Further, the slicer rate-determining steps are the control that microtome knife spacing is carried out according to distance between vertical line
System, and carry out sectioning.
Further, the weighing stage is to go out weighing device is arranged in slicer equipment export, to the smoked sheet after fragment
It weighs, and shows the weight of every piece of smoked sheet.
The technical program has a characteristic that
1, calculating process is detection sample with image, is completed in real time.
2, using the calculated result of high-definition image as foundation, precision is higher for slicer control.
3, it is sliced by setting weighing-appliance real-time detection as a result, avoiding loss caused by slicing processes failure.
Therefore, the technical program improves the slice efficiency and precision of irregular cigarette packet by image processing means, meets
Standard requirements have great practical application value.
Detailed description of the invention
Fig. 1 is overhaul flow chart of the invention；
Fig. 2 is equal part separation calculation schematic diagram of the invention；
Specific embodiment
In order to make those of ordinary skill in the art better understand the present invention, below with reference to embodiment and attached drawing to the present invention
Technical solution be described further.
Embodiment: a method of the control uniform fragment of cigarette packet, it is characterised in that: including light detection, Image Acquisition, figure
It as processing and calculates, slicer control, weighing stage, image procossing and calculating are completed by computer, and calculated result is used for
The control of slicer.
Specifically, the sequence between each step is that light detecting step, image are adopted such as the flow chart in Figure of description 1
Collect step, image procossing and calculates step, slicer rate-determining steps, weighing stage.It include wherein current in light testing result
Environmental light brightness instructs intensity of illumination provided by light compensating lamp by the brightness value；In image acquisition step, according to current environment
Brightness controls light filling LED light and carries out light filling, and triggering is taken pictures with the CCD camera of high definition optical lens simultaneously；Image
Projection correction, edge contour identification, equal part separation calculation are carried out according to the high-definition image of acquisition in processing and calculating step, and counted
Calculate the spacing of vertical line；Slicer rate-determining steps are adjusted according to the position that vertical line spacing carries out microtome knife, and are carried out
Fragment cutting；Weighing stage weighs to the smoked sheet for completing cutting, and shows weighing results, and wherein weighing results include each cigarette
The weight value and difference of piece, for being compared with standard.
Further, described image processing and calculating step are completed in real time after obtaining image.
Further, the light detection includes that environmental light brightness detects, and judges whether current environmental light brightness meets bat
Take the photograph requirement.
Further, image acquisition step includes light filling and takes pictures, and wherein light filling is completed by LED light source, is taken pictures logical
