A sewing machine acquires embroidery data of an embroidery pattern including a first pattern to be sewn when a holding position of an embroidery frame is a first position and a second pattern to be sewn subsequent to the first pattern when the holding position is a second position. The sewing machine identifies an image capture area based on the embroidery data, and acquires first image data representing the image capture area and extracts a first feature point. And then, the sewing machine acquires second image data and extracts a second feature point. The sewing machine sets, based on the first feature point and the second image data, a layout of the second pattern with respect to the first pattern when the holding position is the second position and corrects the embroidery data. The sewing machine sews the second pattern on the sewing object based on the corrected embroidery data.

Computerized methods and software for creating customized embroidery. Embodiments include capturing a drawing from a user in a browser window as captured vectors, receiving the captured vectors and desired stitching parameters at an embroidery engine on a server, and creating a planned pattern of stitches from the captured vectors and the desired stitching parameters. Some embodiments include returning a rendering of the planned pattern of stitches to the browser or returning rendering vectors to the browser for drawing the planned pattern of stitches in the browser for inspection by the user. The drawing can include a freehand drawing, handwriting, or a signature, drawn or written by the user in the browser window. The desired stitching parameters can include angle, width, underlay type, density, or pull compensation of the stitches. In some embodiments, width varies along a vector path, for instance, based on pressure applied by the user while drawing.

An embroidery data generating apparatus includes: a coordinate position registration unit that registers coordinate positions of multiple track points detected at predetermined intervals from a track of a continuous line input via a screen, with them associated with a track point input order; a reference distance registration unit that registers a stitching pitch length as a reference distance; and an embroidery data generating unit configured to generate a desired track point on the continuous line as a needle location start point, to select particular track points that are subsequently input from among the multiple track points as reference track points, to convert the coordinate positions of the reference track points to arrange them in input order from the needle location start point at intervals of the reference distance, to generate the converted points as needle location points, and to generate data of the generated needle location points as embroidery data.

The sewing system includes a device and a sewing machine including a movement mechanism to move an embroidery frame. The device identifies reference point coordinates representing a position of a reference point provided in a range prescribed by an inner frame of the embroidery frame and transmits the reference point coordinates to the sewing machine. The sewing machine notifies a notification position, using a notification portion, with respect to the range prescribed by the inner frame and acquires a relative movement amount of the embroidery frame with respect to the notification portion, for aligning the notification position and the reference point provided in the range prescribed by the inner frame. The sewing machine decides, on the basis of a relationship between the movement amount and the reference point coordinates, a deviation from a prescribed state of a positional relationship between the inner frame and the movement mechanism.

A appliqu method includes: acquiring a first image of a first fabric piece; performing edge detection on the first image to acquire a plurality of edge points of the first fabric piece; calculating, for each of the edge points, coordinates of the edge point in a coordinate system corresponding to a computerized embroidery machine; and embroidering the first fabric piece onto a second fabric piece along an embroidering path formed by the coordinates of the edge points in the coordinate system.

Disclosed are various systems and features for use with a machine, such as a sewing machine, to facilitate multi-patch multi-view systems that may reduce errors associated with material thickness, object height, perspective. Such systems and features may be useful in the context of performing an action along a self-guided path on a substrate.
