Embodiment

[0031] like figure 1 As shown, the binocular stereo video coding method in this example is completed by the following steps:

[0032] a0. Perform color correction on the left and right viewpoint images, so that the brightness information of the left and right viewpoint images to be encoded is basically consistent, and eliminate the error caused by the inconsistency of the brightness of the left and right viewpoint image acquisition; at the same time, initialize the initialization quantization parameters of the video signal and set the threshold for scene switching and the maximum number of B frames allowed to be inserted, and set the maximum number of reference frames and the maximum interval of I frames.

[0033] a. Read the left view video image to the buffer frame by frame and perform scene detection and analysis. If a scene switch occurs or the current frame is the first frame to be encoded, set the encoding type of the current frame to I frame and start from this position...

Abstract

The invention relates to a video coding technique and discloses a method for coding a binocular stereo video for solving problems of no flexibility, poor image quality and poor video reconstruction stability in the traditional technology. The technical scheme has the key points as follows: the method for coding the binocular stereo video comprises the following steps of: detecting scene switch by reading a left viewpoint sequence image frame by frame, and analyzing relativity and complexity of a left viewpoint time domain at the same time; and judging the coding type of a left viewpoint image to be coded, regulating an image coding sequence and determining a reference frame selection. After a left viewpoint image coding structure is determined, the coding type of a right viewpoint image is determined and left-right viewpoint images are respectively coded according to a right viewpoint time domain and the relativity of the left-right viewpoints. The invention is suitable for coding the binocular stereo video.

Description

technical field [0001] The invention relates to video coding technology, in particular to a binocular stereoscopic video coding method. Background technique [0002] In the field of video display technology, the main development trend is to pursue more real and clear features of natural scenes. After decades of development and application, analog TV will be gradually replaced by digital TV. High-definition digital TV (HDTV) further improves the visual reality by increasing the resolution of image display. The limitations of current 2D video in representing the depth information of natural scenes have made it unable to meet people's needs for true and natural reproduction of scenes. [0003] When the two eyes observe an object, there is a slight difference in the imaging position of the object on the retina of the two eyes, which is called binocular parallax. Binocular parallax is fused through the visual cortex of the brain to enhance people's three-dimensional perception ...
