6. The method according to claim 4, wherein before the step of detecting a relative change in position of the common subject in the first picture and the second picture, the method further comprises:
acquiring the value of the shooting time interval delta t of the first picture and the second picture;
judging whether the value of the delta t is within a preset time interval range or not;
and if the value of the delta t is within a preset time interval range, executing the step of detecting the relative position change of the common shot object in the first picture and the second picture.
7. The method according to claim 1, wherein the method for detecting the relative position change of the common object in the first picture and the second picture comprises:
establishing a first coordinate system by taking the central point of the first picture as a first coordinate origin, and establishing a second coordinate system by taking the central point of the second picture as a second coordinate origin;
determining a first coordinate set of a shot object in a first coordinate system in the first picture;
determining a second coordinate set of the shot object in a second coordinate system in the second picture;
judging whether the first coordinate set and the second coordinate set have differences or not;
if the first coordinate set and the second coordinate set are different, determining that the relative position of the common shot object in the first picture and the second picture is changed;
otherwise, judging that the relative position of the common shot object in the first picture and the second picture is not changed.
8. The method according to claim 1, wherein the method for detecting the relative position change of the common object in the first picture and the second picture comprises:
selecting a first characteristic point around a shot object in the first graph;
selecting a second feature point around the shot object in the second image;
judging whether the first characteristic point and the second characteristic point have difference or not;
if the first characteristic point and the second characteristic point are different, determining that the relative position of the common shot object in the first picture and the second picture is changed;
otherwise, judging that the relative position of the common shot object in the first picture and the second picture is not changed.
9. The method of claim 1, wherein after the step of generating a video based on the first key frame, intermediate frames, and second key frames, the method further comprises:
analyzing a current video topic of the currently generated video;
selecting a special effect corresponding to the current video theme from a preset special effect database;
based on the selected special effect, carrying out special effect processing on the generated video;
the special effect database comprises at least one special effect, and each special effect corresponds to at least one video theme.
10. A terminal device for picture generation video, wherein when generating a picture into video, the terminal device is configured to:
acquiring a first picture and a second picture;
taking the first picture as a first key frame and the second picture as a second key frame;
detecting the relative position change of a common shot object in the first picture and the second picture;
supplementing an intermediate frame between the first key frame and the second key frame based on the relative position change of the shot object;
generating a video based on the first key frame, the intermediate frame, and the second key frame.
