ABSTRACT This work proposes a simple yet efficient way to estimate pedestrians flow direction based on videos from still cameras. It does that by localizing the extremities of head and feet of silhouettes and fitting them to lines. As the previous in three-dimensional space of these lines are parallel, their intersection point is the vanishing point. Using the computed vanishing point and two internal camera parameters, the horizontal direction of moving pedestrian is determined. Our method competes for the state-of-the-art methods and achieves a high rate accuracy for direction classification.

快速准确的移动行人方向估计

摘要这项工作提出了一种简单而有效的方法来基于静态摄像机的视频估计行人流向。它通过定位轮廓的头部和脚部的末端并将它们拟合到线条来做到这一点。由于这些线在三维空间中的前一条线是平行的，它们的交点就是灭点。使用计算出的消失点和两个内部相机参数，确定移动行人的水平方向。我们的方法与最先进的方法竞争，并实现了方向分类的高准确率。
