Abstract

The invention relates to an endoscope calibration system and method. The endoscope calibration system includes an endoscope module, a calibration target module, and an optical tracking module, wherein the endoscope module includes a front end of the endoscope module, and an endoscope camera located in an endoscope camera channel; the calibration target module is a calibration plate such as a flat plate with an equally-spaced solid circle array pattern or a flat plate with a checkerboard pattern; the optical tracking module includes an optical tracker positioned at the front end of the endoscope, an optical tracker attached to a calibration target, and an optical position sensor. The invention also relates to an endoscope calibration method. According to the invention, the endoscope calibration can be carried out effectively, conveniently and accurately, and the working channels of the endoscope cannot be occupied additionally. The endoscope calibration system and method can be used for the real-time surgical navigation.

Description

technical field [0001] The invention relates to an endoscope calibration system and method. Background technique [0002] Minimally invasive surgery (Minimally Invasive Surgery, MIS) is one of the main development trends in clinical medicine, and Image-Guided Surgery (IGS) technology is a vital part of the rapidly developing minimally invasive surgery technology. Image-guided surgery technology uses a variety of medical equipment to formulate effective surgical treatment plans and realize surgical navigation during surgery, thereby reducing surgical treatment risks and improving treatment accuracy. At the same time, with the emergence of more and more diversified medical equipment such as endoscopes, ultrasound, computed tomography, and magnetic resonance, medical imaging of different modalities can be realized, thus enabling multimodal image-guided surgery (Multimodal Image-GuideSurgery) , MIS) has been greatly developed and has become one of the hotspots in the field of i...
