| 英文摘要 |
| This paper proposes a novel method for 3D probabilistic discrete bi-level programming (3D-PDBP) to address
the limitations of current discrete target search methods in dynamic 3D environments. The proposed method enables
the search for low-maneuverability targets with uncertain positions, particularly suited for scenarios where the target’s
state changes intermittently in the short term. To dynamically update the distribution probability of the target, the paper
introduces a probabilistic dynamic update model HMF-PU that can mimic human memory and a forgetting mechanism
is built based on the Ebbinghaus forgetting curve. By combining the target’s prior semantic information with distribution
probability, the paper constructs a probabilistic semantic map for effective target search. The proposed 3D-PDBP combines
observation point search sequence planning with depth vision sensor motion planning, planning the observation point search
sequence based on the probabilistic semantic map and orchestrating the servo process of the visual sensor using the target’s
probability distribution model HMF-PU. Experimental results reveal that 3D-PDBP can accomplish target search tasks
efficiently in unpredictable situations, and HMF-PU can successfully balance the importance and real-time performance of
target information. |
