Embodiment Construction

[0063] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described with reference to the accompanying drawings.

[0064] see figure 1 , figure 1 A flowchart of an embodiment of the correction method provided by the present invention, figure 1 The correction method shown can be applied to a surgical navigation system, which includes a CCD, an endoscopic lens and a target marker, such as figure 1 As shown, the correction method includes the following steps:

[0065] Step S1. Obtain a first conversion relationship between the first coordinate system where the target marker is located and the second coordinate system where the endoscopic lens is located at an initial position.

[0066] In this embodiment, the CCD is a collection charge coupled device (Charge Coupled Device), which is an image sensor, and images can be acquired through the CCD...

Abstract

The invention provides a rectification method, a surgical navigation system, electronic equipment and a storage medium. The rectification method includes: acquiring first conversion relation between afirst coordinate system where a target marker is located and a second coordinate system where an endoscopic lens is located at the initial position; acquiring a rotation compensation matrix generatedby rotation of the endoscopic lens relative to a CCD (charge coupled device); on the basis of the first conversion relation and the rotation compensation matrix, determining second conversion relation between the first coordinate system and a third coordinate system where the endoscopic lens is located after rotation. By the arrangement, the conversion relation between the endoscopic lens and themarker is acquired in real time, accuracy of the conversion relation between the endoscopic lens and the marker can be improved, and safety in surgical navigation can be improved.

Description

technical field [0001] The invention relates to the field of surgical navigation, in particular to a correction method, a surgical navigation system, electronic equipment and a storage medium. Background technique [0002] With the rapid development of minimally invasive surgery and precision medicine, surgical navigation systems based on image processing have gradually become the mainstream of surgical operations. The surgical navigation system is mainly to connect the patient's preoperative medical image data with the specific position of the organ tissue during the operation through the computer, and combine it with the relevant surgical instruments, which can accurately display the three-dimensional space position of the organ tissue and the corresponding position. The spatial position relationship of important adjacent organizations. [0003] Existing endoscopic diagnosis and treatment is an important means of minimally invasive surgery, and the typical equipment that ...
