Three-dimensional localization of an arbitrary tool or the particles in flow in 3D scene is developed. It combines three arbitrarily localized cameras and system of calibration points. Least square data fitting is used to solve set of algebraic equations obtained for points localized at three planes of the cameras. At the present stage an accuracy below 1 mm is obtained for a typical 0.2 m3 3D scene. Quasi real-time (10 fps) data evaluation can be achieved using 32-bit frame grabber (AM-STD) and 450 MHz Pentium II processor. The primary application of the system is live tracking of a surgical tool within an operative field and displaying tool's position on a set of diagnostic tomographic images.
