Cooperative perception offers several benefits for enhancing the capabilities of autonomous vehicles and improving road safety. Using roadside sensors in addition to onboard sensors increases reliability and extends the sensor range. External sensors offer higher situational awareness for automated vehicles and prevent occlusions. We propose CoopDet3D a cooperative multi-modal fusion model and TUMTraf-V2X a perception dataset for the cooperative 3D object detection and tracking task. Our dataset contains 2000 labeled point clouds and 5000 labeled images from five roadside and four onboard sensors. It includes 30k 3D boxes with track IDs and precise GPS and IMU data. We labeled nine categories and covered occlusion scenarios with challenging driving maneuvers like traffic violations near-miss events overtaking and U-turns. Through multiple experiments we show that our CoopDet3D camera-LiDAR fusion model achieves an increase of +14.36 3D mAP compared to a vehicle camera-LiDAR fusion model. Finally we make our dataset model labeling tool and devkit publicly available on our website: https://tum-traffic-dataset.github.io/tumtraf-v2x.
