阅读说明：本技术 一种数据编码、数据解码方法、设备及存储介质 (Data encoding method, data decoding method, equipment and storage medium ) 是由 李璞 郑萧桢 陈嘉枫 王文义 虞露 于 2019-07-04 设计创作，主要内容包括：一种数据编码、数据解码方法、设备及存储介质,其中,该方法包括：确定点云数据的语法元素的取值；当根据语法元素的取值确定搜索范围不为0时,对点云的属性值进行预测处理,得到点云的属性值的残差；对点云的属性值的残差进行编码得到第一码流数据,其中,所述第一码流数据中包括标识信息,所述标识信息用于指示至少一个点云点的属性值的残差为0(S902)；当根据语法元素的取值确定搜索范围为0时,跳过“对点云的属性值进行预测处理”的步骤,对点云的属性值进行编码得到第二码流数据,其中,所述第二码流数据中不包括第一标识(S903)。通过这种方式可以降低编码、解码的算法复杂度,提高编码、解码的效率。(A data encoding method, a data decoding method, equipment and a storage medium, wherein the method comprises the following steps: determining the value of a syntactic element of the point cloud data; when the search range is determined to be not 0 according to the value of the syntactic element, performing prediction processing on the attribute value of the point cloud to obtain a residual error of the attribute value of the point cloud; coding a residual error of an attribute value of a point cloud to obtain first code stream data, wherein the first code stream data comprises identification information, and the identification information is used for indicating that the residual error of the attribute value of at least one point cloud point is 0 (S902); when the search range is determined to be 0 according to the value of the syntax element, the step of 'performing prediction processing on the attribute value of the point cloud' is skipped, and the attribute value of the point cloud is encoded to obtain second code stream data, wherein the second code stream data does not include the first identifier (S903). By the method, the complexity of the coding and decoding algorithm can be reduced, and the coding and decoding efficiency can be improved.)
