Drinking bottle mouth vision positioning method

Abstract

The invention discloses a visual locating method of a beverage bottle jack. The invention has the procedure that: (1) an image is acquainted and pre-treated; (2) the coarse scanning and the fine scanning are performed to a bottle jack image after pre-treating and a centre of gravity method is adopted to obtain the reference coordinate point of a bottle jack circle center; (3) the edge point in the bottle jack image is found out through the reference coordinate point of the bottle jack circle center, and then the reference coordinate point of the bottle jack is located, a two-dimensional histogram H0 (Xr, Yr) collected by the circle centre coordinate is established, at last, the locating circle center calculation of a moving window is adopted to obtain a horizontal coordinate X0 and a longitudinal coordinate Y0 of the bottle jack circle centre. The invention is a visual locating method of the beverage bottle jack for realizing the automatic tracking and the quick and accurate location on a high speed automatic beverage filling production line, being used with an empty bottle detection equipment, a high speed filling equipment and automatic close over and packing equipments in a matched way, and greatly improving the automatic filling on the beverage production line, the detection sorting and the packing equipment automation level.

Description

Technical field [0001] The invention mainly relates to the field of visual positioning methods, in particular to a method for visual positioning of beverage bottle mouths on a high-speed beverage filling production line based on machine vision. Background technique [0002] In modern large-scale high-speed beverage filling production lines, the quality inspection, automatic filling and capping of empty bottles of beverages require precise positioning of the bottle mouth. However, the positioning device on the existing production line is mainly based on mechanical positioning, and its accuracy is low, and the positioning speed is slow, which cannot meet the requirements of modern high-speed automatic beverage filling production lines. The bottle mouth positioning method based on machine vision has the characteristics of high speed, high precision and high intelligence, which not only increases the flexibility and automation of production, but also greatly improves the intelligence...

AI Technical Summary

Problems solved by technology

In actual production, when the image of the bottle mouth is disturbed by factors such as external noise or there are large gaps and cracks in the image of the bottle mouth, there is a certain deviation in positioning, which seriously affects the production speed of the beverage filling line and reduces the qualification of the product.
