It should be understood that the number of terminal devices, networks, and servers in fig. 1 is merely illustrative. There may be any number of terminal devices, networks, and servers, as desired for implementation.
With continued reference to FIG. 2, a flow 200 of one embodiment of a method for displaying information in accordance with the present application is shown. The method for displaying information comprises the following steps:
In this embodiment, an electronic device (e.g., the smart terminal shown in fig. 1) on which the method for displaying information operates may monitor the focal length data of the lens in real time.
In order to set a virtual three-dimensional object in a virtual space, the present embodiment needs to monitor focal length data of a lens of the intelligent terminal. Generally, a lens of a smart terminal has a capability of automatically adjusting a focal length. The lens can automatically adjust the focal length according to different positions of an imaged object. When a certain point in an image collected by the lens is clicked on a display screen of the intelligent terminal, the lens can normally automatically adjust the focal length and obtain a clear image by taking the point as a focus. When the lens can acquire a clear image of an imaged object, the focal length data of the lens at the moment can represent the distance between the imaged object and the lens. Therefore, the distance between the imaged object and the lens (i.e., the depth of field) can be obtained by monitoring the focal length data of the lens.
And step 202, determining the placement position of the virtual three-dimensional object in the virtual space through the focal distance data.
After the focal length data is acquired, the distance between the imaged object and the lens can be determined. On the basis of the position, the placement position of the virtual three-dimensional object in the virtual space is determined. The virtual space is stored on the intelligent terminal and comprises a virtual three-dimensional object with a preset size.
In some optional implementations of the present embodiment, the determining a placement position of the virtual three-dimensional object in the virtual space by the focal distance data may include the following steps:
the first step is to determine the focal position of the focal point corresponding to the focal length data in the virtual space.
The focal length data is acquired, which indicates that the lens at this time can already measure the distance between the focal point and the lens in the physical space corresponding to the focal length data. In the augmented reality technology, the virtual space and the physical space have a corresponding relationship, so that the focus position of the focus in the virtual space can be determined through the corresponding focus of the focal length data in the physical space.
And secondly, acquiring a plurality of spatial focal length data within the set range of the focal position, and constructing a virtual object placing space according to the spatial focal length data.
The focal position of the focal point in the virtual space corresponds to only one point in the virtual space. In order to place a virtual three-dimensional object having a preset size, it is necessary to construct a virtual space around the focal position and then place the virtual three-dimensional object in the virtual space. In the present embodiment, a plurality of spatial focal length data are acquired within the above-described setting range of the focal position. Here, the spatial focal length data is also acquired by acquiring a plurality of other focal points within a set range of focal positions through the lens. For example, a plurality of other focuses may be selected from an image captured by a lens displayed on the smart terminal, or the lens may be set so that the lens can automatically obtain the plurality of other focuses around the focus position. Since the physical space and the virtual space have a corresponding relationship, the focal length data between the lens and the plurality of other focal points corresponds to the spatial focal length data of the lens and the plurality of other focal points in the virtual space. Generally, a plurality of other focal points belong to the same or different planes in the physical space, and therefore, at least one plane in which the focal points corresponding to the plurality of spatial focal length data are located in the virtual space can be determined by a plane fitting method or the like. And then constructing a virtual object placing space through the surface. The virtual object placing space is used for placing a virtual three-dimensional object.
And thirdly, setting a placing position of the virtual three-dimensional object in the virtual object placing space based on the preset size of the virtual three-dimensional object.
After the virtual object placement space is constructed, a space position can be selected in the virtual object placement space to place a virtual three-dimensional object.
In some optional implementations of this embodiment, the constructing the virtual object placement space by using the spatial focal length data may include: and calculating distance information and angle information between the space focus position corresponding to each space focal length data and the lens to obtain a space position relation between the space focus positions, and constructing a virtual object placing space based on the space position relation.
When constructing the virtual object placement space, it is necessary to first determine faces in a plurality of virtual spaces. The plurality of spatial focal length data are acquired within the set range of the focal position, and under the condition that the position of the lens in the physical space is not changed, distance information and angle information between the spatial focal position corresponding to each spatial focal length data and the lens can be calculated, so that the spatial position relation among the plurality of spatial focal positions is obtained; then, on the basis of the spatial position relationship, at least one virtual space surface corresponding to the spatial focus position can be determined by methods such as plane fitting and the like; finally, a virtual object placement space is constructed from the at least one face.
And 203, displaying the virtual three-dimensional object on a display screen of the intelligent terminal after the virtual three-dimensional object is arranged at the placing position.
After the virtual three-dimensional object is arranged at the placement position, the virtual three-dimensional object in the virtual space can be displayed through a display screen of the intelligent terminal.
In some optional implementation manners of this embodiment, after the virtual three-dimensional object is set at the placement position, displaying the virtual three-dimensional object on the display screen of the intelligent terminal may include the following steps:
firstly, monitoring the display range of the display screen for displaying the virtual space.
The virtual three-dimensional object is placed in a virtual space formed in the intelligent terminal. Theoretically, how large a physical space is and how large a virtual space is. And the display space of the display screen of the intelligent terminal is in a range. In order to reasonably display the virtual three-dimensional object, the display range of the display screen for displaying the virtual space needs to be determined. Since the physical space and the virtual space have a corresponding relationship, a display range in which the virtual space is displayed corresponds to a display range in which the physical space is displayed. And the display range quantization mode of the physical space can also be obtained through the focal length information of the lens. Therefore, the display range of the virtual space can be obtained correspondingly. The display range is a physical space range displayed by a display screen of the intelligent terminal, and the display range can also be a virtual space range displayed by the display screen of the intelligent terminal due to the fact that the physical space and the virtual space have a corresponding relation. The display range may be indicated by a certain length unit (for example, the length unit may be meter), and the indication may be displayed on a display screen of the intelligent terminal or may not be displayed. The display range of the corresponding display screen may be: the display range in the horizontal direction is 5 meters, and the display range in the vertical direction is 3 meters.
And secondly, determining the display size of the virtual three-dimensional object in the display screen according to the display range and the preset size of the virtual three-dimensional object.
The virtual three-dimensional object has a preset size, and the size of the virtual three-dimensional object on the display screen of the intelligent terminal can be determined by comparing the display range after the display range of the virtual space is obtained. When the virtual three-dimensional object is drawn close to the display screen, the display range of the virtual space on the display screen is reduced, and correspondingly, the size of the virtual three-dimensional object on the display screen is increased; for example, the display range of the display screen may be: the display range in the horizontal direction is 5 meters, the display range in the vertical direction is 3 meters, and the preset size of the virtual three-dimensional object is 1 meter by 1 meter. The virtual three-dimensional object occupies a display section of 1/5 in the horizontal direction and 1/3 in the vertical direction within the current display range. Conversely, when the virtual three-dimensional object is zoomed out on the display screen, the display range of the virtual space on the display screen is enlarged, and correspondingly, the size of the virtual three-dimensional object on the display screen is reduced. For example, after zooming out, the display range of the display screen may be: the display range in the horizontal direction is 10 meters, the display range in the vertical direction is 6 meters, and the preset size of the virtual three-dimensional object is still 1 meter by 1 meter. The virtual three-dimensional object occupies a display section of 1/10 in the horizontal direction and 1/6 in the vertical direction within the current display range. Compared with the zooming-in situation, under the zooming-out situation, the size of the virtual three-dimensional object on the display screen of the intelligent terminal is obviously smaller than that of the virtual three-dimensional object on the display screen of the intelligent terminal under the zooming-in situation. Therefore, the automatic size adjustment of the virtual three-dimensional object on the display screen of the intelligent terminal is realized, and the authenticity and the display precision of the virtual three-dimensional object on the display screen of the intelligent terminal are improved.
With continued reference to fig. 3, fig. 3 is a schematic diagram of an application scenario of the method for displaying information according to the present embodiment. In the application scenario of fig. 3, two virtual three- dimensional objects 403 and 404 with identical preset sizes are placed on the desktop 401 and the ground 402 in the virtual space of the terminal device 102, respectively, based on the focal length data of the lens of the terminal device 102; when the terminal device 102 is in the position shown in fig. 3, the display size of the virtual three- dimensional objects 403 and 404 in the display screen of the smart terminal may change with the difference of the focal length data (i.e., the distance between the virtual three-dimensional object and the lens) (the display size of the virtual three-dimensional object far from the lens on the display screen is smaller than the display size of the virtual three-dimensional object near the lens on the display screen), so that the reality and accuracy of the display of the virtual three- dimensional objects 403 and 404 on the display screen of the smart terminal are improved.
According to the method provided by the embodiment of the application, the placing position of the virtual object in the virtual space is determined through the focal length data, so that the accuracy of the placing position of the virtual object in the virtual space is improved; after the virtual object is arranged at the placing position, the virtual object is displayed on a display screen of the intelligent terminal, and the display precision of the virtual object on the intelligent terminal is improved.
