Conventional intra coding is retained in depth map prediction while depth modeling mode is introduced. Depth map intra coding has a heavy computational burden. Depth modeling mode can be omitted based on DC or Planar mode with the minimum sum of absolutely transform distortion. According to the relationship between angle mode and wedgelet orientation, the wedgelet direction is roughly selected. We make use of boundary gradient method to choose wedgelet pattern segmentation. The experimental results introduce that synthetic viewpoint bit rate increases by 0.62% and the encoding time decreases by 30.1% compared with HTM16.0. Compared with other algorithms, the time saving is slightly higher than other algorithms.
