Sewing machine, and computer-readable storage medium storing sewing machine control program |
摘要 |
A sewing machine includes an image pickup device that picks up over a sewing machine bed; a feature point coordinates calculation device that extracts feature points from the picked up image and calculates two-dimensional coordinates of the feature points; a reference coordinates storage device that stores three-dimensional reference coordinates of the feature points; a correlation device that correlates the reference coordinates with the feature point coordinates; a parameter calculation device that calculates a parameter about the image pickup device; a parameter storage device that stores the calculated parameter; a comparison image acquisition device that acquires the picked up image as a comparison image; a first determination device that determines whether comparison information matches with parameter information; and a first notification device that notifies that it is necessary to re-calculate the parameter depending on the result by the first determination device. |
