A UAV object detection and spatial mapping framework integrating enhanced YOLOv7 with graph attention networks

This study proposes a unified UAV perception framework that combines enhanced YOLOv7-based small-object detection with graph attention reasoning and spatial projection. The framework augments conventional single-stage detection with relation-aware context modeling while preserving real-time throughput at an input resol...
