移动物体的主动三维重建需在决策到执行的延迟期内,选择具有信息量的观测视角并考虑物体运动不确定性。现有方法仅解决部分问题:传统下一最佳视角(NBV)规划优化表面覆盖但假设物体静止;面向运动目标的主动感知虽考虑运动,但侧重跟踪或可见性而非重建覆盖率。本文提出一种考虑运动不确定性的NBV框架,用于重建平面运动的未知刚体物体,基于移动机器人获取的物体噪声平面位置测量与深度观测。核心思想是评估每个候选视角在由运动与测量不确定性引发的多种未来物体状态下的预期观测质量,而非单一预测姿态。通过固定滞后高斯过程平滑器从噪声位置数据中估计并预测物体状态,生成围绕预测位置的候选视角,经可达性过滤后,计算其期望覆盖率得分。仿真与实测结果表明,该方法在重建完整性上优于非预测型NBV和仅预测追踪的方法,有效融合了覆盖驱动的主动重建与预测驱动的追踪。

原文摘要 · Abstract (English)

Active 3D reconstruction of moving objects requires selecting informative viewpoints while accounting for object motion uncertainty during the decision-to-execution delay. Existing methods address only parts of this problem: next-best-view (NBV) planners for object reconstruction typically optimize surface coverage but assume static objects, while motion-aware active perception for moving targets accounts for target motion but prioritizes tracking or visibility over reconstruction coverage. This work presents a motion-uncertainty-aware NBV framework for reconstructing an unknown rigid object undergoing planar motion, using noisy planar position measurements of the object and depth observations from a mobile robot. The key idea is to evaluate each candidate viewpoint by its expected observation quality over plausible future object states induced by motion and measurement uncertainty, rather than at a single predicted object pose. To obtain this predictive belief, a fixed-lag Gaussian Process smoother estimates and predicts the object state from noisy position measurements. The resulting belief is used to generate candidate viewpoints around the predicted object location, filter them by reachability, and estimate their expected coverage-driven scores. Simulation and real-world experiments demonstrate improved reconstruction completeness over non-predictive NBV and prediction-only tracking methods, bridging coverage-driven active reconstruction and prediction-driven tracking.
