10 . The height calculation system according to claim 4 ,
wherein the determination section corrects each value of the size associated with the height for each attribute based on the size of a part when a specific body part of a human of a person of which the height is known overlaps with the specific area.
11 . The height calculation system according to claim 5 ,
wherein the determination section corrects each value of the size associated with the height for each attribute based on the size of a part when a specific body part of a human of a person of which the height is known overlaps with the specific area.
12 . The height calculation system according to claim 6 ,
wherein the determination section corrects each value of the size associated with the height for each attribute based on the size of a part when a specific body part of a human of a person of which the height is known overlaps with the specific area.
13 . The height calculation system according to claim 7 ,
wherein the determination section corrects each value of the size associated with the height for each attribute based on the size of a part when a specific body part of a human of a person of which the height is known overlaps with the specific area.
14 . The height calculation system according to claim 8 ,
wherein the determination section corrects each value of the size associated with the height for each attribute based on the size of a part when a specific body part of a human of a person of which the height is known overlaps with the specific area.
15 . The height calculation system according to claim 1 ,
wherein the calculation section calculates the height of the person based on a relationship among the size of the part when the one part overlaps with the specific area, a first size that is associated with a first height and is smaller than the size of the part, and a second size that is larger than the size of the part and is associated with a second height which is larger than the first height.
16 . The height calculation system according to claim 9 ,
wherein the determination section determines each size to be associated with three or more predetermined heights by increasing the size to be associated as the height is increased, and
in calculation of the height of the person, the calculation section uses a next smaller size than the size of the one part and a next larger size than the size of the one part among the three or more sizes determined by the determination section.
17 . The height calculation system according to claim 10 ,
wherein the determination section determines each size to be associated with three or more predetermined heights by increasing the size to be associated as the height is increased, and
in calculation of the height of the person, the calculation section uses a next smaller size than the size of the one part and a next larger size than the size of the one part among the three or more sizes determined by the determination section.
18 . The height calculation system according to claim 11 ,
