Detailed Description

For the purposes of promoting an understanding of the principles and advantages of the disclosure, reference will now be made to the embodiments illustrated in the drawings and specific language will be used to describe the same.

It should be noted that unless otherwise defined, technical or scientific terms used in the embodiments of the present disclosure should be given the ordinary meaning as understood by one of ordinary skill in the art to which the present disclosure pertains. The terms "first," "second," and the like, as used in embodiments of the present disclosure, do not denote any order, quantity, or importance, but rather are used to distinguish one element from another. The word "comprising" or "comprises", and the like, means that the steps preceding the word are meant to encompass the steps listed after the word as well as equivalents thereof, without excluding other steps. "upper", "lower", "left", "right", etc. are used merely to indicate relative positional relationships, which may also be changed when the absolute position of the object to be described is changed.

As described in the background section, the simulation effect of the virtual object generated by XR is still unsatisfactory, for example, the proportion of the virtual object and the real object in the augmented reality device is unbalanced, and the user is sometimes required to adjust and place the virtual object and the real object in the augmented reality device in a correct position.

In view of this, the embodiments of the present disclosure provide a simulation method for a virtual object, so that the virtual object can adapt to an object in a first scene, thereby optimizing XR man-machine interaction, and enabling a user to obtain better XR experience.

Fig. 1 shows a flow chart of a simulation method of a virtual object according to an embodiment of the disclosure. Specifically, the simulation method includes:

step S101: acquiring scene information of a first scene; wherein the first scene includes at least one object.

Here, the first scenario is a real environment scenario where the user uses the XR device, such as a bedroom, living room, beach, etc.

As will be appreciated by those skilled in the art, a first scene may include a plurality of objects, and different first scenes, the corresponding objects being different. Illustratively, please refer to fig. 2, which shows that the first scene image contained in the scene 200 is a bedroom, and the objects include, but are not limited to, beds, curtains, skylights, cupboards, and bed sheets.

In some embodiments, the scene information is point cloud data.

Note that Point Cloud data (Point Cloud) refers to a massive set of points of the target surface characteristics. Typically obtained by laser or photogrammetry.

In the embodiment of the disclosure, the point cloud data may be a laser point cloud, a photographic point cloud, or a combination of the two, which is not limited in particular. The laser point cloud typically includes three-dimensional coordinates (XYZ) and laser reflection intensity; the photographing point cloud generally includes three-dimensional coordinates (XYZ) and color information.

Here, the point cloud data may be acquired by a sensor. Optionally, the sensor is selected from one or more of a lidar, a 3D image sensor, a depth sensor, a Time-of-Flight (ToF) sensor. The above list is merely exemplary and not limiting of the sensors, and those skilled in the art may select other suitable sensors, and are not limited herein.

Alternatively, the sensor may be disposed on an XR device, such as a head mounted display device, or may be disposed in the first scene, without limitation.

In some alternative embodiments, the point cloud data of the first scene is acquired by an intelligent terminal, such as a mobile phone configured with a TOF sensor, and then transmitted to the XR device via a network, thereby acquiring the point cloud data of the first scene.

That is, the point cloud data may be acquired by the XR device itself, or may be acquired by other terminals, which is not limited in this disclosure.

In some alternative embodiments, the scene information is image data. The image data may be acquired by an image acquisition device (e.g., a camera). Similar to the sensors described above, the image acquisition device may be disposed on the XR device, or disposed in the first scene, to acquire image data. Of course, the image data may also be acquired by a smart terminal (e.g., a cell phone, ipad, etc.) and transmitted to the XR device.

In some embodiments, the scene information includes point cloud data and image data. The method for acquiring the point cloud data and the image data is as described above and will not be described in detail.

Step S103: and determining characteristic information of each object according to the scene information.

Here, the characteristic information may indicate physical characteristics of the objects, such as size, hardness, texture, color, and the like, and may indicate a relative positional relationship between the objects, and the like, which are not illustrated here.

It should be noted that the feature information may be represented in the form of a semantic tag, or may be any other manner capable of indicating the object characteristics, which is not limited in this disclosure.

In some optional embodiments, the step of determining feature information of each of the objects according to the scene information includes:

determining the number of the objects and the characteristic information of each object according to the scene information by using a characteristic extraction model; wherein the feature extraction model is a machine learning model.

The feature extraction model is a machine learning model trained in advance. Illustratively, the machine learning model may be based on a deep neural network, a convolutional neural network, or the like. By way of example, the training of the feature extraction model may employ supervised learning, semi-supervised learning, or unsupervised learning, as not limited thereto.

Those skilled in the art will appreciate that the feature extraction model may employ one algorithm, or may be a combination of algorithms, which is not limited in this disclosure.

For example, if the scene information is point cloud data, the training data of the machine learning model is the point cloud data, and the adopted algorithm may include a minimum Zhang Shu algorithm, a connection graph algorithm and the like.

For example, if the scene information is image data, the training data of the machine learning model is image data, and the adopted algorithm may include an image recognition algorithm, a three-dimensional reconstruction algorithm, and the like. As will be appreciated by those skilled in the art, based on image data from different angles, the three-dimensional size of an object in an image may be calculated, for example using a multi-objective SLAM algorithm in an instant localization and mapping algorithm (Simultaneous Localization and Mapping, abbreviated SLAM).

Of course, if the scene information includes point cloud data and image data, a person skilled in the art may combine various algorithms and train to obtain the feature extraction model based on the point cloud data and the image data. The present disclosure is not particularly limited thereto.

Step S105: responding to a user to determine a virtual object and a target position of the virtual object in a second scene, and determining a matched simulation effect according to characteristic information of an object corresponding to the target position and the virtual object;

For example, the augmented reality device may present the second scene via a head mounted display device, VR glasses, projector, or the like. In some embodiments, the augmented reality device comprises a near-eye display device, the display scene of the near-eye display device being the second scene.

The second scene is a scene in which a real scene (corresponding to the first scene) and a virtual scene are fused.

Here, the user may select the virtual object (e.g., pillar 201, apple 202 in fig. 2) and the target position of the virtual object in the second scene by hand, handle, etc. As will be appreciated by those skilled in the art, when a user determines a target location, the distance of the virtual object from the user, the distance of the object from the target location, and the like may be generally considered to be less than or equal to zero.

And determining a matched simulation effect by utilizing the characteristic information of the object corresponding to the target position and the virtual object, so that the virtual object and the object in the second scene can present a more real effect, and the immersion of the user is increased.

In some embodiments, the characteristic information includes size information; the step of determining the matched simulation effect according to the characteristic information of the object corresponding to the target position and the virtual object comprises the following steps:

determining the proportional relation between the virtual object and the object according to the preset size information of the virtual object and the size information of the object corresponding to the target position; here, the preset size information may be determined based on the size of the real object of the virtual object, for example, the size of the virtual apple (virtual apple 202 in fig. 2) is determined based on the size of the real apple, and the size of the virtual dart (virtual dart 403 in fig. 4) is determined according to the size of the real dart.

Based on the scaling relationship, a display size of the virtual object that matches a display size of the object in the second scene is determined. Taking the characteristics of the near size and the far size of the object in the display image into consideration, the adoption of the display size can ensure the proportion coordination of the virtual object and the object in the second scene.

The display size of the object may be obtained by an augmented reality device (e.g., a near-eye display device) or may be obtained by scene information, which is not limited herein.

In this way, the dimensional proportion of the virtual object and the object can be ensured to be coordinated, and the real state is more similar.

In some optional embodiments, after the step of determining the display size of the virtual object that matches the display size of the object in the second scene, further comprising:

determining a relative positional relationship of the virtual object and the object in the second scene based on the target position, the display size of the virtual object, and the display size of the object; here, the relative positional relationship is a complete overlap, for example, the virtual object is completely placed on the object (the virtual apple 202 is located on the sheet as shown in fig. 2), and the virtual object is completely covered by the cover, for example, the virtual tablecloth is covered on the table; the relative positional relationship may also be partially overlapping, for example, the virtual cup may be partially on a table and partially suspended.

Determining a superimposed area of the virtual object and the object in the second scene in response to the relative positional relationship being a partial overlap; alternatively, the overlapping area may be calculated from the target position, the size of the virtual object in the second scene, and the size of the object.

And determining that the simulation effect comprises a moving picture of the virtual object separated from the object in response to the superposition area being smaller than half of the projection area of the virtual object to the direction of the object.

By the method, the real feeling of placing the virtual object by the user can be increased, and the interaction diversity is increased.

In some embodiments, the characteristic information further comprises location information; here, the positional information includes a relative position between objects, such as a bed sheet on a bed, a table in the middle of a floor, a cabinet on the floor and against a wall, which is not limited herein.

As shown in fig. 7, after the step of determining that the simulation effect includes the virtual object moving away from the moving picture of the object, the method further includes:

step S701: and determining the moving direction of the virtual object away from the object based on a preset gravity direction.

It should be noted that the preset gravity direction may be identical to the real gravity direction, or may be different from the real gravity direction, so that the interactive interest may be increased by the preset gravity direction.

Step S703: determining an object corresponding to the virtual object at a moving end point according to the moving direction and the position information;

step S705: and determining a matched simulation effect according to the characteristic information of the object corresponding to the moving end point and the virtual object.

The simulation effect includes at least one of a display effect and a sound effect. When the object corresponding to the target position and the object corresponding to the moving end point are different, the corresponding simulation effects are different.

In some embodiments, the characteristic information includes texture information; the step of determining the matched simulation effect according to the characteristic information of the object corresponding to the target position and the virtual object comprises the following steps:

and matching the preset material information of the virtual object with the material information of the object corresponding to the target position by utilizing a preset display effect library to obtain an attached display effect of the virtual object on the object.

It should be noted that, the preset material of the virtual object will also affect the adhesion display effect of the virtual object after being placed on the object.

The preset display effect library comprises different virtual objects and various corresponding material information thereof, different objects and corresponding material information thereof, and the attachment display effects corresponding to various combinations. In response to determining the virtual object and its material information, the attachment display effect can be obtained by matching.

Based on the attached display effect, a corresponding display effect can be realized by using the existing image processing tool. The image processing tool can be flexibly selected by those skilled in the art, and is not particularly limited herein.

Here, the adhesion display effect includes object wrinkles, object ripples, object cracks, dipping, and the like.

Illustratively, referring to fig. 2, the virtual object is a virtual apple 202, and if the material is consistent with a real apple, the sheet will exhibit the creasing effect as shown in fig. 3 due to the weight of the virtual apple 202 when the virtual apple is placed on the sheet. If the material is plastic, the virtual apple 202 is lighter in weight, and the sheet has little or no wrinkles.

Illustratively, referring to fig. 2, the virtual object is a virtual pillar 201, and in combination with the virtual pillar 201 having a size larger than that of the room, the virtual pillar 201 is made of a hard incompressible material, and then a crack effect is exhibited at a corresponding position in the room.

Illustratively, referring to the display scene 400 of fig. 4, the virtual object is a dart 403, and if the material of the virtual object is steel, the wall may exhibit a crack effect as shown in fig. 6.

Illustratively, referring to the display scenario 400 of fig. 4, the virtual object is a duck 402, and if water is within the pond 401, the water exhibits a ripple effect as shown in fig. 5.

Further, responding to the number of objects corresponding to the target position to be a plurality of objects; the step of obtaining the attachment display effect of the virtual object placed on the object by matching according to the preset material information of the virtual object and the material information of the object corresponding to the target position by using a preset display effect library comprises the following steps:

and matching the preset material information of the virtual object with the material information of each object corresponding to the target position by using a preset display effect library to obtain corresponding attached display effects.

Illustratively, referring to display scenario 400 of FIG. 4, the virtual object is a pond 401; the target position corresponds to the ground 405 and the carpet 404, and if the ground 405 is made of marble, the pond 401 will cause the display effect of marble cracks, water is in the pond 401, and the carpet 404 is made of cashmere, the display effect of adhesion in the soaking water is formed.

In some embodiments, the simulation method further comprises:

and matching by utilizing a preset sound effect library according to the preset material information of the virtual object and the material information of the object corresponding to the target position to obtain the attached sound effect of the virtual object placed on the object.

Here, the preset sound effect library is similar to the preset display effect library, except that the sound effect and the display effect are matched, respectively.

Illustratively, the plastic cup falls on a marble floor, the corresponding sound effect being bouncing sound; the ceramic cup falls on the marble floor, and the corresponding sound effect is breakage sound.

It will be appreciated by those skilled in the art that the playing of the attached sound effects may be accomplished by playing pre-recorded sound.

It should be noted that the method of the embodiments of the present disclosure may be performed by a single device, such as a computer or a server. The method of the embodiment can also be applied to a distributed scene, and is completed by mutually matching a plurality of devices. In the case of such a distributed scenario, one of the devices may perform only one or more steps of the methods of embodiments of the present disclosure, the devices interacting with each other to accomplish the methods.
