When the virtual bearing object is displayed in the first virtual display space, the display position of the virtual bearing object can be determined in a mode of determining a target plane which actually exists in a real scene. Because the target plane in the real scene can be placed at any position, when the display position of the virtual bearing object is determined, the virtual bearing object does not need to be fixed on a certain display position for display, and the display is more flexible.

Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present disclosure more clear, the technical solutions of the embodiments of the present disclosure will be described clearly and completely with reference to the drawings in the embodiments of the present disclosure, and it is obvious that the described embodiments are only a part of the embodiments of the present disclosure, not all of the embodiments. The components of embodiments of the present disclosure, as generally described and illustrated herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present disclosure is not intended to limit the scope of the disclosure, as claimed, but is merely representative of selected embodiments of the disclosure. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the disclosure without making creative efforts, shall fall within the protection scope of the disclosure.

It has been found that when displaying digitized items, only purchased digitized items are typically displayed. When the digital articles are displayed, which digital article is specifically displayed is usually determined according to the selection of the user, so that the user can only view the digital articles one by one when viewing the digital articles, and therefore, less information can be displayed during the display.

Based on the research, the disclosure provides a display method, for digital articles owned by a user, the digital articles can be displayed together by using a displayed virtual carrier model on the displayed digital articles, so that the user can conveniently and intuitively check the digital articles synchronously, and the displayed information is more comprehensive.

In addition, various activation states are set for the digital articles, and the displayed virtual display model corresponds to different activation states during display, so that the current activation state characteristics of the digital articles can be displayed for the user by utilizing the displayed virtual display model, and the expressive information is richer.

The above-mentioned drawbacks are the results of the inventor after practical and careful study, and therefore, the discovery process of the above-mentioned problems and the solutions proposed by the present disclosure to the above-mentioned problems should be the contribution of the inventor in the process of the present disclosure.

It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined and explained in subsequent figures.

To facilitate understanding of the present embodiment, first, a display method disclosed in the embodiments of the present disclosure is described in detail, where an execution subject of the display method provided in the embodiments of the present disclosure is generally a computer device with certain computing capability, and the computer device includes, for example: augmented Reality (AR) devices, for example, may include head-mounted devices, mobile devices, and the like. In some possible implementations, the presentation method may be implemented by a processor calling computer readable instructions stored in a memory.

The following is a description of the display method provided by the embodiments of the present disclosure.

Referring to fig. 1, a flowchart of a display method provided in the embodiment of the present disclosure is shown, where the method includes steps S101 to S103, where:

s101: detecting the activation state corresponding to each owned digitalized object; the activation state includes at least one of: inactive, active, and activated;

s102: respectively displaying virtual display models respectively corresponding to the digital articles according to the activation states respectively corresponding to the digital articles in the virtual bearing article models displayed on the display interface;

s103: responding to the triggering operation of the virtual display model corresponding to the first target digitalized object, and acquiring and displaying introduction content information of the first target digitalized object based on the activation state corresponding to the first target digitalized object.

The following describes details of S101 to S103.

In the above S101, the digitalized article includes an article which is not physically and is expressed by a digital virtual representation. Taking the digital collection as an example, when viewing the digital collection, since the digital collection is not an entity, and data corresponding to the digital collection, such as an inhomogeneous token (or called an irreplaceable token) in a blockchain, or a returned hash value, cannot intuitively express appearance features of a picture, an instrument, and the like corresponding to the digital collection, a virtual special effect corresponding to the digital collection is viewed by means of a graphical display interface on a mobile device, or AR glasses, and the like, thereby assisting a user in viewing, purchasing, and the like the digital collection.

Where NFT is an entry of a blockchain, which is a decentralized digital ledger technique for cryptocurrency. Because NFT maps unique serial numbers on blockchains, its non-tamper, inseparable, and irreplaceable nature is suitable for use as a carrier of digitized items in transactions such as purchases, NFT may be used to represent a unique digitized item. When the user purchases and acquires ownership rights of the digital goods, the ownership records of the NFT corresponding to the digital goods are acquired.

The embodiment of the disclosure provides a display mode, which can display digital articles. Specifically, during the displaying, the virtual display model corresponding to the digitalized product may be displayed, or further, the introduction content information corresponding to the digitalized product may be displayed. The virtual display model may be displayed in an AR display manner, and the introduction content information may include, but is not limited to, text introduction information and image introduction information corresponding to the digital article, where the image introduction information may further include picture introduction information and video introduction information.

For example, the activation operation of the digital article may be included. The digitalized article is corresponding to different activation states at different stages of activation of the digitalized article, and the display information when the digitalized article is displayed at different activation states is also different, such as displaying different forms of virtual display models. Therefore, the displayed virtual display model can visualize the appearance related characteristics of the specifically displayed digital article on one hand, and can intuitively express the corresponding activation state of the digital article through different forms of virtual display models on the other hand.

In one possible scenario, in response to a user purchasing a digitized item on a purchase platform (e.g., purchasing software for the digitized item), the terminal device may determine that the user already owns the digitized item; at this time, the activation state corresponding to the digital article is not activated. The digitalized article may include a corresponding physical product, and the physical product may be a product corresponding to the digitalized article, for example, if the virtual display model corresponding to the digitalized article includes a lamb doll, the physical product may include a lamb doll. Alternatively, the physical product may be a certificate board, on which information such as the name of the digital article may be recorded to correspond to the digital skin. In physical products, for example, Near Field Communication (NFC) chips are carried or embedded, and NFC identifiers corresponding to digitalized products are stored in the NFC chips.

After receiving the physical product, the user can identify the NFC chip by using the mobile phone. After the computer equipment capable of identifying the NFC chip such as the mobile phone is close to the NFC chip in the physical product, the NFC identification corresponding to the digital product can be read from the NFC chip. In one possible case, the activation process may be performed on the digital item if the NFC identifier of the digital item is sensed to be inactive. That is to say, if it is determined that the activation state of the corresponding digital item is not the inactivated state after the NFC identifier is read, the activation processing is not performed on the digital item corresponding to the NFC identifier, that is, the activation processing is not repeated on the digital item that has been subjected to the activation processing, so as to reduce the occurrence of an error in changing the activation state of the digital item.

Thus, for each digital article owned by the user, according to the above-described activation processing manner, it can be known that the activation state corresponding to each digital article may include an inactivated state, that is, the NFC identifier corresponding to the digital article is not recognized; the state during activation, namely the state of intermediate transition when the activation state is not converted into the activation state after the NFC identification corresponding to the digital article is identified; and an activated state, i.e., a resultant state after activation of the digitized item is completed.

For the above S102, after the activation state corresponding to each digital article is determined according to the above S101, the virtual display models corresponding to each digital article can be displayed together in the virtual carrier model displayed on the display interface. And determining the virtual model corresponding to each digital article according to the activation state corresponding to the digital article. Specifically, when any digitalized article is activated, the activation states corresponding to different time nodes of the digitalized article in different activation processes can be determined according to the progress of the activation process, and the display state of the virtual display model of the digitalized article is correspondingly adjusted according to the activation states corresponding to the different time nodes.

For example, after the activation of the digital item is completed, the virtual display model corresponding to the digital item may be updated to the activated display state.

In the specific implementation, after the digital goods owned by the user are confirmed, the virtual display model corresponding to the digital goods can be displayed. In order to correspondingly express different activation states of the digital article by using the virtual display model, when determining the corresponding virtual display model for the digital article, the following method may be specifically adopted:

(a1) the method comprises the following steps In response to the activation status of the corresponding digital item including non-activation, the virtual display model of the corresponding digital item includes at least one of: the digital goods display system comprises a first virtual model of the digital goods in an inactivated state and activated state indication information corresponding to the first virtual display model.

In this way, the activation state corresponding to the digitalized article is an inactivated state, in which case the first virtual model corresponding to the digitalized article can be displayed with a gray, non-clickable effect because it is also necessary to wait for a subsequent activation process. Exemplarily, referring to fig. 2, a schematic diagram of a first virtual model provided in the embodiment of the present disclosure is shown. Wherein, taking the first virtual model shown in fig. 2 (a) as an example, the first virtual model displays a doll figure corresponding to the digital item and appears gray to indicate that the corresponding digital item is currently in an inactivated activated state.

In addition, the first virtual model may further include activation state indication information corresponding to the first virtual presentation model. The activation state indication information may be represented by text, for example, the activation state indication information 21 shown in fig. 2 (a) in text form; alternatively, it may be represented in the form of a virtual effect, such as virtual effect 22 shown in FIG. 2(b) wrapped around the doll image. The display form of the activation status indication information is not limited in the embodiments of the present disclosure.

(a2) The method comprises the following steps In response to the activation state corresponding to the digital article being included in the activation, the virtual display model corresponding to the digital article includes at least one of: the second virtual model of the digital article in the activated state and the activation state indication information corresponding to the second virtual display model.

In this way, the activation state corresponding to the digitalized article is an activated state, in which case the digitalized article is being activated but the activated state is not reached, so that the second virtual display model corresponding to the digitalized article can be displayed in the activated state, for example, a progress bar showing the activation is superimposed on the second virtual display model. Exemplarily, referring to fig. 3, a schematic diagram of a second virtual model provided in the embodiment of the present disclosure is shown. The display progress of the progress bar 31 may be determined according to the actual progress in the activation, and details are not repeated here. In addition, the activation state indication information corresponding to the second virtual representation model may be represented in a form similar to the above (a1) by using a representation character form or a virtual special effect, and fig. 3 specifically illustrates the activation state indication information 32 in a character form.

(a3) The method comprises the following steps In response to the activation status corresponding to the digital item comprising activated, the virtual display model corresponding to the digital item comprises at least one of: the third virtual model of the digitalized article in the activated state, the detail viewing button corresponding to the third virtual model and the activation state indication information corresponding to the third virtual model.

In this manner, the activation state corresponding to the digitalized article is an activated state, and in this state, the digitalized article is completely activated, so that the corresponding third virtual model can be completely displayed. Exemplarily, referring to fig. 4, a schematic diagram of a third virtual model provided in the embodiment of the present disclosure is shown. In contrast to the first virtual display model corresponding to the digitized item shown in fig. 2 in the inactivated state and the second virtual display model corresponding to the digitized item shown in fig. 3 in the activated state, the third virtual display model shown in fig. 4 is displayed in a complete and unobstructed manner to represent that the digitized item has been activated.

In addition, when the activation state indicating information corresponding to the third virtual model is displayed, the activation state indicating information 41 shown in fig. 4, for example, may be displayed in a text form below the third virtual model so as not to obscure the display of the third virtual model. Alternatively, a highlight special effect may be further added to the third virtual model. And for the activated third virtual model, a detail viewing button is correspondingly included, and the detail viewing button may be shown in a form of a visual key, or the third virtual model itself may be used as a detail viewing button that can be clicked to trigger, so that when the user clicks to trigger the third virtual model, the detail viewing button of the corresponding digital article may be triggered.

The triggering of the detail viewing button and the subsequent viewable detail information are explained below, and are not repeated herein.

In another embodiment of the present disclosure, in order to collectively display each digital article, in the embodiment of the present disclosure, a virtual carrier model is displayed in a display interface, and each digital article is displayed in the virtual carrier model through a corresponding virtual display model. The presentation interface may include, for example, a graphical display interface connected to a computer device, such as a device screen of a mobile device, or a display screen of AR glasses.

Here, the virtual carrier model is a virtual model; the virtual bearing object is, for example, a virtual display cabinet or a virtual shelf; when the virtual carrier is displayed on the display interface, the virtual carrier model can also display the virtual display models respectively corresponding to the digital articles so as to embody the functional characteristics that the virtual carrier model can store the digital articles. Illustratively, referring to fig. 5, a schematic diagram of displaying a virtual carrier model on a display interface according to an embodiment of the present disclosure is provided; the virtual carrier model 51 shown therein shows in particular the style of a display case.

In specific implementation, when the virtual carrier model is displayed on the display interface, the modes that can be adopted include, but are not limited to, the following two modes (b1) and (b 2):

(b1) the method comprises the following steps Acquiring a real scene image, and identifying a target marker in the real scene image; the target marker comprises a positioning marker; generating a first virtual display space for displaying the virtual carrier model and a first display position of the virtual carrier model in the first virtual display space based on the position of the target marker in the real scene image; rendering the virtual carrier model in the first virtual display space based on the first display position so as to display the virtual carrier model on the display interface.

Next, a part of the concept involved in the above-described mode (a) will be explained first.

The target marker comprises a marker which exists in a real scene and can be used for positioning the position of the virtual carrier model when the augmented reality display is carried out. In particular, the target identifier may comprise a location identifier marker. When acquiring the image of the real scene, for example, a camera carried by the augmented reality device or associated with the augmented reality device may be used to acquire the image of the real scene, and identify the target marker actually existing in the real scene from the acquired image of the real scene.

The position of the target marker in the image of the real scene, that is, the specific area where the target marker is located in the image of the real scene.

The first virtual display space comprises a virtual three-dimensional display space required by the virtual carrier model when the virtual carrier model is displayed in an augmented reality mode. The first virtual display space corresponds to a real scene, first display content information corresponding to a virtual carrier model is rendered in the first virtual display space and is displayed in an overlapped mode in the collected real scene image, and therefore the effect displayed in real time in the collected real scene image by the first display content information can be displayed, and the effect of augmented reality is achieved.

The implementation method includes the steps that a Marker which is manufactured in advance is needed (for example, a template card or a two-dimensional code with a certain specification and shape is drawn), then the Marker is placed at a position in reality, which is equivalent to the determination of a plane in a real scene, then a camera is used for identifying and evaluating the position of the Marker (position Estimation), the position of the Marker is determined, then a coordinate system with the center of the Marker as an origin is called a template coordinate system (Marker Coordinates), namely a coordinate system corresponding to a first virtual display space, a transformation is obtained so that a mapping relation is established between the template coordinate system and a screen coordinate system, and based on the mapping relation and the position of the Marker in a real scene image, a first display position of first display content information in the first virtual display space can be determined. Then, by using the first display position, the virtual carrier model can be displayed at the first display position, and the image displayed after rendering on the screen can display the effect that the virtual carrier model is related and displayed on the plane where the marker is located.

Here, since the virtual carrier model is expected to express an effect similar to that of a real scene as a digital object capable of storing different digital objects on the display interface, it is preferable that the virtual carrier model is displayed on a plane when the display position of the virtual carrier model is determined. And marker itself can print on the paper promptly when printing, and the plane that such paper corresponds in first virtual show space also can be regarded as corresponding to the show plane that can place showcase etc. in the real scene.

After the real scene image is acquired, on one hand, the position of the target marker in the real scene image can be determined, and on the other hand, the target marker can be identified so as to display the virtual bearing object model.

After the position of the target marker in the image of the real scene is determined, a first virtual display space of the virtual carrier model can be determined. Taking a marker as an example, when the marker is used for displaying the virtual bearing object model, the three-dimensional virtual model is displayed above the marker, so that when the first virtual display space is determined, for example, a plane where tickets printed with the marker are located is a plane where an x axis and a y axis are located, and a normal vector perpendicular to the plane where the marker is located is taken as a z axis, so as to establish a three-dimensional space. When the first display position when the virtual carrier model is displayed in the first virtual display space is determined, for example, a position in the positive direction of the z-axis, for example, 50 cm in the positive direction of the z-axis, may be selected as the first display position, that is, the virtual carrier model is placed 50 cm above the marker for display. Thus, the display can be carried out at a comfortable angle when being watched by human eyes.

In addition, in one possible scenario, the target marker may move in the real scene following the object on which it is resting. For example, when a marker is printed on the certificate board described in S101, if the hand-held certificate board moves, the marker printed on the certificate board also moves accordingly. Therefore, when the first virtual exhibition space is determined, the determination is performed according to the position of the marker, but not according to the image of the real scene.

(b2) The method comprises the following steps Acquiring a real scene image, reconstructing a three-dimensional scene based on the real scene image, and generating a second virtual display space for displaying the virtual carrier model; determining a second display position of the virtual carrier model in the second virtual display space based on a position of a target plane included in the real scene image; rendering the virtual carrier model in the second virtual display space based on the second display position so as to display the virtual carrier model on the display interface.

The second virtual display space has a similar purpose to the first virtual display space and comprises a virtual three-dimensional display space required by the virtual carrier model when displayed in an augmented reality mode.

The object plane included in the image of the real scene is, for example, a plane that can be displayed in the image of the display scene, and may be, for example, an object recognized after the image of the real scene is recognized, the object having a plane that can be recognized, for example, a table, and a surface of the table may be recognized as the object plane. The position of the object plane in the image of the real scene, that is, the specific region where the object plane is located in the image of the real scene.

In particular, in real time, when a real scene image is acquired And a three-dimensional scene is reconstructed based on the real scene image, for example, a camera coordinate system may be determined in a manner of simultaneously positioning And Mapping (SLAM), And a second virtual display space may be established based on the camera coordinate system, so that a three-dimensional structure may be restored from two-dimensional images without determining information of the three-dimensional space in advance, And then the map may be continuously tracked And expanded, which may ensure that the second virtual display space may be established in real time according to a photographed real scene image when a virtual carrier model is displayed. Therefore, the virtual carrier model can be rendered in the second virtual display space and displayed in the acquired real scene image in an overlapping mode, and the effect of augmented reality is achieved.

In addition, when the virtual carrier model is displayed, since the second virtual display space may correspond to a space displayed by the image of the real scene, the target plane may also determine a corresponding virtual plane in the second virtual display space and a position of the virtual plane in the second virtual display space, that is, a second display position. Here, it may be determined that the virtual bearer model is to be presented on a virtual plane of the second virtual presentation space, the virtual plane being in particular at a second presentation position of the second virtual presentation space. In a possible case, in order to easily determine the second display position for displaying the first display content information, the target plane included in the real scene image may be determined in an object recognition manner, the second display position of the virtual plane corresponding to the target plane in the second virtual display space is determined according to the position of the target plane in the real scene image, and then the virtual carrier model is displayed on the virtual plane located at the second display position. Like this, when showing virtual carrier model, can cooperate the target plane in the reality scene to show, the authenticity when showing first show content that can further improvement.
