Three-dimensional model generating system, three-dimensional model generating method, and program

A three-dimensional model generating system comprising at least one processor configured to:

• obtain a skeleton parameter, based on depth information of an object detected by a depth detecting device, which includes a depth sensor;
• change a posture of a three-dimensional model that is able to be deformed based on a body shape parameter, based on the skeleton parameter;
• obtain a surface shape of the object, based on the depth information;
• determine the body shape parameter, based on a difference between a surface shape of the three-dimensional model having the posture changed and the surface shape of the object;
• deform the three-dimensional model, based on the body shape parameter;
• specify a vertex corresponding to a detection range of the depth detecting device from the three-dimensional model, based on the depth information;
• and
• determine the body shape parameter, based on a difference between the surface shape of the three-dimensional model in the detection range and the surface shape of the object in the detection range.

A non-transitory computer-readable information storage medium having stored thereon a program for causing a computer to:

• obtain a skeleton parameter, based on depth information of an object detected by a depth detecting device, which includes a depth sensor;
• change a posture of a three-dimensional model that is able to be morphed based on a body shape parameter, based on the skeleton parameter;
• obtain a surface shape of the object, based on the depth information;
• determine the body shape parameter, based on a difference between a surface shape of the three-dimensional model having the posture changed and the surface shape of the object;
• deform the three-dimensional model, based on the body shape parameter;
• identify a body portion corresponding to a body of the object from among the three-dimensional model, based on the surface shape of the three-dimensional model or the object;
• and
• make larger a weight for a difference relevant to the body portion than a weight for a difference relevant to other portions when determining the body shape parameter.
