Description

Technical Field

[0001] The present invention relates to the technical field of cigarette ash performance quality inspection, in particular to the application of machine vision technology in cigarette ash performance quality inspection, and more particularly to a real-time tracking and detection method for cigarette ash holding force. Background Art

[0002] Ash holding capacity is a key indicator for judging the ash quality of cigarette packages, and is directly related to the smoking quality of cigarette products. Although there are cigarette ash holding index detection equipment and related manual ash holding capacity detection methods in China, the existing technology has the following technical problems that need to be solved urgently:

[0003] The data processing process involves a large amount of data and is susceptible to interference. The method of taking a photo first and then identifying it requires identifying all the contents of the entire photo. This method not only increases the workload of data processing and reduces the detection rate, but may also be interfered by various other factors in the image, such as the different colors of cigarette butts, the hardware color of the machine itself, and the ashes dropped by cigarettes, etc.

[0004] The existing technology has large systematic errors and accidental errors. The existing technology requires human participation, is mixed with certain subjective factors, and cannot simulate the actual situation of the cigarette during the smoking process, which makes the mapping relationship between data and time problematic, and there is a certain gap between the validity of the data and the actual situation;

[0005] Existing technologies make it difficult to achieve stable experiments in a completely enclosed environment, which results in two deficiencies: first, experiments in an unenclosed environment are easily disturbed by external airflows, which has a certain impact on the accuracy of the data; second, a large number of cigarettes will be burned in the experiment, and the flow measurement smoke produced by the combustion will interfere with other detection instruments and equipment and staff in the same space if it is not centrally processed.

[0006] The Chinese invention application with a publication date of October 27, 2020: A scheme of a cigarette fly ash detection device and detection method based on machine vision attempts to simulate the human body's cigarette smoking action by clamping the test sample with a manipulator. During the simulated human smoking process, multiple groups of cameras are used to synchronously follow the cigarette burning process in real time with full information. Under the condition of non-impacting ash, the change in the crack area of ​​the cigarette burning ash column where the ash flies away and falls off is identified by collecting image differences and comparison, so as to calculate and characterize the situation of cigarette fly ash scattered outside the fixed point where the ash is ejected. However, this scheme still has certain limitations in solving the above technical problems, and there is still a lot of room for improvement. Summary of the invention

[0007] In view of the limitations of the prior art, the present invention proposes a real-time tracking and detection method for the ash holding force of cigarette packs. The technical solution adopted by the present invention is:

[0008] A real-time tracking and detection method for the ash holding capacity of a cigarette package comprises the following steps:

[0009] S1, obtaining the appearance parameters and detection mode of the cigarettes to be tested loaded on the cigarette holding turntable;

[0010] S2, initializing the region of interest of the cigarette to be detected according to the detection mode, and associating the rotation angle of the cigarette holding turntable during the initialization process with each region of interest one by one;

[0011] S3, obtaining a burning image of the cigarette to be detected and a rotation angle of the cigarette holding turntable when the burning image is taken, and tracking the cigarette to be detected according to the rotation angle of the cigarette holding turntable when the burning image is taken;

[0012] S4, based on the tracking result and appearance parameters of the cigarette to be tested and the region of interest associated with the rotation angle of the cigarette holding turntable when the ignition image is taken, detect the burning carbon line of the cigarette to be tested, determine whether the ash column of the cigarette to be tested has broken and fallen off, and record the ash holding force of the cigarette to be tested.

[0013] Compared with the prior art, the present invention realizes the fully automatic processing of processes such as cigarette tracking, burning carbon line detection, ash falling judgment, and ash holding capacity measurement, which reduces the probability of human error and effectively avoids the occurrence of accidental errors; by selecting the area of ​​interest, only useful areas are detected, and the detection range is narrowed, the scale of data to be processed can be reduced, the interference of environmental factors can be eliminated as much as possible, and the detection efficiency and detection accuracy can be improved; the automation of the detection process allows the detection experiment to be detected in a closed chassis, reducing the impact of external airflow on the experiment, and the flow measurement smoke generated during the detection process can also be extracted and processed.

[0014] As a preferred embodiment, the detection mode includes a static combustion mode; in the static combustion mode, in the steps S2 and S3, the rotation angle of the cigarette holding turntable is maintained at the zero position.

[0016] Furthermore, in step S4, the burning carbon line of the cigarette to be detected is detected by the following method:

[0017] According to the shape parameters of the cigarette to be detected and the area of ​​interest associated with the rotation angle of the cigarette holding turntable when the ignition image is taken, the unburned cigarette paper part of the cigarette to be detected in the ignition image is located; the brightness of the unburned cigarette paper part of the cigarette to be detected is detected, and the area closest to the center of the cigarette holding turntable and with lower brightness than the neighboring area is used as the burning carbon line.

[0018] Furthermore, in step S4, if the ignition image has detection interference caused by brightness jumps of the tipping paper edge of the cigarette to be detected, the region of interest is adjusted in real time and then re-detected.

[0019] Furthermore, in step S4, if the ignition image has detection interference caused by a sudden increase in brightness of the burning position of the cigarette to be detected, a secondary detection is performed on the brightness of the unburned cigarette paper part of the cigarette to be detected: the lowest brightness value in the neighborhood of the burning carbon line of the previous frame is obtained, and a brightness threshold is set according to the lowest brightness value, and the area in the current frame whose brightness is lower than the brightness threshold and is closest to the center of the cigarette holding turntable is taken as the burning carbon line.

[0020] Furthermore, it is determined whether the ash column of the cigarette to be tested has broken and fallen off by the following method:

[0021] According to the position of the burning carbon line, the distance between the ash end of the cigarette to be tested and the tipping paper is determined; the average brightness of the region of interest of the cigarette to be tested is obtained; if the distance between the ash end and the tipping paper and the average brightness of the region of interest suddenly decrease at the same time, it is determined that the cigarette to be tested has shed ash, and the ash holding force of the cigarette to be tested that has shed ash is recorded.

[0038] In order to solve the limitations of the prior art, this embodiment provides a technical solution, and the technical solution of the present invention is further described below in conjunction with the drawings and embodiments.

[0039] Example 1

[0040] Please refer to Figure 1 as well as Figure 2 A real-time tracking and detection method for the ash holding force of a cigarette package comprises the following steps:

[0041] S1, obtaining the appearance parameters and detection mode of the cigarettes to be tested loaded on the cigarette holding turntable;

[0042] S2, initializing the region of interest of the cigarette to be detected according to the detection mode, and associating the rotation angle of the cigarette holding turntable during the initialization process with each region of interest one by one;

[0043] S3, obtaining a burning image of the cigarette to be detected and a rotation angle of the cigarette holding turntable when the burning image is taken, and tracking the cigarette to be detected according to the rotation angle of the cigarette holding turntable when the burning image is taken;

[0044] S4, based on the tracking result and appearance parameters of the cigarette to be tested and the region of interest associated with the rotation angle of the cigarette holding turntable when the ignition image is taken, detect the burning carbon line of the cigarette to be tested, determine whether the ash column of the cigarette to be tested has broken and fallen off (commonly known as "ash falling"), and record the ash holding force of the cigarette to be tested.

[0045] Compared with the prior art, the present invention realizes the fully automatic processing of processes such as cigarette tracking, burning carbon line detection, ash falling judgment, and ash holding capacity measurement, which reduces the probability of human error and effectively avoids the occurrence of accidental errors; by selecting the area of ​​interest, only useful areas are detected, and the detection range is narrowed, the scale of data to be processed can be reduced, the interference of environmental factors can be eliminated as much as possible, and the detection efficiency and detection accuracy can be improved; the automation of the detection process allows the detection experiment to be detected in a closed chassis, reducing the impact of external airflow on the experiment, and the flow measurement smoke generated during the detection process can also be extracted and processed.

[0046] Specifically, the shape parameters of a cigarette include the length of the cigarette and the length of the cigarette butt, etc. The burning carbon line of the cigarette involved in this embodiment refers to the black outline produced by the cigarette during the burning process.

[0047] The region of interest is ROI (region of interest); as an optional embodiment, the real-time tracking and detection method of the ash holding capacity of the cigarette package can be developed and implemented based on OPENCV using CPP.

[0048] The rotation angle of the cigarette holding turntable is controlled by a motor output of a programmable controller (PLC). On the equipment that implements the real-time tracking and detection method of the ash holding force of the cigarette pack, when executing step S3, the rotation angle of the cigarette holding turntable can be obtained by allowing the main control computer to maintain communication with the programmable controller.

[0049] In an optional embodiment, the rotation angle of the cigarette holding turntable during the initialization process is associated with each region of interest one by one, which can be achieved by numbering each region of interest according to the rotation angle.

[0050] The ignition image can be captured by an industrial camera; as an optional embodiment, the industrial camera captures an ignition image every 0.8 seconds, which is much faster than the naked eye, greatly improving the speed and efficiency of cigarette ash retention rate detection and reducing manpower consumption.

[0051] The real-time tracking detection method for the ash holding capacity of cigarette packages can detect a number of cigarettes at the same time. After all the cigarettes to be detected have shed ash, the detection can be ended, and the experimenter can sort out the data.

[0052] As a preferred embodiment, the detection mode includes a static combustion mode; in the static combustion mode, in the steps S2 and S3, the rotation angle of the cigarette holding turntable is maintained at the zero position.

[0053] As a preferred embodiment, the detection mode includes a suction and combustion mode; in the suction and combustion mode, in the steps S2 and S3, the rotation angle of the cigarette holding turntable is ten positions starting from a zero position and increasing by 36 degrees.

[0054] Specifically, the diversification of detection modes can reduce the system error of previous detection technologies. In the suction and burning mode, a suction mechanism can also be set to periodically suck the cigarette to be detected, imitating the real suction process, so the suction and burning mode can also be called a rotary suction mode; during detection, whether in static combustion mode or suction and burning mode, the cigarette holding turntable will only stop at a fixed position, such as in static combustion mode, it will only stop at zero point, and in suction and burning mode, it will only stop at ten places such as zero point, 36 degrees, and 72 degrees, and then rotate 36 degrees after suction. Therefore, after determining the ROI corresponding to each cigarette at each angle in the initialization stage, the next time the turntable rotates to the corresponding angle, the corresponding cigarette can be found through the ROI corresponding to this angle to achieve tracking detection of the cigarette.

[0055] Furthermore, in step S4, the burning carbon line of the cigarette to be detected is detected by the following method:

[0056] According to the shape parameters of the cigarette to be detected and the area of ​​interest associated with the rotation angle of the cigarette holding turntable when the ignition image is taken, the unburned cigarette paper part of the cigarette to be detected in the ignition image is located; the brightness of the unburned cigarette paper part of the cigarette to be detected is detected, and the area closest to the center of the cigarette holding turntable and with lower brightness than the neighboring area is used as the burning carbon line.

[0057] Furthermore, in step S4, if the ignition image has detection interference caused by brightness jumps of the tipping paper edge of the cigarette to be detected, the region of interest is adjusted in real time and then re-detected.

[0058] Specifically, by continuously correcting and checking the ROI area during the detection process, the interference caused by the brightness jump at the edge of the cigarette tipping paper can be eliminated, and the detection accuracy of the burning carbon line can be further improved.

[0059] Furthermore, in step S4, if the ignition image has detection interference caused by a sudden increase in brightness of the burning position of the cigarette to be detected, a secondary detection is performed on the brightness of the unburned cigarette paper part of the cigarette to be detected: the lowest brightness value in the neighborhood of the burning carbon line of the previous frame is obtained, and a brightness threshold is set according to the lowest brightness value, and the area in the current frame whose brightness is lower than the brightness threshold and is closest to the center of the cigarette holding turntable is taken as the burning carbon line.

[0060] Specifically, the brightness threshold can be obtained by adding a smaller number to the minimum brightness value in the neighborhood of the burning carbon line of the previous frame. By performing secondary detection in the above manner, the loss of the burning carbon line caused by excessive brightness can be effectively avoided, thereby further improving the detection accuracy of the burning carbon line.

[0061] As a preferred embodiment, whether the ash column of the cigarette to be tested has broken and fallen is determined by the following method:

[0062] According to the position of the burning carbon line, the distance between the ash end of the cigarette to be tested and the tipping paper is determined; the average brightness of the region of interest of the cigarette to be tested is obtained; if the distance between the ash end and the tipping paper and the average brightness of the region of interest suddenly decrease at the same time, it is determined that the cigarette to be tested has shed ash, and the ash holding force of the cigarette to be tested that has shed ash is recorded.

[0063] Specifically, during the burning process of a cigarette, the ash may droop but not fall off, and the sudden change in brightness at the inhalation position and the smoke produced by the combustion may also affect the detection. The above method can be used to accurately determine the ash falling of a cigarette.

[0066] The preset parameter acquisition module 1 is used to acquire the appearance parameters and detection mode of the cigarettes to be detected loaded on the cigarette holding turntable;

[0067] The initialization module 2 is used to initialize the region of interest of the cigarette to be detected according to the detection mode, and associate the rotation angle of the cigarette holding turntable during the initialization process with each region of interest one by one;

[0068] The tracking module 3 is used to obtain the burning image of the cigarette to be detected and the rotation angle of the cigarette holding turntable when the burning image is taken, and track the cigarette to be detected according to the rotation angle of the cigarette holding turntable when the burning image is taken;

[0069] The judgment and recording module 4 is used to detect the burning carbon line of the cigarette to be detected, determine whether the ash column of the cigarette to be detected has broken and fallen, and record the ash holding force of the cigarette to be detected based on the tracking results, appearance parameters of the cigarette to be detected and the area of ​​interest associated with the rotation angle of the cigarette holding turntable when the ignition image is taken.
