Abstract
A method and the device for acquiring and processing measurement quantities in a sewing machine (1) using at least one camera (25), situated on a sewing machine (1), for the acquisition and processing of image data for sewing machine elements and sewing elements. An image processing unit connected downstream from the camera (25) processes the images supplied by the camera (25), taking into account data stored in a target quantity memory, and influences the behavior of the machine control unit dependent on the result of the processing.
Claims20
A device for acquiring and processing measurement quantities in a sewing machine (1) before, during, or after the processing of an article being sewn (67), the sewing machine (1) comprising a machine control unit (47) for controlling a needle bar drive, at least one image capturing camera (25), and an image processing unit (43) connected to the camera (25), a target quantity memory (45) being allocated to the image processing unit (43), information concerning a plurality of sewing machine elements is stored in the target quantity memory (45) as target quantities and the image processing unit is configured to compare image data captured by the at least one camera to the information concerning the plurality of sewing machine elements stored in the target quantity memory and identifies a presence and a correct mounting of two or more of the sewing machine elements.
A method for obtaining and storing information concerning at least one feature of a plurality of sewing machine elements using a device for acquiring and processing measurement quantities in a sewing machine (1) before, during, or after the processing of an article being sewn (67), the sewing machine (1) comprising a machine control unit (47) for controlling a needle bar drive, at least one image capturing camera (25), an image processing unit (43) connected to the camera (25), a target quantity memory (45) allocated to the image processing unit (43), information concerning the at least one feature of the plurality of sewing machine elements is stored in the target quantity memory (45) as target quantities, the method comprising:
- storing information concerning the at least one feature of the plurality of sewing machine elements in the target quantity memory (45) as target quantities, and determining at least one of agreements or deviations between the target quantities stored in the target quantity memory (45) and image information supplied by the camera (25) for two or more of the sewing machine elements using the image processing unit (43) in order to determine a presence and a correct mounting of two or more of the sewing machine elements.
A method for obtaining and storing information concerning at least one feature of at least one sewing machine element using a device for acquiring and processing measurement quantities in a sewing machine (1) before, during, or after the processing of an article being sewn (67), the sewing machine (1) comprising a machine control unit (47) for controlling a needle bar drive, and comprising at least one image capturing camera (25) having a one- or two-dimensional array of light-sensitive pixels and an image processing unit (43) connected to the camera (25), a target quantity memory (45) being allocated to the image processing unit (43), information concerning at least one feature of at least one sewing machine element is stored in the target quantity memory (45) as a target quantity, the method comprising storing information concerning the at least one feature of the at least one sewing machine element in the target quantity memory (45) as a target quantity, and determining at least one of agreements or deviations between the target quantities stored in the target quantity memory (45) and image information supplied by the camera (25) in the image processing unit (43), information concerning at least one feature of at least one sewing element is stored in the target quantity memory (45) as a target quantity, and the image processing unit (43) determines the at least one of agreements or deviations between target quantities stored in the target quantity memory (45) and the image information supplied by the camera (25), and the image processing unit (43) determines information concerning at least one of brightness or contrast from images recorded by the camera (25), and the machine control unit (47) influences one or more light sources dependent on this information.
