Problems solved by technology
However, for mobile terminals, it is impossible to capture multiple pictures of the same scene from different angles at the same time, and then synthesize a 3D stereoscopic image, and the 3D effect synthesis method based on the depth map is complex and requires a large amount of system resources. The terminal also fails to implement
Moreover, these two methods do not distinguish between the foreground area and the background area during the image conversion process, and the quality of the stereoscopic image after synthesis is degraded. Therefore, the existing methods of converting common resources into stereoscopic resources are difficult to implement on mobile terminals. Using Very inconvenient and doesn't convert well

The invention provides a method and a device for generating a stereoscopic video file. The method comprises the following steps of: analyzing a video file to obtain a plurality of image frames of the video file, and selecting a reference image frame among the plurality of image frames; determining a foreground area and a background area of the image frame behind the reference image frame according to the reference image frame; carrying out image processing on the foreground area and the background area respectively to obtain a foreground image and a background image; synthesizing the foreground image and the background image into a stereoscopic image; and generating a stereoscopic video file according to a plurality of stereoscopic images corresponding to the plurality of image frames, and outputting the stereoscopic video file. According to the method disclosed by the embodiment of the invention, the requirements of users on stereoscopic resources are met by converting common resources into the stereoscopic resources, the stereoscopic video file generated by using the method is high in image quality, simple in algorithm and easy to realize, so that a large amount of system resources can be saved, the requirements on the performance of the terminal are reduced, and the user experience is good.
Description
technical field [0001] The invention relates to the technical field of image processing, in particular to a method and device for generating stereoscopic video files. Background technique [0002] With the development of three-dimensional technology, the existing resources with three-dimensional effects are difficult to meet the increasing needs of users. Therefore, it is urgent to convert traditional two-dimensional resources with rich resources into three-dimensional resources to solve the problem of lack of three-dimensional resources. [0003] At present, ordinary two-dimensional resources can be converted into three-dimensional three-dimensional resources through a depth map-based three-dimensional effect synthesis method or a method of synthesizing a three-dimensional effect picture from multiple multi-dimensional pictures. However, for mobile terminals, it is impossible to capture multiple pictures of the same scene from different angles at the same time, and then syn...
