An Electrode Guidance Navigation based on Markerless Augmented Reality

The electrode guidance navigation is composed of two key parts: preparation part and navigation part. The preparation part is initial setup process to save the reference electrode position and facial surface. In the navigation part, the result of real-time surface registration between reference and current scanning data is visualized for electrode guidance.

In the system, ICP based surface registration between reference facial surface and real-time scanning data is repeatedly processed.

By applying the transformation, the reference data is transformed to the coordinate system of current scanning data, ?_??? on the basis of facial surface.

The result of real-time surface registration shows AR data which overlay reference electrode position on real-time scanning data. Therefore, the system enable to place the current electrode with respect to saved reference position.
