Design considerations for a computer-vision-enabled ophthalmic augmented reality environment

We have initiated studies towards the design and implementation of an ophthalmic augmented reality environment in order to allow for a more precise laser treatment for ophthalmic diseases, b teaching, c telemedicine, and d real-time image measurement, analysis, and comparison. The proposed system is being designed around a standard slitlamp biomicroscope. The microscope will be interfaced to a CCD camera, and the image sent to a video capture board. A single computer workstation will coordinate image capture, registration, and display. The captured image is registered with previously stored, montaged photographic and angiographic data, with superposition facilitated by funduslandmark-based fast registration algorithms. The computer then drives a high intensity, VGA resolution video display with adjustable brightness and contrast attached to one of the oculars of the slitlamp biomicroscope. Preliminary studies with a modi ed binocular operating microscope interfaced to a Sun Ultra1...
