首先将雷达输入的3D点云投影到俯视图和鸟瞰图,接着用鸟瞰图通过卷积网络以及3D bounding-box回归之后生成低精度的3D proposal,然后将此3D proposal投影到俯视图,鸟瞰图和单目图像,通过一个融合网络,最后将其通过多任务损失函数进行训练。 在这篇文章MLOD: A multi-view 3D object detection based on robust feature ...
3D object detectionAutonomous drivingFor the camera-LiDAR-based three-dimensional (3D) object detection , image features have rich texture descriptions and LiDAR features possess objects' 3D information. To fully fuse view-specific feature maps, this paper aims to explore the two-directional fusion ...
利用Voxel queries,通过由粗到精的方式学习场景的3D occupancy表示,联合训练检测和分割任务,利用空间稀疏性在3D 体素空间上进行操作(不是BEV空间)。核心网络设计是Occupancy Encoder和Decoder。 Abstract 当前的3D感知任务一般是针对某些特定的方面,这种分治的思想无法建立端到端的3D环境整体感知的统一表示。为了解决这个限...
为了计算query和key之间的相似度,query和key应该在相同的空间内,而key是在2D 图像空间内, query在3D空间内,因此需要将query投影到不同的camera上进行相似度计算。 第一个式子是先由query转成预测的3D box,然后拿到3D box的中心点,第二个式子是通过外参矩阵,由该中心点映射到对应camera上,第三个式子相当于对对应...
Several works have recently been proposed for 3D object detection or map segmentation from RGB images. Inspired by DETR [62] in 2D detection, DETR3D [63] links learnable 3D object queries with 2D images by camera projection matrices and enables end-to-end 3D bounding box prediction without ...
The overall completion rate was 77.4%, the detection rate was 64.5%, and there was no capsule retention. All capsule endoscopic procedures were completed uneventfully. In conclusion, newly developed 3D capsule endoscopy was safe and feasible, showing similar performance as conventional capsule endoscopy...

Comprehensive modeling of the surrounding 3D world is key to the success of autonomous driving. However, existing perception tasks like object detection, road structure segmentation, depth & elevation estimation, and open-set object localization each only focus on a small facet of the holistic 3D sc...
This paper presents a robust real-time rear-view camera based object detection algorithm for backup aid and parking assist applications. The system is capable of handling the challenges of stationary as well as moving objects in rear view of the host vehicle, utilizing a single car-mounted rear...
