IMAGE COMPLETION SYSTEM FOR IN-IMAGE CUTOFF REGION, IMAGE PROCESSING DEVICE, AND PROGRAM THEREFOR

摘要

An image completion system 10 includes an operating field endoscope 16 for obtaining an operating field image V1 in which an object space is imaged, a completing-purpose endoscope 17 for imaging the object space in a line-of-sight direction different from that of the operating field endoscope 16 to obtain a completing image V2 used for completing the operating field image V1, a distance measuring device 12 for measuring separating distances between a reference point and a large number of set points that are set in the object space, a three-dimensional position measuring device 13 for measuring three-dimensional positions of the endoscopes 16 and 17, and an image processing device 14 for obtaining, from the completing image V2, image information on cutoff regions in the object space that are hidden on the depth sides of surgical instruments S by imaging the surgical instruments S in the operating field image V1 together with the object space, on the basis of the measurement results, and for replacing image information on the surgical instruments S in the operating field image V1 with the obtained image information or superimposing the obtained image information onto the image information on the surgical instruments S in the operating field image V1.
