White granulated sugar bag automatic counting device and method based on machine vision

Abstract

The invention discloses a white granulated sugar bag automatic counting device and method based on machine vision. The device comprises a conveying belt frame body, a conveying belt, an equipment bracket, an industrial computer, a line laser fixing head, an industrial camera fixing head, a line laser and an industrial camera. The line laser and the industrial camera are installed on the equipmentsupport through the line laser fixing head and the industrial camera fixing head respectively. The method is used for laser contour generation and acquisition, an industrial computer slices a plurality of frames of white granulated sugar bags to segment the relative envelope area in a contour image, the number of the bags is calculated after comprehensive analysis, and the method comprises the steps of image preprocessing, laser stripe center line extraction, center line breakpoint compensation, relative envelope area calculation and bag number comprehensive calculation. Automatic counting inthe white granulated sugar bag conveying process is achieved, the problems that white granulated sugar bags are difficult to count in complex postures such as bag connection and bag stacking, and manpower consumption is large are effectively solved, the bag counting accuracy is effectively improved, and the labor cost of enterprises is reduced.

Description

technical field [0001] The invention belongs to the technical field of machine vision counting, and in particular relates to an automatic counting device and method for white sugar bags based on machine vision. Background technique [0002] White sugar is an important additive in the food processing industry, and it is also an indispensable condiment for home life. Most domestic white granulated sugar is packaged in 50Kg woven bags in the production area and distributed throughout the country. In grain depots, logistics centers, food processing plants and other storage, transshipment and processing points, the process of loading and unloading white sugar through conveyor belts involves the task of counting a large number of sugar bags. [0003] In the patent [CN201610813722.8], a counting and detection method for belt conveyors is proposed. In the patent [CN201710814559.1], a method for counting the number of packages of quantitative bag packaging materials is proposed. In ...
