Abstract
An image completion system includes a first endoscope for obtaining an operating field image, a second endoscope for imaging the object space in a line-of-sight direction different from that of the first endoscope to obtain a completing image, a first device for measuring separating distances between a reference point and a large number of set points that are set in the object space, a second device for measuring three-dimensional positions of the endoscopes, and an image processing device for obtaining, image information on cutoff regions in the object space that are hidden on the depth sides of surgical instruments by imaging the surgical instruments in the operating field image together with the object space, and for replacing image information on the surgical instruments S in the operating field image with the obtained image information or superimposing the obtained image information onto the image information on the surgical instruments.

8. An image completion system for an in-image cutoff region, comprising:
-
a main imaging device for obtaining a main image in which an object space to be monitored is imaged; a completing-purpose imaging device for obtaining a completing image used for completing the main image by imaging the object space in a line-of-sight direction different from that of the main imaging device; and an image processing device for completing a portion of the main image with the completing image on the basis of three-dimensional positions of set points which are set in the object space and three-dimensional positions of the main imaging device and the completing-purpose imaging device, wherein the main imaging device and the completing-purpose imaging device are provided so as to image the object space almost simultaneously, and the image processing device obtains, from the completing image, image information on a cutoff region in the object space that is hidden behind on a depth side of a member having a known shape by imaging the member in the main image together with the object space, on the basis of information on the three-dimensional positions that are continuously detected, and replaces image information on the member in the main image with the obtained image information or superimposes the obtained image information onto the image information on the member in the main image so as to generate a composite image in which the cutoff region is completed with the completing image. - View Dependent Claims (9, 10, 12, 13, 14)

11. An image processing device for performing a process to compose a main image of an object space to be monitored that is obtained by a main imaging device and a completing image of the object space that is imaged by a completing-purpose imaging device at the same time in a line-of-sight direction different from the main image so as to complete, when a member having a known shape is imaged in the main image together with the object space, image information on a cutoff region in the main image that is cut off by at least a portion of the member with image information on the completing image, the image processing device comprising:
-
set point position identifying means for identifying, with respect to set points which are set in the object space, sets of in-screen coordinates in a screen coordinate system of the main image and sets of in-screen coordinates in a screen coordinate system of the completing image, from three-dimensional positions of the set points and three-dimensional positions of the main imaging device and the completing-purpose imaging device; completing image transforming means for generating, on the basis of the sets of in-screen coordinates, a transformed image in which pieces of image information on points in the completing image are moved in a screen of the completing image such that the completing image is converted into that in a line-of-sight direction of the main image; cutoff region identifying means for identifying a position of the cutoff region in the main image; and composite image generating means for generating a composite image in which a cutoff region in the main image is completed with the completing image by replacing image information on the cutoff region with image information on a corresponding region that corresponds to the cutoff region in the transformed image or superimposing the image information on the corresponding region onto the image information on the cutoff region.
