Hardware design and implementation of binocular vision system for a medical robot

In this paper, a hardware design method of binocular vision system is proposed for the pose tracker of surgery. The working principle of the system components and the needs of the surgical navigation are analyzed firstly. Then according to the situation of market supply, each component is ascertained, and the system's structure is affirmed based on the binocular vision positioning principle. At last, a simulation experiment of surgical navigation is developed by prototype of binocular vision system. The experimental results show that with the aid of this system, the layout of the surgery can be carried out. At the same time, the positioning precision for the implant can reach 2 mm, which can satisfy the requirement of clinical application.
