Abstract

The invention is applicable to the technical field of visual positioning, and provides a metal component automatic positioning method and a terminal device. The automatic positioning method comprisesthe steps that an image of a metal component is acquired, and is binarized to acquire a binarized image; edge extraction is carried out on the binarized image to acquire an edge image; polygon fittingis carried out on the edge image, and the barycentric coordinate of the polygon is acquired according to the fitted polygon; and the center coordinate of the barycenter of all polygons and the slopeof a line fitted by the barycentric coordinates of all polygons are calculated according to the barycentric coordinate. According to the invention, some workpieces with high processing precision and fine workmanship are prevented from the risk of being scratched by a positioning device, and accurate and non-destructive positioning of processed workpieces is realized.

Description

technical field [0001] The invention belongs to the technical field of visual positioning, and in particular relates to an automatic positioning method for metal parts and a terminal device. Background technique [0002] With the rapid development of electronic science and technology, automated production has become a major trend in the electronic manufacturing industry. At present, in the process of automatic production and processing, the positioning of metal parts depends on mechanical positioning. [0003] The mechanical positioning method is mainly based on the principle of six-point positioning. Six supporting points are used to limit the six degrees of freedom of the workpiece. Keep it at an accurate processing position; this method of pressing and clamping the workpiece to achieve positioning is usually completed by the tightening device of the fixture. For some workpieces with high processing precision and fine workmanship, it is easy to damage and scratch the prod...
