Image code information binding technology refers to the corresponding binding of image information and identification information, which can be applied in technical fields such as article security inspection.

For example, a judgment is made based on the time of image information collection, the time of identification information collection, and a preset time to determine whether the corresponding image information and identification information belong to the same item and thus determine whether binding can be performed.

[0056] An information binding method, apparatus, device, and computer-readable storage medium are provided in the embodiments of the present application, which are described in detail below.

[0057] The information binding method in the embodiment of the present application is applied to an information binding device, which is arranged in an electronic device.

[0058] like Figure 1 As shown, Figure 1 This is a scenario diagram of the information binding method in an embodiment of the present application. The information binding scenario in the embodiment of the present application includes an electronic device 100 (an information binding device is integrated in the electronic device 100), and a computer-readable storage medium corresponding to the information binding is run in the electronic device 100 to execute the information binding steps.

[0059] Understandably, Figure 1 The electronic devices in the information binding scenario shown, or the devices included in the electronic devices, do not constitute a limitation on the embodiments of the present application. That is, the number of devices and types of devices included in the information binding scenario, or the number of devices and types of devices included in each device, do not affect the overall implementation of the technical solution in the embodiments of the present application, and can all be regarded as equivalent replacements or derivatives of the technical solution claimed to be protected in the embodiments of the present application.

[0060] In the embodiment of the present application, the electronic device 100 is mainly used for: obtaining image information of the object to be detected collected by the first device, and identification information of the object to be detected collected by the second device; obtaining the running distance of the object to be detected from the completion of the image information collection to the completion of the identification information collection, wherein the running distance is obtained by a speed encoder; and binding the image information and the identification information according to the running distance to obtain an image identification group.

[0061] In the embodiment of the present application, the electronic device 100 may be an independent electronic device, or an electronic device grid or electronic device cluster composed of electronic devices. For example, the electronic device 100 described in the embodiment of the present application includes but is not limited to a computer, a grid host, a single grid electronic device, a plurality of grid electronic devices, or a cloud electronic device composed of a plurality of electronic devices. The cloud electronic device is composed of a large number of computers or grid electronic devices based on cloud computing.

[0062] Those skilled in the art will understand that Figure 1 The application environment shown in the figure is only one application scenario of the present application solution and does not constitute a limitation on the application scenario of the present application solution. Other application environments may also include Figure 1 More or fewer electronic devices as shown, or electronic device grid connection relationships, such as Figure 1 Only one electronic device is shown. It can be understood that the information binding scenario may also include one or more other electronic devices, which are not specifically limited here; the electronic device 100 may also include a memory.

[0063] In addition, in the information binding scenario of the present application, the electronic device 100 may be provided with a display device, or the electronic device 100 may not be provided with a display device and may be communicated with an external display device 200, and the display device 200 is used to output the result of the execution of the information binding method in the electronic device. The electronic device 100 may access a backend database 300 (the backend database may be in the local memory of the electronic device, or may be set in the cloud), and the backend database 300 may store information related to information binding.

[0064] It should be noted that Figure 1 The scenario diagram of the information binding method shown is merely an example. The information binding scenario described in the embodiment of the present application is intended to more clearly illustrate the technical solution of the embodiment of the present application and does not constitute a limitation on the technical solution provided in the embodiment of the present application.

[0065] Based on the above information binding scenario, an embodiment of the information binding method is proposed. The information binding method in this embodiment is applied to an electronic device, and the type of the electronic device is not specifically limited. For example, the electronic device can be a terminal or a server. This embodiment takes the server as an example for description.

[0066] Figure 2 is a flowchart of an information binding method provided by an embodiment of the present application, such as Figure 2 As shown, the information binding method in the embodiment of the present application includes steps 201-203:

[0067] 201. Acquire image information of an object to be detected collected by a first device, and identification information of the object to be detected collected by a second device.

[0068] Among them, the above-mentioned items to be detected are items that need to be scanned to obtain multiple information (including image information and identification information), and the corresponding multiple information needs to be bound. The first device and the second device are devices for information scanning.

[0069] In this embodiment, the application of the above-mentioned information binding method to the field of express package security inspection is taken as an example for explanation. For example, when an express package is inspected, it will pass through a first device for image acquisition and a second device for identification acquisition in sequence, and the express packages are queued and continuously pass through the first device and the second device. At this time, the corresponding image information needs to be bound to the identification information so that when a certain express package is found to be abnormal, the abnormal package can be identified in time.

[0070] During the information collection process, what is usually obtained is a queue corresponding to the image information and a queue corresponding to the identification information. The information in the two queues needs to be bound one-to-one to determine the identification information corresponding to each image information.

[0071] In this embodiment, the information binding of an image information in the image information queue and an identification information in the identification information queue is used as an example for specific description. In actual use, multiple image information and identification information can be bound at the same time based on the information binding method provided in this embodiment. For example, each image information in the image information queue is used as the image information to be bound in this embodiment, and each identification information in the identification information queue is used as the identification information to be bound in this embodiment, so as to determine whether the two can be bound.

[0072] 202 , obtaining a running distance of the object to be detected from the completion of the image information acquisition to the completion of the identification information acquisition, wherein the running distance is obtained by a speed encoder.

[0073] It should be noted that in this embodiment, the first device is set before the second device for explanation, that is, the image information of the object to be detected is first collected by the first device, and then transmitted to the second device for identification information collection. However, in actual use, the first device can also be set after the second device, which is not specifically limited here.

[0074] The speed encoder is a device used to detect the speed of the motor. The speed encoder is connected to the conveying device used to transport the object to be inspected, so as to determine how far the conveying device has transported the object to be inspected. Specifically, the running distance is the distance actually transported by the conveying device from the time when the image information is collected to the time when the identification information is collected.

[0075] 203 : Bind the image information and the identification information according to the running distance to obtain an image identification group.

[0076] Specifically, in this embodiment, according to the above step 202, the running distance of the transmission device from the completion of the image information acquisition to the completion of the identification information acquisition can be obtained through the speed encoder, and the actual distance between the first device and the second device can also be determined. For example, the relative distance between the first device and the second device can be measured in advance. During normal use, the first device and the second device will not be displaced, so the relative distance between the first device and the second device can be regarded as unchanged. At this time, according to the running distance and the relative distance between the first device and the second device, it can be determined whether the image information and the identification information belong to the same object to be detected. If they belong to the same object to be detected, the information binding can be completed, thereby obtaining an image identification group consisting of matching image information and identification information.

[0077] In some embodiments of the present application, the object to be detected is conveyed from the first device to the second device via a conveyor belt;

[0078] A first photoelectric sensor is arranged at the exit of the first device, and a second photoelectric sensor is arranged at the exit of the second device.

[0079] Figure 3 is a schematic diagram of a flow chart of calculating a running distance provided in an embodiment of the present application, such as Figure 3 As shown, before obtaining the running distance of the object to be detected from the completion of the image information acquisition to the completion of the identification information acquisition, the method further includes:

[0080] 301, obtaining, by the speed encoder, a first belt revolution number when the first photoelectric sensor is triggered by the object to be detected, and a second belt revolution number when the second photoelectric sensor is triggered by the object to be detected;

[0081] 302. Determine the running distance according to the first number of belt turns and the second number of belt turns.

[0082] Figure 4 is a schematic diagram of a specific scenario of information collection provided by an embodiment of the present application, such as Figure 4 As shown, the object to be detected is sequentially conveyed to the first device and the second device via a conveyor belt. A first photoelectric sensor is set at the exit of the first device, and a second photoelectric sensor is set at the exit of the second device. A speed encoder is connected to the conveyor belt to collect the number of revolutions of the rotating shaft of the conveyor belt, that is, the number of belt revolutions, so as to determine the running distance.

[0083] In some embodiments of the present application, the first photoelectric sensor is arranged close to the first device, and the second photoelectric sensor is arranged close to the second device, so that the corresponding running distance can be quickly sensed and determined after the image information collection and identification information collection of the object to be detected are completed, which is conducive to improving the accuracy of the acquired running distance.

[0084] In some embodiments of the present application, the running distance is determined according to the difference between the second belt turns and the first belt turns, and a pre-set turn distance parameter. The speed encoder records the number of turns of the rotating shaft of the conveyor belt, and the turn distance parameter is a pre-set parameter used to determine how far the conveyor belt travels when the rotating shaft rotates one turn. For example, the turn distance parameter is 6 meters / turn, which means that the conveyor belt travels 6 meters when the rotating shaft rotates one turn. If the difference between the second belt turns and the first belt turns is 0.5, the corresponding running distance can be determined to be 3 meters.

[0085] In some embodiments of the present application, the running distance calculation process may be further modified to improve the accuracy of the calculated running distance. Figure 4 As shown, a third photoelectric sensor may also be provided at the entrance of the second device, and the determining of the running distance according to the first belt circle number and the second belt circle number includes:

[0086] Obtaining a running circle difference according to the first belt circle number and the second belt circle number;

[0087] Acquire the third belt revolution number when the third photoelectric sensor is triggered by the object to be detected by the speed encoder, and acquire a corrected revolution difference according to the first belt revolution number and the third belt revolution number;

[0088] Obtaining a corrected standard distance, wherein the corrected standard distance is determined according to a historical corrected lap number difference corresponding to at least two historical objects to be detected and a preset lap number distance parameter;

[0089] The running distance is determined according to the running circle number difference, the corrected circle number difference and the corrected standard distance.

[0090] The running circle difference is the difference between the second belt circle and the first belt circle, and the corrected circle difference is the difference between the third belt circle and the first belt circle. The corrected standard distance is the distance from the exit of the first device to the entrance of the second device determined in advance using multiple tests.

[0091] It should be noted that in actual use, the preset circle distance parameter is usually an ideal parameter, but errors may occur as the equipment is used. For example, the preset distance parameter is inaccurate due to the belt being stretched for a long time or the belt being loose. Under ideal conditions, the speed encoder records that the belt transmits 6 meters when one circle, but in actual use, it may exceed 6 meters or be less than 6 meters. Therefore, if the actual calculation depends only on the distance parameter, it may cause errors.

[0092] In one application scenario, it is necessary to determine a corrected lap distance parameter so that the corrected reference distance calculated by the corrected lap distance parameter in actual use is equal to the corrected standard distance, thereby making the calculated running distance in actual use equal to the running distance calculated under ideal conditions.

[0093] In a specific example, during actual measurement, the corrected lap difference * corrected lap distance parameter = reference distance; under historical standard conditions, the historical corrected lap difference * preset lap distance parameter = corrected standard distance. When making corrections, it is necessary to have a reference distance = corrected standard distance, then the corrected lap distance parameter = corrected standard distance / corrected lap difference, and the corrected lap distance parameter * running lap difference = corrected running distance. Therefore, corrected standard distance / corrected lap difference * running lap difference = corrected running distance. In this way, the corrected running distance can be calculated, and information binding is performed based on the corrected running distance, which can improve the accuracy of information binding.

[0094] In some embodiments of the present application, before obtaining the corrected standard distance, the method further includes:

[0095] Acquire at least two historical corrected reference distances of the historical objects to be detected, wherein the historical corrected reference distances of the historical objects to be detected are determined according to the historical corrected lap number difference of the historical objects to be detected and the preset lap number distance parameter;

[0096] The corrected standard distance is determined according to the average of the historical corrected reference distances of the historical objects to be detected.

[0097] In this way, using multiple packages for testing in advance and determining the corrected standard distance based on the average of the historical corrected reference distances is conducive to improving the accuracy of the corrected standard distance obtained, thereby improving the accuracy of the correction of the running distance.

[0098] In some embodiments of the present application, when the running distance is equal to a preset distance value, the image information and the representation information may be bound to obtain an image identification group.

[0099] In some other embodiments of the present application, information binding is performed according to the target distance interval. Specifically, the information binding of the image information and the identification information according to the running distance to obtain the image identification group includes:

[0100] Acquire a target distance interval, wherein the target distance interval is determined according to historical running distances of at least two historical objects to be detected;

[0101] If the running distance belongs to the target distance interval, binding the image information and the identification information to obtain an image identification group;

[0102] If the running distance does not belong to the target distance interval, a binding prompt message is output.

[0103] In this way, information binding is performed according to the target distance interval. Binding can be achieved only if the running distance belongs to the target distance interval, and it is not required that the running distance is strictly equal to a certain distance value, which is conducive to improving the fault tolerance and success rate of information binding.

[0104] The binding prompt information is pre-set prompt information for indicating a binding failure, which can prompt the user that the information binding fails, thereby facilitating the user to check.

[0105] In some embodiments of the present application, before acquiring the target distance interval, the method further includes:

[0106] Obtaining historical running distances of at least two historical objects to be detected, wherein the historical running distances of the historical objects to be detected are determined according to the difference in the number of historical running laps of the historical objects to be detected and a preset lap distance parameter;

[0107] Calculate the average of the historical running distances of the historical objects to be detected as the running standard distance;

[0108] The target distance interval is determined according to the operating standard distance and a preset distance offset threshold, wherein the distance offset threshold is determined according to the distance between two adjacent objects to be detected.

[0109] The standard running distance is the running distance of the object to be detected in the process of completing image information collection and identification information collection based on the historical test results of the object to be detected. The distance offset threshold is used to adjust according to the standard running distance to determine the target distance interval for judgment; the distance offset threshold can be set and adjusted according to actual needs. It should be noted that the distance offset threshold is smaller than the distance between two adjacent objects to be detected to prevent the information of adjacent objects from being bound together.

[0110] In some embodiments of the present application, Figure 4 As shown, a fourth photoelectric sensor is provided at the entrance of the first device;

[0111] The first device is a security inspection device, and the second device is an identification scanning device;

[0112] Before obtaining the running distance of the object to be detected from the completion of the image information acquisition to the completion of the identification information acquisition, the method further includes:

[0113] The speed encoder is activated when the fourth photoelectric sensor is triggered by the object to be detected.

[0114] In this way, the speed encoder is only started when an object to be detected passes (ie, information collection and binding are required), and the speed encoder can be turned off when no object to be detected is transmitted, which is beneficial to saving energy consumption.

[0115] In the embodiment of the present application, the information binding method is also described in detail based on a specific application scenario. In this specific application scenario, the items to be inspected (i.e., express delivery) are sorted at the transfer site, and the security inspection equipment is set up in the middle of the sorting line (i.e., belt conveyor). The express delivery first passes through the single-piece separator to separate the express delivery that is closer to each other, so as to ensure that the express delivery passes through the security inspection equipment one by one in sequence.

[0116] When the photoelectric sensor at the entrance of the security inspection device is triggered, the security inspection device turns on the perspective image to take pictures. When the photoelectric sensor at the exit of the security inspection device is triggered, the photoelectric sensor is turned off to take pictures, thereby obtaining a security inspection image.

[0117] After passing through the security inspection equipment, after a preset distance (for example, 3 meters), it passes through the scanning equipment (for example, a six-sided scanning equipment). A photoelectric sensor is set at the entrance of the scanning equipment to sense the entry of the express delivery. When the photoelectric sensor is triggered, the waybill identification (for example, the waybill number) is obtained through the scanning equipment. In actual use, due to factors such as the different lengths of express parcels and the uncertain position of the cover sheet, the actual time for collecting and obtaining the waybill identification is not fixed.

[0118] Specifically, each photoelectric sensor can count and record the corresponding time when it senses an object passing by. In this way, the counting status of the four photoelectric sensors and the corresponding time information can be obtained, which can be matched with the corresponding image information or identification information to determine the collection time of the image information and the collection time of the identification information.

[0119] In one application scenario, the corrected standard distance is determined in the historical test phase. Specifically, the conveyor belt is turned on, and after stable operation, multiple express parcels (for example, 10) are placed. When an express parcel passes through the security inspection equipment entrance, security inspection equipment exit, scanning equipment entrance, and the photoelectric sensor at the scanning equipment exit is triggered, the running distance information of the speed encoder is obtained and recorded, and the number of triggering times of the photoelectric sensor is counted. Based on the running distance information corresponding to the 10 parcels, the average distance between each photoelectric sensor can be determined, thereby eliminating the calculation error corresponding to the speed encoder.

[0120] During the operation phase of formal information binding, each item to be detected is transmitted to the security inspection equipment and the scanning equipment in turn. When the photoelectric sensor at the entrance of the security inspection equipment is triggered, the corresponding distance calculation unit is triggered, and the corresponding distance information is obtained when each photoelectric sensor is triggered, so as to determine the corresponding running distance of the item to be detected according to the distance information fed back by the distance calculation unit and the speed encoder.
