The development of aerial autonomy has enabled aerial robots to fly agilely in complex environments. However, dodging fast-moving objects in flight remains a challenge, limiting the further application of unmanned aerial vehicles(UAVs). The bottleneck of solving this problem is the accurate perception of rapid dynamic objects. Recently, event cameras have shown great potential in solving this problem. This paper presents a complete perception system including ego-motion compensation, object detection, and trajectory prediction for fast-moving dynamic objects with low latency and high precision. Firstly, we propose an accurate ego-motion compensation algorithm by considering both rotational and translational motion for more robust object detection. Then, for dynamic object detection, an event camera-based efficient regression algorithm is designed. Finally, we propose an optimization-based approach that asynchronously fuses event and depth cameras for trajectory prediction. Extensive real-world experiments and benchmarks are performed to validate our framework. Moreover, our code will be released to benefit related researches.

The video presents the paper Canfly: A Can-sized Autonomous Mini Coaxial Helicopter.
The development of autonomous rotary-wing UAVs has shown an evident tendency in miniaturization. However, the side effects brought by miniaturization, such as decreased load capability, shorter flight duration, and reduced autonomous ability, seriously hinder the process. In this paper, we firstly investigate into the configuration of different rotary-wing aircraft and optimize the configuration selection. Afterward, with several elaborate mechanisms contributing for the miniaturization, we present the hardware design and control strategy of a mini coaxial helicopter, which is 62% smaller than the smallest autonomous quadrotor so far [1] in the collision area. Abundant experiments reveal that it achieves impressive traversability and is capable of carrying autonomous tasks in unknown dense scenarios, while maintaining satisfactory performance regarding loadability and flight duration.
