Abstract

An image processing apparatus includes a display unit that displays an image of a measurement object and an image of an object which corresponds to the measurement object and has a 3-dimensional (3D) shape which is calculated in advance, a designating unit that designates a first point on the image of the measurement object and a second point on the image of the object, a calculating unit that performs a geometric calculation of a first figure, an adjusting unit that adjusts a pose or a position of at least one of the image of the measurement object and the image of the object based on a result of the geometric calculation, and a measuring unit that calculates spatial coordinates on the object corresponding to a measurement position designated after the pose or the position is adjusted, and calculates a size of the object based on the calculated spatial coordinates.

Claims

1. An image processing apparatus, comprising:

a display unit that displays an image of a measurement object and an image of an object which corresponds to the measurement object and has a 3-dimensional (3D) shape which is calculated in advance;

a designating unit that designates a first point on the image of the measurement object and a second point on the image of the object based on an instruction input through an input device;

a calculating unit that performs a geometric calculation of a first figure based on the first point and a second figure based on the second point;

an adjusting unit that adjusts a pose or a position of at least one of the image of the measurement object and the image of the object based on a result of the geometric calculation; and

a measuring unit that calculates spatial coordinates on the object corresponding to a measurement position designated based on an instruction input through the input device after the pose or the position is adjusted, and calculates a size of the object based on the calculated spatial coordinates.

2. The image processing apparatus according to claim 1,

wherein each of the first point and the second point includes three or more points designated based on the instruction input through the input device.

3. The image processing apparatus according to claim 2,

wherein the calculating unit performs the geometric calculation such that the first point is associated with the second point based on an order in which the first point is designated and an order in which the second point is designated.

4. The image processing apparatus according to claim 1,

wherein the calculating unit performs a geometric calculation of a first figure on a plane based on the first point and a second figure on a space based on a point in a space of the object corresponding to the second point.

5. The image processing apparatus according to claim 4,

wherein the calculating unit performs a geometric calculation of the first figure on the plane and a third figure obtained such that the second figure in the space is projected onto the plane.

6. The image processing apparatus according to claim 1,

wherein the designating unit further sets a transparency of the image of the object when the first point is designated higher than a transparency of the image of the object when the second point is designated.

7. The image processing apparatus according to claim 1,

wherein the display unit maintains poses and positions of the image of the measurement object and the image of the object until the geometric calculation ends after displaying the image of the measurement object and the image of the object, and re-displays the image of the measurement object and the image of the object whose pose or position has been adjusted after the geometric calculation ends.

8. An image processing method, comprising:

a step of displaying an image of a measurement object and an image of an object which corresponds to the measurement object and has a 3-dimensional (3D) shape which is calculated in advance;

a step of designating a first point on the image of the measurement object and a second point on the image of the object based on an instruction input through an input device;

a step of performing a geometric calculation of a first figure based on the first point and a second figure based on the second point;

a step of adjusting a pose or a position of at least one of the image of the measurement object and the image of the object based on a result of the geometric calculation; and

a step of calculating spatial coordinates on the object corresponding to a measurement position designated based on an instruction input through the input device after the pose or the position is adjusted, and calculating a size of the object based on the calculated spatial coordinates.

9. The image processing method according to claim 8,

wherein each of the first point and the second point includes three or more points designated based on the instruction input through the input device, and

a calculating unit performs the geometric calculation such that the first point is associated with the second point based on an order in which the first point is designated and an order in which the second point is designated.

10. A computer program product having a program stored there in for causing a computer to function as:

a display unit that displays an image of a measurement object and an image of an object which corresponds to the measurement object and has a 3-dimensional (3D) shape which is calculated in advance;

a designating unit that designates a first point on the image of the measurement object and a second point on the image of the object based on an instruction input through an input device;

a calculating unit that performs a geometric calculation of a first figure based on the first point and a second figure based on the second point;

an adjusting unit that adjusts a pose or a position of at least one of the image of the measurement object and the image of the object based on a result of the geometric calculation; and

a measuring unit that calculates spatial coordinates on the object corresponding to a measurement position designated based on an instruction input through the input device after the pose or the position is adjusted, and calculates a size of the object based on the calculated spatial coordinates.
