The following describes the technical solutions of the present disclosure and how to solve the above technical problems in specific embodiments. The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present disclosure will be described below with reference to the accompanying drawings.
An embodiment of the present disclosure provides a method for displaying a virtual object, as shown in fig. 1, the method includes:
step S101: the method comprises the steps of obtaining a target object in an image collected by an image collecting device, and obtaining an initial position of the target object in a pre-constructed space environment image, wherein the pre-constructed space environment image is constructed based on current environment data collected by the image collecting device.
The image acquisition device comprises a mobile terminal with a shooting function, such as a mobile phone, a computer, a tablet and other mobile terminals. The pre-constructed spatial environment image may be constructed by current environment data collected by the mobile terminal, and the current environment data may include various data in a viewfinder frame of the mobile terminal.
It is understood that, in an embodiment of the present disclosure, the process of acquiring the target object may include a video shooting process, the acquired image may include a shot image, and when the mobile terminal acquires the image, a spatial environment image may be constructed according to current environment data, where the spatial environment image may be a virtual spatial environment image.
The target object may include an object that the mobile terminal relatively attracts a photographer during photographing, and since the spatial environment image based on the current environment data has been constructed, further, an initial position of the target object in the spatial environment image, that is, an initial spatial position in the virtual spatial environment image may also be acquired.
In one embodiment of the present disclosure, acquiring a target object in an acquired image includes:
step S1011: and carrying out image recognition on the acquired image.
Image recognition refers to a technique of processing, analyzing, and understanding an image with a computer to recognize various different patterns of objects and objects. The acquired images can be subjected to image recognition based on an image recognition neural network model or a saliency target algorithm training model.
The image recognition neural network model can determine the object according to the characteristics of the learned object, so that the acquired image can be subjected to image recognition, and the target object can be recognized and segmented under the condition that the acquired image comprises the target object.
Specifically, a plurality of groups of images can be set as training samples, a plurality of target objects are used as training targets to train an initial neural network model, such as a convolutional neural network model, and then parameters in the convolutional neural network model are adjusted to enable the model to reach a preset convergence condition, so that the training of the image recognition neural network model is completed.
When the collected image is identified by the image identification neural network model, the target object which is learned by the image identification neural network model can be identified, and the identification efficiency is improved.
The saliency target algorithm training model can segment the object with the most visual attraction in the image, so that the collected image can be identified.
By way of example, the most visually appealing objects in an image may include: cats on windowsills, fish in water, or boats on lake surfaces, etc. It will be appreciated that the most attractive of the images may be the object that is distinguished from the environment.
The training process of the saliency target algorithm training model can be a process of highlighting pixel points in the learning image, so that when the target algorithm training model is used for identifying a target object in the image, an object different from the environment (namely the background) in the image can be identified, the target object is further obtained, and the identification range is expanded.
Step S1012: and if the acquired image is identified to include the target object, acquiring the target object.
It can be understood that, in the video shooting process, if a target object is detected in the shooting process, that is, the target object is an object that has been learned by the image recognition neural network model, or the target object is relatively prominent in the captured image, the target object may be segmented, specifically, a physical boundary of the target object may be identified first, and then segmented along the physical boundary of the target object, so as to obtain the target object.
In an embodiment of the present disclosure, the timing of acquiring the target object may be when the acquisition time reaches a preset time, for example, when the time for acquiring a certain image by the image acquisition device is 1 second, it indicates that the user is interested in the object in the image, so that the image can be subjected to image recognition and the target object is acquired.
Step S102: and displaying the target object at a target position in the pre-constructed space environment image in the display interface.
The display interface comprises a video shooting interface, the pre-established spatial environment image can be a virtual spatial environment image, and the target position can comprise a spatial position different from the initial spatial position in the virtual spatial environment image.
It can be understood that, in the video shooting process, after the target object is acquired in the acquired image and the initial spatial position of the target object is acquired in the spatial environment image, the spatial position of the target object in the spatial environment image may be transformed, that is, the target image is displayed at the target spatial position in the pre-constructed spatial environment image in the display interface.
According to the video shooting method and device, the target object in the image collected by the image collecting device is obtained in real time in the video shooting process, so that the obtained target object is more in line with the user requirement, the target object is transformed to the target position from the initial position in the pre-constructed space environment image displayed in the display interface, namely the target object and the space environment image are combined to conduct video creation, and the enthusiasm of user video creation is improved.
In an embodiment of the present disclosure, a method for constructing a pre-constructed spatial environment image is provided, as shown in fig. 2, including:
step S201: and acquiring current environment data through the image acquisition device, wherein the current environment data comprises each object in the acquired image and the distance from each object to the image acquisition device.
It is understood that when the pre-constructed spatial environment image includes a virtual spatial environment image, the current environment data may be acquired by the image acquisition device.
The current environment data not only includes each object in the acquired image and the distance from each object to the image acquisition device, but also includes the pixels of the acquired image.
Taking a video shooting process as an example, in one embodiment of the present disclosure, current environmental data may be collected when a user starts a camera to shoot.
Step S202: and establishing spatial environment information comprising each object based on the acquired each object and the distance from each object to the image acquisition device.
The spatial environment information refers to a digital representation of the environment data uniformly at spatial positions, and the acquired image can be digitized according to the acquired environment data. Specifically, taking a video shooting scene as an example, when a user starts a camera, the image acquisition device may be set as a spatial origin, then a spatial coordinate with the image acquisition device as the spatial origin is established according to the acquired current environment data, for example, the distance between each object and the image acquisition device, and a pixel value of each spatial coordinate point in the spatial coordinate is correspondingly determined according to a pixel value of each pixel point in the acquired image, thereby establishing spatial environment information including each spatial object.
Step S203: and generating a spatial environment image based on the spatial environment information.
It is understood that, after spatial environment information including spatial coordinates of each object with the image capturing device as a spatial origin and a pixel value of each spatial coordinate point is obtained, the spatial environment information may be rendered by using a preset AR engine to generate a virtual spatial environment image.
The virtual space environment image generated by utilizing the distance between each object and the image acquisition device and the pixels can restore the real environment in the virtual environment in equal proportion.
In one embodiment of the present disclosure, establishing spatial environment information including each object based on the acquired each object and a distance from each object to the image acquisition apparatus includes:
step S2021: and respectively collecting the horizontal distance and the vertical distance from each object to the image collecting device.
Step S2022: and establishing three-dimensional space environment information comprising each object based on the acquired each object and the horizontal distance and the vertical distance between each object and the image acquisition device.
It is understood that, when the virtual space environment information is established, in order to improve the viewing experience of the user, the three-dimensional space environment information may be established. The three-dimensional space environment information including each object can be established by acquiring the horizontal distance and the vertical distance from each object to the image acquisition device.
Specifically, taking a video shooting scene as an example, when a user starts a camera, the image acquisition device may be set as a spatial origin, a three-dimensional spatial coordinate system with the image acquisition device as the spatial origin is established, then, according to the acquired current environment data, for example, the horizontal distance and the vertical distance between each object and the image acquisition device, each horizontal distance and each vertical distance are respectively projected to each coordinate axis, a spatial coordinate of each object in the three-dimensional spatial coordinate system is obtained, and a pixel value of each pixel point in the acquired image is used to determine a pixel value of each spatial coordinate point in the three-dimensional spatial coordinate system, thereby establishing three-dimensional spatial environment information including each object.
It should be noted that, in order to make the three-dimensional space image more vivid, a plurality of acquisition points may be set in each object, each object includes a plurality of acquisition points, and by acquiring vertical distances and horizontal distances from the plurality of acquisition points of the object to the image acquisition device, the three-dimensional space image generated by the established three-dimensional space environment information may be more stereoscopic, and the viewing experience of the user may be improved.
In one embodiment of the present disclosure, establishing spatial environment information including each object based on the acquired each object and a distance from each object to the image acquisition apparatus includes:
step S2023: and respectively collecting Euclidean distances from each object to the image collecting device.
Step S2024: and establishing two-dimensional space environment information comprising each object based on the acquired each object and the Euclidean distance from each object to the image acquisition device.
It can be understood that, when the virtual space environment information is established, some image acquisition devices do not support displaying a three-dimensional stereo image, so that two-dimensional space environment information can be established. The two-dimensional space environment information including each object can be established by acquiring the Euclidean distance from each object to the image acquisition device.
Specifically, taking a video shooting scene as an example, when a user starts a camera, the image acquisition device may be set as a spatial origin, a two-dimensional spatial coordinate system with the image acquisition device as the spatial origin is established, then, according to the acquired current environmental data, for example, the euclidean distances from each object to the image acquisition device, the euclidean distances are projected to each coordinate axis, spatial coordinates of each object in the two-dimensional spatial coordinate system are obtained, and the pixel value of each spatial coordinate point in the two-dimensional spatial coordinate system is determined by using the pixel value of each pixel point in the acquired image, so as to establish two-dimensional spatial environmental information including each object.
It should be noted that, in order to make the two-dimensional spatial image more vivid, a plurality of acquisition points may be set in each object, each object includes a plurality of acquisition points, and by acquiring euclidean distances from the plurality of acquisition points of the object to the image acquisition device, the two-dimensional spatial image generated by the established two-dimensional spatial environment information may be closer to the real environment, thereby improving the viewing experience of the user.
In one embodiment of the present disclosure, presenting a target object at a target position in a pre-constructed spatial environment image in a presentation interface includes:
step S1021: and carrying out deformation processing on the target object, wherein the deformation processing comprises at least one of movement, rotation and scaling.
It is understood that, in order to improve the creation interest of the video creator, the target object may be subjected to a deformation process, and specifically, the target object may be subjected to a deformation operation such as moving, rotating, or zooming.
It should be noted that, since the virtual space environment may be constructed in advance, the movement of the target object at this time includes the movement within the virtual space environment, that is, the virtual space coordinates of the target object are changed, and the movement of the target object may also be understood as a process of re-determining the spatial display position of the target object.
It can be understood that the movement of the target object may be movement following the movement of the image capturing device, and taking a video shooting scene as an example, after the image capturing device captures an image and identifies the target object, the image capturing device may display a pre-constructed virtual spatial environment image, and when the image capturing device moves to view spatial environment images at other angles, the target object may move following the image capturing device until a suitable spatial position is selected.
The operation of rotating or zooming the target object may also be considered as a change in the coordinates of the target object in the virtual space.
Step S1022: and displaying the target object after the deformation processing at a target position in a pre-constructed space environment image in a display interface.
The step of displaying the target object after the deformation processing at the target position in the virtual space environment may be understood as determining the virtual space coordinate of the target object at the target position in the virtual space environment after the target object is transformed by the virtual space coordinate of the initial position.
It should be noted that, after receiving a presentation instruction for the target object, the target object may be presented at a target position in the pre-constructed spatial environment image. The display instruction comprises a preset time display instruction, a preset voice display instruction or a preset operation display instruction.
The preset time display instruction, for example, the time for obtaining the target object 1 reaches 1 second, and the preset voice display instruction, for example, receiving the voice display instruction and the preset operation display instruction, for example, receiving the display trigger operation, may be both used as the display instruction for the target object.
By setting the display time, the process of displaying the target object at the target position in the pre-constructed space environment image is more diversified.
In one embodiment of the present disclosure, presenting a target object at a target position in a pre-constructed spatial environment image in a presentation interface includes:
step S1023: and acquiring first space environment information of the target object after deformation processing.
The first spatial environment information of the target object may include virtual spatial coordinates of the target object in the virtual spatial environment, and it is understood that, after the target object is subjected to at least one of deformation operation processing of moving, rotating and scaling in the virtual spatial environment, the virtual spatial coordinates of the target object in the virtual spatial environment are changed accordingly, and at this time, the virtual spatial coordinates of the target object in the virtual spatial environment after the deformation processing and the pixel value of each virtual spatial coordinate point may be acquired again.
Step S1024: and superposing the spatial environment information of each object and the first spatial environment information of the target object to obtain second spatial environment information.
It can be understood that, after the target object is subjected to various deformation processes in the virtual space environment, and other objects in the virtual space environment are not changed, in order to provide a smooth shooting experience for a user, the spatial environment information of other objects in the virtual space environment and the first environment information of the target object may be superimposed to obtain the second spatial environment information.
The second space information comprises virtual space coordinates of each object in the virtual space image, virtual space coordinates of the target object after deformation processing, and a pixel value of each virtual space coordinate point.
Step S1025: and rendering the second spatial environment information to enable the target object to be displayed at the target position in the pre-constructed spatial environment image in the display interface.
It can be understood that, in order to redisplay the target object after the deformation processing in the display interface, the preset AR engine may be used to render the second spatial environment information, and after the rendering is successful, the deformed target object may be displayed at the target position in the spatial environment image pre-constructed in the display interface.
