[0024] It should be noted that the relevant information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data for display, data for analysis, etc.) involved in this disclosure are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data comply with the relevant laws, regulations and standards of the relevant regions. For example, an interface is set up between this system and the relevant users or organizations. Before obtaining relevant information, it is necessary to send an acquisition request to the aforementioned user or organization through the interface, and obtain relevant information after receiving the consent information fed back by the aforementioned user or organization.

[0025] The present invention is described below in conjunction with preferred implementation steps. Figure 1 is a flow chart of a transaction method provided according to an embodiment of the present application, such as Figure 1 As shown, the method comprises the following steps:

[0026] Step S101, obtaining a commodity model, wherein the commodity model is a three-dimensional model of the transaction commodity provided by the commodity supplier.

[0027] In this step, the execution entity may be a trading platform. The product model refers to a three-dimensional model of the trading product provided by the product supplier for trading. Compared with photos and text, the three-dimensional model can show the appearance and structure of the product more realistically and three-dimensionally, which helps the buyer to understand the product more accurately. Through the three-dimensional model, the buyer can understand the product more intuitively and make more accurate purchase decisions, which also helps to reduce transaction disputes caused by information asymmetry.

[0028] Step S102: sending the product model to the product buyer, and receiving the first transaction intention of the product buyer for the transaction product.

[0029] In this step, after obtaining the 3D model of the product, the trading platform will send the model to the buyer of the product. The buyer can get a more comprehensive understanding of the product by viewing the 3D model, which helps the buyer make a more accurate purchase decision. After viewing the 3D model of the product, the buyer will express their initial intention for the transaction product based on their own needs and judgment, that is, the first transaction intention.

[0030] Step S103, when the buyer of the first transaction intention representation commodity confirms that the transaction object is the transaction commodity, a transaction based on the transaction commodity is conducted between the commodity supplier and the commodity buyer.

[0031] In this step, if the buyer's first transaction intention indicates that they confirm that the transaction object is this product, then the actual transaction will begin. After both the supplier and the buyer confirm the transaction, the two parties will perform specific transaction operations based on this product, such as negotiating the price, quantity, payment method, etc., and finally complete the transaction.

[0032] Optionally, in the transaction method provided in the embodiment of the present application, the method also includes: forwarding the first transaction intention to the commodity supplier when the first transaction intention includes the commodity purchaser's modification opinions on the transaction commodity; receiving the modified commodity model sent by the commodity supplier, wherein the modified commodity model is a model obtained by the commodity supplier modifying the commodity model based on the first transaction intention; sending the modified commodity model to the commodity purchaser, and receiving the commodity purchaser's second transaction intention for the modified commodity model; until receiving the transaction intention indicating that the commodity purchaser confirms that the transaction object is the transaction commodity obtained by N times modification, a transaction based on the transaction commodity obtained by N times modification is conducted between the commodity supplier and the commodity purchaser, wherein N is an integer greater than 1.

[0033] Optionally, when the commodity purchaser has modification opinions on the transaction commodity, the two parties can communicate repeatedly to reach a mutually satisfactory transaction status and finally complete the transaction process. After the commodity purchaser has viewed the commodity model, they may put forward some modification opinions and hope that the commodity supplier can modify the commodity model according to these opinions. These modification opinions may involve the appearance, size, color and other aspects of the commodity. When the commodity purchaser puts forward modification opinions, these opinions (i.e., the first transaction intention) will be forwarded to the commodity supplier by the transaction platform. The supplier will make corresponding adjustments to the commodity model based on these opinions.

[0034] According to the modification suggestions of the commodity buyer, the commodity supplier will modify the commodity model and send the modified commodity model to the buyer. In this way, the buyer can view the effect of the modification and decide whether further adjustments are needed. After viewing the modified commodity model, the buyer will give their feedback, that is, the second transaction intention. This feedback may be a confirmation of the modification effect or a new modification suggestion. The above modification and feedback process may be repeated many times. The buyer and the supplier will continue to exchange opinions and modified commodity models until a transaction commodity that both parties are satisfied with is found.

[0035] When the commodity buyer finally confirms that the transaction object is the transaction commodity obtained after N modifications (where N is an integer greater than 1), the commodity supplier and the buyer will conduct actual transactions based on this modified commodity model. This modification and feedback mechanism based on the three-dimensional model helps to improve the efficiency and success rate of transactions and reduce transaction disputes caused by information asymmetry or misunderstanding.

[0036] Optionally, in the transaction method provided in the embodiment of the present application, a product model is sent to a product purchaser, and a first transaction intention of the product purchaser for the transaction product is received, including: sending the product model to the product purchaser; displaying the product model in a virtual scene where a virtual image corresponding to the product purchaser is located, wherein the product purchaser determines the first transaction intention based on the product model in the virtual scene, and submits the first transaction intention to the transaction platform; and receiving the first transaction intention of the product purchaser for the transaction product.

[0037] Optionally, during the commodity transaction process, the transaction platform may be a platform that can provide users with a virtual scene, and users can log in to the virtual scene provided by the transaction platform with a virtual image. In this case, the commodity model can be displayed in the virtual scene where the buyer's virtual image is located. This display method enables the buyer to view the commodity in an environment that is closer to the real world, enhancing interactivity and immersion.

[0038] After viewing the product model in the virtual scene, the buyer will determine whether he is interested in the product based on his preferences, needs, price and other factors, determine the first transaction intention, and submit it to the trading platform. The trading platform will record this intention and send it to the supplier. The supplier receives the buyer's first transaction intention through the trading platform. This intention will tell the supplier the buyer's initial attitude and opinion on the traded product, and the supplier can make corresponding reactions or decisions based on this intention. The above process makes full use of the advantages of virtual scenes and three-dimensional models, making commodity transactions more intuitive, interactive and efficient. Buyers can truly feel the products in the virtual scene, and suppliers can quickly obtain feedback and intentions from buyers, thereby better meeting market demand.

[0039] Optionally, in the transaction method provided in the embodiment of the present application, obtaining a product model includes: obtaining scanning data of the transaction product; extracting point cloud data of the surface of the transaction product based on the scanning data; constructing a mesh model of the transaction product based on the point cloud data; adding texture features to the mesh model to obtain the product model, wherein the texture features are used to display the color and material of the transaction product.

[0040] Optionally, the commodity supplier can first make the actual commodity, and then generate the commodity model based on the actual commodity. After the commodity supplier makes the actual commodity, it can obtain the three-dimensional scanning data of the transaction commodity by using a specific scanning device (such as a three-dimensional scanner). After obtaining the scanning data, the point cloud data of the commodity surface can be extracted from these data. The point cloud data is composed of a large number of three-dimensional points, and each point represents a specific location on the surface of the commodity. These point cloud data are very dense and can accurately describe the shape of the commodity. With the point cloud data, you can start to build a mesh model of the commodity. The mesh model is composed of a series of triangular facets, which form the surface of the commodity by connecting the points in the point cloud data. The mesh model can more smoothly represent the shape of the commodity and facilitate subsequent editing and processing.

[0041] Although the mesh model can represent the shape of the product, it lacks visual information such as color and material. Therefore, it is necessary to add texture features to the mesh model. Texture features are usually achieved by mapping, that is, mapping one or more pictures (texture maps) onto the surface of the mesh model. These texture maps contain information such as the color and material of the product, making the product model more realistic when displayed. The final product model not only has an accurate shape, but also can show detailed features such as the color and material of the traded product.

[0042] Optionally, in the transaction method provided in the embodiment of the present application, when the first transaction intention represents that the commodity purchaser confirms that the transaction object is the transaction commodity, a transaction based on the transaction commodity is conducted between the commodity supplier and the commodity purchaser, including: sending the commodity model to the commodity purchaser and the commodity supplier respectively, wherein the commodity purchaser and the commodity supplier sign the commodity model respectively; receiving a first signature result of the commodity purchaser for the commodity model and a second signature result of the commodity supplier for the commodity model, and storing the first signature result and the second signature result in the blockchain; receiving transaction information sent by the commodity supplier or the commodity purchaser, and executing a transaction based on the transaction commodity.

[0043] Optionally, in a transaction based on a commodity model, after the commodity buyer confirms that the transaction object is a specific transaction commodity, the commodity model will be sent to the commodity buyer and the commodity supplier respectively to ensure that both parties can obtain an accurate model of the transaction commodity. Then, the commodity buyer and the commodity supplier will sign the commodity model. Signing is a verification and confirmation process, indicating that both parties agree that the model is the basis for the transaction. This increases the security of the transaction and prevents the model from being tampered with or replaced. After the signature is completed, the first signature result of the commodity buyer and the second signature result of the commodity supplier will be sent to the blockchain for storage. Blockchain is a distributed database that is tamper-proof and highly secure. Storing the signature results in the blockchain can ensure the authenticity and integrity of these results and prevent any party from denying or tampering with the signature afterwards.

[0044] After the signature result is stored in the blockchain, the transaction can officially begin. This process may include receiving transaction information sent by the supplier or buyer of the goods, such as price, quantity, payment method, etc. Based on this transaction information, the trading platform will perform corresponding transaction operations to ensure that both parties conduct transactions in accordance with the agreed conditions. Through the above process, both parties can trade goods in a safe, transparent and traceable environment. The application of blockchain technology makes transaction data more reliable and secure, and the signature mechanism ensures the recognition and consent of both parties to the transaction. Such a transaction process helps reduce fraud and disputes and improve the efficiency and trust of transactions.

[0045] Optionally, in the transaction method provided in the embodiment of the present application, transaction information sent by a commodity supplier or a commodity buyer is received, and a transaction based on the transaction commodity is executed, including: receiving a first synchronous transaction event sent by the commodity supplier according to the transaction information, wherein the commodity supplier calls a smart contract on the blockchain to execute the transaction to generate a first synchronous transaction event, and the first synchronous transaction event is used to indicate that the commodity supplier has executed the transaction; receiving a second synchronous transaction event sent by the commodity buyer according to the transaction information, wherein the commodity buyer calls a smart contract on the blockchain to execute the transaction to generate a second synchronous transaction event, and the second synchronous transaction event is used to indicate that the commodity buyer has executed the transaction; upon receiving the first synchronous transaction event and the second synchronous transaction event, determining that the transaction execution is completed.

[0046] Optionally, in a blockchain-based transaction process, a synchronous transaction event can be generated through a smart contract to confirm the completion of the transaction. Specifically, based on the transaction information, the commodity supplier will start to execute the transaction. In the process of executing the transaction, the supplier will call the smart contract on the blockchain. A smart contract is an automatically executed contract that will perform corresponding operations according to the written rules as long as the preset conditions are met. When the supplier successfully executes the transaction through the smart contract, a first synchronous transaction event will be generated. The main function of this event is to indicate to all relevant parties (including the buyer and the trading platform) that the supplier has executed the transaction in accordance with the agreed conditions. Similarly, based on the transaction information, the commodity buyer will also start to execute the transaction. The buyer will also call the same smart contract on the blockchain to execute the transaction. When the buyer successfully executes the transaction through the smart contract, a second synchronous transaction event will be generated. The function of this event is to indicate to all relevant parties that the buyer has also executed the transaction in accordance with the agreed conditions. In the blockchain system, only when the trading platform receives the first synchronous transaction event and the second synchronous transaction event at the same time, it will be determined that the transaction has been executed. This means that both the supplier and the buyer have completed their transaction obligations in accordance with the provisions of the smart contract. In this way, smart contracts ensure the automatic execution and synchronization of transactions, which greatly improves the efficiency and trust of transactions and reduces transaction disputes caused by human factors.

[0047] The transaction method provided in the embodiment of the present application obtains a product model, wherein the product model is a three-dimensional model of the transaction product provided by the product supplier; sends the product model to the product buyer, and receives the first transaction intention of the product buyer for the transaction product; and conducts a transaction based on the transaction product between the product supplier and the product buyer when the first transaction intention indicates that the product buyer confirms that the transaction object is the transaction product, thereby achieving the purpose of the user determining whether to conduct a transaction based on the three-dimensional model of the product, and solving the technical problem in the related art that the user may encounter products that do not conform to the description due to the use of photos and texts to describe the products during online transactions in the related art, thereby achieving the technical effect of enhancing the realism of online transactions and improving user experience.

[0048] It should be noted that the steps shown in the flowcharts of the accompanying drawings can be executed in a computer system such as a set of computer executable instructions, and that, although a logical order is shown in the flowcharts, in some cases, the steps shown or described can be executed in an order different from that shown here.
