Registration between medical images and physical space has been given more and more attention in the field of modern surgery research. It can help doctors to choose the best surgery path and reduce the surgery damage. And it can also improve the success rate of surgery and realize convenient operation and minimal invasiveness to surgery. In this paper, one key technology:the spatial registration technology based on iterative closest point in the surgical navigation systems. Obtain coordinate information, find out the optimal rotation matrix and the optimal translation vector. Obtain the results by the simulation experiments, and the results show that the ICP registration algorithm has the high accuracy, and excepted results are gotten.
