In view of the above problems, a method for generating 360-degree panoramic images of an object is provided.
Disclosure of Invention
The present invention is directed to a method for generating an object 360-degree panoramic image, so as to solve the problems mentioned in the background art.
In order to achieve the purpose, the invention provides the following technical scheme:
a method for generating 360-degree all-round images of an object comprises the following operation steps:
step 1: acquiring video information of a circle outside a target by a photographing terminal around the target in a video mode;
step 2: intercepting a plurality of pictures according to the time sequence of the video acquired in the step 1, comparing the acquired adjacent pictures, and extracting the picture without superposition to obtain a target picture;
and step 3: and sequencing the intercepted pictures according to the time sequence in the video where the pictures are located to generate a picture set, wherein each picture has an independent ID value, and the plurality of pictures are displayed in a 360-degree circular view through a display module.
As a further scheme of the invention: the shooting angle in the step 1 isAre relatively fixedIn (1).
As a further scheme of the invention: the shooting time in the step 1 is arbitrary, but the effect is better if the video duration is between 15 seconds and 90 seconds.
As a further scheme of the invention: and (3) if the time length of the video collected in the step (2) exceeds 30 seconds, capturing one picture per second, comparing each picture with the pictures captured before and after the adjacent time point, and extracting all the pictures which are not overlapped to obtain 360-degree coherent pictures of the object.
As a further scheme of the invention: and 2, if the time length of the video collected in the step 2 is not more than 30 seconds, dividing the video into a plurality of equally-divided time nodes by taking the video frame as a unit, intercepting one picture by each time node, comparing the picture with the pictures intercepted by the adjacent time nodes, and extracting the pictures without superposition to obtain a plurality of consecutive pictures.
As a further scheme of the invention: the number of pictures extracted is 24 or 36 or 72.
As a still further scheme of the invention: the photographing terminal in the step 1 is a mobile phone, a tablet computer, a video camera, a camera or any other internet application terminal with a camera device.
As a still further scheme of the invention: and 3, the display module is a browser or an APP capable of displaying pictures.
Compared with the prior art, the invention has the beneficial effects that: according to the measurement and calculation, a 360-degree all-round-looking interactive image can be generated only in about 10-15 minutes by manually shooting pictures in the prior art, and the improved mode of shooting videos around objects can be generated only in less than 1 minute, so that a user can repeatedly adjust shooting details, and an ideal interactive image can be shot in a short time.
The original pictures are obtained by adopting a manual picture-by-picture mode, the due consistency is difficult to keep among the pictures one by one, and the dislocation phenomenon is easy to occur. After improvement, the mode of shooting the video is combined with the dynamic algorithm to intercept the picture to automatically generate the interactive image, so that the continuity is better, the dislocation phenomenon can not occur, and the interactive experience is smoother.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the following embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example 1
In the embodiment of the invention, the method for generating the 360-degree all-round view image of the object comprises the following operation steps:
step 1: acquiring video information of a circle outside a target by a photographing terminal around the target in a video mode;
step 2: intercepting a plurality of pictures according to the time sequence of the video acquired in the step 1, comparing the acquired adjacent pictures, and extracting the picture without superposition to obtain a target picture;
and step 3: and sequencing the intercepted pictures according to the time sequence in the video where the pictures are located to generate a picture set, wherein each picture has an independent ID value, and the plurality of pictures are displayed in a 360-degree circular view through a display module.
As a further scheme of the invention: the shooting angle in the step 1 is fixed.
As a further scheme of the invention: the shooting time in the step 1 is arbitrary, but the effect is better if the video duration is between 15 seconds and 90 seconds.
As a further scheme of the invention: and (3) if the time length of the video collected in the step (2) exceeds 30 seconds, capturing one picture per second, comparing each picture with the pictures captured before and after the adjacent time point, and extracting all the pictures which are not overlapped to obtain 360-degree coherent pictures of the object.
