Problems solved by technology

[0004] However, the way the user manually sets the video format requires the user to manually participate when switching between different video formats. The flexibility is too poor, it is extremely inconvenient to use, and the experience is poor; the method of automatically recognizing the video format, because it can only recognize the left and right format videos program, the recognition format is too single, and the accuracy rate is not high, which cannot meet the application scenarios of multiple video format recognition

Embodiment 1

[0035] figure 1 It is a flow chart diagram of a method for identifying a video format provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation where the playback format of the current video is determined, and the video is played and managed according to the determined format. This method can be performed by the video format recognition means, which can be implemented in the form of software and / or hardware.

[0036] Such as figure 1 Described, the method of the embodiment of the present invention comprises:

[0037] S110. Obtain a target image in the video to be played.

[0038] It should be noted that when playing a video, a corresponding playback device and a display device are required, that is to say, a playback system and a 3D display device are required. Wherein, the video playing system can be a computer or a dedicated video decoding and playing device, and it can be understood that the video playing system only needs to be ab...

Embodiment 2

[0053] On the basis of the above embodiments, at least one image recognition algorithm is sequentially used to process the target image according to a preset execution sequence, and the Sobel edge detection algorithm may be preferentially used to process the target image. image 3 It is a schematic flowchart of processing a target image by using the Sobel edge detection algorithm provided by Embodiment 2 of the present invention.

[0054] Such as image 3 Described, the method of the embodiment of the present invention comprises:

[0055] S310. Acquire a target image of a video to be played.

[0056] Wherein, the target image may be the first frame image of the video to be played. If the first frame image is a completely black image, then it is determined that the first frame image is an invalid image, and the next frame image of the first frame image is obtained, and the next frame image as the target image.

[0057] S320. Process the target image by using a Sobel edge det...

Embodiment 3

[0077] When the target image of the video to be played is obtained, the background color of the target image may be relatively close or it is difficult to judge whether there is a dividing line in the target image through the Sobel edge detection algorithm due to the image itself, the segmented image can be restored, of course It is also possible to obtain the target image directly without restoration, and use the histogram statistical algorithm to process the restored image. For the specific processing method, please refer to Figure 4 . Figure 4 It is a schematic flow chart of processing a target image using a histogram statistical algorithm provided by Embodiment 3 of the present invention.

[0078] Such as Figure 4 Described, the method of the embodiment of the present invention comprises:

[0079] S410. Using the Sobel edge detection algorithm to calculate the gray value of the pixels on both sides adjacent to the dividing line without any jump.

[0080] On the basis o...

Abstract

The invention discloses a method and a device for recognizing a video format, equipment and a storage medium. The method comprises: acquiring a target image in a video to be played; sequentially usingat least one image recognition algorithm to process the target image according to a preset execution sequence to obtain a processing result; determining a format of the video to be played according to the processing result, wherein the image recognition algorithm comprises a Sobel edge detection algorithm, a histogram statistical algorithm, an image gray processing algorithm, an image Gaussian filtering algorithm, an image contour extraction algorithm, a graph Hu invariant moment comparison algorithm and a multi-region central moment algorithm. The technical solution provided by the embodiments of the invention realizes the technical effects of automatically recognizing all the 3D video formats, using at least one image recognition method to recognize the image in the process of recognition, improving the accuracy of the determination result of the video format, and saving labor cost.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of video format identification, and in particular, to a video format identification method, device, device, and storage medium. Background technique [0002] During the playback and display process of video program sources (including 3D and 2D programs), it is necessary to inform the playback system (including interlaced rendering and display devices) of the format of the current program, so that subsequent devices can use different processing methods according to different formats to achieve optimal performance. 3D display effect. [0003] At present, when the 3D playback system outputs 3D video, there are basically two methods for setting the video format. One is the user interaction method. The user informs the playback system of the video format through the input device (remote control, keyboard and other external devices) to operate the interactive interface options, and the playb...
