Problems solved by technology

[0003] However, the 3D video production in the prior art requires the use of multiple cameras or professional panoramic cameras, and requires professional shooting, video editing, software splicing, interactive coding and other processes to complete the 3D video production.
This existing technology has at least the following problems: due to the high requirements for shooting equipment, the number of users is scarce, and it is not suitable for displaying 3D panoramas of commodities in systems such as online sales platforms, or VR experience based on specific commodities
However, this will reduce the participation of the first user, and the 3D video shooting and production process will also occupy a large amount of manpower and material resources in the system. In addition, the production efficiency will also be affected by factors such as postage. Therefore, It is difficult to actually promote

Embodiment 1

[0119] First, this embodiment 1 provides an image display method from the perspective of the second client, specifically, see Figure 4 , the method can include:

[0120] S401: The second client obtains the video file and the corresponding frame difference information;

[0121] Wherein, the video file may be a video file shot by the photographer using a single shooting device, and there are no restrictions on the model of the shooting device, shooting parameters, and the like. The corresponding relationship between the video file and the frame difference can be saved by the server, and the client can download it from the server when it needs to display. Among them, the frame difference value can be determined in a variety of ways, for example, it can be a pre-specified fixed value, or it can also be the frame difference determined for each video file according to the various methods described above. value, etc.

[0122] During specific implementation, the video file may cor...

Embodiment 2

[0135] The second embodiment corresponds to the first embodiment, and provides an image display method from the perspective of the server, see Figure 6 , the method can include:

[0136] S601: The server saves the video file and the corresponding frame difference information;

[0137] S602: When receiving the request for obtaining the video file sent by the second client, provide the video file and the corresponding frame difference information, and the client generates the first image and the second image when playing the video file. image, wherein each frame image included in the video file is determined as the first image, and the index value of each frame of the first image is offset by the frame difference value as the corresponding second image, and the The determined first image and the second image are respectively output to the first area and the second area of ​​the display window for display.

[0138] Regarding the above-mentioned second embodiment, related speci...

Embodiment 3

[0140] In the foregoing first and second embodiments, when the frame difference value corresponding to the video file is known, a processing method for displaying the 3D effect is provided based on the known information. However, the third embodiment introduces how to determine the frame difference value corresponding to the video file. Specifically, the third embodiment firstly provides a video file processing method from the perspective of the server, see Figure 7 , the method can include:

[0141] S701: The server receives a video file shot by a monocular camera device, and obtains shooting parameter information of the camera device;

[0142] In the third embodiment, the server can use the aforementioned automatic method to determine the frame difference. In this case, the first client only needs to submit the video file to the server. Parameter-related information enables the server to obtain specific shooting parameters. Among them, if the shooting device is a device ...

Abstract

The embodiment of the present application discloses image display and video file processing methods and devices, wherein the method includes: the second client obtains the video file and the corresponding frame difference information; creates an image display window, and the display window includes the first An area and a second area, wherein the first area is used to display the left image, and the second area is used to display the right image; the first image and the second image are determined, wherein each frame included in the video file is The image is determined as the first image, and the index value of each frame of the first image is offset by the frame difference value as the corresponding second image; the determined first image and the second image are respectively output to the first area and the second area for stereoscopic display. Through the embodiment of the present application, it is beneficial to carry out popularization and application, obtain more users and richer video files.

Description

technical field [0001] The present application relates to the technical field of image processing, in particular to methods and devices for image display and video file processing. Background technique [0002] With the development of the mobile Internet, mobile terminal devices such as mobile phones have already supported the vast majority of multimedia forms, such as gif pictures, videos, etc. While the richness of content has increased, users have become more interactive and three-dimensional multimedia The form shows a stronger appeal. Based on this appeal, in some online sales systems, a panorama display function of products with 3D stereoscopic effects, or a VR (virtual reality) experience hall and other functions are provided. Through specially produced 3D stereoscopic interactive video, combined with 3D glasses, VR glasses and other equipment, users can watch 3D videos with depth information, and obtain a more immersive experience similar to 3D movies. [0003] How...
