Lightweight Fisheye Object Detection Network with Transformer-based Feature Enhancement for Autonomous Driving

Hu Cao, Yanpeng Li, Yinlong Liu, Xinyi Li, Guang Chen, Alois Knoll

IROS 2024poster

Fisheye cameras, offering a wide field of view (FOV) of 360◦, are extensively employed for surround-view perception in autonomous driving. Compared with the object detection on the standard images, it lacks studies for fisheye images. Moreover, efficient perception is crucial for autonomous vehicles…
