To assess the contributions of the different feature channels of sensors, we introduce a novel multimodal fusion method and demonstrate its practical utility using LiDAR-camera fusion networks. Specifically, a channel attention module that can be easily added to a fusion segmentation network is ...
LiDAR-Camera Fusion Image-Guided Query Initialization 结果 总结 关键词:CVPR2022, LiDAR-camera,Transformer 文章地址:arxiv 代码地址:github 文章贡献 (1)研究了激光雷达-相机融合的固有难点,并揭示了robust融合的一个关键,即软关联机制(soft-association mechanism,利用cross attention)。 (2)提出了一种新颖的tra...
由于3D点云在做camera view投影的时候丢失了原来的3D结构信息,引入了图像中的尺度变化和遮挡两个问题,因此少有方法直接在这种模式下作3D目标检测,一般需要在网络输出基础上做比较多的后处理。但是camera view的表达模式,极大的增加了远处点云的上下文信息,也是一种极好的提高点云特征表达能力的方式。 基于point-wise ...
这个投影过程也分为两步,首先在源数据上建立点云与图像像素间的对应关系,这个对应关系可以通过多传感器的标定参数计算得到:P(camera)=K*T*P(lidar),其中K为相机的内参,T为lidar到camera的标定参数,如下式,由于不同传感器获得数据是有一些时间差,通过自车的定位信息做出补偿即可。第二步则在此对应关系的基础上,将...
