[0025] By studying the inter-view texture correlation, the sub-block division method corresponding to the largest coding unit of the independent view to be encoded can be determined by using the division level information of the largest coding unit in the independent view. Because the baselines between adjacent viewpoints are short and the content in adjacent viewpoints is the same, the divisions in different viewpoints have great similarity, so the sub-blocks in the largest coding unit in non-independent viewpoints can be preliminarily obtained. At the same time, the quadtree conditional constraints correct the initially obtained division, so that it can be directly used to guide the division of the largest coding unit of the dependent view without complicated calculations, and the load introduced by the entire encoder is negligible. On the premise of ensuring the encoding quality, the complexity of the encoding process operation can be greatly reduced.
