摘　　要：为有效获取交叉口行人信息,提高过街行人安全性,提出了基于图像技术和人行横道线特征的交叉口过街行人交通参数获取方法。利用横道线特征建立了行人识别感兴趣区和人行横道线的曲线方程,以识别行人和确定行人在交叉口的位置、行进速度。试验结果表明,该方法可以有效地确定出过街行人交通参数。In order to improve the safety of pedestrian when walking through intersection,a method for acquiring the parameter of pedestrian traffic based on an image analysis technique is presented.In this method,the area of interest where the zebra strips present and the equations for describing their presence are developed and the position and speed of pedestrian are then captured and extracted according to the identified zebra stripes feature.The results show that the proposed method can provide a new way to extract the pedestrian traffic and provide additional data for an improved intersection control.
