Embodiment

[0086] The detailed process of the 3D pattern recognition method based on color and shape matching in this example is as follows:

[0087] 1. Grab a frame of video image and zoom.

[0088] In order to avoid the black screen process at the beginning of the video, this example chooses to grab the video when the video has been played for 2 seconds.

[0089] Then the target image is reduced to 256X240. After testing, the ARM9 processor with a clock frequency of 700MHz can process an image of this size at a speed of about 200ms, and the user will not feel a pause.

[0090] 2. Match in the left and right mode.

[0091] 2.1. Divide the captured image into two parts according to the left and right mode, namely the left eye image and the right eye image.

[0092] 2.2. Remove the upper and lower black borders;

[0093] If the brightness of the first and last rows of the target image is too low (below 20), it means that the video has upper and lower black borders. In the current video interface, the...

Abstract

The invention relates to the 3D television technology and especially relates to a 3D mode identification method. In the prior art, the 3D mode does not possess an automatic identification function. The invention discloses the 3D mode identification method based on image processing, especially based on color and shape matching. The 3D mode identification method based on the color and shape matching is characterized by: dividing a video image into left and right eye images; then setting one image to be the image of the 3D mode; carrying out the color matching and the shape matching of the left and right eye images by using a mature color matching algorithm and a mature shape matching algorithm in an image processing technology; determining that the 3D mode of the video image is the set 3D mode when the color and the shape reach a matching condition, otherwise determining that the video image is not the 3D mode video image. By using the invention, 3D video mode identification accuracy ishigh; an identification algorithm is simple and high efficient. The method can be used in video equipment, such as a television and the like, so that automatic identification and mode switching can be performed.

Description

Technical field [0001] The present invention relates to 3D television technology, in particular to a 3D pattern recognition method. Background technique [0002] 3D TV is a three-dimensional TV technology that uses the visual characteristics of the human eye. The 3D video image includes the left-eye image and the right-eye image. The 3D television technology display terminal displays the left-eye image and the right-eye image in a certain way, and generates a stereoscopic image effect through human eye synthesis. [0003] With the development of 3D TV technology, users' requirements for TV 3D functions are gradually increasing. TV manufacturers need to design more friendly 3D interaction methods, but compared with 2D TVs, 3D TV interaction methods still have many inconveniences, such as : [0004] 1. At present, most of the 3D videos require users to adjust the 3D video mode of the TV, such as: top and button, side by side, line by line, etc., especially in the right When selectin...
