In order to solve the shortcomings of the current surgical navigation systems including weak anti-interference ability, complex system and non-multi-target tracking, an implement of surgical navigation system based on the detecting of artificial markers was proposed. Based on the Bumblebee2 binocular vision system, a detection algorithm based on edge detection was proposed to realize the precise and fast detection of ARTag artificial marks by line detection, marker construction and marker decode. Then with the Binocular stereo vision theory, accurately and reliably calculatedspatial location of the surgical instruments. Also, the system was able to tracking multiple targets in real-time because these artificial markers were set number sequences inside which enable the system to detect, decode and match multiple artificial marker targets. Experimental results showed that the proposed algorithm was of high accuracy and strong anti-interference ability, and the navigation system solution was fast, stable and economical, advantages multiple targets tracking at the same time, had broad prospects in actual use.
