Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of cigarette box shape detection, and in particular to a method, device, equipment and medium for determining the regularity of a cigarette box shape. Background Art

[0002] The current quality standards for cigarette products are mainly based on the basic product requirements that cigarette products should meet to enter the "market threshold" during design, production and circulation. With the development of the cigarette industry and the upgrading and changes in consumer demand, it is particularly important to strengthen the control of consumer experience indicators. The geometric regularity of cigarette boxes (referred to as cigarette boxes) is an important external characteristic indicator of consumer visual perception.

[0003] At present, the regularity detection of the geometric shape of cigarette boxes is mainly based on the image method. This method mainly uses an image capture device to collect images of the front view, side view, and top view of the cigarette box, combines image processing and analysis, calculates the squareness of the cigarette box, and measures the geometric regularity of the cigarette box through the squareness.

[0004] However, the above method has the following problems: First, in order to ensure that the tested cigarette box can be photographed from an undistorted angle, it is necessary to adjust the position and angle of the image capture device when using the image, but for different tested cigarette boxes, it is impossible to ensure that the position and posture of the image capture device remain completely consistent each time, which makes the geometric regularity between different tested cigarette boxes have large differences, resulting in low accuracy of shape regularity. Second, after the image is collected, it is necessary to use a variety of image processing tools to manually perform a series of image processing operations to finally obtain the squareness of the cigarette box. This process is not only cumbersome to operate, but also takes a lot of time. Third, the geometric regularity of the cigarette box cannot be effectively and comprehensively evaluated only by the squareness of the cigarette box. Based on this, there are technical problems such as incomplete evaluation dimensions, low accuracy and low determination efficiency of the geometric regularity of the cigarette box. Summary of the invention

[0033] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0034] Before introducing the technical solution, the application scenario of the embodiment of the present invention can be described first. The technical solution provided by the embodiment of the present invention can be applied in any scenario where the geometric regularity of a cigarette box needs to be evaluated.

[0035] With the development of the cigarette industry and the upgrading of consumer demand, the industry has attached more and more importance to the quality management of cigarette consumption experience. Experience quality is a comprehensive evaluation of the product's use function, performance, and user experience during use, based on the consumer's perspective, and the value-added part of the experience.

[0036] Embodiment 1

[0037] Figure 1 A flow chart of a method for determining the shape regularity of a cigarette box provided in an embodiment of the present invention is provided. This embodiment is applicable to any situation where a cigarette box needs to be evaluated for its geometric regularity. The method can be performed by a device for determining the shape regularity of a cigarette box. The device can be implemented in the form of software and / or hardware. The hardware can be an electronic device, such as a mobile terminal, a PC, or a server.

[0038] like Figure 1 As shown, the method for determining the shape regularity of a cigarette box includes:

[0039] S110, obtaining height data of the cigarette box to be inspected, first cross-sectional data corresponding to the first cross-sectional area, and second cross-sectional data corresponding to the second cross-sectional area.

[0040] The cigarette box to be tested is a cigarette box on which geometric regularity evaluation is to be performed. Optionally, the cigarette box to be tested can be a cigarette box for carrying at least one cigarette, or a cigarette box for carrying at least one cigarette box. In the following embodiments, the cigarette box to be tested is taken as an example of a cigarette box.

[0041] Among them, the first cross-section is different from the second cross-section. The first cross-section is a cross-section at a first preset distance from the top of the cigarette box to be detected; the second cross-section is a cross-section at a second preset distance from the top of the cigarette box to be detected, and the first preset distance is less than the second preset distance. In other words, the first cross-section is a cross-section close to the top of the cigarette box to be detected, and the second cross-section is a cross-section close to the bottom of the cigarette box to be detected. The first cross-section data refers to the first length data and the first width data corresponding to the first cross-section in the cigarette box to be detected. The second cross-section data refers to the second length data and the second width data corresponding to the second cross-section in the cigarette box to be detected. The height data refers to the height value determined according to the height data of the cigarette box to be detected. More specifically, the height data is the average value of at least one cigarette box height data, for example, the height data is the average value of the first cigarette box height data at the third preset distance from the left side of the front of the cigarette box to be detected and the second cigarette box height data at the fourth preset distance from the left side of the front of the cigarette box to be detected. Exemplarily, the schematic diagram of the cigarette box to be detected is shown in Figure 2 , the front of the cigarette box to be tested faces forward, the cross section in the upper part of the figure is the first cross section, and the cross section in the lower part of the figure is the second cross section. The schematic diagram of the first cross section data, the second cross section data and the cigarette box height measurement value can be found in Figure 2 The annotation text in .

[0042] In this embodiment, the height data of the cigarette box to be inspected, the first cross-sectional data corresponding to the first cross-sectional data, and the second cross-sectional data corresponding to the second cross-sectional data can be obtained by a tobacco digital projector. The tobacco digital projector is a precise and efficient measuring instrument integrating optics, machinery, and electricity, which can efficiently amplify and accurately detect the contours and surface shapes of various complex workpieces.

[0043] Specifically, see the schematic diagram of the tobacco digital projector Figure 3 ,like Figure 3 (a) is a front view of a tobacco digital projector, which includes a projection collection lens and a mobile platform facing the projection collection lens. Figure 3(b) is a top view of the mobile platform, which includes a fixing device for fixing the cigarette box to be tested, a rectangular transparent area is configured on the mobile platform, a light source is configured below the transparent area, and the center point of the light source is aligned with the center point of the projection acquisition lens. In the specific application process, the mobile platform is fixed with the cigarette box to be tested by the fixing device. When the tobacco digital projector is started, the mobile platform moves along the preset platform movement direction. In this process, the measurement data of the cigarette box to be tested is recorded by the projection acquisition lens.

[0044] Next, how to collect the first cross-sectional data, the second cross-sectional data and the height data by the tobacco digital projector is described in detail. Optionally, the specific implementation method of collecting the height data, the first cross-sectional data and the second cross-sectional data may include the following steps:

[0045] (1) When the cigarette box to be inspected is placed on a mobile platform of a tobacco digital projector in a first placement posture, first length data and second length data are collected based on the tobacco digital projector.

[0046] The first placement posture refers to placing the front of the cigarette box to be tested facing the projection acquisition lens of the tobacco digital projector, and the long side of the cross section of the cigarette box to be tested is consistent with the moving direction of the mobile platform. For example, the schematic diagram of the cigarette box to be tested placed on the mobile platform in the first placement posture is shown in FIG. Figure 4 , the first posture is as follows Figure 4 (a) shown.

[0047] Specifically, after placing the cigarette box to be tested on the fixing device in the first placement posture, the start control can be triggered in the start control page of the tobacco digital projector, and the mobile platform will move along the preset moving direction. In the process of the mobile platform driving the cigarette box to be tested to move, when the left edge of the cigarette box to be tested coincides with the center line of the projection collection lens, this is the collection starting point; when the right edge of the cigarette box to be tested coincides with the center line of the projection collection lens, this is the collection ending point. Thus, the first projection collection data of the cigarette box to be tested in the first placement posture can be obtained. The schematic diagram of the first projection collection data at this time can be seen in Figure 4 (b) The first projection acquisition data may represent the side length values ​​of the cross sections of the cigarette box to be detected at different heights. Thus, according to the specific position of the top of the cigarette box to be detected in the first projection acquisition data, the first preset distance and the second preset distance, the first length data of the first cross section and the second length data of the second cross section are determined.

[0048] (2) When the cigarette box to be inspected is placed on the mobile platform of the tobacco digital projector in the second placement posture, the first width data and the second width data are collected based on the tobacco digital projector.

[0049] The second placement posture refers to placing the side of the cigarette box to be tested directly against the projection collection lens of the tobacco digital projector, and the wide side of the cross section of the cigarette box to be tested is consistent with the moving direction of the mobile platform. For example, the schematic diagram of the cigarette box to be tested placed on the mobile platform in the second placement posture is shown in FIG. Figure 5 , the second posture is as follows Figure 5 (a) shown.

[0050] Specifically, after placing the cigarette box to be tested in the second placement posture on the fixing device, the start control can be triggered in the start control page of the tobacco digital projector, and the mobile platform moves along the preset moving direction. In the process of the mobile platform driving the cigarette box to be tested to move, the process of determining the second projection acquisition data of the cigarette box to be tested in the second placement posture is consistent with step (1), which will not be repeated here. The schematic diagram of the final second projection acquisition data can be seen in Figure 5 (b) The second projection acquisition data may represent the width values ​​of the cross sections of the cigarette box to be detected at different heights. Thus, according to the specific position of the top of the cigarette box to be detected in the second projection acquisition data, the first preset distance and the second preset distance, the first width data of the first cross section and the second width data of the second cross section are determined.

[0051] (3) When the cigarette box to be tested is placed on the mobile platform of the tobacco digital projector in the third placement posture, at least one cigarette box height data is collected based on the tobacco digital projector.

[0052] The third placement posture refers to placing the front of the cigarette box to be tested facing the projection acquisition lens of the tobacco digital projector, and the height side of the cigarette box to be tested is consistent with the moving direction of the mobile platform. For example, the schematic diagram of the cigarette box to be tested placed on the mobile platform in the third placement posture is shown in FIG. Figure 6 , the third position is as follows Figure 6 (a) shown.

[0053] Specifically, after placing the cigarette box to be tested in the third placement posture on the fixing device, the start control can be triggered in the start control page of the tobacco digital projector, and the mobile platform moves along the preset moving direction. In the process of the mobile platform driving the cigarette box to be tested to move, the process of determining the third projection acquisition data of the cigarette box to be tested in the third placement posture is consistent with step (1), which will not be repeated here. The schematic diagram of the final third projection acquisition data can be seen in Figure 6 (b) The third projection acquisition data can represent the height values ​​of the cigarette box to be detected at different positions, that is, at least one cigarette box height data. Therefore, the height data of the cigarette box to be detected can be obtained by averaging the at least one cigarette box height data.

[0054] S120 : Determine a squareness evaluation attribute of the cigarette box to be inspected based on the first cross-sectional data and the second cross-sectional data.

[0055] The squareness evaluation attribute is used to characterize the degree to which the geometric shape of the cigarette box to be tested is close to a cube or a cuboid. For example, the larger the value of the squareness evaluation attribute, the closer the geometric shape of the cigarette box to be tested is to a cube or a cuboid; the smaller the value of the squareness evaluation attribute, the less close the geometric shape of the cigarette box to be tested is to a cube or a cuboid.

[0056] Specifically, the specific implementation method of determining the squareness evaluation attribute of the cigarette box to be tested based on the first cross-sectional data and the second cross-sectional data may include: determining the first cross-sectional area based on the first length data and the first width data of the first cross-sectional area; determining the second cross-sectional area based on the second length data and the second width data of the second cross-sectional area; determining the cross-sectional area ratio of the cigarette box to be tested based on the first cross-sectional area and the second cross-sectional area; determining the squareness evaluation attribute of the cigarette box to be tested based on the cross-sectional area ratio.

[0057] In this embodiment, the first cross-sectional area corresponding to the first cross-sectional area can be calculated according to the first length data and the first width data of the first cross-sectional data; the second cross-sectional area corresponding to the second cross-sectional area can be calculated according to the second length data and the second width data of the second cross-sectional data; thus, the cross-sectional area ratio can be determined according to the first cross-sectional area, the second cross-sectional area and the first preset function, wherein the first preset function can be expressed as: In the formula, F H Represents the cross-sectional area ratio of the cigarette box to be tested, S 1 represents the first cross-sectional area, S 2 represents the second cross-sectional area; thus, according to the cross-sectional area ratio and the first association relationship between the cross-sectional area ratio and the squareness attribute value set in advance, the squareness evaluation attribute of the cigarette box to be tested is determined. Wherein, the first association relationship includes: if the cross-sectional area ratio between the first cross-sectional area and the second cross-sectional area is closer to 1, the squareness evaluation attribute is greater; conversely, if the cross-sectional area ratio between the first cross-sectional area and the second cross-sectional area is less close to 1, the squareness evaluation attribute is smaller.

[0058] S130 : Determine the inclination evaluation attribute of the cigarette box to be inspected based on the first cross-sectional data, the second cross-sectional data and the height data.

[0059] The tilt evaluation attribute is used to characterize the tilt degree of the cigarette box to be detected. For example, the larger the value of the tilt evaluation attribute, the more serious the tilt degree of the cigarette box to be detected; the smaller the value of the tilt evaluation attribute, the less severe the tilt degree of the cigarette box to be detected.

[0060] In this embodiment, the inclination evaluation attribute of the cigarette box to be inspected can be determined based on the first length data in the first cross-sectional data, the second length data in the second cross-sectional data, and the height data; the inclination evaluation attribute of the cigarette box to be inspected can also be determined based on the first width data in the first cross-sectional data, the second width data in the second cross-sectional data, and the height data.

[0061] Exemplarily, the length difference between the first length data and the second length data can be determined, so that the tilt angle calculation value corresponding to the front of the cigarette box to be detected can be determined according to the height data and the length difference, so that the tilt evaluation attribute of the cigarette box to be detected can be determined according to the second association relationship between the tilt angle calculation value and the preset tilt angle and the tilt attribute value; it can also be determined that the width difference between the first width data and the second width data is determined, so that the tilt angle calculation value corresponding to the side of the cigarette box to be detected can be determined according to the height data and the width difference, so that the tilt evaluation attribute of the cigarette box to be detected can be determined according to the second association relationship between the tilt angle calculation value and the preset tilt angle and the tilt attribute value. Wherein, the second association relationship includes: if the tilt angle calculation value is closer to 90 degrees, the tilt evaluation attribute is greater; conversely, the less the tilt angle calculation value is closer to 90 degrees, the smaller the squareness evaluation attribute is.

[0062] S140: Determine the geometric regularity of the cigarette box to be inspected based on the squareness evaluation attribute and the inclination evaluation attribute.

[0063] The geometric regularity refers to the quantitative score of the geometric regularity of the cigarette box to be tested. For example, the higher the geometric regularity value, the better the geometric regularity of the cigarette box to be tested, and the lower the geometric regularity value, the worse the geometric regularity of the cigarette box to be tested.

[0064] In this embodiment, the geometric regularity of the cigarette box to be inspected may be determined according to a comprehensive quantitative value based on the squareness evaluation attribute and the inclination evaluation attribute.

[0065] Optionally, the specific implementation method of determining the geometric shape regularity of the cigarette box to be inspected based on the squareness evaluation attribute and the tilt evaluation attribute includes: determining the geometric shape regularity of the cigarette box to be inspected based on a preset squareness weight, a preset tilt weight, the squareness evaluation attribute and the tilt evaluation attribute.

[0066] The preset squareness weight and the preset inclination weight are both pre-set weight values. For example, the preset squareness weight can be expressed as W1, and the preset inclination weight can be expressed as W2. It should be noted that the values ​​of the preset squareness weight and the preset inclination weight are not specifically limited and can be adjusted according to the actual scenario.

[0067] In this embodiment, based on the squareness evaluation attribute and the inclination evaluation attribute, the weighted sum of the squareness evaluation attribute and the inclination evaluation attribute can be calculated according to the preset squareness weight and the preset inclination weight, and the final weighted sum result is determined as the geometric shape regularity of the cigarette box to be tested.

[0068] On the basis of the above-mentioned embodiment, a cigarette box sample regularity detection report including squareness evaluation attributes, inclination evaluation attributes and geometric shape regularity can also be generated. Thus, the user can improve the data basis for cigarette box production rectification according to the data content recorded in the cigarette box sample regularity detection report, so as to improve the geometric shape regularity of the cigarette box.

[0069] The technical solution of the embodiment of the present invention obtains the height data of the cigarette box to be detected, the first cross-sectional data corresponding to the first cross-sectional data, and the second cross-sectional data corresponding to the second cross-sectional data, and then determines the squareness evaluation attribute of the cigarette box to be detected based on the first cross-sectional data and the second cross-sectional data, and determines the inclination evaluation attribute of the cigarette box to be detected based on the first cross-sectional data, the second cross-sectional data, and the height data, thereby determining the geometric regularity of the cigarette box to be detected based on the squareness evaluation attribute and the inclination evaluation attribute. The technical solution provided by this embodiment does not require cumbersome manual operations, that is, it can automatically perform squareness evaluation and inclination evaluation processing according to the geometric measurement data of the cigarette box to be detected, and comprehensively evaluates the geometric regularity of the cigarette box through the squareness evaluation attribute and the inclination evaluation attribute, thereby improving the comprehensiveness of the evaluation dimension of the geometric regularity of the cigarette box, and improving the accuracy and determination efficiency of the geometric regularity of the cigarette box.

[0070] Embodiment 2

[0071] Figure 7 This is a flow chart of a method for determining the shape regularity of a cigarette box provided in the second embodiment of the present invention. Based on the above embodiment, S130 is further refined. The specific implementation method can refer to the detailed description of the embodiment of the present disclosure. The technical features that are the same or similar to the above embodiment are not repeated here.

[0072] like Figure 7 As shown, the method for determining the shape regularity of a cigarette box includes:

[0073] S210, obtaining height data of the cigarette box to be inspected, first cross-sectional data corresponding to the first cross-sectional area, and second cross-sectional data corresponding to the second cross-sectional area.

[0074] S220: Determine a squareness evaluation attribute of the cigarette box to be inspected based on the first cross-sectional data and the second cross-sectional data.

[0075] S230: Determine a first tilt angle calculation value based on the first length data, the second length data, the height data and the first preset slope function, so as to determine a front tilt evaluation attribute of the cigarette box to be tested based on the first tilt angle calculation value.

[0076] The front inclination evaluation attribute is used to characterize the inclination of the front of the cigarette box to be detected. The first preset inclination function refers to a function used to determine the inclination of the front of the cigarette box to be detected. The principle diagram of the first preset inclination function is shown in Figure 8 , the expression of the first preset slope function can be expressed as:

[0077]

[0078] In the formula, I z represents the first inclination angle calculation value, H represents height data, L1 represents first length data, and L2 represents second length data.

[0079] In this embodiment, the first length data, the second length data, and the height data can be substituted into the first preset slope function to obtain a first tilt angle calculation value corresponding to the front side of the cigarette box to be inspected; then, based on the first tilt angle calculation value and the second association relationship between the preset tilt angle and the tilt evaluation attribute, the tilt evaluation attribute of the cigarette box to be inspected is obtained.

[0080] S240: Determine a second inclination angle calculation value based on the first width data, the second width data, the height data and the second preset slope function, so as to determine a side inclination evaluation attribute of the cigarette box to be detected based on the second inclination angle calculation value.

[0081] The side slope evaluation attribute is used to characterize the slope of the side of the cigarette box to be detected. The second preset slope function refers to a function used to determine the slope of the side of the cigarette box to be detected. The expression of the second preset slope function can be expressed as:

[0082]

[0083] In the formula, I c represents the second inclination angle calculated value, H represents height data, W1 represents first width data, and W2 represents second width data.

[0084] In this embodiment, the first width data, the second width data, and the height data can be substituted into the second preset slope function to obtain a second inclination angle calculation value corresponding to the side of the cigarette box to be inspected; then, based on the second association relationship between the second inclination angle calculation value and the preset inclination angle and the inclination evaluation attribute, the side inclination evaluation attribute of the cigarette box to be inspected is obtained.

[0085] S250: Determine the inclination assessment attribute of the cigarette box to be inspected based on the front inclination assessment attribute and the side inclination assessment attribute.

[0086] In this embodiment, the front inclination evaluation attribute can be determined as the inclination evaluation attribute of the cigarette box to be detected; the side inclination evaluation attribute can also be determined as the inclination evaluation attribute of the cigarette box to be detected; the inclination evaluation attribute of the cigarette box to be detected can also be determined based on the weighted sum of the front inclination evaluation attribute and the side inclination evaluation attribute.

[0087] S260: Determine the geometric regularity of the cigarette box to be inspected based on the squareness evaluation attribute and the inclination evaluation attribute.

[0088] The technical solution of this embodiment, when determining the inclination evaluation attribute of the cigarette box to be detected based on the first cross-sectional data, the second cross-sectional data, and the height data, can determine the front inclination evaluation attribute of the cigarette box to be detected based on the first length data, the second length data, the height data, and the first preset slope function, and determine the side inclination evaluation attribute of the cigarette box to be detected based on the first width data, the second width data, the height data, and the second preset slope function, thereby determining the inclination evaluation attribute of the cigarette box to be detected based on the front inclination evaluation attribute and the side inclination evaluation attribute. The technical solution provided by this embodiment, by performing inclination evaluation processing on the front and side of the cigarette box to be detected, further improves the comprehensiveness of the evaluation dimension of the geometric regularity of the cigarette box, and improves the accuracy and determination efficiency of the geometric regularity of the cigarette box.
