Channel Attention in LiDAR-camera Fusion for Lane Line Segmentation

Xinyu Zhang, Zhiwei Li, Xin Gao, Dafeng Jin, Jun Li

Abstract: Highlights•A channel attention mechanism is proposed to improve LiDAR-camera fusion in lane line segmentation;•The CFECA(Cross Fusion Efficient Channel Attention) module is designed and applied to improve the fusion method and allow abundant LiDAR-camera fusion information to be used simultaneously across channels;•A method for determining fusion weights, which are transferable in multimodal fusion, is proposed.
