本文讨论了使用多摄像机进行道路交通监控的问题。目的是消除经典的单眼模糊性并检索物体的高度。介绍了一种高效、简单的校准方法。它具有与道路几何形状限制相关的特殊性。该方法依赖于射影几何并使用无穷远平面的结构。在第二阶段，引入高速匹配过程。它基于道路场景的高度平面分解。由于高度采样，该方法自然实现了两个任务。匹配和重建变得同时进行。最后给出了实验结果。
This paper deals with the issue of using multi-cameras for road traffic monitoring. The aim is to remove the classic monocular ambiguities and to retrieve the objects' height. An efficient and simple calibration method is introduced. It has the particularity to be connected to the geometry constraints of the road. The method relies on projective geometry and uses the structure of the plane at infinity. In a second stage, a high speed matching procedure is introduced. It is based on an altitude planar decomposition of the road scene. The method naturally achieves two tasks due to altitudes sampling. Match and reconstruction become simultaneous. Finally, experimental results are presented.
