AI Technical Summary
In existing drone obstacle avoidance technologies, obstacle risk modeling is static and coarse-grained, failing to provide a refined and adaptive understanding of the environmental situation. This results in drone obstacle avoidance strategies lacking specificity and foresight, affecting the system's safety and intelligence.
A dual-modal coupled sensing method is adopted, which integrates image information and radar information. The three-dimensional centroid and geometric dimensions of obstacles are extracted through target detection and point cloud data processing. Combined with semantic risk prior coefficients and UAV status, an adaptive three-dimensional risk ellipsoid is constructed, and obstacle avoidance control commands are generated using a reinforcement learning decision network.
It enables refined and differentiated modeling of obstacle and danger zones, improves the autonomous obstacle avoidance capability and flight intelligence of UAVs in complex dynamic scenarios, and enhances the safety and generalization capability of obstacle avoidance strategies.
