Abstract:
1. A sewing machine comprising: an image capturing device that is capable of capturing an image of a surface of a sewing target object held by an embroidery frame; a first reference setting portion that sets a reference relating to a first pattern as a first reference in accordance with an input command, the first pattern being a pattern that is sewn in a state in which a holding position of the sewing target object with respect to the embroidery frame is a first holding position and the first reference being used to determine, as a relative layout of a second pattern, at least one of a position and an angle of the second pattern with respect to at least one of a position and an angle of the first pattern, the second pattern being a pattern that is sewn in a state in which the holding position is a second holding position that is different from the first holding position; a first image data acquisition portion that acquires, as first image data, image data of an image including a marker that is arranged on the surface of the sewing target object, the image being captured by the image capturing device in the state in which the holding position is the first holding position; a first layout identification portion that, based on the first reference and the first image data, identifies, as a first marker layout, at least one of a position and an angle of the marker with respect to the first reference in the first holding position; a first reference change portion that, when a change command, which is a command to change the first reference, is input after the first marker layout is identified by the first layout identification portion, changes the first reference in accordance with the change command, and sets the changed first reference; a second layout identification portion that, when the changed first reference is set by the first reference change portion, identifies, as a second marker layout, at least one of a position and an angle of the marker with respect to the changed first reference in the first holding position, based on the changed first reference and the first marker layout; a second reference setting portion that sets, as a second reference, a reference relating to the second pattern that is used to determine the relative layout of the second pattern, in accordance with an input command; a layout determination portion that determines the relative layout of the second pattern based on one of the first reference and the changed first reference and on the second reference; a second image data acquisition portion that acquires, as second image data, image data of an image including the marker that is arranged on the surface of the sewing target object, the image being captured by the image capturing device in the state in which the holding position is the second holding position; a third layout identification portion that, based on one of the first marker layout and the second marker layout and on the second image data, identifies, as a third marker layout, at least one of a position and an angle of the marker with respect to one of the first reference in the second holding position and the changed first reference; and a setting portion that, based on the relative layout of the second pattern and on the third marker layout, sets at least one of a position and an angle of the second pattern with respect to the sewing target object in the second holding position.
