In this paper, a new compact vision sensor consisting of two fisheye event cameras mounted back to back is presented, offering a full 360-degree view of the surrounding environment. The optical design, projection model, and practical calibration using incoming event streams of the novel stereo camera called SFERA are described. Its potential for real-time target tracking is evaluated using a Bayesian estimator adapted to the sphere’s geometry. Real-world experiments with a prototype including two synchronized Prophesee EVK4 cameras and a DJI Mavic Air 2 quadrotor demonstrate the system’s effectiveness for aerial surveillance.

In this paper, the Asynchronous Event Multi-Object Tracking (AEMOT) algorithm is presented for detecting and tracking multiple objects by processing individual raw events asynchronously. AEMOT detects salient event blob features by identifying regions of consistent optical flow using a novel Field of Active Flow Directions built from the Surface of Active Events. Detected features are tracked as candidate objects using the recently proposed Asynchronous Event Blob (AEB) tracker to construct small intensity patches of each candidate object.

The Florence RGB-Event Drone dataset (FRED) is a novel multimodal dataset specifically designed for drone detection, tracking, and trajectory forecasting, combining RGB video and event streams. FRED features more than 7 hours of densely annotated drone trajectories, using five different drone models and including challenging scenarios such as rain and adverse lighting conditions.

This paper proposes a neural network framework for predicting the time and collision position of an unmanned aerial vehicle with a dynamic object, using RGB and event-based vision sensors. The proposed architecture consists of two separate encoder branches, one for each modality, followed by fusion by self-attention to improve prediction accuracy. To facilitate benchmarking, the ABCD dataset is leveraged, enabling detailed comparisons of single-modality and fusion-based approaches.

This article presents NeuroBench, a benchmark framework for neuromorphic algorithms and systems. It introduces a common set of tools and systematic methodology for inclusive benchmark measurement, delivering an objective reference framework for quantifying neuromorphic approaches in both hardware-independent and hardware-dependent settings.

This paper presents the first recording of a total solar eclipse with a pair of high-resolution event cameras, with accompanying methodology. A method is proposed to stabilize the recordings to counteract manual tripod adjustments required to track celestial bodies in-frame. A high-dynamic range image of the sun is also generated during the eclipse, showing how event cameras excel in this aspect compared to traditional CMOS-based cameras.
