Are All Point Clouds Suitable for Completion? Weakly Supervised Quality Evaluation Network for Point Cloud Completion

no code implementations3 Mar 2023 Jieqi Shi, Peiliang Li, Xiaozhi Chen, Shaojie Shen

In this paper, we propose a quality evaluation network to score the point clouds and help judge the quality of the point cloud before applying the completion model.

You Only Label Once: 3D Box Adaptation from Point Cloud to Image via Semi-Supervised Learning

no code implementations17 Nov 2022 Jieqi Shi, Peiliang Li, Xiaozhi Chen, Shaojie Shen

The image-based 3D object detection task expects that the predicted 3D bounding box has a ``tightness'' projection (also referred to as cuboid), which fits the object contour well on the image while still keeping the geometric attribute on the 3D space, e. g., physical dimension, pairwise orthogonal, etc.

Temporal Point Cloud Completion with Pose Disturbance

no code implementations7 Feb 2022 Jieqi Shi, Lingyun Xu, Peiliang Li, Xiaozhi Chen, Shaojie Shen

With the help of gated recovery units(GRU) and attention mechanisms as temporal units, we propose a point cloud completion framework that accepts a sequence of unaligned and sparse inputs, and outputs consistent and aligned point clouds.

Graph-Guided Deformation for Point Cloud Completion

no code implementations11 Nov 2021 Jieqi Shi, Lingyun Xu, Liang Heng, Shaojie Shen

In this paper, we propose a Graph-Guided Deformation Network, which respectively regards the input data and intermediate generation as controlling and supporting points, and models the optimization guided by a graph convolutional network(GCN) for the point cloud completion task.

Tracking from Patterns: Learning Corresponding Patterns in Point Clouds for 3D Object Tracking

no code implementations20 Oct 2020 Jieqi Shi, Peiliang Li, Shaojie Shen

A robust 3D object tracker which continuously tracks surrounding objects and estimates their trajectories is key for self-driving vehicles.

Joint Spatial-Temporal Optimization for Stereo 3D Object Tracking

no code implementations CVPR 2020 Peiliang Li, Jieqi Shi, Shaojie Shen

Directly learning multiple 3D objects motion from sequential images is difficult, while the geometric bundle adjustment lacks the ability to localize the invisible object centroid.
