摘　　要：自动获取公交车在停靠车站的上下车乘客数目对于合理、有效地调度车辆运行具有重要意义。利用图像处理技术对运动乘客进行跟踪统计时,由于目标的形状是随机变化的,甚至总是部分出现在视野范围之内,所以不能采用基于形状和特征点的跟踪方法。本文提出了一种基于差分图像和区域生长的,对多个形变目标运动区域特征进行跟踪的方法。实验表明此方法能够实时地、较准确地统计出上下车的乘客数目。It is very important to count passengers who get on and get off for scheduling bus effectively. The methods based on target shape and feature points can not be adopted to track and count the moving passengers, because the target shapes keep changing from time to time randomly and even appear partially in field of vision captured. Based on differential image and region growing, a new method is proposed in this paper for tracking the moving regions of multiple targets whose shapes are variable. The result of experiment shows that the method is able to count objects with preferable accuracy in real-time application.
