Problems solved by technology

However, since it is difficult to obtain a sense of perspective from 2D images, and the relative distance between the surgical site and the treatment tool may be difficult to grasp, in recent years, a technique of displaying captured images of the surgical site as stereoscopic three-dimensional (3D) images has also been developed

Abstract

To further reduce the load relating to the correction of distortion in an observation image, attributable to an error among a plurality of imagers. Provided is a stereoscopic observation device for medical use, including: an obtaining unit that obtains correction data from an imaging unit including a first imager that captures an image for a left eye and a second imager that captures an image fora right eye and rotatably held by a support, the correction data serving to correct an imaging error in the images between the first imager and the second imager; and a correcting unit that corrects aparallax shift between the image for the left eye and the image for the right eye on the basis of the correction data with a position corresponding to a rotation axis of the imaging unit serving as areference position.

Description

technical field [0001] The present disclosure relates to a medical stereoscopic observation device, a medical stereoscopic observation method and a program. Background technique [0002] Recently, due to advances in surgical techniques and surgical equipment, surgery is often performed for performing various treatments while observing a surgical site with a medical observation device such as an operating microscope or endoscope (also called microsurgery). In addition, such medical observation devices are not limited to those capable of optically observing the surgical site, but also include devices that display images of the surgical site captured by an imaging section (camera) or the like as electronic images on a display such as a monitor. [0003] Furthermore, when an image of an operation site captured by an imaging section of an observation device is displayed on a display, the image is often displayed as a flat two-dimensional (2D) image. However, since it is difficul...
