According to the video processing method, the video processing device and the electronic equipment, the first video shot by the shooting equipment and the second video shot by the space flight view angle are synthesized mainly through the multi-view video processing means, so that the video from the departure place to the shooting place is obtained. Through the synthesis processing of the multi-section video, pictures with multiple visual angles can be displayed in a single video, so that a strong visual impact is brought to a user. In addition, a third video from the interstellar departure place to the departure place position can be generated according to the selected type of the interstellar departure place, the first video, the second video and the third video are synthesized, and a final video from the interstellar departure place to the shooting place is generated, so that videos with rich vision and stronger narrative property and continuity can be generated, and the watching experience of a user is improved.

Referring to fig. 1, fig. 1 is a flowchart of a video processing method according to an embodiment of the present application. As shown in fig. 1, the method includes:

s101: acquiring a first video shot by an image pickup device, and acquiring a shooting place position corresponding to the first video;

s102: acquiring a departure place position selected by a user, and acquiring a second video of a space flight view angle from the departure place position to the shooting place position;

s103: and synthesizing the first video and the second video to generate a synthesized video.

According to the method and the device, the video material of the shooting place can be shot through the shooting equipment to serve as the first video, and the corresponding positioning data of the first video are obtained while the first video is acquired to determine the position of the shooting place. And acquiring satellite pictures from the departure place to the shooting place according to the type of the selected departure place, and processing the satellite pictures to generate a second video of the space flight view angle from the departure place to the shooting place. And combining the first video and the second video to enable the single video to display pictures with multiple visual angles, thereby obtaining the generated combined video.

Specifically, the embodiment may capture, by the image capturing apparatus, the video material of the capturing place concerned as the first video, and may also capture the position information of the capturing place corresponding to the first video. It can be understood that, at present, a lot of camera devices can additionally acquire the position information of the relevant shooting place when shooting videos, taking an unmanned aerial vehicle as a camera device to shoot videos as an example, when a user uses the unmanned aerial vehicle to shoot video materials at the shooting place as a first video, a GPS receiving module built in the unmanned aerial vehicle can receive signals transmitted by satellites, calculate the position of the unmanned aerial vehicle by utilizing a triangle positioning principle, namely acquire longitude and latitude coordinate information of the shooting place, and then determine the optimal shooting place position corresponding to the first video according to the acquired longitude and latitude coordinate information. When the longitude and latitude coordinate information is multiple sets of coordinates, that is, when the shooting locations are multiple, shooting time lengths corresponding to the shooting locations can be obtained according to the shot first video, and the shooting location with the longest shooting time length is used as the optimal shooting location corresponding to the first video.

In addition, the method for acquiring the shooting location corresponding to the first video in the present embodiment includes, but is not limited to, the above method. For example, a landmark, a feature point or a map of the shooting place can be identified by a camera or a sensor mounted on the unmanned aerial vehicle by utilizing image processing and a computer vision algorithm so as to determine the position of the unmanned aerial vehicle, thereby acquiring the position information of the shooting place. For example, taking a camera as an image capturing apparatus to capture a video, metadata is additionally acquired when a user captures a video material at a capturing place using the camera, wherein the metadata may contain information about the capturing place, such as latitude and longitude coordinates, a geographic mark, or a place name, and the position of the capturing place is acquired by reading the metadata of the video.

The embodiment can enable the image pickup device to shoot video materials through the GPS receiving module built in the image pickup device, and can provide more accurate and representative shooting place position information.

Wherein, as shown in fig. 2, the step of obtaining the departure place position selected by the user and obtaining the second video of the space flight view angle from the departure place position to the shooting place position includes:

s201: acquiring satellite pictures from the departure place to the shooting place;

s202: acquiring shooting heights corresponding to the shooting place positions;

s203: determining a type of the departure location;

s204: and processing the satellite picture according to the shooting altitude and the type of the starting place position to generate a second video of a space flight view angle from the starting place position to the shooting place position.

First, in the present embodiment, a satellite picture from a departure location to a shooting location is acquired based on acquired position information of the shooting location and a location of the departure location selected by a user. It can be understood that taking the unmanned aerial vehicle as the image capturing device for example, the built-in image capturing module of the unmanned aerial vehicle obtains a large number of satellite pictures from the departure place to the shooting place from the open API interface provided by the satellite map suppliers (such as hundred degrees, germany, google, mapBox and the like) through the image capturing algorithm. According to the difference of the shooting height corresponding to the shooting place position and the type of the departure place position selected by the user, satellite pictures of different types and representing all zoom levels above the shooting height can be obtained. It can be understood that taking google map platform as an example, when a user shoots a first video at a height of 1200 meters on the ground through an unmanned aerial vehicle, a zoom level corresponding to a viewpoint height higher than that of the first video is obtained through a map parameter lookup table, and the corresponding zoom level is 19 levels even though a viewpoint height of 1500 meters is used.

If the type of the departure place selected by the user is space, 20 satellite pictures from 0 to 19 levels of GPS coordinates of the shooting place are acquired through an API interface of the satellite map provider and recorded as a vertical picture sequence 1. If the type of the departure place selected by the user is the ground, the zoom level is fixed (level 2 or above), all satellite pictures from the appointed place to the shooting place on the ground are acquired in a certain step length through an API interface of a satellite map provider and are recorded as a horizontal picture sequence 1, and all satellite pictures from the fixed zoom level to level 19 are acquired and recorded as a vertical picture sequence 2. In addition, it is necessary to set the resolution of the satellite picture according to the resolution of the first video, such as 1920×1080, while acquiring the satellite picture.

And secondly, screening out satellite pictures meeting the conditions from all the acquired satellite pictures from the starting place to the shooting place according to the shooting height corresponding to the shooting place and the type of the starting place position selected by the user, and processing the acquired satellite pictures meeting the conditions to obtain a second video representing the space flight view angle from the starting place position to the shooting place position.

And when the type of the departure place is space, processing the satellite picture according to the shooting altitude and the type of the departure place to generate a second video of a space flight view angle from the departure place to the shooting place. It can be understood that when the type of the departure place is space, that is, when the departure place is space above the earth, the first height greater than the shooting height is determined according to the shooting height, for example, when the shooting height of the user using the unmanned aerial vehicle to shoot the video material is 1200 meters above the ground, the height (greater than the shooting height) greater than 1500 meters above the ground is selected as the first height, and the first zoom level corresponding to the first height is obtained through the map parameter lookup table, that is, the corresponding zoom level is 19. Then, from among the plurality of obtained satellite pictures of each zoom level, all satellite pictures of 0 to 19 levels corresponding to the GPS coordinates of the shooting location and the first zoom level (19 levels) are found as satellite pictures from space above earth to the shooting location, i.e., vertical picture sequence 1, and then the filtered vertical picture sequence is converted into video.

It will be appreciated that when the origin is space, i.e. space above earth, the differentiation between vertical picture sequences is reduced by using picture scaling for frame insertion. For example, as shown in fig. 3 (a), adjacent zoom levels L with sizes P are selected _n And L _n-1 The satellite picture of the satellite is obtained by searching a satellite picture parameter table to obtain the spatial resolution (or scale) S of two scaling scales _n And S is _n-1 The distance pixel region of the high zoom level in the low zoom level, i.e., the red frame region size P 'in fig. 3 (b), can be calculated, where P' = (S) _n-1 /S _n ) X P. It can be appreciated that, for example, a satellite picture with a size of 1920×1080, and a spatial resolution of 4 meters and 2.15 meters corresponding to 16-level scaling and 15-level scaling, respectively, then P' = (S) _n-1 /S _n ) The x P formula can calculate the range pixel region of the 16-level satellite picture in the 15-level satellite picture, i.e., 1032 x 580. In addition, as shown in fig. 3 (c), between the P' and the P size, the satellite picture is gradually cut by the set pixels to generate a plurality of pictures, the sizes of the generated plurality of pictures are all scaled to P, and then scaling operation is performed on the satellite pictures of all adjacent scaling levels, so as to complete all the frame inserting pictures. And finally, all the processed satellite pictures are encoded into videos. In addition, by setting the number of frames and codes at the time of converting the processed satellite picture into video to the same value as those of the first video, the time consumption of additional transcoding can be reduced or avoided at the time of video composition, the picture conversion into video including but not limited toNot limited to the following methods, such as OpenCV, or other third party video tools, and may add smoothness when converting a picture into video by adding related inter-frame optimization algorithms (such as optical flow, AI-interpolation, motion blur, etc.).

According to the embodiment, the satellite pictures are processed to generate the second video of the space flight view angle from the space above the earth to the shooting place, so that the user can feel the view angles of the ground and the space at the same time, and a shocking visual effect is brought to the user.

And when the type of the departure place is the ground, processing the satellite picture according to the shooting altitude and the type of the departure place so as to generate a second video of a space flight view angle from the departure place to the shooting place. It can be understood that when the type of the departure place is the ground, that is, when the departure place is each city or a standard point on the earth, a first height greater than the shooting height is determined according to the shooting height, for example, when the shooting height of a user using an unmanned aerial vehicle to shoot video material is 200 meters above the ground, a height 1500 meters above the ground (higher than the shooting height) is selected as the first height, and a first zoom level corresponding to the first height is obtained through a map parameter lookup table, that is, the corresponding zoom level is 19. And acquiring a horizontal picture sequence 1 from the ground to the shooting place from a plurality of acquired satellite pictures at each level based on a preset fixed zoom level (level 2 or more), and acquiring all satellite pictures from the fixed zoom level to level 19, namely a vertical picture sequence 2. And then converting the horizontal picture sequence and the vertical picture sequence 2 after screening into videos, namely generating a second video of the space flight view angle which is firstly shifted to the shooting place from a certain city on the ground and then vertically zoomed to the designated shooting height. If the departure point is a city or a standard point on the ground, the video is synthesized using the horizontal picture sequence 1 without performing the scaling operation, and the scaling operation when the video is synthesized using the vertical picture sequence 2 is the same as the scaling operation described above.

According to the embodiment, the satellite pictures are processed to generate the second video of the space flight view angle from each city or the marked point to the shooting place on the ground, so that a user can feel an air journey from the departure place to the shooting place, and the immersion of the user can be enhanced through view angle switching and flight effects.

In some embodiments, a third video may also be generated from the interstellar departure to the departure location by the user-selected interstellar departure. It will be appreciated that the interplanetary origin comprises a partial cosmic star name, and that a user may select one of the star as the interstellar origin, one of the star as the origin, and a plurality of the star as the passthrough. For example, the user can select the Galaxy as the interstellar departure place and the solar system as the passing place, and the first visual angle animation video from the Galaxy to the passing solar system reaching the departure place is automatically generated as the third video through the CGI animation technology. And then, synthesizing the third video with the first video and the second video to generate a final video. It will be appreciated that the third video generated is spliced with the first video and the second video in sequence to generate the final complete space flight travel video from the interstellar departure point to the shooting point. In addition, when the three video segments are spliced in sequence, a related transition method, such as a method provided by adding a cut special effect or other third party software, can be added to enable the synthesized final video to be smoother, so that a multi-view video with stronger continuity and narrative is created.

Optionally, the synthesizing the third video with the first video and the second video to generate a final video includes: responding to a virtual interstellar departure place, a virtual departure place position and a virtual shooting place position selected by a user on a display interface, and acquiring a first video, a second video and a third video corresponding to the virtual interstellar departure place, the virtual departure place position and the virtual shooting place position; and responding to the synthesis operation of the user on the display interface, and generating the synthesized video of the first video, the second video and the third video.

The display interface may be in the form of a remote control, a mobile phone application, or other interactive interface. For example, when the display interface is a remote controller, the image capturing apparatus may be provided with a wireless remote controller having a display screen, and the user may select the virtual interplanetary departure place, the virtual departure place position, and the virtual shooting place position by pressing a button on the remote controller to transmit corresponding instructions, thereby acquiring the first video, the second video, and the third video provided by the image capturing apparatus corresponding to the virtual interplanetary departure place, the virtual departure place, and the virtual shooting place position, and may also compose the acquired first video, second video, and third video into new videos through a composition button on the remote controller. In addition, the quality of the synthesized video can be higher by performing operations such as smoothing, adding a cut-off special effect, video editing and the like in the video synthesis process through a beautifying button on the remote controller. For example, when the display interface is a mobile phone application, the user may connect with the image capturing device by installing the mobile phone application, and the mobile phone application provides a graphical interface, through which the user may select a type of departure place, a video processing mode, monitor and control a state of the image capturing device in real time, and so on.

In this embodiment, a display interface is set, and the display interface is connected with the image capturing device, so as to receive an instruction input by a user, including selecting a departure type and a video processing mode, thereby bringing user interaction, customizing videos, flexibility and diversity to the image capturing device, and increasing user experience.
