From the application point of view, car navigation systems can be divided into two categories.

从应用的角度，汽车导航系统可分为两类。

The system gets two image of one object with two CCD, thus obtains depth from two CCD"s parallax. After investigating the operation spot and discussing with surgeons we use LED as markers, and get the marker"s 3-D position with a non-contact optics orientation method. After calibrating the CCD, processing the image, the system can figure out marker"s areal coordinates, get marker"s 3-D coordinate in dummy world coordinate system, thereby obtain instruments 3-D position and orientation. After the coordinate transformation and a series of orientation calculation, operation navigation comes true.
