A LiDAR-Based Parking Slots Detection System

To improve the robustness and effectiveness for detecting free parking spaces, we propose a LiDAR-based parking sensing system, which contains multi-modules, i.e., perception, free space parking lots’ construction, parking space tracking and obstacle detection. Comprehensive experiments demonstrate that our LiDAR-based parking sensing system can not only predict free parking spaces at a long distance, but also can achieve superior performance in terms of recall rate and accuracy of detected parking spaces. Moreover, our proposed LiDAR-based parking sensing system can achieve a significant gain over the ultrasonic-based one. Therefore, our proposed system can act an effective solution for detecting free parking slots at a long distance in the field of autonomous driving.
