代码:github.com/saic-vul/imv 摘要:将基于多视图 RGB 的 3D 物体检测任务作为端到端优化问题引入。为了解决这个问题,我们提出了 ImVoxelNet,这是一种基于单目或多视图 RGB 图像的新型全卷积 3D 物体检测方法。每个多视图输入中的单目图像数量在训练和推理过程中可能会发生变化;实际上,这个数字对于每个多视图输入...
AVOD输入RGB图像以及BEV(Bird's Eye View) Map,利用FPN网络得到二者全分辨率的feature map,然后通过crop&resize提取两个feature map对应的feature crop并融合,最后挑选出3D proposal以实现3D物体检测,整个过程是two-stage detection,可以...

centerpoint_01voxel_second_secfpn_4x8_cyclic_20e_nus.py When only the detection range changed, the model.pts_middle_encoder.sparse_shape remains the same. I am a little bit confused about when should this sparse_shape be changed. And there is no hard relationship between the voxel size and...
在基于图片的2D物体检测任务中,通常利用特征金字塔(FPN)的网络结构实现大小不同物体的proposal。YOLO V3的一个特点就是在三个不同尺度的特征图中,分别放置负责检测不同大小物体的预设框Anchor。底层的特征因为感受野小,负责小物体检测,因此放置较小的Anchor。反之,顶层的特征因感受野较大,负责大的物体的检测任务,因此...
Experiments on SemanticKITTI show that VoxFormer outperforms the state of the art with a relative improvement of 20.0% in geometry and 18.1% in semantics and reduces GPU memory during training to less than 16GB. Our code is available on https://github.com/NVlabs/VoxFormer....
