1. A three-dimensional image display method, comprising:
a first acquisition step in which a processor connects to a recording medium storing first three-dimensional data of a subject and second three-dimensional data of the subject and acquires the first three-dimensional data from the recording medium,
wherein the first three-dimensional data include three-dimensional coordinates defined in a first three-dimensional coordinate system,
wherein the second three-dimensional data include three-dimensional coordinates defined in a second three-dimensional coordinate system different from the first three-dimensional coordinate system, and
wherein at least part of a region of the subject corresponding to the first three-dimensional data is different from at least part of a region of the subject corresponding to the second three-dimensional data;
a second acquisition step in which the processor connects to the recording medium and acquires the second three-dimensional data from the recording medium;
a conversion step in which the processor converts the first three-dimensional coordinate system and the second three-dimensional coordinate system into a three-dimensional common coordinate system on the basis of structure information related to a geometric structure of the subject,
wherein the structure information is generated without using the first three-dimensional data or the second three-dimensional data; and
a display step in which the processor displays an image of the first three-dimensional data in the common coordinate system and an image of the second three-dimensional data in the common coordinate system on a display.
