Abstract
A simulator (1) has a body form apparatus (2) with a skin-like panel (4) through which laproscopic instruments (5) are inserted. Cameras (10) capture video images of internal movement of the instruments (5) and a computer (6) processes them. 3D positional data is generated using stereo triangulation and is linked with the associated video images. A graphics engine (60) uses the 3D data to generate graphical representations of internal scenes. A blending function (70) blends real and recorded images, or real and simulated images to allow demonstration of effects such as internal bleeding or suturing.
