Point Sequence分支:[-2,2]5帧点拼接.做前景分割,输出256维信息,Box Sequence分支:可以用1D ConvNet或者全连接网络或者一个图神经网络.将每个box看成一个点,有7维属性.实验发现,用PointNet简单且有效.最终得到128维的特征向量.concat特征,再用一个Box回归网络,预测当前帧的box.实验:如何选择关键帧(key frame):...
第一个module就是前景背景分割的网络,这个和之前的类似,但是要注意这个时候的输入是把点云转到中间frame的det-box坐标系下去. 第二个module,是输入点云和box-sequence, 然后分别去提feature, 再进行concat,最终经过一个回归网络. 整个过程如下 输入sequence points,由世界坐标系下转到中间frame的det-box坐标系下. 经...
Our experimental evaluation confirms that recurrent processing of point cloud sequences results in significantly better SSFE compared to using only two frames. Additionally, we demonstrate that this approach can be effectively modified for sequential point cloud forecasting (SPF), a related problem that...

Object tracking on point cloud data sequence. Detect, classify, and track vehicles by using sequential lidar data captured by a lidar sensor mounted on an ego vehicle. Semantic segmentation of point clouds using SqueezeSegV2. Organized lidar data is semantically segmented into car (red), truck (...
Effective learning of spatial-temporal information within a point cloud sequence is highly important for many down-stream tasks such as 4D semantic segmentation and 3D action recognition. In this paper, we propose a novel framework named Point Spatial-Temporal Transformer (PST2) to learn spatial-tem...
Display sequence of PLY files. Add PCV instance, load first file of sequence. Then use Sequence panel to load the rest of sequence. Points from files can be preloaded to memory for smooth playback, or loaded on fly. Preloaded sequence displays only current frame that need to fit in gpu...
