Merging virtual objects with the real world
Michael Bajura, Henry Fuchs, Ryutarou Ohbuchi · 1992
We describe initial results which show "live" ultrasound echography data visualized within a pregnant human subject.The visualization is achieved by using a small video camera mounted in front of a conventional head-mounted display worn by an observer.The camera's video images are composite with computer-generated ones that contain one or more 2D ultrasound images properly transformed to the observer's current viewing position.As the observer walks around the subject.the ultrasound images appear stationary in 3-space within the subject.This kind of enhancement of the observer's vision may have many other applications, e.g., image guided surgical procedures and on location 3D interactive architecture preview.
