It should be noted that all matters in the drawings in the embodiments of the present invention can satisfy the requirements of sufficient disclosure.
S102: responding to the action of adjusting the parameters of the virtual photographing device, and playing the virtual image photographed by the virtual photographing device after the parameters are adjusted.
Specifically, the device responds to the action of adjusting the parameters of the virtual photographing device and plays the virtual image photographed by the virtual photographing device after the parameters are adjusted. The action of adjusting the parameters of the virtual photographing apparatus may be performed by the participants participating in the pre-performance event, and the parameters of the virtual photographing apparatus may include parameters of the camera body and parameters of the lens, wherein the parameters of the camera body may include pose information parameters and the like, and the parameters of the lens may include aperture and zoom range and the like.
The act of adjusting parameters of the virtual camera may include at least one of:
adjusting parameters of the virtual photographing apparatus by inputting parameter values in an input frame of a display screen; referring to fig. 3, parameter values may be input in an input box in the figure, and parameters of the virtual image capture device may be adjusted by adjusting the parameter values corresponding to the respective parameter items.
Displaying a control for adjusting parameters of the virtual photographing device in a display picture, and adjusting the parameters of the virtual photographing device by operating the control; the control may include a lever that can adjust the focal length of the virtual photographing apparatus, and is not particularly limited.
The focus of the virtual camera device may be adjusted by using an external device, for example, by dragging a sliding ball on a mouse moving control rod, and the method specifically includes: dragging the sliding ball on the control rod upwards to reduce the focal length of the virtual photographing device; the sliding ball on the control lever is dragged downwards to enlarge the focal length of the virtual photographing apparatus.
Adjusting parameters of the virtual photographing apparatus through an external device; wherein the peripheral is connected to the virtual photographing apparatus in advance. The peripheral device may be a joystick, the joystick is connected with the virtual camera in advance, and a corresponding relationship between a key of the joystick and a parameter of the virtual camera is established, for example, a lens direction of the virtual camera is adjusted by a direction key of the joystick, and a focal length of the virtual camera is adjusted by an L1 key or an R1 key of the joystick.
In this step, the parameters of the virtual image capturing device are directly adjusted by the peripheral device, in a manner of adjusting the parameters of the virtual image capturing device by the peripheral device. The above-mentioned mode of adjusting the parameters of the virtual photographing apparatus by operating the control is to control the control lever by the external device, and then adjust the parameters of the virtual photographing apparatus by the control lever, and indirectly adjust the parameters of the virtual photographing apparatus by the external device.
Responding to the action of adjusting the parameters of the virtual camera and playing the virtual image shot by the virtual camera after the parameters are adjusted, the method may specifically include the following steps:
and continuously playing the virtual image shot by the virtual shooting device before the parameters are adjusted. As shown in fig. 2, after the participant participating in the pre-performance event clicks a switch camera button (corresponding to the Footprint in fig. 2) at a time of 19 ms for 3 seconds, the current screen is switched to the screen of the virtual camera device that captures the virtual image shown in fig. 2. As shown in fig. 3, the virtual image capturing device for capturing a virtual image is displayed, and parameters of the virtual image capturing device may be displayed on the right side of fig. 3.
The virtual image captured by the virtual camera before the parameter adjustment can be continuously played at the time of 19 milliseconds in 3 seconds.
At the moment when the parameter adjustment is completed, playing the virtual image shot by the virtual shooting device after the parameter adjustment; or, the virtual image shot by the virtual shooting device after the parameters are adjusted is replayed from the initial playing time of the virtual image. In fig. 3, after the parameter adjustment is performed, at the time when the parameter adjustment is completed, for example, the playback time is 6 seconds and 20 milliseconds, the virtual image captured by the virtual image capturing device after the parameter adjustment is started from this time. If the participant participating in the pre-performance event wants to view the effect of the parameter adjustment at the time of 19 ms in 3 s, the playing progress can be manually adjusted to the time of 19 ms in 3 s for viewing, or the virtual image can be played again from the initial playing time and the virtual image played after the parameter adjustment can be viewed at the time of 19 ms in 3 s.
It should be noted that, after the parameters are adjusted, the virtual image is usually required to be played again from the beginning, so as to determine whether the played virtual image will be affected after the parameters are adjusted. Namely, the virtual image shot by the virtual shooting device after the parameters are adjusted is replayed from 0 second to 0 millisecond.
Responding to the action of adjusting the parameters of the virtual camera and playing the virtual image shot by the virtual camera after the parameters are adjusted, the method may specifically include the following steps:
and at the initial moment of adjusting the parameters, pausing the playing of the virtual image shot by the virtual shooting device. The playing of the virtual image captured by the virtual camera device may be automatically paused at the time when the terminal first detects the adjustment parameter, and fig. 4(a) -4 (b) are schematic diagrams of the virtual image before and after the adjustment parameter according to the embodiment of the present invention, as shown in fig. 4(a), which is 16 ms for 3 seconds.
And at the moment when the parameter adjustment is finished, continuously playing the virtual image shot by the virtual shooting device after the parameter adjustment is carried out. The completion of the parameter adjustment can be determined by setting a confirmation completion button, and as shown in fig. 4(b), the virtual image photographed by the virtual photographing apparatus after the parameter adjustment is continuously played from the time of 16 ms in 3 seconds, and the preview effect of the event activity before and after the parameter adjustment at the initial time can be compared more intuitively by comparing fig. 4(a) and 4 (b).
The playing of the virtual image may be controlled by a key arrangement, which is not shown in the figure. For example, when the playing key is in a stop state, the playing key is clicked once to play the virtual image; when the playing key is in a playing state, the playing key is clicked once, the virtual image is paused to be played, no matter what state the playing key is in, the playing key is clicked twice, and the virtual image is played from the initial playing moment.
The method may further comprise the steps of:
if the triggering action of pausing the playing of the virtual image shot by the virtual photographing device is detected, pausing the playing of the virtual image shot by the virtual photographing device and displaying the frame image at the current moment; as shown in fig. 4(a), when the playing time reaches 16 ms for 3 seconds, the participant participating in the pre-performance event finds that the shooting effect of the current virtual image is not good, and clicks the play key, the playing of the virtual image is suspended, and the frame image at the current time is shown in fig. 4 (a).
And in the parameter adjusting process, displaying the frame image at the current moment after the parameters are adjusted in real time.
Fig. 5(a) -5 (b) are screen shots of an embodiment of the present invention before and after parameter adjustment, where P in fig. 5(a) -5 (b) represents the virtual camera position, R represents the virtual camera rotation, S represents the virtual camera zoom, X, Y and Z represent the virtual camera three-dimensional space coordinates, respectively.
The participants participating in the pre-performance event click the switch camera key, that is, switch to the interface of fig. 3, and display the parameters of the current camera, and the parameters are as shown in fig. 5(a), the participants participating in the pre-performance event solve the problem that the shooting effect of the current virtual image is poor by adjusting the X value in R, and the adjusted parameters are as shown in fig. 5 (b). At this time, the frame image at the current time after the parameter adjustment is as shown in fig. 4(b), and the frame image at the current time after the parameter adjustment changes in real time every time the parameter is adjusted.
And if the triggering action of continuously playing the virtual image shot by the virtual photographing device is detected, continuously playing the virtual image shot by the virtual photographing device after the parameters are adjusted. And the participators participating in the pre-performance event activity find that the shooting effect of the frame image of the current virtual image reaches the expectation, click the play key again, and continue to play the virtual image shot by the virtual shooting device after the parameters are adjusted.
It should be noted that, if the participants participating in the pre-performance event find that the shooting effect of the frame image of the current virtual image does not reach the expectation, the parameters may be continuously adjusted until the shooting effect of the frame image of the current virtual image reaches the expectation, and the play key is clicked again to continuously play the virtual image shot by the virtual shooting device after the parameters are adjusted.
Fig. 6(a) -6 (b) are schematic diagrams of virtual images before and after adjusting the focal length based on the control stick according to the embodiment of the invention. After the step of "clicking the play button, and then pausing the playing of the virtual image" is performed, the virtual image shown in fig. 6(a) may be displayed, the participants participating in the pre-performance event may adjust the focal length through the control stick in the drawing, and the current virtual image may be displayed in real time according to the focal length adjustment value, and when the participants participating in the pre-performance event find that the shooting effect of the current virtual image reaches the expectation, the participants participating in the pre-performance event may not adjust the control stick, and the virtual image and the focal length adjustment value at this time are as shown in fig. 6 (b).
And when the participants participating in the pre-performance event need to watch the virtual image again from the initial playing time, double-clicking the playing key, and playing the virtual image from the initial playing time according to the parameters of the virtual camera at the moment.
According to the method for previewing the event activity provided by the embodiment of the invention, the action of responding to the parameter adjustment of the virtual photographic device is performed, and the virtual image shot by the virtual photographic device after the parameter adjustment is played, so that the parameter adjustment operation of the camera shooting the event activity video is not required to be performed when people arrive at the scene, and the previewing efficiency of the event activity is improved.
