US 9,434,181 B1 · Printing device and printing method

Abstract

A printing device includes a table that allows a plurality of printing subjects to be placed thereon, a projection device that projects a binary pattern to the printing subjects placed on the table, an image capturing device that captures an image of the printing subjects having the binary pattern projected thereon, a three-dimensional information acquirer that acquires a spatial code image from the image captured by the image capturing device and acquires three-dimensional information on the printing subjects from the acquired spatial code image, a recognizer that recognizes a position and a posture of each of the printing subjects from the acquired three-dimensional information, a disposer that disposes a printing image on each of the printing subjects in accordance with the position and posture thereof, and a printing data generator that generates printing data on the printing image disposed on each of the printing subjects.

Dependent claims

A printing device that acquires three-dimensional information on at least one printing subject having a three-dimensional shape and prints a predetermined printing image as a two-dimensional image on the at least one printing subject, the printing device comprising:

a table that allows the at least one printing subject to be placed thereon;
a projector that projects a predetermined pattern to the at least one printing subject placed on the table;
an image generator that captures an image of the at least one printing subject having the predetermined pattern projected thereon;
a three-dimensional information acquirer that acquires a spatial code image from the image captured by the image generator and acquires the three-dimensional information on the at least one printing subject from the acquired spatial code image;
a recognizer that recognizes a position and a posture of each of the at least one printing subject from the acquired three-dimensional information;
a disposer that disposes the printing image on each of the at least one printing subject in accordance with the position and the posture thereof;
and
a printing data generator that generates printing data representing the printing image disposed by the disposer.

A printing method by which three-dimensional information on at least one printing subject having a three-dimensional shape that is placed on a table is acquired, and a predetermined printing image as a two-dimensional image is printed on the at least one printing subject, the printing method comprising:

projecting a predetermined pattern onto the at least one printing subject placed on the table;
capturing an image of the at least one printing subject having the predetermined pattern projected thereon;
acquiring a spatial code image from the captured image, and acquiring the three-dimensional information on the at least one printing subject from the acquired spatial code image;
recognizing a position and a posture of each of the at least one printing subject from the acquired three-dimensional information;
disposing the printing image on each of the at least one printing subject in accordance with the position and the posture thereof;
and
generating printing data on the printing image disposed on the at least one printing subject.
