Abstract

An information processing apparatus includes: an acquisition portion that acquires position/direction information indicative of a position and a direction of a projection device; a selection portion that selects at least one piece of drawing data from a plurality of pieces of drawing data relating to parts provided in an object; a generation portion that generates a projection drawing from the drawing data selected by the selection portion; a conversion portion that calculates a distance between the object and the projection device, and a direction of the projection device from the position/direction information, and converts the projection drawing into a perspective drawing by using the calculated distance and the calculated direction; and a control portion that controls the projection device so as to project the perspective drawing onto the object.

Claims

1. An information processing apparatus comprising:

an acquisition portion that acquires position/direction information indicative of a position and a direction of a projection device;

a selection portion that selects at least one piece of drawing data from a plurality of pieces of drawing data relating to parts provided in an object;

a generation portion that generates a projection drawing from the drawing data selected by the selection portion;

a conversion portion that calculates a distance between the object and the projection device, and a direction of the projection device from the position/direction information, and converts the projection drawing into a perspective drawing by using the calculated distance and the calculated direction; and

a control portion that controls the projection device so as to project the perspective drawing onto the object.

2. The information processing apparatus according to claim 1, wherein

the acquisition portion acquires the position/direction information after the movement of the projection device from a movement device moving the projection device, and

the conversion portion calculates the distance between the object and the projection device, and the direction of the projection device from the position/direction information after the movement of the projection device, and converts the projection drawing into the perspective drawing by using the calculated distance and the calculated direction.

3. The information processing apparatus according to claim 1, further comprising a detection portion that detects an indication position on the object by a user from a capture image of the object, wherein

the generation portion generates the projection drawing from the drawing data relating to a part corresponding to the indication position, and

the control portion controls the projection device so as to highlight the perspective drawing when the perspective drawing is projected onto the object.

4. The information processing apparatus according to claim 3, wherein the detection portion acquires the indication position on the object by the user from an external device connected to the information processing apparatus.

5. The information processing apparatus according to claim 1, further comprising a detection portion that detects an indication position on the object by a user from a capture image of the object, wherein

the generation portion generates a cross-section drawing when the object is cut in a plane passing the indication position, based on the drawing data relating to a part corresponding to the indication position,

the conversion portion calculates the distance between the object and the projection device, and the direction of the projection device from the position/direction information, and converts the cross-section drawing into the perspective drawing by using the calculated distance and the calculated direction, and

the control portion controls the projection device so as to project the perspective drawing onto an outer bailey of the object in parallel with or in substantially parallel with the plane passing the indication position.

6. The information processing apparatus according to claim 5, wherein the control portion controls the projection device so as to project the perspective drawing and an image corresponding to a cut edge of the indication position onto an outer bailey of the object in parallel with or in substantially parallel with the plane passing the indication position.

7. The information processing apparatus according to claim 5, wherein the detection portion acquires the indication position on the object by the user from an external device connected to the information processing apparatus.

8. An image processing system comprising:

a second information processing apparatus that selects at least one of piece of drawing data from a plurality of pieces of drawing data relating to parts provided in an object, and notifies a first information processing apparatus of information indicative of the selected drawing data; and

the first information processing apparatus including;

an acquisition portion that acquires position/direction information indicative of a position and a direction of a projection device;

a generation portion that generates a projection drawing from the drawing data corresponding to the information notified from the second information processing apparatus;

a conversion portion that calculates a distance between the object and the projection device, and a direction of the projection device from the position/direction information, and converts the projection drawing into a perspective drawing by using the calculated distance and the calculated direction; and

a control portion that controls the projection device so as to project the perspective drawing onto the object.

9. A computer readable medium causing a computer to execute a process, the process comprising:

acquiring position/direction information indicative of a position and a direction of a projection device;

selecting at least one piece of drawing data from a plurality of pieces of drawing data relating to parts provided in an object;

generating a projection drawing from the selected drawing data;

calculating a distance between the object and the projection device, and a direction of the projection device from the position/direction information;

converting the projection drawing into a perspective drawing by using the calculated distance and the calculated direction; and

controlling the projection device so as to project the perspective drawing onto the object.
