Detect and localize drones in diverse environments with CVEDIA's ICARUS Counter UAS Detector model, a deep learning based drone detection model performing from a ground-to-aerial perspective. Trained with synthetic data using a wide collection of photorealistic 3D models and environments, the model was trained to distinguish drones from other moving objects for a lower false positive rate. ICARUS was trained in various environmental conditions, as well as challenging scenarios including distant and small objects, multiple targets, and sensor degradation.
