Title:
内視鏡用形状計測システムおよび内視鏡用形状計測方法
Document Type and Number:
Japanese Patent JP7462255
Kind Code:
B2
Abstract:
A display processing unit causes a display device to display an endoscopic image of a living tissue in a somatic cavity captured by an endoscope. An operation reception unit receives a user operation that is performed so as to set an area of interest in the endoscopic image. An area-of-interest setting unit sets the area of interest in the endoscopic image based on the user operation. A three-dimensional information acquisition unit acquires three-dimensional shape information of the living tissue captured by the endoscope. A virtual surface derivation unit derives three-dimensional shape information of a virtual surface in the area of interest from three-dimensional shape information of an area different from the area of interest. A size information identification unit identifies information concerning a size of the virtual surface from the three-dimensional shape information of the virtual surface.
