基于单目视觉的前方车辆检测与测距方法研究

提出了一种基于单目视觉的前方车辆检测与测距方法.首先利用自适应闻值分割方法得到车辆底部阴影特征,同时采用区域融合方法解决车辆边缘变形问题,得到疑似车辆区域,然后在疑似区域内利用车辆对称性进行验证,得到准确车辆区域,最后利用基于摄像机内部参数和几何关系的单目视觉测距方法得到本车与前方车辆之间的距离.实验结果表明,该方法能...

Study on Method of Preceding Vehicles Detection and Distance Measurement Based on Monocular Vision

To meet the requirement of vehicle safety,a method is presented which can be used to detect the preceding vehicles and get the distance between own car and the car ahead.Firstly,an adaptive threshold method is used to get shadow feature,and a shadow area merge approach is used to resolve the distortion of the shadows border.Then,symmetry feature is analyzed to verify whether there exist vehicles in the interesting areas and to locate the vehicles.Finally,using monocular vision distance measurement based on ...
