Virtual scale method and system of digital stereo-micrography system

Abstract

The invention provides a virtual scale method of a digital stereo-micrography system. The virtual scale method of the digital stereo-micrography system comprises obtaining a threshold interval of depth of field of a microscopy system; tracking a surgical instrument in a first path image of a three-dimension (3D) image by a tracking algorithm, and obtaining a surgical instrument area of the first path image; taking the surgical instrument area of the first path image as a template, judging similarity of a second path image, and obtaining a surgical instrument area of a second path image with the surgical instrument area of the second path image with the highest similarity; confirming optical parallax of the surgical instrument according to the surgical instrument area of the first path image and the second instrument area of the second path image, and then confirming the depth of the surgical instrument from a microscope objective lens; if the depth is in the threshold interval of depth of field, the depth is marked. The invention further provides a virtual scale system. The virtual scale system can accurately confirm the depth of the surgical instrument in the 3D image, and effectively improves safety and reliability of the surgery process.

Description

technical field [0001] The invention relates to the technical field of digital stereomicroscopic images, in particular to a virtual scale method for a digital stereoscopic microscope system and a virtual scale system for a digital stereoscopic microscope system. Background technique [0002] The current 3D digital microscope system installs a beam splitter on the traditional stereo microscope to split the optical signal collected by the microscope into two channels, and converts the optical signal split by the beam splitter into a digital signal through the CCD or CMOS photosensitive element on the industrial camera. Then the image data is transmitted to the computer or monitor through the data interface on the industrial camera, so that the observer can get rid of the shackles of the optical eyepiece. The 3D digital microscope system has two side-by-side imaging components. By collecting the observed objects in real time from different viewing angles, the binocular images o...

Problems solved by technology

[0003] Although the 3D digital microscope system can achieve 3D stereoscopic effects and provide high-definition three-dimensional space images, the traditional 3D digital microscope system cannot achieve accurate measurement of the relative position of objects in the 3D image

In the operation process, the depth of the position of the surgical instrument is very important, and the depth can only be perceived by the operator observing the 3D image through experience. Depth of surgical instruments in images, a technology that provides virtual rulers for digital stereo microscopy systems
