ALODAD: An Anchor-Free Lightweight Object Detector for Autonomous Driving

نویسندگان

چکیده

Vision-based object detection is an essential component of autonomous driving. Because vehicles typically have limited on-board computing resources, a small-sized model required. Simultaneously, high accuracy and real-time inference speeds are required to ensure safety while In this paper, anchor-free lightweight detector for driving called ALODAD proposed. incorporates attention scheme into the neural network GhostNet builds framework achieve lower computational costs provide parameters with accuracy. Specifically, backbone integrates convolutional block that analyzes valuable features from traffic scene images generate accurate bounding box, then constructs feature pyramids multi-scale detection. The proposed method adds intersection over union (IoU) branch decoupled rank vast number candidate detections accurately. To increase data diversity, augmentation was used during training. Extensive experiments based on benchmarks demonstrate offers improved performance compared baseline. can increased meeting requirements YOLOv5 RetinaNet models 98.7% 94.5% were obtained average precision metrics AP50 AP75, respectively, BCTSDB dataset.

Driving an autonomous car with eye tracking

This paper describes eyeDriver, a hardware and software setup to drive an autonomous car with eye movement. The movement of the operator’s iris is tracked with an infrared sensitive camera built onto a HED4 interface by SMI. The position of the iris is then propagated by eyeDriver to control the steering wheel of “Spirit of Berlin”, a completely autonomous car developed by the Free University o...

Secure autonomous driving in dynamic environments: From object detection to safe driving

Secure driving in dynamic environments is an application requiring a number of premises. First of all it needs a perception system able to detect and register obstacles in the vicinity of the robot. Those obstacles are mapped and passed to a motion planner able to calculate a path considering the global objective as well as locally collision free trajectories. Finally, as the calculated path is...
