Abstract

The invention provides a visual positioning method and system for sewing. An image of a cloth material to be sewn is obtained by shooting and processing an image of a sewing workbench, a datum point is preset on the sewing workbench, and centroid coordinates, sewing starting point coordinates and the current sewing direction of the cloth material to be sewn are obtained in the image of the cloth material to be sewn with the image of the sewing workbench as a coordinate plane; true position coordinates of the datum point in the coordinate plane are obtained with the sewing workbench as a true position coordinate plane, and the centroid coordinates and the sewing starting point coordinates in the image of the sewing workbench are converted into true position coordinates of the sewing workbench; the cloth material to be sewn is rotated to the current sewing direction parallel to the preset sewing direction with true position coordinates of the centroid as the rotating center; the moving distance between the sewing starting point and the datum point is calculated, and the cloth material to be sewn is moved to the sewing starting point corresponding to the datum point for sewing work according to the moving distance. Since visual image processing is used for positioning, the problem that existing automatic sewing is poor in positioning is well solved.

Description

technical field [0001] The invention relates to the technical field of sewing, in particular to a visual positioning method and system for sewing. Background technique [0002] At present, in automatic sewing, templates are used for sewing, and sensors are used to position the template, which can only be used for sewing a single piece of cloth. If the template is changed, the design of the sensor or mechanical device needs to be changed accordingly, which is not conducive to Adjustment. And using a sensor, there may be a problem of low accuracy. Contents of the invention [0003] In view of the shortcomings of the prior art described above, the purpose of the present invention is to provide a visual positioning method and system for sewing to solve the problem of poor positioning in existing automatic sewing. [0004] In order to achieve the above and other related goals, the present invention provides a visual positioning method for sewing, including: taking an image of...
