[0035] In view of the deficiencies in the prior art, the present inventors have long studied and practiced to come up with the technical solution of the present application. The technical solution, its implementation process and principles will be further explained as follows.
[0036] In the following description, many specific details are set forth in order to provide a thorough understanding of the present application. However, the present application can be practiced in a variety of ways beyond the specific embodiments described herein, and the scope of the present application is not limited to the specific embodiments disclosed below.
[0037] Moreover, relational terms such as "first" and "second", and the like can be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual relationship or order between such entities or actions.
[0038] Referring to Figures 1-2a , Figure 2b and Figures 3a-3g , the present application provides a positioning identifier for shelf layer plate (hereinafter referred to as "positioning identifier"), which comprises an identifier body 10, a fixing mechanism 20 and an image acquisition unit 30; the fixing mechanism 20 and the image acquisition unit 30 are both fixed on the identifier body 10; the fixing mechanism 20 can fix the identifier body 10 on the frame structure of the shelf layer plate, and when the identifier body 10 is fixed on the frame structure of the shelf layer plate, the image acquisition unit 30 can acquire the image of the graphic code 61 on the surface of the target object 60 stored in the storage space 52 of the shelf layer plate; the identifier body 10 can at least generate and indicate and / or output the storage information for embodying the storage state in the storage space 52 based on the image of the graphic code 61.
[0039] In some embodiments, the positioning identifier can further comprise a light supplement unit 40, which can control a plurality of light supplement sources 51, and when the light supplement unit 40 is fixed on the top of the storage space 52 of the shelf layer plate, the plurality of light supplement sources 51 can supplement light to the storage space 52 at multiple angles.
[0040] In some embodiments, the identifier body 10 can control multiple light supplement sources 51 to perform multi-angle sequential light supplement. For example Figure 3a 、 Figure 3c and Figure 3e As shown, the light supplement sources 51 can be arranged in a linear array, for example, a strip-shaped light band with 10 lamp beads, and the arrangement direction of the light supplement sources 51 is preferably transverse to the image acquisition unit 30. At this time, the 10 lamp beads can be sequentially turned on to generate different light supplement angles, thereby avoiding reflection or glare caused by a certain angle and the surface of the target object 60. In addition to linear arrangement, the multi-angle light supplement effect can also be achieved by peripheral dispersion or matrix arrangement.
[0041] Specifically, in some embodiments, the multiple light supplement sources 51 can be arranged in a linear array, and the head and tail of the linear array are respectively arranged on both sides of the storage space 52; the identifier body 10 can control the multiple light supplement sources 51 to perform linear sequential light supplement.
[0042] In other embodiments, the light supplement angles of the multiple light supplement sources 51 can include a first light supplement angle 41 (as shown in Figure 3a , a second light supplement angle 52 (as shown in Figure 3b , and a third light supplement angle 43 (as shown in Figure 3c ); the first light supplement angle 41 and the third light supplement angle 43 irradiate from both sides of the storage space 52 to the middle of the storage space 52; the second light supplement angle 52 is arranged between the first light supplement angle 41 and the second light supplement angle 52, and irradiates from the top to the bottom of the storage space 52.
[0043] Each of the above light supplement angles can be individually turned on by a single light source, or simultaneously or separately turned on by multiple light sources on the same side.
[0044] In some embodiments, the identifier body 10 has a first control logic and a second control logic; the first control logic includes sequentially and cyclically supplementing light according to the first light supplement angle 41, the second light supplement angle 52, and the third light supplement angle 43; the second control logic includes sequentially and cyclically supplementing light according to the first light supplement angle 41, the third light supplement angle 43, and the second light supplement angle 52; and the identifier body 10 can switch between the first control logic and the second control logic.
[0045] The above preferred embodiment is a further improvement for the light compensation effect. The inventor has found in practice that, although the above multi-angle light compensation method can prevent misrecognition and missed recognition, for some target objects 60, it is often necessary to undergo light compensation irradiation at multiple angles before the pattern code 61 on the surface of the target object 60 can be accurately recognized, and then the target object 60 is recognized, which wastes time because the operator often needs to wait for feedback information about the target object 60 stored by the operator before leaving.
[0046] Therefore, as a further improvement of the present application, it is necessary to optimize the control logic for setting light compensation to optimize the selection of the most suitable light compensation sequence, thereby achieving more efficient recognition.
[0047] In some embodiments, the identifier body 10 can autonomously switch or be instructed to switch the first control logic / second control logic based on the characteristics of the target object 60.
[0048] In some embodiments, when the target object 60 has a symmetrical and / or shiny surface, the identifier body 10 can switch to the first control logic.
[0049] In some embodiments, when the target object 60 does not have a symmetrical and / or shiny surface, the identifier body 10 can switch to the second control logic.
[0050] As some typical application scenarios of the above technical solutions, when the target object 60 is a helmet, a box, a tablet, or other objects with symmetrical or shiny surfaces, it is often more suitable to use the first control logic corresponding to the sequential light compensation method from left to right or right to left. This is because it has symmetry, and if the second control logic is used, the first light compensation cannot be recognized, and switching to the symmetrical angle on the other side for light compensation will still produce the same amount of glare or reflection phenomenon, which will still affect recognition.
[0051] For some objects without symmetry, such as wrenches, ropes, and the like, the surface where the pattern code 61 is arranged may be relatively skewed, so the sequential light compensation method according to the first control logic often needs to be matched to obtain effective light compensation at the end. Therefore, it is more suitable for the second control logic that jumps and changes the light compensation at a large angle.
[0052] Therefore, at this time, the artificial indication switching light supplement control logic is adopted, or the information to be stored of the target object 60 is obtained (in the prior art, the information is often used to determine whether the target object 60 is correctly stored, which can be manually input or imported from a computer, etc., which is a common technical means), the symmetry and / or reflectivity of the target object 60 are determined according to the object name or other related attribute information contained in the information to be stored, or the information about the symmetry and / or reflectivity of the target object 60 is added in the information to be stored, which can be accepted by the control unit (such as a circuit board and / or a microcomputer and / or a single-chip microcomputer) in the recognizer main body 10.
[0053] The above examples illustrate the application scenarios in which the light supplement logic can be set based on the characteristics of the stored target object 60. In addition, some more automatic light supplement logic control strategies are also illustrated in embodiments of the present application.
[0054] For example, in some embodiments, the recognizer main body 10 is also provided with a human body sensor for detecting the approach of a human body. The recognizer main body 10 can count the number of light supplements performed from the detection of the approach of a human body to the identification of the target object 60. When the number of light supplements exceeds a predetermined threshold, the recognizer main body 10 performs the switching of the first control logic / second control logic.
[0055] In a specific application scenario, as shown in Figures 3a-3g When the light supplement is performed in the order of 1-10, the first control logic is corresponded at this time. If the object is identified after the light supplement to the 8th light source or the object is still not identified after the light supplement for more than 2 cycles after the approach of a human body to the positioning recognizer or the clicking of a control panel by an operator, the object is probably an asymmetric object, and the second control logic should be switched to, and the light supplement is preferably performed in the mode of 1, 10, 5, 9, 2, 5, 8, 3, 5,..., so that the target object 60 can be accurately identified generally after the second light supplement, i.e., when the 10th light source 51 is lit.
[0056] That is, when the number of light supplement lamps is more than 5, the second light supplement angle corresponds to the middle light source (the total number of light sources is odd) or two light sources (the total number of light sources is even), and the first light supplement angle and the third light supplement angle correspond to the light sources gradually close to the middle in each cycle, and then gradually move away from the two sides when close to the light source corresponding to the second light supplement angle, so as to realize the left-right-middle jumping cycle light supplement.
[0057] In some embodiments, the recognizer main body 10 is also provided with a positioning indicator light 11 for indicating whether the target object 60 is correctly prevented in the object storage space 52.
[0058] In some embodiments, the identifier body 10 is further provided with an information display unit 12 for displaying the storage information.
[0059] In some embodiments, the identifier body 10 is further provided with an input unit for inputting positioning indication information indicating the preset placement state of the target object 60.
[0060] In some embodiments, the fixing mechanism 20 comprises a hanging buckle structure matching the connecting structure on the frame structure. This structure is also commonly seen in the prior art, for example, a plurality of clamping groove structures are arranged on half of the frame structure of the shelf, and the end of the fixing mechanism 20 can be provided with a corresponding insertion piece inserted into the clamping groove; or in another embodiment, the end of the fixing mechanism 20 is provided with a magnetic attraction or adhesive member, which can realize fixed connection.
[0061] In some embodiments, the input unit is also used for inputting light supplement indication information indicating switching of the first control logic / second control logic.
[0062] The above settings all belong to common settings in the art, for example, common programmable microcomputers, PLC control systems and their display screens, etc., and the image recognition method, especially the recognition method for graphic codes, has provided a large amount of prior art in the art, and the control logic provided by the present application does not involve complex algorithms, therefore, based on the basic programming skills of the PLC controller, the person skilled in the art has the ability to write the corresponding control program under the indication of the technical solution provided by the present application.
[0063] The key technical means of the present application is still to provide a scheme for directly intelligentizing the existing shelf, and further to provide an optimized implementation mode for improving the recognition accuracy and efficiency, rather than a specific program algorithm.
[0064] Continuing to refer to Figures 3a-3g and referring to Figure 4 , the embodiment of the present application provides a positioning and identifying shelf, which comprises a shelf layer plate and a frame structure, the frame structure layerwisely fixes the shelf layer plate as a plurality of storage spaces 52; the frame structure is fixed with the shelf layer plate special positioning identifier provided by any of the above embodiments.
[0065] In some embodiments, the top of the storage space 52 is provided with a plurality of light supplement light sources 51, and the plurality of light supplement light sources 51 are respectively controlled by the shelf layer plate special positioning identifier whether to be turned on.
[0066] In some embodiments, a positioning pattern 53 is further arranged on the placement surface of the placement space 52, for position recognition of a plurality of target objects 60 placed in the placement space 52 based on the relative position of the positioning pattern 53.
[0067] In some embodiments, the positioning pattern 53 can include a ruler. Of course, in addition to the ruler, other kinds of positioning patterns 53 can also be used, such as letters, patterns of specific shapes, etc., and relevant image recognition + relative position determination methods are well known in the prior art, for example, the numbers in the ruler and the graphic code 61 can be detected by detecting boxes, and then the relative position can be calculated based on the coordinates of the detection boxes, which will not be described here.
[0068] Continuing to refer to Figures 1-2a , Figure 2b and Figures 3a-3g and Figure 4 , the present application also provides an identification method of a shelf board special positioning recognizer, applied to the above-mentioned positioning recognizer, including the following steps:
[0069] controlling a plurality of light supplementing light sources 51 to supplement light at multiple angles, and when supplementing light multiple times, acquiring image information of the placement space 52 of a plurality of shelf boards through the image acquisition unit 30 of the shelf board special positioning recognizer.

[0071] generating placement information corresponding to the target object 60 based on the identity information, the placement information at least reflecting whether the target object 60 is correctly placed and / or the in-place / out-of-place state of the target object 60.
[0072] In some embodiments, a positioning pattern 53 is arranged on the placement surface of the placement space 52, and based on the relative position of the graphic code 61 image and the positioning pattern 53, the positioning information of the corresponding target object 60 is generated, and the placement information is made to contain the positioning information.
[0073] In some embodiments, the light supplementing angles of a plurality of the light supplementing light sources 51 include a first light supplementing angle 41, a second light supplementing angle 52, and a third light supplementing angle 43; the first light supplementing angle 41 and the third light supplementing angle 43 irradiate from both sides of the placement space 52 to the middle part of the placement space 52; the second light supplementing angle 52 is arranged between the first light supplementing angle 41 and the second light supplementing angle 52, and irradiates from the top to the bottom of the placement space 52.
[0074] The control of the light supplement source 51 includes first control logic and second control logic; the first control logic includes sequentially circulating light supplement according to the order of the first light supplement angle 41, the second light supplement angle 52 and the third light supplement angle 43; and the second control logic includes circulating light supplement according to the order of the first light supplement angle 41, the third light supplement angle 43 and the second light supplement angle 52.
[0075] In some embodiments, when the target object 60 has symmetry and / or a shiny surface, the identifier main body 10 can switch to the first control logic; and / or when the target object 60 does not have symmetry and / or a shiny surface, the identifier main body 10 can switch to the second control logic.

[0077] The technical solutions of the present application are further described in detail below through several embodiments in combination with the accompanying drawings. However, the selected embodiments are only used to illustrate the present application, and do not limit the scope of the present application.
[0078] Embodiment 1
[0079] This embodiment illustrates a special positioning identifier for shelf panels, which provides a long strip-shaped identifier that can be fixed to the frame structure in front of the shelf panel 50 by a hanging buckle as a fixing mechanism 20. The front of the identifier main body 10 is provided with no less than one positioning indicator light 11 and no less than one storage location information display. The rear of the identifier main body 10 is provided with no less than one image acquisition unit 30, which is installed in front of the partition plate of the upper layer of the target identification layer. The image acquisition unit 30 collects image information of the objects on the surface of the identification panel 50. Through data analysis of the image information, especially based on the graphic code 61 in the image (the graphic code 61 is pasted or painted on the target object 60), the identity information, quantity information and orientation information of the object are analyzed, the positioning indicator light 11 corresponding to the orientation is lit, and the data information is displayed on the identifier and / or transmitted to a higher-level management system through data transmission.
[0080] The back is also provided with a light supplement lamp connection port connected to a light supplement unit 40. The light supplement unit 40 controls the lighting of the light supplement lamp, which is arranged below the upper panel 50, and can drive the light supplement lamp to sequentially switch the light supplement to solve the influence of reflection on the image recognition effect.
[0081] The scale coordinate diagram is arranged on the identification layer layer plate 50 as a positioning pattern 53, and other types of patterns such as a pure digital pattern or a grid pattern can also be used to assist in positioning the physical space orientation of the object and arranging the sequence information.
[0082] In actual use, the object placed on the identification layer layer plate 50 is attached with an object unique identity information image code, and the form of the image code 61 is not limited to a bar code, a two-dimensional code, an image code, a color ring code, etc.
[0083] In specific operation, the image acquisition unit 30 collects the identification layer image information, processes and analyzes the image, and after obtaining the identity information and orientation information of the object, can drive the corresponding storage position indicator light to light up.
[0084] The identification method of the above-mentioned layer plate 50 special positioning identifier includes the following main steps:
[0085] 1. Fix the layer plate 50 special positioning identifier above the layer plate 50 in front of the identification layer.
[0086] 2. Place the object with the object identity information image code pasted on the identification area of the identification layer, and the object identification code is placed upwards.
[0087] 3. The image acquisition unit 30 collects the image information above the identification layer layer plate,
[0088] 4. According to the light intensity, drive the fill light to switch fill light in turn, and obtain multiple image information according to the fill light frequency.
[0089] 5. Intelligent analysis of image information, according to the information of the image code 61, check the identity information of the object, and according to the relationship between the position of the image code and the latitude and longitude of the scale ruler, determine the orientation information of the object.
[0090] 6. As shown in Figure 3b , Figure 3d , Figure 3f and Figure 3g , the calculation results of multiple images after analysis are superimposed to obtain the final calculation result, so as to reduce the probability of incorrect scanning and low recognition caused by insufficient light.
[0091] 7. According to the summary information, drive the corresponding indicator light to light up, and drive the display device to display data information.
[0092] 8. At the same time, according to the change information of the image, calculate the off-site and homing state information of the object, and support voice broadcast data information.
[0093] Therefore, the embodiment realizes the modification of the existing shelf layer plate, does not need to replace the existing shelf, and can make the shelf intelligent through simple modification, thereby saving a large amount of manpower and material resources. Meanwhile, the embodiment also solves the storage and identification problems of multiple target objects 60, realizes the accurate identification of the target objects 60 through multi-angle light supplementing, significantly reduces the missing identification and misidentification probability, and improves the management efficiency.
[0094] Embodiment 2
[0095] The embodiment is an example of a shelf layer plate special positioning identifier and an identification control method thereof, which is basically the same as that in Embodiment 1, and the difference mainly lies in the different light supplementing modes:
[0096] The storage position information display is an industrial touch screen, in which a light supplementing mode switching button is arranged, and the light supplementing mode can be switched from the 1-10 order to 1, 10, 5, 9, 2, 5, 8, 3, 5, and so on.
[0097] In actual application, the operator often puts the target object 60 back to the original place after taking it away. Therefore, if the operator finds that the identification of the target object 60 takes a long time each time, the light supplementing mode switching button can be clicked to switch to another light supplementing mode. In this way, when the target object 60 is identified again, the disadvantage of the previous light supplementing mode can be overcome, and the suitable light supplementing angle can be quickly found.
[0098] Embodiment 3
[0099] The embodiment is an example of a shelf layer plate special positioning identifier and an identification control method thereof, which is basically the same as that in Embodiment 2, and the difference mainly lies in the further improvement of the control method of the light supplementing mode:
[0100] The recognizer main body 10 is provided with an infrared human body proximity sensor. When the control unit in the recognizer main body 10, such as a single-chip microcomputer, counts that the light supplementing times after the human body approaches are more than 8 times, the light supplementing control logic is automatically switched to another one.
[0101] In this way, the light supplementing control logic can be automatically switched without manual switching by the operator, thereby reducing the management difficulty.
[0102] Based on the above embodiments, it can be clearly seen that the shelf layer plate special positioning identifier provided by the present application has a fixing mechanism 20, which can be connected and fixed to the frame structure of the shelf, and an image acquisition unit 30 is used to acquire images of the storage space 52 of the shelf. The storage state of the target object 60 is identified by identifying the graphic code 61 and its position arranged on the surface of the target object 60, and the placement state of the target object 60 can be indicated.
[0103] The shelf layer special positioning identifier and the identification method thereof can directly transform the existing shelf, avoid the economic and manpower waste caused by replacing the storage device in the prior art, and have significant economic value.
[0104] In addition, the preferred embodiment provided by the embodiment of the present application also optimizes the light supplement control logic, so that it can more automatically / switchably adapt to the target object 60 with different shapes or surface states, further improving the operation / management efficiency.
[0105] It should be understood that the above embodiments are only for illustrating the technical concept and characteristics of the present application, and the purpose is to enable those skilled in the art to understand the content of the present application and implement it, and cannot limit the protection scope of the present application. Any equivalent changes or modifications made in accordance with the spirit and essence of the present application shall be covered within the protection scope of the present application.
