Abstract
A sewing machine includes a creating portion that creates a projection image being an image that includes a characteristic point and that is to be projected onto a sewing object, a projecting portion that projects onto the sewing object the projection image created by the creating portion, an image capture portion that is mounted in a position being different from a position of the projecting portion and that creates a captured image by image capture of the characteristic point projected by the projecting portion, and a computing portion that computes a thickness of the sewing object based on the projection image created by the creating portion and the captured image created by the image capture portion.
Claims4
A sewing machine, comprising:
- a creating portion that creates a projection image, the projection image including a characteristic point and being configured to be projected onto a sewing object;
- a projecting portion that is configured to project onto the sewing object the projection image created by the creating portion;
- an image capture portion that is mounted in a position being different from a position of the projecting portion and that is configured to create a captured image by image capture of the characteristic point projected by the projecting portion;
- and
- a computing portion that is configured to compute a thickness of the sewing object based on:
- (i) the projection image created by the creating portion, (ii) the captured image created by the image capture portion, (iii) an internal variable and an external variable for the projecting portion, and (iv) an internal variable and an external variable for the image capture portion.
A non-transitory computer-readable medium storing a control program executable on a sewing machine, the sewing machine comprising a projection portion and an image capture portion, the projection portion being configured to project a projection image onto a sewing object, the image capture portion being mounted in a position being different from a position of the projection portion and being configured to create a captured image by image capture, the program comprising instructions that cause a computer of the sewing machine to perform steps of:
- creating a projection image, the projection image including a characteristic point and being configured to be projected onto a sewing object;
- acquiring a captured image, the captured image being created by image capture of the characteristic point projected on the sewing object;
- and
- computing a thickness of the sewing object based on:
- (i) the projection image, (ii) the captured image, (iii) an internal variable and an external variable for the projection portion, and (iv) an internal variable and an external variable for the image capture portion.
