Abstract

We present a new deep point cloud rendering pipeline through multi-plane projections. The input to the network is the raw point cloud of a scene and the output are image or image sequences from a novel view or along a novel camera trajectory. Unlike previous approaches that directly project features from 3D points onto 2D image domain, we propose to project these features into a layered volume of camera frustum. In this way, the visibility of 3D points can be automatically learnt by the network, such that ghosting effects due to false visibility check as well as occlusions caused by noise interferences are both avoided successfully. Next, the 3D feature volume is fed into a 3D CNN to produce multiple planes of images w.r.t. the space division in the depth directions. The multi-plane images are then blended based on learned weights to produce the final rendering results. Experiments show that our network produces more stable renderings compared to previous methods, especially near the object boundaries. Moreover, our pipeline is robust to noisy and relatively sparse point cloud for a variety of challenging scenes.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • The warped images usually contain isolated pixels, and the foreground and background are entangled, which jeopardizes video quality.

    “In addition, the warped images usually contain isolated pixels, and the foreground and background are entangled, which jeopardizes video quality [5].”

    From SVG: 3D Stereoscopic Video Generation via Denoising Frame Matrix (2024) · cites this paper as [5]

    Section 4.4 reports that 2D-projection methods can produce a mixture of foreground and background under noisy depth, and that changing projections can cause jittering artifacts in videos. The Figure 2 caption describes holes in re-projected point-cloud images, but our copy does not say that warped images usually contain isolated pixels. The claim also generalizes these problems beyond the conditions the paper discusses. (LLM, conf=0.84)

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
