基于轮廓特征的车辆遮挡检测和分离算法

在交通场景下进行多目标跟踪时,如何正确检测出车辆间的相互遮挡是影响车辆跟踪结果的影理论分析交通场景的三维几何投影特征.用长方体投影轮廓模型对车辆进行建模,重构其三维投影轮廓,以进行遮挡的检测和分离.与以往的方法相比,它在估计出的车辆外形轮廓基础上进行遮挡检测,不需要匹配操作,计算量较小,并能解决基于匹配的方法无法对付的初始遮挡问题.用实验验证了该算法的有效性.

A Vehicle Contour-based Method for Occlusion Detection and Segmentation

In multi-object tracking of traffic scene,how to detect the occlusion is a key problem for vehicle tracking.A novel vehicle contour based method is proposed to deal with this problem.This method firstly extracts the 3D geometry character from the vehicle images according to the projecting theory,establishes the model of the vehicle with the cuboid project contour,and then reconstructs its 3D project contour,detects and segments the occlusion regions.Compared with traditional method,it deals with the problem...
