Abstract

The invention discloses a cloth motion detection method and device, a sewing machine and computer equipment. The method comprises the steps: obtaining first compiled texture data of a cloth image, and converting the compiled texture data into a first matrix signal; after a first preset time period, obtaining second compiled texture data of the cloth image, and converting the second compiled texture data into a second matrix signal; comparing the first matrix signal with the second matrix signal, and obtaining a micro-motion distance of cloth in a feeding direction according to a comparison result; according to the micro-motion distance, calculating a real-time motion speed of the cloth; and according to the real-time motion speed and the current rotating speed of the sewing machine, calculating a current stitch length of the cloth, and thus accurately recognizing the motion direction and distance of the cloth. Therefore, the problem that stitch lengths are concentrated when the sewing machine is used for sewing the cloth is solved.

Description

technical field [0001] The present application relates to the technical field of sewing machines, in particular to a method and device for detecting cloth movement, a sewing machine and computer equipment. Background technique [0002] A sewing machine is a machine that uses one or more sewing threads to form one or more stitches on the sewing material to interweave or sew one or more layers of sewing material. In the related art, the sewing machine, as a fabric sewing machine, usually cannot sense the movement of the fabric. Generally, the operator judges the sewing movement of the fabric by hand-held and visual inspection. Since the manual cannot predict the situation in a short period of time, this judgment method has the advantages of Hysteresis, so there is no intelligent control of the fabric; at the same time, the actual thickness of the fabric being sewn is different, and the resistance generated during sewing is also different when the roughness is different. Theref...
