined image data to a display device to display the image with the overlay in three dimensions.
Claims19
An ophthalmic system for providing an image of an eye, comprising:
- a camera system comprising a plurality of stereoscopic cameras configured to provide image data for one or more images of the eye, the stereoscopic cameras comprising a first camera and a second camera, the first camera configured to provide first image data for a first image, the second camera configured to provide second image data for a second image;
- and
- a computer configured to:
- receive the image data from the camera system;
- access overlay data for an overlay for the image of the eye, the overlay data comprising first overlay data and second overlay data;
- align the overlay data and the image data;
- digitally combine the overlay data and the image data to yield combined image data for an image with the overlay, the overlay data and the image data combined by digitally combining the first overlay data and the first image data and combining the second overlay data and the second image data;
- and
- provide the combined image data to a display device configured to display the image with the overlay in three dimensions.
An ophthalmic system for providing an image of an eye, comprising:
- a camera system comprising one or more cameras configured to provide image data for one or more images of the eye, each camera configured to provide the image data for an image of the one or more images of the eye;
- an eye tracker configured to determine a location of the eye according to the image data;
- and
- a computer configured to:
- receive the image data from the camera system;
- access overlay data for an overlay for the image of the eye;
- align the overlay data and the image data in accordance with the location of the eye;
- digitally combine the overlay data and the image data to yield combined image data for an image with the overlay;
- and
- provide the combined image data to a display device configured to display the image with the overlay.
