[0029] Figure 1 A flowchart of a virtual object generation method according to an embodiment of the present disclosure is provided. The embodiment can be applied to the generation of a virtual object in a three-dimensional space. The method can be performed by a virtual object generation device, which can be composed of hardware and / or software, and can be integrated in a device having a virtual object generation function, such as a server, a mobile terminal, or a server cluster. As shown in Figure 1 The method specifically includes the following steps:

[0030] S110, obtaining position information and attitude information of a virtual object frame in a three-dimensional space.

[0031] The virtual object frame is hung on an object identified in the three-dimensional space and is used to place a virtual object. The virtual object frame can include multiple virtual object frames. In the embodiment, the virtual object can be a virtual object corresponding to any theme, such as a "Dragon Boat Festival" theme. The virtual object can be a virtual dragon boat, a virtual zongzi, etc., which is not limited here.

[0032] The position information can be coordinate information of a center point of the virtual object frame in a three-dimensional space, and the attitude information can include a yaw angle, a pitch angle and a roll angle of the virtual object frame in the three-dimensional space.

[0033] In this embodiment, the coordinate information of the center point of the virtual object frame in the three-dimensional space can be determined according to SLAM (Simultaneous localization and mapping) information, and the attitude information of the virtual object frame in the three-dimensional space can be determined by a normal estimation algorithm. This embodiment is not limited.

[0034] In this embodiment, the virtual object frame can be determined in the following manner: performing object detection on a current frame; and determining the virtual object frame according to the detected object. Specifically, the size of the virtual object frame can be determined according to the detection frame of the object. For example, the size of the virtual object frame can be smaller than or equal to the detection frame of the object, or the detection frame of the object can be split to obtain multiple virtual object frames.

[0035] In S120, the size information of the virtual object frame in the three-dimensional space is determined according to the attitude information.

[0036] The size information can be an aspect ratio, and therefore, the height and the width of the virtual object frame in the three-dimensional space need to be obtained, and the height and the width are compared to obtain the aspect ratio.

[0037] Optionally, the manner of determining the size information of the virtual object frame in the three-dimensional space according to the attitude information can be: determining a second height of the virtual object frame in the three-dimensional space according to a first height of the virtual object frame in a pixel plane and a pitch angle; determining a second width of the virtual object frame in the three-dimensional space according to a first width information of the virtual object frame in the pixel plane and a yaw angle; and comparing the second height and the second width to obtain an aspect ratio of the virtual object frame in the three-dimensional space.

[0038] Specifically, the first height is multiplied by the cosine of the pitch angle to obtain the second height of the virtual object frame in the three-dimensional space, and the first width is multiplied by the cosine of the yaw angle to obtain the second width of the virtual object frame in the three-dimensional space. The aspect ratio of the virtual object frame in the three-dimensional space is determined based on the attitude information, which can accurately determine the size information of the virtual object frame, facilitating the selection of the target material.

[0039] In S130, the target material is determined according to the size information.

[0040] The target material can be understood as a material placed in the virtual object frame, which can be a material of any theme and designed and stored in a material library by a developer. In this embodiment, the size of the target material matches the size information of the virtual object frame in the three-dimensional space.

[0041] Optionally, the way of determining the target material according to the size information can be: determining a material that does not appear in the historical period as the candidate material; and determining the target material from the candidate material according to the size information.

[0042] The historical period can be understood as the last N seconds, and N can be any positive integer. Specifically, first, the materials in the material library that are rendered to the three-dimensional space in the last N seconds are filtered out, then the remaining materials are determined as candidate materials, and finally the target material is determined from the candidate materials according to the aspect ratio of the virtual object frame in the three-dimensional space. The advantage of this is that it can prevent the same material from appearing repeatedly in a short period of time and improve the diversity of virtual object generation.

[0043] Optionally, the process of determining the target material from the candidate material according to the size information can be: classifying the candidate materials according to the aspect ratio to obtain a plurality of material classes; determining the material class corresponding to the virtual object frame as the target material class according to the size information; and determining the target material from the target material class.

[0044] The aspect ratio categories can include an aspect ratio greater than 1, an aspect ratio equal to 1, and an aspect ratio less than 1. Therefore, the plurality of material classes includes a material class with an aspect ratio greater than 1, a material class with an aspect ratio equal to 1, and a material class with an aspect ratio less than 1. Specifically, if the aspect ratio of the virtual object frame in the three-dimensional space is greater than 1, the material class with an aspect ratio greater than 1 is determined as the target material class; if the aspect ratio of the virtual object frame in the three-dimensional space is equal to 1, the material class with an aspect ratio equal to 1 is determined as the target material class; and if the aspect ratio of the virtual object frame in the three-dimensional space is less than 1, the material class with an aspect ratio less than 1 is determined as the target material class. Finally, a target material is determined from the target material class.

[0045] Optionally, the way of determining the target material from the target material class can be: randomly selecting a material from the target material class to determine as the target material; or determining the material in the target material class with the smallest difference between the aspect ratio and the aspect ratio of the virtual object frame as the target material.

[0046] Specifically, if the target material class is a material class with an aspect ratio greater than 1, a material is randomly selected from the material class with an aspect ratio greater than 1 as the target material. If the target material class is a material class with an aspect ratio equal to 1, a material is randomly selected from the material class with an aspect ratio equal to 1 as the target material. If the target material class is a material class with an aspect ratio less than 1, a material is randomly selected from the material class with an aspect ratio less than 1 as the target material. In this embodiment, the target material is determined based on the classified candidate materials, which can improve the efficiency of determining the target material.

[0047] Specifically, if the target material class is a material class with a length-width ratio greater than 1, the specific length-width ratio of each material in the material class with a length-width ratio greater than 1 is calculated, and the difference between each specific length-width ratio and the length-width ratio of the virtual object frame is calculated. The material with the smallest difference value is taken as the target material. If the target material class is a material class with a length-width ratio less than 1, the specific length-width ratio of each material in the material class with a length-width ratio less than 1 is calculated, and the difference between each specific length-width ratio and the length-width ratio of the virtual object frame is calculated. The material with the smallest difference value is taken as the target material. In this embodiment, the material with the smallest difference value is determined as the target material, which can improve the matching degree of the target material and the virtual object frame.

[0048] In S140, the target material is rendered into the virtual object frame according to the position information and the attitude information, and a virtual object is generated.

[0049] The position information is the coordinate information of the center point of the virtual object frame in the three-dimensional space. Specifically, the center point of the target material is aligned with the center point of the virtual object frame in the three-dimensional space, and the target material is rendered after adjusting the attitude of the target material according to the attitude information, so as to obtain the virtual object.

[0050] Specifically, the target material is rendered into the virtual object frame according to the position information and the attitude information, and a virtual object is generated. The way can be: obtaining the depth information of the virtual object frame in the three-dimensional space; scaling the target material according to the depth information; and rendering the scaled target material into the virtual object frame according to the position information and the attitude information.

[0051] The depth information can be the distance between the center point of the virtual object frame and the optical center of the camera. The scaling of the target material can be a proportional scaling, so that the scaled target material can be completely surrounded by the virtual object frame, preventing the rendered virtual object from overflowing the virtual object frame, thereby avoiding overlapping with other virtual objects. Based on the depth information, the target material is scaled, which can improve the three-dimensional sense of the virtual object.

[0052] Optionally, the way of scaling the target material according to the depth information can be: determining a scaling ratio according to the depth information; and scaling the target material according to the scaling ratio.

[0053] The depth information and the scaling ratio have a certain corresponding relationship, and the depth information and the scaling ratio are inversely proportional. The greater the depth information, the greater the scaling ratio, that is, it conforms to the perspective principle. The farther the object is, the smaller the size of the object in the picture.

[0054] Specifically, after scaling the target material according to the scaling ratio, the center point of the scaled target material is aligned with the center point of the virtual object frame in the three-dimensional space, the pose of the scaled target material is adjusted according to the pose information, and finally rendering is performed to obtain the virtual object. The advantage of this is to ensure that the rendered virtual object fits the virtual object frame and improve the display effect of the virtual object.

[0055] The technical scheme of the embodiment of the present disclosure obtains position information and pose information of a virtual object frame in a three-dimensional space, determines size information of the virtual object frame in the three-dimensional space according to the pose information, determines a target material according to the size information, and renders the target material into the virtual object frame according to the position information and the pose information to generate a virtual object. The method for generating a virtual object provided by the embodiment of the present disclosure can determine a target material according to the size information of a virtual object frame, which can improve the size matching degree of the scaled material and the virtual object frame, thereby improving the display effect of the virtual object and further improving the display quality of the image.
