Document Type and Number:
Japanese Patent JP6461257
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To highly accurately match positions of a three-dimensional image of a target object, and the target object itself or another image obtained by capturing the target object.SOLUTION: A medical image acquisition part 101 acquires a three-dimensional image obtained by imaging a target object by a first imaging device. A camera image acquisition part 104 acquires a two-dimensional image obtained by imaging a surface layer part of the target object by a second imaging device. A three-dimensional shape acquisition part 102 acquires information showing a surface position of the target object from the three-dimensional image. A virtual projection image generation part 107 generates a projection image obtained by viewing the three-dimensional image from the viewpoint of the second imaging device on the basis of the information showing the surface position. A positioning part 113 uses the projection image and the two-dimensional image to match positions of the three-dimensional image and the two-dimensional image with respect to the target object.SELECTED DRAWING: Figure 1
