三维(3-D)跟踪和轨迹测量的群体平移和旋转的粒子可以大大有助于集体行为的研究,运动测量等的应用。双目立体方法通常用于跟踪和测量的3-D轨迹的漂移粒子。然而,双目方法通常遭受严重的立体匹配模糊面对这些情况下,即使采用运动约束来消除歧义的立体匹配。我们试图通过优化视点位置来帮助消除歧义。我们对立体匹配歧义进行建模,并在我们的几何分析基础上测试不同的视点位置,以显示对利用运动约束的消歧的影响。当目标进行组平移和旋转是高度模糊的,我们找到最佳的视点位置,使立体匹配模糊度随着时间的推移尽可能快地减少。最优视点位置可以大大提高现有方法的性能。
Three-dimensional (3-D) tracking and trajectory measurement of group translating and rotating particles may greatly help applications in collective behavior study, motion measurement, etc. Binocular stereo methods are commonly used to track and measure 3-D trajectories of drifting particles. Nevertheless, binocular methods usually suffer from severe stereo-matching ambiguity facing these situations even if motion constraint is adopted to disambiguate stereo matching. We try to help the disambiguating by optimizing viewpoint placement. We model the stereo-matching ambiguity and test different viewpoint placements upon our geometrical analysis to show the influence on the disambiguation that utilizes motion constraint. When the targets undergo group translation and rotation which are highly ambiguous, we find the optimal viewpoint placement such that stereo-matching ambiguity decreases as fast as possible over time. The optimal viewpoint placement can greatly improve the performance of existing methods.
