Description

Method and system for realizing third-person perspective by using virtual objects

The description discloses a method for browsing three-dimensional space from a third-person perspective, and in particular provides a method and system for users to browse three-dimensional space by operating virtual objects through a browser.

With the gradual maturity of stereo image formation and stereo model modeling technology, many ways of using three-dimensional stereo images to present objects have been developed. For example, a camera can be used to capture an image of a scene, and the space can be scanned using stereo modeling software. A three-dimensional image can be formed.

Furthermore, when a three-dimensional space model of a scene is established, the images prepared for this scene can be used for texture mapping. For example, after deconstructing the three-dimensional space model, the area, angle and vertex of each azimuth angle can be obtained, A corresponding image is generated according to each block, and each block image also has three-dimensional spatial coordinate information, and is stored as a file. To generate a 3D space image later, select a 3D space model, perform a pixel-by-pixel mapping of the corresponding block image in a 3D space, and map the texture to generate a 3D space image.

When a three-dimensional image of a space is established by stereo modeling technology, a three-dimensional virtual display space can be realized, and users can use computer input devices (such as mouse, keyboard, Head Mounted Display (HMD), etc. ) to browse this showcase.

Browsing a three-dimensional virtual space pays attention to a sense of immersion in a virtual reality. However, in addition to using a head-mounted display to allow users to experience a better sense of immersion in conventional technologies, it is not easy to have a good experience using a general flat browser. Immersion and practicality are still limited by the 3D image processing capabilities of computer equipment.

In order to provide a better experience of browsing the 3D virtual space, the disclosure paper proposes a method and system for realizing a third-person perspective by using virtual objects, in which different processing programs are used to process the display of 3D space images and provide users with a third-person perspective virtual objects.

The system mainly includes a server, wherein the database stores the 3D space image data of one or more scenes, and provides a 3D space browser executed on the user device, and the 3D space browser downloads the 3D space image data of a scene from the server. The spatial image data can be reconstructed by the first processing program to display the three-dimensional space, and the virtual object can be operated by the second processing program.

According to the embodiment of the method of using virtual objects to realize the third-person perspective, the three-dimensional space browser is executed in the user device, and after being connected to the server, the three-dimensional space image data and the virtual object image are loaded from the server, and reconstructed Finally, a 3D space image displayed on the 3D space browser and a virtual object set at a specific position are formed. Wherein the first processing program is used to process the three-dimensional image, and the second processing program is used to operate the virtual object. When the user operates the virtual object, the second processing program generates an operation instruction according to the user's operation on the virtual object, and the first processing program receives the operation instruction of the second processing program, and can update the three-dimensional space image according to the operation instruction, for example, The server loads 3D space image data corresponding to a certain viewing angle and a station position, and the 3D space image data can be panorama data.

Preferably, the method processes the 3D space and the virtual object displayed in the 3D space browser by executing a browser programming language on the 3D space browser, and sets the style and layout of the display screen with a stacked style sheet.

Further, the virtual object can be a dynamic virtual object, and through the second processing program, the virtual object can respond to the user's operation instruction with animation.

Furthermore, the virtual object can simulate the walking effect in the form of animation switching frames through the cascading style sheet, so as to generate animations of walking forward, moving backward, or turning left and right.

Furthermore, in addition to the virtual objects operated by the user, the server can use different processing procedures to create one or more virtual objects operated by artificial intelligence technology in the three-dimensional space. When the user operates the virtual object, it can pass An interactive function interacts with one or more other virtual objects.

Further, the server can also serve multiple users connected to the server at the same time, and use different processing procedures to process the operations generated by multiple users logging in to the three-dimensional space presented by the three-dimensional space image and operating their respective virtual objects instruction. Similarly, the user can operate the virtual object to interact with one or more other users operating the virtual object in the three-dimensional space through the interactive function.

The disclosure book is about a method and system for realizing a third-person perspective by using virtual objects. One of the technical purposes is to provide users with the ability to browse the three-dimensional space by operating a virtual object (such as a virtual person) when entering a virtual three-dimensional space , using virtual objects to realize the technology of three-dimensional space guidance of the third-person perspective.

However, in order to solve the problem of consuming computing resources while processing 3D images and virtual objects in them, the method proposed in the Disclosure Book to use virtual objects to realize the third-person perspective uses a browser program that supports 3D image processing, allowing 3D spatial data processing and virtual The object processing operates with different processing programs, and provides a communication mechanism between the virtual object and the three-dimensional space processing program, and can achieve the purpose of using virtual objects to realize the third-person perspective in the way of optimizing the calculation program.

Fig. 1 shows a diagram of an embodiment of a system using virtual objects to realize a third-person perspective, in which a server 101 is provided at the server end, and the server 101 provides three-dimensional space image data of one or more scenes, and sends corresponding images according to the request sent by the user. Data, must provide data related to the user's virtual object. In addition, a browser is provided to execute the corresponding service in the user device of the user end. After the browser is connected to the server 101, the scene and the virtual object can be selected, and the browser will start at least two processing procedures. The first processing procedure uses In processing the 3D space image data, including loading the corresponding 3D space image data into the connection server 101 and reconstructing and displaying the 3D space, the second processing program is used to process the display and operation of the virtual object.

According to the illustrated embodiment, a server 101 and a database 110 providing a three-dimensional space browsing service are provided at the system end, and the three-dimensional space image data 111 and user data 113 for one or more scenes are stored in the database 110, The server 101 provides services to the end user devices 103 and 105 through the network 10, allowing the user devices 103 and 105 to access resources in the server 101 through a specific application program. According to the embodiment, the system can provide one or more users to choose to enter the virtual three-dimensional space of a certain scene through the application program, such as virtual showroom, house object, virtual teaching site or game space, etc., and provide interaction between multiple people , or users can interact with other virtual objects in which artificial intelligence technology operates.

According to the embodiment, the third-person perspective system is implemented using virtual objects. The user devices 103 and 105 on the user end install an application program, such as a three-dimensional space browser, such as the three-dimensional space browser 200 shown in FIG. 2 , and provide the user A virtual object 220 that enters into a three-dimensional space 210 and can browse content is set, such as virtual characters, animals, vehicles, or various items.

According to the schematic diagram of an embodiment of using virtual objects to realize the third-person perspective as shown in FIG. 2, the device at the user end can download the 3D space image data of a specific scene from the server, and use the 3D space browser 200 executed in the user device. Processing, after being reconstructed by the first processing program, a visualized three-dimensional space 210 is formed, and then another processing program (second processing program) is used to operate a virtual object 220, including processing the display and operation of the virtual object, allowing the user to The purpose of browsing the three-dimensional space 210 from a third-person perspective is realized on the three-dimensional space browser 200 .

In particular, the virtual object 220 created in the three-dimensional space browser 200 and the three-dimensional space 210 displayed by the three-dimensional space browser 200 are different processing programs, but the browser technology allows the user to operate the virtual object 220 to generate The instruction is transmitted to the processing program of the three-dimensional space 210 . The technical effect achieved in this way is that the virtual object 220 is used to simulate moving in the three-dimensional space 210, allowing the user to operate on the user device, instead of the user moving in the virtual three-dimensional space 210 with a third-person perspective for Simulate the user's movement in the three-dimensional space 210, and because the virtual object 220 does not need to use a three-dimensional model, the calculation of the three-dimensional object is reduced, which can save system performance consumption, so that lower-level devices can experience browsing the three-dimensional space 210 from a third-person perspective immersion.

Further, according to the embodiment, the method of generating the three-dimensional space of the system application proposed in the disclosure can first obtain the panorama of the scene, and then use a space scanner to obtain the depth information of the same space to build a three-dimensional model of the scene. After combining the panorama Form a three-dimensional space image.

One of the technologies is obtained by converting a two-dimensional image into a three-dimensional space image. The deep learning method used in it is based on an artificial neural network. The feature (feature) of the image characteristic, for example, can be described in Figure 3 as the flow embodiment of the deep learning method of the Dual-Projection Network (Dual-Projection Network, DuLa-Net), wherein the depth residue described in Figure 4 is used at the same time. Deep Residual Network (ResNet) deep learning method.

The double-projection network is a deep learning framework (deep learning framework), which is used to predict a three-dimensional space (3D room layout) based on a single full-color panorama (RGB panorama). Among them, in order to obtain better prediction accuracy (prediction accuracy), two prediction results can be obtained first, for example, one is equirectangular panorama-view, and the other is perspective ceiling view (perspective ceiling view), each predicted panoramic view Different cues of the room layout are respectively included, so that a more accurate prediction of the room layout can be obtained. The results can be used in deep learning to train and predict floor plans and patterns. To learn more complex spatial patterns, other three-dimensional data including spatial patterns with different corners can be introduced.

As shown in the figure, in the deep learning method of the dual-projection network, two image processing techniques are used. In the application of the equidistant rectangular panorama view, first input a panorama (301) of a specific area in the space, and pass The feature extraction (303) obtains the equidistant rectangular panoramic view, wherein the step of feature extraction (303) utilizes the deep learning method of the deep residual network to identify and classify the spatial pattern in the image and form the panoramic probability Overview (305). On the other hand, in the application of the see-through ceiling view, first obtain the ceiling view of the area (302), and also use the deep learning method of the deep residual network in the feature extraction (304) to identify and classify The spatial features of the ceiling in the image form a planar probability map (306). Afterwards, the deep learning method of the dual-projection network further combines the panoramic probability map (305) and the planar probability map (306). According to the image information of the two maps, a floor plan fitting process (floor plan fitting) is performed. A two-dimensional plan (2D floor plan) (307) is formed, and the three-dimensional spatial pattern of the region is predicted after three-dimensional space modeling (308). The subsequent process is to continue to generate a three-dimensional pattern diagram for other areas in the space, and then obtain the connection relationship between points, lines, and multiple areas in each area through the process shown in Figure 3, and establish a panoramic view of each site.

Refer to the flow of the deep learning method of the deep residual network shown in FIG. 4 . The deep learning method of the deep residual network is a deep learning method used for image recognition and classification. It is characterized in that it can quickly converge the error of deep learning, and also enables deeper learning and improved accuracy, making it effective and fast. Spatial pattern of recognition and classification.

As shown in the schematic diagram, the panorama 401 of each area in the space is obtained first, and the panorama of the living room, bathroom and bedroom is schematically shown in the figure, and then the calculation of the deep residual network 403 includes image processing 431 and recognition and classification 432 and other deep learning processes, using deep learning to create data sets describing various spatial types from big data. For example, the data sets record data describing areas such as bathroom, bedroom, dining room, kitchen, and living room in an indoor space. , in this example, finally, according to the data of the data set obtained by deep learning, it is judged that each area is the layout of the living room 405a, the bathroom 405b, and the bedroom 405c.

After uploading the 3D space image data based on the above technology to the server, the server can provide a 3D space browsing service by implementing virtual objects from a third-person perspective. The technical concept can refer to the system operation method shown in Figure 5 Embodiment diagram, and the conceptual flow chart of the method for realizing the third-person perspective by using virtual objects shown in FIG. 6 can also be referred to.

The user can load the three-dimensional space image data 511 and the virtual object image 513 from the server 507 through the three-dimensional space browser, and process various objects to be displayed ( three-dimensional space, virtual objects, etc.), including programs such as connecting to the server, sending instructions, and loading images, among which the three-dimensional space image is reconstructed according to the three-dimensional space image data 511, and a static or dynamic virtual object is formed according to the virtual object image 513, The style and layout of the display screen is set by Cascading Style Sheet (CSS) 509 to generate the display screen, and the virtual object can be set at a specific position on the screen. In particular, in the user device executing the three-dimensional space browser 515, the processor establishes processing programs for processing three-dimensional space images and virtual object images respectively, wherein the three-dimensional space images are processed by the first processing program, and the three-dimensional space images are processed by the second processing program Operate virtual objects.

Next, referring to the flow chart of the embodiment shown in FIG. 6, the user operates the virtual object (501) through the user device, for example, through a mouse, a keyboard, or a specific input means (such as a head-mounted display, a mobile device, etc.) The virtual object displayed in the three-dimensional space browser detects the user's operation command through the browser programming language 503, and interprets and generates the operation command 505, and processes the operation command 505 by the second processing program (step S601). According to an embodiment, the second processing program adjusts the viewing angle and position of the virtual object in the three-dimensional space according to the operation instruction 505 generated by the user operating the virtual object. Taking a dynamic virtual object as an example, through the second processing procedure, the virtual object will respond to the user's operation command 505 with animation, such as forward, backward, left or right movement, etc. (step S603 ).

Taking the avatar as an example, change the posture of the avatar and the angle of view in the three-dimensional space in the form of animation switching frames through the cascading style sheet 509 (step S605). Generate an animation of walking forward, walking backward, or turning left and right, and finally arrive at a certain station according to the instruction.

What is mentioned here is that when processing the 3D space images and virtual objects with different processing programs, the two images are displayed on different display layers, and are combined and displayed on the 3D space browser. The virtual object can be a GIF or PNG animation implementation, but is not limited to the implementation of the virtual object animation. Use different posture images to simulate the state of moving in three-dimensional space, such as the appearance of people walking or running in space. However, the animation of the virtual object is not limited thereto, and may include any animation that can save computing resources required for using the three-dimensional model.

After being processed by the second processing program, it means that the user operates the virtual object to reach a station and has a viewing angle facing a direction. At this time, the first processing program can immediately respond to the command generated by the second processing program. When the first processing program for processing three-dimensional space images receives the operation instruction 505 of the second processing program, it updates the three-dimensional space image according to the operation instruction 505, and the updated picture is mainly loaded from the server 507 corresponding to the angle of view and station position 3D spatial image data 511 of .

At the same time, the 3D space image is displayed on the 3D space browser 515 , and after imaging processing (step S607 ), the virtual object is combined through the browser programming language 503 and displayed on the 3D space browser (step S609 ).

In one embodiment, the server 507 can serve multiple users connected to the server 507 at the same time, and process the operation instructions 505 generated by multiple users logging in to the three-dimensional space presented by the three-dimensional image. The server 507 is more capable of handling the interaction of multiple users in the same three-dimensional space, including allowing each user to know or see other users who have logged into the same three-dimensional space from the three-dimensional space image. For related embodiments, refer to the utilization shown in Figure 7 A schematic diagram of an embodiment in which a virtual object realizes a third-person perspective.

For example, the three-dimensional space browser 700 displays a virtual three-dimensional space of an exhibition room, in which there are various exhibits, and the virtual customer service staff implemented by the server through an intelligent robot can be represented by the virtual object 2 722 shown in the illustration, and the virtual object in the three-dimensional space Multiple virtual objects are individually operated by different processing programs, and the technology of intelligent robots can be used to implement each virtual object. Virtual object two 722 can automatically respond to the dialogue information generated by the virtual object one 721 operated by the user, and the user can The function buttons 730 prompted on the screen enable various interactive functions for interacting with other virtual objects, for example, text or voice conversations with the virtual customer service personnel.

Moreover, in yet another embodiment, FIG. 7 shows a three-dimensional space displayed by the three-dimensional space browser 700, and the near end of the screen is a virtual object 721 operated by the user, which can also be accessed through interactive functions, such as text or voice dialogue The function is to interact with other users entering the same three-dimensional space by manipulating their respective virtual objects (such as the virtual object 2 722 ) from a third-person perspective. In this example, the virtual object 2 722 can be another user who logs into the 3D space through the server, which means that the user is active in the 3D space.
