Improved Neural Radiance Fields Using Pseudo-depth and Fusion

no code implementations27 Jul 2023 Jingliang Li, Qiang Zhou, Chaohui Yu, Zhengda Lu, Jun Xiao, Zhibin Wang, Fan Wang

To make the constructed volumes as close as possible to the surfaces of objects in the scene and the rendered depth more accurate, we propose to perform depth prediction and radiance field reconstruction simultaneously.

SDFReg: Learning Signed Distance Functions for Point Cloud Registration

no code implementations18 Apr 2023 Leida Zhang, Zhengda Lu, Kai Liu, Yiqun Wang

We then propose to alternately optimize the implicit function and the registration between the implicit function and point cloud.

DS-MVSNet: Unsupervised Multi-view Stereo via Depth Synthesis

no code implementations13 Aug 2022 Jingliang Li, Zhengda Lu, Yiqun Wang, Ying Wang, Jun Xiao

To mine the information in probability volume, we creatively synthesize the source depths by splattering the probability volume and depth hypotheses to source views.

DepthGAN: GAN-based Depth Generation of Indoor Scenes from Semantic Layouts

no code implementations22 Mar 2022 Yidi Li, Yiqun Wang, Zhengda Lu, Jun Xiao

Limited by the computational efficiency and accuracy, generating complex 3D scenes remains a challenging problem for existing generation networks.
