摘要:

对于低成本的城市自动驾驶和移动机器人来说,使用单个RGB相机估计环境中物体的3D位置和方向是一项关键且具有挑战性的任务。现有的大多数算法都是基于二维-三维对应关系中的几何约束,这源于通用的6D对象位姿估计。我们首先确定地平面如何在驾驶场景中的3D检测中为深度推理提供额外的线索。基于这一观察,我们然后改进了3D锚点的处理,并引入了一种新的神经网络模块,以充分利用深度学习框架中的特定于应用的先验知识。最后,我们介绍了一个高效的神经网络嵌入所提出的模块的三维目标检测。我们进一步验证了所提出的模块与神经网络设计的单目深度预测的权力。这两个网络分别在KITTI 3D目标检测和深度预测基准上实现了最先进的性能。该代码将在https://www.github.com/Owen-Liuyuxuan/visualDet3D上发布

英文摘要:

Estimating the 3D position and orientation of objects in the environment with a single RGB camera is a critical and challenging task for low-cost urban autonomous driving and mobile robots. Most of the existing algorithms are based on the geometric constraints in 2D-3D correspondence, which stems from generic 6D object pose estimation. We first identify how the ground plane provides additional clues in depth reasoning in 3D detection in driving scenes. Based on this observation, we then improve the processing of 3D anchors and introduce a novel neural network module to fully utilize such application-specific priors in the framework of deep learning. Finally, we introduce an efficient neural network embedded with the proposed module for 3D object detection. We further verify the power of the proposed module with a neural network designed for monocular depth prediction. The two proposed networks achieve state-of-the-art performances on the KITTI 3D object detection and depth prediction benchmarks, respectively. The code will be published in https://www.github.com/Owen-Liuyuxuan/visualDet3D
