THREE-DIMENSIONAL IMAGE CODING METHOD, THREE-DIMENSIONAL IMAGE DECODING METHOD AND RELATED DEVICE

摘要

Embodiments of the present invention disclose a three-dimensional image encoding method, a three-dimensional image decoding method, and a related apparatus. A three-dimensional video decoding method may include: decoding a video bitstream to obtain a single sample flag bit corresponding to a current image block in a current depth map; performing detection on a first adjacent prediction sampling point and a second adjacent prediction sampling point of the current image block in the current depth map if the single sample flag bit obtained by decoding indicates that a decoding mode corresponding to the current image block is a single depth intra-frame mode; and constructing a sample candidate list according to results of the detection on the first adjacent prediction sampling point and the second adjacent prediction sampling point, where the sample candidate list includes a first index location and a second index location; decoding the video bitstream to obtain a single sample index flag bit corresponding to the current image block. Solutions in the embodiments of the present invention help to reduce complexity of an SDM-based encoding and decoding algorithm and decrease a storage space occupation requirement.
