Abstract

A three-dimensional data generating apparatus includes an input curve receiving unit configured to receive input of a curve indicating a relationship between a height and a distance from an outline of a target area to each position within the target area, a three-dimensional shape of the target area being generated from a two-dimensional image; and a three-dimensional data generating unit configured to calculate the height at each of the positions within the target area in accordance with the distance, the distance being calculated from a point on the outline to a corresponding position of the positions, and to generate data representing the three-dimensional shape of the target area based on the calculated height.

First claim

1 . A three-dimensional data generating apparatus comprising:
an input curve receiving unit configured to receive input of a curve indicating a relationship between a height and a distance from an outline of a target area to each of positions within the target area, a three-dimensional shape of the target area being generated from a two-dimensional image; and a three-dimensional data generating unit configured to calculate the height at each of the positions within the target area in accordance with the distance, the distance being calculated from a point on the outline to a corresponding position of the positions, and to generate data representing the three-dimensional shape of the target area based on the calculated height.

2 . The three-dimensional data generating apparatus according to claim 1 , wherein the point on the outline is a closest point on the outline to the corresponding position of the positions.

3 . The three-dimensional data generating apparatus according to claim 1 , wherein the point on the outline is a furthest point on the outline from the corresponding position of the positions.

4 . The three-dimensional data generating apparatus according to claim 1 , wherein a graph having a horizontal axis and a vertical axis is displayed, and a line that is drawn in the graph is obtained as the curve, one of the horizontal axis and the vertical axis representing the distance and another one of the horizontal axis and the vertical axis representing the height.

5 . The three-dimensional data generating apparatus according to claim 4 , wherein input of a maximum value on an axis that represents the distance in the graph is received, and a height at a point whose distance from the outline exceeds the maximum value within the target area is set to the maximum value on the axis.

6 . The three-dimensional data generating apparatus according to claim 4 , wherein distances from a plurality of points on the outline of the target area to each of the positions within the target area are calculated, and a maximum distance of the calculated distances is set to a maximum value on an axis that represents the distance in the graph.

7 . A non-transitory recording medium storing a program for causing a computer to execute a process comprising:
receiving input of a curve indicating a relationship between a height and a distance from an outline of a target area to each of positions within the target area, a three-dimensional shape of the target area being generated from a two-dimensional image; and calculating the height at each of the positions within the target area in accordance with the distance, the distance being calculated from a point on the outline to a corresponding position of the positions, and generating data representing the three-dimensional shape of the target area based on the calculated height.

8 . A three-dimensional data generating method comprising:
receiving input of a curve indicating a relationship between a height and a distance from an outline of a target area to each of positions within the target area, a three-dimensional shape of the target area being generated from a two-dimensional image; and calculating the height at each of the positions within the target area in accordance with the distance, the distance being calculated from a point on the outline to a corresponding position of the positions, and generating data representing the three-dimensional shape of the target area based on the calculated height.
