特征级监督的毫米波雷达和视觉融合的目标检测
Feature Level Supervised Millimeter Wave Radar and Vision Fusion for Target Detection
摘要
Abstract
To address the issue of lacking effective supervision in the feature fusion stage of millimeter-wave(MMW)radar and vision sensor fusion algorithms,a multimodal fusion-based 3D object detection algorithm called LRCFusion(Radar and Camera Fusion Based on LiDAR Supervision)is proposed.The algorithm first extracts data features separately from the vision sensor,LiDAR,and MMW radar.Then,with the method of knowledge distillation,it uses LiDAR features as the teacher model to supervise MMW radar features,in order to improve the expression level of millimeter wave radar features.Subsequently,an attention mechanism is introduced to fuse the MMW radar and vision features,and a point cloud-based 3D object detection method is employed to detect objects and predict 3D anchor boxes based on the fused features.Finally,the predicted 3D anchor boxes are used to update the 3D reference points before fusion.Compared with baseline algorithms,the LRCFusion algorithm achieves a 1.2%increase in average precision and a 1%improvement in normalized detection score.关键词
