Description

Technical Field

[0001] This invention relates to the field of express delivery technology, and in particular to a method, apparatus, electronic device, and storage medium for generating images of items. Background Technology

[0002] In the express delivery pickup process, traditional methods rely on manual entry of waybill information and inspection of goods, which is inefficient and prone to errors. For example, manual operation may result in data entry errors or oversights in goods inspection, leading to obstacles in subsequent sorting and transportation. Furthermore, during delivery, damage to packages is difficult to determine effectively, and there is no way to prove when the damage occurred. This makes it difficult for merchants, express delivery companies, and consumers to identify the cause of the problem, ultimately reducing the consumer experience. Summary of the Invention

[0003] This invention provides a method, apparatus, electronic device, and storage medium for generating images of items, in order to solve the problem of being unable to trace the stage of damage when a package is damaged.

[0004] According to one aspect of the present invention, a method for generating an image of an object is provided, the method comprising:

[0005] The first image is defined as an image taken of the outer surface of the mailed item.

[0006] Determine the current courier delivery stage of the mailed item, and based on the current courier delivery stage of the mailed item, determine the first template, which is an image watermark generation template;

[0007] Based on the first template, determine the first information, and generate the first watermark based on the first information and the first template. The first information is the information that needs to be filled in the first template. The first information includes at least the unique identifier of the mailed item, the time when the first image was taken, and the location of the mailed item.

[0008] Add the first watermark to the first image to obtain the second image.

[0009] According to another aspect of the present invention, an object image generation apparatus is provided, the apparatus comprising:

[0010] The first image determination module is used to determine a first image, which is an image of the outer surface of the mailed item.

[0011] The first template determination module is used to determine the current express delivery stage of the mailed item and determine the first template based on the current express delivery stage of the mailed item. The first template is an image watermark generation template.

[0012] The first watermark generation module is used to determine first information based on the first template, and generate a first watermark based on the first information and the first template. The first information is the information that needs to be filled in the first template. The first information includes at least the unique identifier of the mailed item, the time when the first image was taken, and the location of the mailed item.

[0013] The second image generation module is used to add the first watermark to the first image to obtain the second image.

[0014] According to another aspect of the present invention, an electronic device is provided, the electronic device comprising:

[0015] At least one processor; and

[0016] A memory that is communicatively connected to at least one processor; wherein,

[0017] The memory stores a computer program that can be executed by at least one processor, such that the at least one processor is able to perform the article image generation method of any embodiment of the present invention.

[0018] According to another aspect of the present invention, a computer-readable storage medium is provided, which stores computer instructions for causing a processor to execute and implement the article image generation method of any embodiment of the present invention.

[0019] The technical solution of this invention involves determining a first image, which is an image of the outer surface of a mailed item; determining the current express delivery stage of the mailed item; and determining a first template, which is an image watermark generation template, based on the current express delivery stage. This method can quickly and accurately determine the template required for the current stage, thereby reducing template generation and selection time and accelerating the mailing efficiency. Furthermore, obtaining the first template through this method avoids problems such as information omissions during subsequent information filling. Based on the first template, first information is determined, and a first watermark is generated based on the first information and the first template. The first information is the information to be filled in the first template. The first watermark is added to the first image to obtain a second image. This ensures that the generated second image contains the unique identifier of the mailed item, the time the first image was taken, and the location of the mailed item. Since the first image includes the outer surface of the mailed item, the second image will also include the outer surface of the mailed item. This allows the condition of the outer surface of the mailed item at the time the first image was taken and the location of the mailed item to be determined based on the second image, thus serving as explanatory evidence in case of disputes.

It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] Example 1

[0029] Figure 1 This is a flowchart illustrating a method for generating an image of an item, as provided in Embodiment 1 of the present invention. This embodiment is applicable to situations where damage to a package is recorded during express delivery and used as evidence in case of disputes. The method can be executed by an item image generating device, which can be implemented in hardware and / or software and can be configured in an electronic device with data processing capabilities. Figure 1 As shown, the method includes:

[0030] S110. Determine the first image, which is an image taken of the outer surface of the mailed item.

[0031] During the courier pickup or delivery process, a smart device is used to capture an image of the outer surface of the mailed item. The smart device can be any of the following: mobile phone, camera, scanner, tablet computer, etc.

[0032] The first image can be the outer surface of the mailed item itself; or the outer surface of the packaged mailed item; or a composite image of the outer surface of the mailed item itself and the outer surface of the packaged mailed item.

[0033] S120. Determine the current express delivery stage of the mailed item, and determine the first template based on the current express delivery stage of the mailed item. The first template is an image watermark generation template.

[0034] The express delivery stage can be the current stage in the express delivery process of a mailed item. The current express delivery stage can be one of the candidate express delivery stages. These candidate stages include the pickup stage, the receiving stage at the express station, the transfer stage at the express station, and the delivery stage. Specifically, the receiving stage at the express station involves the express station receiving the mailed item; the transfer stage at the express station involves the express station forwarding the mailed item to other express stations.

[0035] Since the information required at different stages of express delivery may vary, different image watermark generation templates can be generated for each stage. These templates are then used accordingly, and the initial template is determined based on the current stage of the delivery process.

[0036] By determining the current courier delivery stage of the mailed item and identifying the first template based on that stage, the required template for the current stage can be determined quickly and accurately. This reduces the time spent generating and selecting templates, thereby accelerating the mailing efficiency. Furthermore, obtaining the first template through this method can prevent issues such as missing information during subsequent information filling.

[0037] In one alternative approach, a first template is determined based on the current courier delivery stage of the mailed item, including steps A1-A2:

[0038] Step A1: Obtain a pre-generated template table, which includes at least one candidate express delivery stage and a second template corresponding to each candidate express delivery stage.

[0039] Step A2: Based on the current courier delivery stage of the mailed item, filter the template table to obtain the first template. The first template is the second template in the template table that corresponds to the current courier delivery stage.

[0040] When determining the first template, it is necessary to first obtain a pre-determined template table, which contains at least one candidate express delivery stage and a second template corresponding to each candidate express delivery stage. Based on the express delivery stage of the current stage, the candidate express delivery stage that is the same as the current express delivery stage is found in each candidate express delivery stage, and the second template corresponding to the candidate express delivery stage is used as the first template.

[0041] By obtaining a pre-generated template table, which includes at least one candidate express delivery stage and a second template corresponding to each candidate express delivery stage, and filtering the template table according to the express delivery stage of the mailed item at the current moment, a first template is obtained. The first template is the second template in the template table that corresponds to the express delivery stage at the current moment. This enables the rapid determination of the first template, thereby avoiding the computational burden of regenerating the first template.

[0042] In one alternative approach, a pre-generated template table is obtained, including steps B1-B2:

[0043] Step B1: If the template table is being retrieved for the first time, a template table request is sent to the backend server. The template table request is used to request the template table from the backend server.

[0044] Step B2: Receive the template table sent by the backend server and store the template table in memory space.

[0045] Because there are too many smart devices that need to be identified in the template table, the method of determining them offline in a unified manner is too complicated and it is difficult to achieve unified updates for each smart device in subsequent updates.

[0046] Therefore, this application transmits the template table by communicating with the smart device through the backend server. When the information in the template table is updated in the future, only the template table in the backend server needs to be updated, and the backend server will transmit it to each smart device, thereby realizing the updating and iteration of the template table.

[0047] For smart devices, when they first request the template table, they need to send a template table request to the backend server to inform the smart device that it needs the template table. After receiving the template table request, the backend server will send the latest template table to the smart device.

[0048] After the template table on the backend server is updated, the updated content will be determined and pushed to various smart devices.

[0049] After receiving updated content, if the smart device needs to update, it sends a template table request to the backend server to obtain a new template table.

[0050] In addition, if the first template is not being retrieved for the first time, the template table is retrieved from the memory space.

[0051] By determining whether the template table is being retrieved for the first time, and if so, sending a template table request to the backend server, receiving the template table from the backend server, and storing the template table in memory, the system achieves the initial retrieval of the template table. This allows subsequent uses of the template table to be retrieved directly from memory, thereby reducing the number of accesses to the backend server and reducing its operational load.

[0052] S130. Based on the first template, determine the first information, and generate the first watermark based on the first information and the first template. The first information is the information that needs to be filled in the first template. The first information includes at least the unique identifier of the mailed item, the time when the first image was taken, and the location of the mailed item.

[0053] After obtaining the first template, it is possible to determine the first information required to generate the corresponding first watermark based on the first template, and generate the first watermark based on the first information and the first template. The first information must at least include the unique identifier of the mailed item, the time the first image was captured, and the location of the mailed item. The first watermark also includes the unique identifier of the mailed item, the time the first image was captured, and the location of the mailed item.

[0054] Furthermore, the first information required for generating the first watermark in the second template can differ depending on the stage of the express delivery process. For example, when signing for a package, the recipient's signature and any supporting documents provided by the signatory can be used as the first information. The first information can be set according to the actual situation.

[0055] S140. Add the first watermark to the first image to obtain the second image.

[0056] By adding a first watermark to a first image to obtain a second image, the generated second image can contain the unique identifier of the mailed item, the time the first image was taken, and the location of the mailed item. Since the first image includes the outer surface of the mailed item, the second image will also include the outer surface of the mailed item. This allows the condition of the outer surface of the mailed item at the time the first image was taken and the location of the mailed item to be determined based on the second image, thus serving as explanatory evidence in the event of a dispute.

[0057] In one alternative approach, after adding the first watermark to the first image to obtain the second image, steps C1-C3 are further included:

[0058] Step C1: Determine the binary byte stream corresponding to the second image.

[0059] Step C2: Calculate the first hash value by processing the binary byte stream according to the Message Digest Algorithm Version 5.

[0060] Step C3: Store the first hash value and the second image.

[0061] To ensure the second image cannot be tampered with by software, after its generation, a first hash value is calculated from the corresponding binary byte stream using the Message Digest Algorithm Version 5 (CDE5). This hash value, along with the second image, is then stored. This allows for the determination of whether the second image has been tampered with by comparing the two hash values ​​if the tampering is suspected, thus improving the authenticity of the second image.

[0062] The technical solution of this application involves determining a first image, which is an image of the outer surface of a mailed item; determining the current express delivery stage of the mailed item; and determining a first template, which is an image watermark generation template, based on the current express delivery stage. This allows for quick and accurate determination of the template required for the current stage, reducing template generation and selection time and accelerating the mailing efficiency. Furthermore, obtaining the first template through this method avoids issues such as missing information during subsequent information filling. Based on the first template, first information is determined, and a first watermark is generated based on the first information and the first template. The first information is the information required to be filled in the first template. The first watermark is added to the first image to obtain a second image. This second image contains the unique identifier of the mailed item, the time the first image was taken, and the location of the mailed item. Since the first image includes the outer surface of the mailed item, the second image will also include the outer surface of the mailed item. This allows the condition of the outer surface of the mailed item at the time the first image was taken and the location of the mailed item to be determined based on the second image, thus serving as explanatory evidence in case of disputes.

[0063] Example 2

[0064] Figure 2 This invention provides a flowchart of another method for generating an object image. Based on the above embodiments, this embodiment further optimizes the process of adding a first watermark to a first image to obtain a second image. This embodiment can be combined with various optional solutions in one or more of the above embodiments. Figure 2 As shown, the item image generation method of this embodiment may include the following steps:

[0065] S210. Determine the first image, which is an image taken of the outer surface of the mailed item.

[0066] S220. Determine the current express delivery stage of the mailed item, and determine the first template based on the current express delivery stage of the mailed item. The first template is an image watermark generation template.

[0067] S230. Based on the first template, determine the first information, and generate the first watermark based on the first information and the first template. The first information is the information that needs to be filled in the first template. The first information includes at least the unique identifier of the mailed item, the time when the first image was taken, and the location of the mailed item.

[0068] S240. Encrypt the first watermark according to the preset encryption algorithm to obtain the second information.

[0069] S250. Based on the second information, generate a second watermark and add the second watermark to the first image to obtain the second image.

[0070] In addition to calculating the hash value of the second image as provided in the above embodiments, the first watermark can also be encrypted to obtain the second information. Then, when generating the second image subsequently, the second information is used to generate a second watermark, which is then added to the first image to obtain the second image.

[0071] Encrypting the first piece of information can improve the privacy of the second image, thereby ensuring the security of the express delivery information.

[0072] By adopting the technical solution of this application, the first watermark is encrypted according to a preset encryption algorithm to obtain the second information, the second watermark is generated according to the second information, and the second watermark is added to the first image to obtain the second image. This can improve the privacy level of the second image and thus ensure the security of express delivery information.
