Problems solved by technology

[0002] The existing algorithm does not provide a method for identifying 3D video and non-3D video. People need to manually open the video to play, and then distinguish whether it is 3D video by naked eyes. This method is time-consuming and labor-intensive.

Embodiment Construction

[0035] See figure 1 , figure 1 It is a schematic flowchart of an embodiment of a method for 3D video recognition in the present invention. Such as figure 1 As shown, this embodiment includes the process:

[0036] a. When starting up or receiving a new video input, set the default parameter to i=1,

[0037] First, after the device starts or switches to a new video, the default parameter is automatically set to i=1;

[0038] b. intercept a frame of image from the video, convert the image into a grayscale image, and split it into left and right images,

[0039] The device automatically obtains a frame of image from the video image data, converts the acquired video image into a grayscale image through a conversion algorithm, and then splits it into corresponding left and right image formats;

[0040] c. Use the corner detection algorithm to find the corners of the left and right images respectively,

[0041] In the embodiment of the present invention, the preferred corner de...

Abstract

The present invention provides a method and device for 3D video recognition, the method comprising: a. when starting up or receiving a new video input, setting the default parameter as i=1; b. intercepting a frame of image from the video, converting The image is a grayscale image, and is split into left and right images; c. use a corner detection algorithm to find the corners of the left and right images; d. use a matching algorithm to match the corners of the two images; e. The elimination algorithm eliminates wrong matching corner points; f. judge whether the logarithm of the corner points matching of two images is more than or equal to N, if so, then the video is a 3D video, if not, then execute step g; g. make the parameter i =i+1, judge whether i is greater than 3, if so, then described video is non-3D video, if not, then return to step b; Wherein, N is the matching corner logarithm of two images required during 3D video The minimum value of ; through the above method, the present invention can automatically distinguish between 3D video and non-3D video, without the need for the user to judge with the naked eye, saving the user's time and physical strength.

Description

technical field [0001] The invention relates to the field of image processing and image recognition, in particular to a method and device for 3D video recognition. Background technique [0002] The existing algorithm does not provide a method for identifying 3D video and non-3D video. People need to manually open the video to play, and then distinguish whether it is 3D video by naked eyes. This method is time-consuming and labor-intensive. [0003] In order to solve the above technical problems, the present invention provides a fully automatic method and device for distinguishing 3D video and non-3D video without relying on human eyes to distinguish carefully. Contents of the invention [0004] The present invention provides a method and device for 3D video recognition. By converting the intercepted video image and performing corner detection, corner matching and error corner elimination on the converted left and right images, a matching corner pair is finally obtained. T...
