Mounted body design assistance device, mounted body design assistance method, and mounted body design assistance program

A mounted body design assistance method that assists in designing a mounted body to be mounted to a biological component surface, which is a surface of a part constituting a living body, the mounted body design assistance method including:

• receiving reference direction information representing a reference direction that is a direction of reference with respect to the biological component surface;
• receiving position information representing a position of a mounted body corresponding area, which is an area corresponding to the mounted body in a reference plane that is a plane perpendicular to the reference direction;
• acquiring projection position information representing projection positions, where sample positions in the mounted body corresponding area on the reference plane are projected onto the biological component surface in the reference direction, respectively, based on biological component surface shape information representing a three-dimensional shape of the biological component surface, the received reference direction information, and the received position information;
• acquiring smooth surface information representing a smooth surface that is a smooth curved surface defined by using the projection positions as control points based on the acquired projection position information;
• and
• generating mounted body shape information representing a three-dimensional shape of the mounted body so that the mounted body has at least a part of the smooth surface based on the acquired smooth surface information.

A non-transitory computer readable medium storing a mounted body design assistance program that causes a computer to execute a process for assisting in designing a mounted body to be mounted to a biological component surface, which is a surface of a part constituting a living body, the process including:

• receiving reference direction information representing a reference direction that is a direction being a reference with respect to the biological component surface;
• receiving position information representing a position of a mounted body corresponding area, which is an area corresponding to the mounted body in a reference plane that is a plane perpendicular to the reference direction;
• acquiring projection position information representing projection positions, where sample positions in the mounted body corresponding area on the reference plane are projected onto the biological component surface in the reference direction, respectively, based on biological component surface shape information representing a three-dimensional shape of the biological component surface, the received reference direction information, and the received position information;
• acquiring smooth surface information representing a smooth surface that is a smooth curved surface defined by using the projection positions as control points based on the acquired projection position information;
• and
• generating mounted body shape information representing a three-dimensional shape of the mounted body so that the mounted body has at least a part of the smooth surface based on the acquired smooth surface information.
