In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
In order to better understand the technical solution, the technical solution will be described in detail with reference to the drawings and the specific embodiments.
A control method of an intelligent printing apparatus, a control device of an intelligent printing apparatus, and an intelligent printing apparatus proposed according to embodiments of the present invention are described below with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an intelligent printing apparatus according to an embodiment of the present invention. As shown in fig. 1, the control method of the intelligent printing apparatus includes the steps of:
and S1, collecting consumable image information of the intelligent printing equipment.
Optionally, in an embodiment of the present invention, a scanning device or a shooting device is installed on the intelligent printing apparatus, for example, by adding a cis scanning head or other image capturing devices to a paper output channel of the intelligent printing apparatus, and capturing consumable image information in real time by the cis scanning head or other image capturing devices.
Specifically, the consumable image information may include a paper out image.
That is to say, the paper outlet on the paper outlet channel can be scanned or shot by the scanning device or the shooting device arranged on the paper outlet channel of the intelligent printing equipment so as to collect the paper outlet image.
And S2, performing feature extraction on the consumable image information to acquire consumable parameters of the intelligent printing equipment, and controlling the intelligent printing equipment according to the consumable parameters.
Alternatively, in one embodiment of the present invention, the consumable image information, such as the paper-out image, may be subjected to recognition processing by an image recognition algorithm, thereby obtaining pattern parameters on the paper-out image.
Specifically, step S2 includes: performing feature extraction on the paper output image to obtain pattern parameters of the paper output image, and judging whether printing paper of the intelligent printing equipment is matched with preset reference printing paper or not according to the pattern parameters of the paper output image; if the printing paper of the intelligent printing device is not matched with the preset reference printing paper, the intelligent printing device is controlled to send alarm information, and the intelligent printing device is controlled to stop printing.
That is to say, when the paper image is identified through the image identification algorithm, the paper image may be converted into a gray scale image, binarization processing is performed, then the pattern feature points are extracted, and then it is determined whether the paper currently printed by the intelligent printing device matches with the reference printing paper according to the pattern feature points, for example, a label pattern (e.g., a communicated label pattern, a rhyme label pattern, etc.) corresponding to the image to be printed is on the printing paper.
Therefore, the control method of the intelligent printing device of the embodiment identifies the paper image through the image identification algorithm, can automatically identify whether the current printing paper is the designated printing paper, realizes the function of binding the designated paper consumables of the intelligent printing device, and can play a role in anti-counterfeiting.
Alternatively, in another embodiment of the present invention, the consumable image information, such as the paper output image, may also be subjected to recognition processing by an image recognition algorithm, so as to obtain the flatness parameter of the paper output image.
Specifically, step S2 includes: performing feature extraction on the paper outlet image to obtain flatness parameters of printing paper of the intelligent printing equipment, and judging whether the printing paper meets preset printing conditions or not according to the flatness parameters of the printing paper; if the printing paper does not meet the preset printing condition, the intelligent printing equipment is controlled to send alarm information, and the intelligent printing equipment is controlled to stop printing.
The flatness refers to the degree of surface flatness, uneven bulging, uneven warping, and uneven warping of the paper.
That is to say, when the paper image is identified through the image identification algorithm, the flatness of the paper can be obtained by performing feature extraction on the paper image, and then whether the paper currently printed by the intelligent printing device meets the printing condition is judged according to the flatness, for example, whether the paper currently printed by the intelligent printing device is flat is judged by setting a flatness threshold value, if the unevenness of the currently printed paper is identified, it is indicated that the printing paper of the intelligent printing device does not meet the printing condition, alarm information is generated, the intelligent printing device is controlled to send out the alarm information, a prompt is given, and the intelligent printing device is controlled to stop printing.
Therefore, the control method of the intelligent printing device of the embodiment can automatically identify whether the current printing paper is flat or not by identifying the paper image through the image identification algorithm, give an alarm when the current printing paper is identified to be uneven, control the intelligent printing device to stop printing, avoid paper jam in the printing process and improve the printing quality.
Optionally, in a further embodiment of the present invention, the step S2 includes: and carrying out feature extraction on the paper outlet image to acquire the width parameter of printing paper of the intelligent printing equipment, and limiting the effective printing width of the intelligent printer according to the width parameter of the printing paper.
The width calculation principle of the paper consumables is that the background color of the printing equipment when the paper consumables are not put in is recorded firstly, and thus when the paper consumables are put in, the area different from the background color is the width of the paper consumables.
That is to say, compare the processing through the image processing algorithm to going out the paper image and the image when not putting into the paper consumptive material, can calculate out the width of beating printing paper to control the smart machine according to the width of beating printing paper and print, thereby can control intelligent printing machine and switch the paper consumptive material of various width at will and print, avoid the wasting of resources.
Optionally, in a further embodiment of the present invention, consumable image information such as paper output images may also be processed by an optical flow algorithm, and a change between two adjacent frames of images is evaluated by the optical flow algorithm, so as to detect whether a paper jam occurs in the intelligent printing apparatus.
Specifically, step S2 includes: performing feature extraction on the paper-out image in real time to obtain a line feature value of the paper-out image, and judging whether a difference value between the line feature value of the current paper-out image and the line feature value of the paper-out image at the previous moment is smaller than a preset threshold value or not; and if the difference value is smaller than the preset threshold value, judging that the intelligent printing equipment has a paper jam phenomenon, and controlling the intelligent printing equipment to stop printing.
Therefore, the control method of the intelligent printing device according to this embodiment can detect the feature difference between the current paper output image and the paper output image at the previous time through the optical flow algorithm, and when the feature difference is smaller than the preset threshold, determine that the current state of the intelligent printing device is jammed, control the intelligent printing device to stop printing in time, and avoid the damage of the intelligent printing device. The preset threshold value can be calibrated according to actual conditions.
Optionally, in yet another embodiment of the present invention, consumable image information, such as a paper output image, may be processed through a gray level statistics and a definition recognition algorithm, so as to calculate a paper output gray level value and a paper output definition, and adjust a printing parameter of the intelligent printing device according to the paper output gray level value and the paper output definition, thereby automatically adjusting a printing effect and improving a printing quality.
Specifically, step S2 includes: and performing feature extraction on the paper outlet image to acquire a paper outlet gray value and a paper outlet definition of the intelligent printing device, adjusting the heating time of the intelligent printing device according to the paper outlet gray value, and adjusting the rendering parameters of the intelligent printing device according to the paper outlet definition.
That is to say, in the printing process of intelligent printing equipment, carry out the feature extraction to going out paper image through grey level statistics and definition recognition algorithm to can calculate the play paper grey scale value and the play paper definition of intelligent printing equipment, and adjust intelligent printing equipment's heating time according to going out paper grey scale value, and adjust intelligent printing equipment's rendering parameters according to going out paper definition.
This is because if the intelligent printing device does not have a grayscale feedback mechanism, the machine may be in an active mode all the time, and the temperature of the heating head chip of the machine will rise to a very high value, and the printed content will be very dark or even blurred.
Therefore, the control method of the intelligent printing apparatus of the embodiment detects the gray value of the print content in real time by adding the scanning head to the paper outlet, and correspondingly reduces the heating time if the trend of thickening is found, and improves the heating time if the trend of thinning is found, thereby ensuring the printing quality. Meanwhile, if the definition is found to be reduced, namely tailing occurs in the printing process, local overheating is caused due to continuous heating of some points, then tailing is easy to occur in local printing content, the tailing problem is reduced by adjusting rendering parameters of the intelligent printing equipment, for example, an algorithm for improving the printing effect by improving the thermal history proportion, and the printing quality is improved.
In summary, the control method of the intelligent printing apparatus according to the embodiment of the present invention fully utilizes the function of the scanning head on the intelligent printing apparatus, so that the functions of the intelligent printing apparatus are diversified, and management and control of paper consumables, detection of paper jam, identification of paper consumable width, and automatic adjustment of printing quality can be achieved.
Specifically, according to an embodiment of the present invention, as shown in fig. 2, the control method of the intelligent printing apparatus described above includes the steps of:

And S203, judging whether the current paper image is matched with the specified image according to the anti-counterfeiting pattern. If yes, returning to the step S201; if not, step S204 is performed.
And S204, controlling the intelligent printing equipment to alarm and stop printing.
And S205, processing the paper image by adopting a flatness algorithm to obtain the paper flatness.
And S206, judging whether the current paper is flat or not according to the paper flatness. If yes, returning to the step S201; if not, step S204 is performed.
S207, processing the paper images in real time by adopting an optical flow algorithm to detect the characteristic difference between the current paper-out image and the paper-out image at the last moment.
And S208, judging whether the characteristic difference is smaller than a preset threshold value. If yes, judging that paper is jammed, and executing the step S204; if not, return to step S201.
S209, processing the paper-out image through gray level statistics and definition recognition algorithm, and calculating to obtain a paper-out gray level value and a paper-out definition.
S210, adjusting the heating time of the intelligent printing equipment according to the paper outlet gray value, and adjusting the rendering parameters of the intelligent printing equipment according to the paper outlet definition.
And S211, calculating the width of the current printing paper based on the width calculation principle of the paper consumable.
And S212, automatically limiting the effective printing width of the intelligent printing device to the calculated width of the current printing paper.
Therefore, according to the control method of the intelligent printing equipment, the cis scanning head or other image acquisition devices are arranged on the paper outlet channel, then consumable images are detected in real time, whether paper consumables are flat or not or whether anti-counterfeiting patterns exist is detected through image algorithms, whether paper jam occurs is detected through optical flow algorithms, the gray level and the definition of the images are calculated through the image algorithms, and then feedback is carried out, so that the printing effect can be automatically adjusted according to the fed parameters, and the printing roll surface can be kept clear in any environment. Meanwhile, the width of the paper consumables is calculated through an image algorithm, so that the intelligent printing equipment can switch the paper consumables with various widths at will.
It should be noted that the image algorithm, the pattern recognition algorithm, the optical flow algorithm, the gray and sharpness recognition algorithm, and the width detection algorithm for detecting the paper flatness are all common image processing algorithms in the field, and are not described in detail herein.
