Problems solved by technology

At present, the conventional measurement method is to use a projector. The measurer places each blade silk on the workpiece table of the projector, manually adjusts the screw rod of the workpiece table, and aligns the starting point and the end point of the blade wire respectively with the reference line of the measuring point, and then After the reading is completed, the measurement of one part of the shredded tobacco is completed. Each shredded tobacco needs to be measured at multiple points to calculate the average value. Due to the large number of shredded tobacco to be measured and the irregular shape, the surveyors are labor-intensive and slow, and the stability of the test results is poor.
Therefore, there is no daily detection and monitoring of the shred width in daily production

Embodiment Construction

[0024] figure 1 Among them, the lighting (optical) system mainly consists of LED light source, power supply and ellipsoidal mirror, which has the characteristics of large lighting area, high lighting intensity and good lighting uniformity, and is the basis for improving the imaging quality and measurement accuracy of leaf filaments. One of the keys of the present invention. There is an illumination system above the stage 1: the LED light source 2 is set at the focal point of the ellipsoidal mirror 3 (the LED light source is placed at the focal point of the ellipsoidal mirror, and the light emitted by the LED becomes quasi-parallel incident light through the ellipsoidal mirror, and the outgoing light A high-intensity and uniform lighting source is formed through the lighting optical system, which is the basis for improving the imaging quality and measurement accuracy of the leaf filament), and a parallel beam channel 4 and a half-mirror 5 are arranged in sequence in front of th...

Abstract

The invention relates to a rapid width measurement system for tobacco shreds, which is mainly composed of an image filtering and region segmentation unit, a subimage contour extraction unit and a single tobacco shred width calculation unit. By using the advanced computer technology, image recognition technology and real-time digital image processing technology, the invention can realize the rapidand accurate width measurement of a large number of tobacco shreds. By using the invention, multiple tobacco shreds can be measured in one step, and the average width and variability of each tobacco shred can be rapidly and accurately calculated. The invention has the characteristics of simplified equipment structure, accurate width measurement of tobacco shreds and high measurement efficiency.

Description

technical field [0001] The invention relates to a rapid measuring device and method for measuring the width of shredded leaves in the process of cutting shredded leaves in cigarette production, in particular to a method for measuring the width of shredded leaves through CCD (charge-coupled device image sensor) imaging technology, computer graphics processing technology and shredded shredded leaves. A rapid measuring method for the width of the shredded blade by the contour recognition measurement technology. Background technique [0002] The shredding process is an important process on the silk production line. Its main task is to cut the tobacco flakes with a suitable moisture content and temperature into shreds of a specified width, and minimize the breaking and "running of the flakes". The width of shredded leaf is the main quality index of the shredded process, and the width of shredded leaf has different influences on the physical index and sensory quality of cigarettes...
