[0052] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0053] See Figure 1 , which is a schematic diagram of an application scenario provided by an embodiment of the present invention.

[0054] As Figure 1 shown, the application scenario is a schematic diagram of the video shooting process replication process, including: virtual scene 100 and window 101. The virtual scene 100 is a virtual scene simulated according to the real shooting scene of the original video, and the virtual objects included therein can be simulated according to the objects in the real shooting scene. For example, the virtual scene 100 may include, but is not limited to: person 105, person 106, tables and chairs 107.

[0055] In the embodiments of the present invention, the same number of virtual camera positions as the number of shooting positions of the original video (i.e., the real camera positions used in the real shooting process) are set in the virtual scene 100. For example, virtual camera positions 102, 103, and 104 are set in the virtual scene 100. Moreover, the virtual camera positions 102, 103, and 104 can all move in the virtual scene 100 to obtain the images of the virtual scene 100 from different perspectives.

[0056] The window 101 is used to play the images from the perspectives corresponding to the virtual camera positions 102, 103, or 104.

[0057] Based on Figure 1 the application scenario shown in the example, when playing the original video and applying the technical solution provided by the present invention, it is possible to make the virtual camera positions 102, 103, or 104 move in the virtual scene 100 as the original video is played, so as to restore the movement process of each real camera position when shooting the original video. In this way, students learning video shooting can better understand the video shooting process.

[0058] The following further explains the method for replicating a video shooting process provided by the present invention with specific embodiments in conjunction with the accompanying drawings. The embodiments do not constitute a limitation on the embodiments of the present invention.

[0059] See Figure 2 , which is a flowchart of an embodiment of a method for replicating a video shooting process provided by an embodiment of the present invention. As Figure 2 shown, the process may include the following steps:

[0060] Step 201, play the target video.

[0061] Step 202, during the process of playing the above-mentioned target video, determine the first shooting position corresponding to the first video frame, where the first video frame is the currently played video frame.

[0062] The following provides a unified description of steps 201 and 202:

[0063] The above-mentioned target video refers to a completed video that has been shot and edited.

[0064] In practice, when playing the target video, the video playback software can play at the granularity of video frames, that is, after playing one video frame, the video playback software plays the next video frame.

[0065] In one embodiment, during the process of playing the above-mentioned target video, first determine the shooting position corresponding to the currently played video frame (hereinafter referred to as the first video frame for convenience of description). Here, the shooting position refers to the actual shooting position, and hereinafter referred to as the first shooting position for convenience of description).

[0066] Optionally, search for a preset editing schedule according to the shooting time of the above-mentioned first video frame. The editing schedule includes the corresponding relationship between the shooting time period of the edited video segment and the shooting position of the edited video segment, and obtain the first edited video segment to which the first video frame belongs. Then, determine the shooting position of the first edited video segment as the first shooting position corresponding to the first video frame.

[0067] For example, as shown in Table 1 below, it is an example of the above-mentioned preset editing schedule:

[0068] Table 1

[0069] Shooting position serial number Effective start time / min Effective end time / min 1 0 5 2 5 8 3 8 12 4 12 36 5 36 50 6 50 80

[0070] As can be seen from Table 1 above, each shooting position can correspond to a valid start time and a valid end time. Among them, the time period between the valid start time and the valid end time is the shooting time period of the edited video segment.

[0071] Based on the example in Table 1 above, assume that the shooting time of the first video frame, that is, the current time when the target video is being played, is the 6th minute. At this time, according to the shooting time of the first video frame, search for the preset clip schedule shown in Table 1 above. As can be seen from Table 1 above, the time period where the 6th minute is located is within the time period of 5 - 8 minutes, and the shooting camera position corresponding to this time period is the 2nd shooting camera position. Thus, it can be determined that the first shooting camera position corresponding to the first video frame is the 2nd shooting camera position.

[0072] Step 203: Determine the target virtual position corresponding to the first virtual camera position in the target virtual scene. The target virtual scene is the virtual scene corresponding to the shooting scene of the target video, and the first virtual camera position is the virtual camera position corresponding to the first shooting camera position in the target virtual scene.

[0073] In one embodiment, after determining the first shooting camera position corresponding to the first video frame in the target virtual scene, the target virtual position where the first virtual camera position is located when shooting the first video frame can be determined.

[0074] Specifically, first, obtain the first movement trajectory of the first virtual camera position in the target virtual scene. The first movement trajectory is constructed based on the movement trajectory of the first shooting camera position during the shooting process of the target video.

[0075] After that, based on the first movement trajectory and the shooting time of the first video frame, determine the target virtual position corresponding to the first virtual camera position in the target virtual scene.

[0076] As a possible implementation manner, when constructing the first movement trajectory of the first virtual camera position in the target virtual scene, for the first shooting camera position corresponding to the target video, in response to the received movement operation, move the first virtual camera position corresponding to the first shooting camera position in the target virtual scene, and record the first movement trajectory of the first virtual camera position in the target virtual scene.

[0077] Among them, in response to the received movement operation, it may include: Professional technicians, according to the pre-obtained movement trajectory of the first virtual camera position, move external devices such as a mouse or a joystick, so that the execution entity of the present invention can, in response to the received movement operation, move the first virtual camera position corresponding to the first shooting camera position in the target virtual scene, and record the first movement trajectory of the first virtual camera position in the target virtual scene.

[0078] Step 204: In the target virtual scene, move the first virtual camera position from the current position to the target virtual position.

[0079] In one embodiment, after determining the target virtual position of the first virtual machine position, moving the first virtual machine position from the current position to the target virtual position can restore the shooting process of each video frame when shooting the target video.

[0080] For ease of understanding the embodiments of the present invention, the following takes Figure 1 the application scenario shown as an example to specifically describe the embodiments of the present invention.

[0081] Suppose Figure 1 the virtual scene shown is the above-mentioned target virtual scene. When playing the target video, assume that now the second video frame of the target video is being played. By searching the preset time schedule, it can be determined that the corresponding shooting position of the second frame is the first shooting position, and the virtual machine position corresponding to the first shooting position in the target virtual scene is the virtual machine position 102.

[0082] Continue to assume that through the constructed movement trajectory of the virtual machine position 102 and the shooting time of the current second video frame, it is determined that point C in the figure is the target virtual position of the virtual machine position 102. Then, execute step 204 to move the virtual machine position 102 from the current position to point C. During the process of moving the virtual machine position 102 to point C in the figure, it is to restore the shooting process of the second video frame of the target video.

[0083] The technical solution provided by the embodiments of the present invention, during the process of playing the target video, determines the first shooting position corresponding to the first video frame, where the first video frame is the currently played video frame; then, determines the target virtual position corresponding to the first virtual machine position in the target virtual scene, where the target virtual scene is the virtual scene corresponding to the shooting scene of the target video, and the first virtual machine position is the virtual machine position corresponding to the first shooting position in the target virtual scene; in the target virtual scene, moves the first virtual machine position from the current position to the target virtual position. By determining the shooting position of the current video frame and the virtual machine position in the virtual scene corresponding to the target video during the process of playing the target video, and moving the virtual machine position from the current position to the determined target virtual position, the shooting process of the current video frame is restored during the movement of the virtual machine position, achieving the ability to switch the corresponding shooting position in real time when playing the video, thereby realizing the restoration of the video shooting process and improving the understandability of film and television teaching.

[0084] See Figure 3 , which is a flowchart of an embodiment of another method for replicating a video shooting process provided by the embodiments of the present invention. As Figure 3 shown, this process may include the following steps:

[0085] Step 301, play the target video.

[0086] Step 302: During the process of playing the above-mentioned target video, determine the first shooting position corresponding to the first video frame, where the first video frame is the currently played video frame.

[0087] Step 303: Determine the target virtual position corresponding to the first virtual position in the target virtual scene. The target virtual scene is the virtual scene corresponding to the shooting scene of the above-mentioned target video, and the first virtual position is the virtual position corresponding to the first shooting position in the above-mentioned target virtual scene.

[0088] Steps 301 to 303 have been described in detail in the above-mentioned steps 201 to 203, and will not be elaborated here.

[0089] Step 304: Determine whether the current position of the first virtual position is the same as the target virtual position. If so, execute Step 306; if not, execute Step 305.

[0090] Step 305: In the above-mentioned target virtual scene, move the first virtual position from the current position to the target virtual position, and then execute Step 307.

[0091] Step 306: After the above-mentioned first video frame is played, continue to play the next video frame, and use the next video frame as the first video frame to execute Step 302 until the last video frame of the above-mentioned target video is played, and the process ends.

[0092] The following provides a unified description of Steps 304 to 306:

[0093] In one embodiment, after determining the target virtual position of the first virtual position, it is possible to first determine whether the current position of the first virtual position is the same as the target virtual position. If they are the same, it means that the first video frame and the previous video frames belong to the same shooting time period, and at this time, the first virtual position can be for static shooting, so no movement operation needs to be performed on the first virtual position.

[0094] On the contrary, if the current position of the first virtual position is not the same as the target virtual position, move the first virtual position from the current position to the target virtual position.

[0095] After the above-mentioned first video frame is played, continue to play the next video frame, and use the next video frame as the first video frame to execute Step 302 until the last video frame of the above-mentioned target video is played.

[0096] Step 307: During the process of moving the first virtual position from the current position to the target virtual position, obtain the picture of the above-mentioned target virtual scene from the perspective corresponding to the first virtual position.

[0097] Step 308: Output the above-mentioned picture through the visualization interface.

[0098] The following is a unified description of Step 307 and Step 308:

[0099] Taking Figure 1 the application scenario shown as an example, during the process of the first virtual machine position (such as virtual machine position 102) moving from the current position to point C in the figure, the picture of the target virtual scene from the perspective corresponding to the first virtual machine position can be obtained. Then, through the visualization interface, such as Figure 1 the picture is output in window 101 shown. Through this kind of processing, while restoring the video shooting process, the virtual machine position can be switched in real time, and the picture from the perspective corresponding to the virtual machine position can be displayed, so as to facilitate students to more clearly understand the video shooting process and improve the understandability of teaching.

[0100] In the technical solution provided by the embodiment of the present invention, by determining whether the current position of the first virtual machine is the same as the target virtual position, if they are the same, then after the current video frame is played, the next video frame is played; if they are not the same, then the first virtual machine is moved from the current position to the target virtual position, and the picture of the target virtual scene from the perspective corresponding to the first virtual machine position is obtained, and the picture is output through the visualization interface. By judging whether to move the first virtual machine position, and during the process of moving the first virtual machine position to the target virtual machine position, obtaining the picture of the target virtual scene from the perspective corresponding to the first virtual machine position, so as to realize that when playing a video, the corresponding shooting position and the shooting picture of the virtual machine position can be switched in real time, thereby realizing the restoration of the video shooting process and improving the understandability of film and television teaching.
