PillarNeSt: Embracing Backbone Scaling and Pretraining for Pillar-based 3D Object Detection

no code implementations29 Nov 2023 Weixin Mao, Tiancai Wang, Diankun Zhang, Junjie Yan, Osamu Yoshie

Pillar-based methods mainly employ randomly initialized 2D convolution neural network (ConvNet) for feature extraction and fail to enjoy the benefits from the backbone scaling and pretraining in the image domain.

ADriver-I: A General World Model for Autonomous Driving

no code implementations22 Nov 2023 Fan Jia, Weixin Mao, Yingfei Liu, Yucheng Zhao, Yuqing Wen, Chi Zhang, Xiangyu Zhang, Tiancai Wang

Based on the vision-action pairs, we construct a general world model based on MLLM and diffusion model for autonomous driving, termed ADriver-I.

GMM: Delving into Gradient Aware and Model Perceive Depth Mining for Monocular 3D Detection

no code implementations30 Jun 2023 Weixin Mao, Jinrong Yang, Zheng Ge, Lin Song, HongYu Zhou, Tiezheng Mao, Zeming Li, Osamu Yoshie

In light of the success of sample mining techniques in 2D object detection, we propose a simple yet effective mining strategy for improving depth perception in 3D object detection.

Exploring Recurrent Long-term Temporal Fusion for Multi-view 3D Perception

no code implementations10 Mar 2023 Chunrui Han, Jinrong Yang, Jianjian Sun, Zheng Ge, Runpei Dong, HongYu Zhou, Weixin Mao, Yuang Peng, Xiangyu Zhang

In this paper, we explore an embarrassingly simple long-term recurrent fusion strategy built upon the LSS-based methods and find it already able to enjoy the merits from both sides, i. e., rich long-term information and efficient fusion pipeline.

Towards 3D Object Detection with 2D Supervision

no code implementations15 Nov 2022 Jinrong Yang, Tiancai Wang, Zheng Ge, Weixin Mao, Xiaoping Li, Xiangyu Zhang

We propose a temporal 2D transformation to bridge the 3D predictions with temporal 2D labels.

PersDet: Monocular 3D Detection in Perspective Bird's-Eye-View

no code implementations19 Aug 2022 HongYu Zhou, Zheng Ge, Weixin Mao, Zeming Li

To address this problem, we revisit the generation of BEV representation and propose detecting objects in perspective BEV -- a new BEV representation that does not require feature sampling.

DBQ-SSD: Dynamic Ball Query for Efficient 3D Object Detection

1 code implementation22 Jul 2022 Jinrong Yang, Lin Song, Songtao Liu, Weixin Mao, Zeming Li, Xiaoping Li, Hongbin Sun, Jian Sun, Nanning Zheng

Many point-based 3D detectors adopt point-feature sampling strategies to drop some points for efficient inference.

Dense Teacher: Dense Pseudo-Labels for Semi-supervised Object Detection

2 code implementations6 Jul 2022 HongYu Zhou, Zheng Ge, Songtao Liu, Weixin Mao, Zeming Li, Haiyan Yu, Jian Sun

To date, the most powerful semi-supervised object detectors (SS-OD) are based on pseudo-boxes, which need a sequence of post-processing with fine-tuned hyper-parameters.
