Moreover, in Japanese Patent No. 5354494, an algorithm for generating a 3D shape image from a 2D image is proposed, but there is no disclosure or suggestion on how to display the generated 3D shape image
That is, according to Japanese Patent No. 5354494, there is a lack of a function of displaying a 3D shape image in such a way that the user can easily observe it

[0070] figure 1 The shown endoscope system 1 has: an endoscope 2A, which is inserted into a subject; a light source device 3, which supplies illumination light to the endoscope 2A; and a video processor 4 as a signal processing device, which performs The signal processing of the imaging unit provided in the endoscope 2A; the monitor 5 as an endoscope image display device that displays the endoscope image generated by the video processor 4; the UPD device as an insertion part shape detection device 6. It detects the shape of the insertion portion of the endoscope 2A from a sensor provided in the endoscope 2A; an image processing device 7 performs image processing for generating a 3D (also referred to as 3D) model image from a 2D image and a monitor 8 as a display device for displaying the 3D model image generated by the image processing device 7 . Alternatively, instead of figure 1 The image processing device 7 shown by the solid line is separate from the UPD device 6 , and a...

An endoscope system according to the present invention has: an insertion unit for radiating illumination light, the insertion unit being inserted in a subject having a three-dimensional shape; an imaging unit for receiving return light from a region inside the subject irradiated by the illumination light from the insertion unit and sequentially generating imaging signals; and an image processing unit for generating three-dimensional data indicating the shape of a first region when a first imaging signal generated when return light from the first region is received is inputted, and generating three-dimensional data indicating the shape of a second region when a second imaging signal is inputted which is generated when return light from the second region is received after reception of returnlight from the first region, and generating a three-dimensional image on the basis of the three-dimensional data indicating the shape of the first and second regions and outputting the three-dimensional image to a display unit.
Description
technical field [0001] The present invention relates to an endoscope system and an image processing method for observing a subject using an endoscope. Background technique [0002] In recent years, endoscope systems using endoscopes have been widely used in the medical and industrial fields. For example, in the medical field, it is sometimes necessary to insert an endoscope into an organ having a complicated lumen shape in a subject to observe or inspect the interior of the organ in detail. [0003] For example, in the conventional example of Japanese Patent No. 5354494, the following endoscope system is proposed: in order to present the area observed by the endoscope, an internal view of an organ is generated from an endoscope image captured by the endoscope. cavity shape and display it. [0004] In this way, since the image acquired by the endoscope is a 2D image, it is necessary to generate a 3D shape image from the 2D image. Furthermore, Japanese Patent No. 5354494 pr...
