FIG. 1 is a schematic diagram of an embodiment of an image capture system for capturing images of a cigarette stream. Fig. 2 is a flowchart illustrating steps of a method for detecting a messy smoke according to an embodiment of the present invention. Fig. 3 is an execution flow chart of the method for detecting the random smoke according to an embodiment of the present invention.
Referring to fig. 1, 2 and 3, an embodiment of the present invention provides a method for detecting a mixed smoke, which is used for detecting the mixed smoke of the smoke branch 100 conveyed along the conveying direction y. The cigarettes in the stream 100 are arranged horizontally and perpendicular to the transport direction y. The messy smoke detection method comprises the following steps:
s10, acquiring a first image of two sides of the cigarette flow 100 along the first horizontal direction x and a second image of the upper side of the cigarette flow 100. Wherein the first horizontal direction x is perpendicular to the transport direction y of the stream 100.
And S20, judging whether the messy smoke 101 exists or not according to the collected first image and the second image (see figures 4 to 6).
S30, if the messy cigarettes 101 exist, an alarm is given out, so that an operator is reminded of processing the messy cigarettes 101 in time, cigarette blockage and even halt are avoided, and cigarette quality defects are avoided.
According to the method for detecting the random cigarettes, the first images of the two sides of the passing cigarette stream 100 along the first horizontal direction x and the second image of the upper side of the cigarette stream 100 are collected in real time. Then, whether the messy smoke exists or not is judged according to the collected first image and the second image 101. And when the messy cigarettes 101 are judged to exist, an alarm is given out, so that an operator is timely reminded of processing the messy cigarettes 101, the phenomenon that the cigarettes are blocked or even shut down is avoided, and the quality defect of the cigarettes is avoided.
Fig. 4 is a schematic diagram of the garbled smoke of the smoke branch on the filter side. Figure 5 is a schematic diagram of a tobacco stream with gargling on the tobacco side.
Referring to fig. 4 and 5, in an embodiment, the step S20 specifically includes:
if a straight line exists in the first image, it is determined that the random smoke 101 exists. Since the first image is an image of both sides of the cigarette flow 100 in the first horizontal direction x, the image of both sides of the cigarette flow 100 in the first horizontal direction x should normally be an outline of each cigarette end, i.e. a circular arc-shaped outline (e.g. the first image of the filter side of the cigarette shown in fig. 4, and the first image of the cut tobacco side of the cigarette shown in fig. 5). Therefore, when no random cigarette 101 is present (i.e., in a normal case), only the outline of the circular arc shape (i.e., the outline of the tobacco-tobacco side or the cigarette-filter side) should be present in the first image; when the random smoke 101 is present, a straight line appears in the first image. Thus, if there is a straight line in the first image, it can be determined that there is a random cigarette in the cigarette flow 100.
Figure 6 is a schematic view of a stream of cigarettes with garbled smoke on the upper side.
Referring to fig. 6, in an embodiment, step S20 specifically includes:
if a straight line with an included angle with the first horizontal direction x larger than a preset value exists in the second image, the fact that the messy cigarette 101 exists is judged. Since the second image is an image of the upper side of the tobacco stream 100, the image of the upper side of the tobacco stream 100 should normally be a straight line profile parallel to the first horizontal direction x. Therefore, when no messy cigarettes 101 exist (i.e. under normal conditions), only a straight line parallel to the first horizontal direction x (i.e. the included angle with the first horizontal direction x is zero) should exist in the second image, cigarettes in cigarette branches may have a certain position error in actual production, and the cigarettes may have a certain position error as long as the position error is allowed within a certain error range, so that even if a straight line exists in the second image, the included angle with the first horizontal direction x is smaller than or equal to a preset value, the second image cannot be judged to have the messy cigarettes 101; when the messy smoke 101 exists, a straight line with an included angle with the first horizontal direction x larger than a preset value appears in the second image. Thus, if a straight line exists in the second image, the included angle between the straight line and the first horizontal direction x is greater than the preset value, and the cigarette flow 100 can be judged to have the messy cigarettes.
It should be noted that the preset value may be 1 °, 2 °, 3 °, or 4 °, and is not limited herein.
In an embodiment, step S20 specifically includes:
if no straight line exists in the first image and no straight line exists in the second image, wherein the included angle between the second image and the first horizontal direction x is larger than a preset value, it is judged that no messy cigarettes 101 exist in the cigarette flow 100. That is to say, it can be determined that no messy cigarette 101 exists in the cigarette branch 100 only if no straight line exists in the first images on both sides of the cigarette flow in the first horizontal direction and no straight line exists in the second image on the upper side of the cigarette branch, the included angle between the straight line and the first horizontal direction x is greater than the preset value.
In an embodiment, before step S10, the method further includes the steps of:
detecting whether a cigarette stream 100 passes through;
if the cigarette flow 100 is detected to pass through, acquiring the first image and the second image (i.e., executing step S10); if it is detected that no smoke tributary 100 passes through, the image acquisition is not limited (i.e., step S10 is not executed).
Fig. 7 is a schematic diagram of a random smoke detection device according to an embodiment of the invention.
Referring to fig. 1 and 7, based on the foregoing method for detecting a messy cigarette, the present invention further provides a messy cigarette detection device, which includes an image acquisition module, an image processing module 20, and an alarm module 30.
The image acquisition module comprises a first camera 11, a second camera 12 and a third camera 13. The first camera 11 and the second camera 12 are respectively arranged on two sides of the smoke branch 100 in the first horizontal direction x, and are used for collecting first images of two sides of the smoke branch 100 in the first horizontal direction x. The third camera 13 is disposed above the smoke branch 100, and is configured to collect a second image of the upper side of the smoke branch 100. Wherein the first horizontal direction x is perpendicular to the transport direction y of the stream 100.
The image processing module 20 is in communication connection with the first camera 11, the second camera 12 and the third camera 13. The image processing module 20 is configured to obtain a first image collected by the first camera 11 and the second camera 12 and a second image collected by the third camera 13, and determine whether the cigarette branch 100 has a messy cigarette according to the first image and the second image. The alarm module 30 is in communication connection with the image processing module 20, and is configured to send an alarm when the image processing module 20 determines that the cigarette branch 100 has the messy cigarette 101. Optionally, first camera 11, second camera 12 and third camera 13 are all integrated to be provided with the flash light to provide sufficient light when ambient light is not enough, be favorable to promoting the image acquisition quality, promote the accuracy that the indiscriminate cigarette detected.
In this way, the first camera 11, the second camera 12 and the third camera 13 are used for collecting the first image and the second image of the smoke branch 100, and the image processing module 20 is used for judging whether the smoke branch 100 has the messy smoke 101 according to the first image and the second image. If a messy cigarette 101 exists, the alarm module 30 sends out an alarm, so that an operator is timely reminded of processing the messy cigarette 101, cigarette blockage or even shutdown is avoided, and cigarette quality defects are avoided.
Further, when the image processing module 20 identifies that a straight line exists in the first image and/or a straight line exists in the second image, the included angle between the straight line and the first horizontal direction x is greater than a preset value, the image processing module 20 determines that the messy smoke 101 exists in the smoke branch 100. When the image processing module 20 does not recognize a straight line in the first image and does not recognize a straight line having an angle greater than a preset value with respect to the first horizontal direction x in the second image, the image processing module 20 determines that no messy smoke 101 exists in the smoke branch flow 100.
In the embodiment, the messy smoke detection device further comprises a controller 40, and the controller 40 is in communication connection with the image processing module 20 and the alarm module 30, so that the controller 40 can control the alarm module 30 to send out or not send out an alarm according to the judgment result of the image processing module 20. In this way, when the image processing module 20 determines that the messy smoke 101 exists, the controller 40 controls the alarm module 30 to issue an alarm. When the image processing module 20 judges that no messy smoke 101 exists, the controller 40 controls the alarm module 30 not to give an alarm. Alternatively, the alarm module 30 may be a sound and light alarm.
Further, the messy smoke detection device further comprises a detection module 50 in communication connection with the controller 40. The detection module 50 is configured to detect whether a cigarette flow 100 has passed therethrough. The controller 40 is further configured to control the first camera 11, the second camera 12 and the third camera 13 to perform image acquisition when the detection module 50 detects that the cigarette flow 100 passes through. Thus, when the detection module 50 detects that the cigarette stream 100 passes through, the controller 40 controls the first camera 11, the second camera 12 and the third camera 13 to perform image acquisition on the cigarette stream 100 passing through, so as to ensure that the alarm module 30 can send out an alarm in time when the cigarette stream 100 passing through has the messy cigarettes 101. When the detection module 50 detects that no smoke branch 100 passes through, the controller 40 controls the first camera 11, the second camera 12 and the third camera 13 to stop image acquisition. Alternatively, the detection module 50 may employ a photodetector.
In the embodiment, the messy smoke detection device further includes a router 60, and the image processing module 20 is in communication connection with the first camera 11, the second camera 12, and the third camera 13 through the router 60. In this way, the first image and the second image collected by the first camera 11, the second camera 12, and the third camera 13 are transmitted to the image processing module 20 through the router 60.
