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 ...
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...
具体实现为:使用每个选定候选对象的类别(例如,属于第 k 个类别的\hat{S}_{i j k}),我们将query特征与通过将one-hot category 线性投影到\mathbb{R}^{d}的向量而产生的category embedding进行element-wise sum。 LiDAR-Camera Fusion Image Feature Fetching(图像特征提取)当一个对象只包含少量的激光雷达点时,p...

17 briefly reviewed the methods of fusion and enhancement for LiDAR and camera sensors in the fields of depth completion, semantic segmentation, object detection, and object tracking. Xu et al.18 proposed a novel two-stage approach named FusionRCNN. It fused sparse geometry information from LiDAR...
