Embodiment Construction

[0033] Embodiments of the present invention will be further described below in conjunction with accompanying drawings:

[0034] like figure 1 -Shown in 4, a kind of corrugated cardboard intelligent recognition algorithm based on image differential spatial frequency characteristics comprises the following steps:

[0035] Step 1, read the image: the line array camera acquires the image to be detected online, and sends the image to be detected to the computer, and the computer reads and calculates the image to be detected, and calculates the number of rows of the image to be detected as N x , the number of columns is N y ;

[0036] Step 2, capture the ROI in the image: set the width r of the ROI w , the spacing r of the ROI area p , the number of ROI regions r n , according to the three parameters selected by ROI, select r symmetrically with the center of the image n ROI;

[0037] Step 3, ROI image binarization: convert several ROIs into grayscale images to obtain ROI gray...

Abstract

The invention relates to a corrugated paper intelligent identification algorithm based on image difference spatial frequency characteristics. The method mainly solves the problems that by means of anexisting corrugated board counting method, false detection caused by paper board upwarp cannot be effectively recognized, and the algorithm complexity is high. The invention discloses a corrugated paper intelligent identification algorithm based on image difference spatial frequency characteristics. The algorithm comprises the following steps: step 1, reading an image; Step 2, intercepting an ROIin the image; Step 3, binarizing the ROI image; Step 4, ROI image corrosion; 5, binarizing the ROI corrosion image; Step 6, obtaining a differential image; 7, projecting the differential image; Step 8, acquiring a corrugated position; Step 9, periodic detection; And step 10, obtaining a counting result. The corrugated paper intelligent identification algorithm based on the image difference spatialfrequency characteristics can effectively identify false detection caused by upwarp of a paperboard; The algorithm is simple in step, low in calculation burden and capable of detecting the number ofcorrugated boards in real time.

Description

technical field [0001] The invention relates to the technical field of machine vision, in particular to an intelligent recognition algorithm for corrugated paper based on image differential spatial frequency characteristics. Background technique [0002] Corrugated cardboard is a multi-layer adhesive body, which consists of at least one layer of corrugated core paper interlayer (commonly known as "pit sheet", "corrugated paper", "corrugated core paper", "corrugated core", "corrugated base paper") and a layer Cardboard (also known as "boxboard", "boxboard"). It has good compressive strength and shockproof performance, and can withstand certain pressure, shock and vibration; it is light in weight, cheap in price, can be mass-produced in various sizes, has a small storage space before use, and can print various patterns, so in It is widely used in the packaging and transportation of finished products. [0003] Corrugated cardboard needs to be counted in mass production, but t...
