Abstract

The present invention relates to the technical field of computer vision and provides a surgical navigation system and an identification method thereof. The surgical navigation system comprises a visual marking base body and a visual navigator, and visual feature points are arranged in an outer side face of the visual marking base body in an axial direction and an circumferential direction of the visual marking base body; and the visual navigator is provided with an error control encoding module, and the visual mark base body is electrically connected with the error control encoding module. Thevisual feature points are equally arranged in the axial direction and the circumferential direction of the visual marking base body, the visual navigator detects space coordinates of the visual feature points in a visual field range of the visual navigator in real time, the error control coding module conducts error correction coding processing on the detected space coordinates, then an accuratespace position and a posture of the visual marking base body are recognized, and detection accuracy and reliability are improved.

Description

technical field [0001] The invention relates to the technical field of computer vision, in particular to an operation navigation system and an identification method thereof. Background technique [0002] With the development of computer technology, surgical navigation has brought revolutionary changes to surgical operations with its advantages of precision, flexibility, and minimal invasiveness, leading modern medicine from "intuitive medicine" to "precision medicine". Intraoperative guidance based on visual navigation technology can assist doctors to perform operations accurately according to predetermined surgical planning, and can minimize the risk of accidental damage to adjacent important anatomical structures. [0003] The key step of visual navigation technology is to accurately and reliably identify the spatial position and posture of visual markers. Generally, visual or electromagnetic navigation instruments are used as key detection components in surgical navigatio...
