A appliqu&#xe9; 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.

Method of sewing a fabric piece onto another fabric piece based on image detection

A sewing machine includes a driving unit, a throat plate, a pressing unit, a detecting unit and a control unit. The detecting unit includes a housing mounted to a connecting module of the pressing unit, a track ball rotatably disposed on the housing, and adapted for contact with a fabric placed on the throat plate, and a plurality of Hall-effect sensors disposed in the housing such that, when the fabric is moved on the throat plate, the track ball rotates relative to the fabric and the housing, so that a rotational speed of the track ball is detected by the Hall-effect sensors. The control unit is disposed for controlling a moving speed of a needle bar of the driving unit corresponding to the rotational speed of the track ball.
