Problems solved by technology

[0005] At present, the conventional measurement method is to use a projector, and the worker measures root by root. In this method, the number of leaves to be measured is large and the shape is irregular. For the measurer, the labor intensity is high, the speed is slow, and the stability of the test results is poor.

Embodiment Construction

[0030] Such as figure 1 As shown, the filament width measuring device of the present invention includes five parts: an imaging system 101 , an illumination system 102 , a workpiece platform system 103 , a control system 104 and a computer 105 . The lighting system 102 projects the line light source on the filament carrying box 305 of the workpiece platform system 103, and the filament carrying box 305 is driven to reciprocate by the transmission motor 303 on the workpiece platform system 103. At this time, the imaging system 101 collects images with a certain step The shredded leaf image will be merged into a two-dimensional shredded leaf image after scanning. The acquisition of the entire image is completed by the communication between the computer 105 and the control system 104 , and the finally acquired image is calculated by the computer 105 to obtain the result.

[0031] The imaging system 101 includes a linear array CCD camera 201 and a CCD lens 202; wherein the pixel s...

Abstract

The invention discloses a rapid measuring device of width of a tobacco shred. The rapid measuring device of the width of the tobacco shred comprises a workpiece platform system, an illuminating system, an imaging system, a control system and a computer system. An LED (Light Emitting Diode) illuminating system irradiates on a tobacco shred bearing case which achieves the collection of images under the driving of a stepping motor. A computer achieves the image processing. The rapid measuring device of the width of the tobacco shred has the advantages of being compact in structure, high in degree of automation, accurate in computing and applied to high-precision measure of the width of the tobacco shred.

Description

technical field [0001] The invention relates to a compact blade width measuring device, which is used for on-line measurement, computer vision and industrial automatic detection. It belongs to the field of industrial automation measurement and digital image processing. Background technique [0002] The shredded leaf width is the main quality index of the shredded leaf cutting process. The width of the shredded leaf in the shredded leaf shredded process of the tobacco industry in my country ranges from 0.7 to 1.1mm, and the tolerance is ±0.1mm. The width of shredded leaf has a certain degree of influence on the physical index and sensory quality of cigarettes: in the process of shredded tobacco sheet, with the increase of shredded width, the yield of shredded leaf increases correspondingly, and the ash loss rate decreases; However, when the shredded leaves are too wide, the rolled cigarettes tend to be empty, with poor combustibility and slow ignition speed of the cigarettes...
