摘要
通过对图像中的斑块进行分析,获得斑块在图像中的信息,由非线性校正算法将其恢复为实际道路中信息。依据一定的条件将斑块聚合为车辆以提取车辆信息,进而判断是否有车辆队列,得到较为准确的车流长度。实验结果表明,该检测算法有较高的准确性,且能满足监控的实时性。
We can acquire the blob＇s true information by blob analysis algorithm and rectifying algorithm for nonlinear distortion, then get the vehicle＇s information by blob grouping algorithm. Based on this information, the length of tragic queue can be detected. It can be seen from the experimental results that this algorithm has high accuracy and its disposal speed is sufficient for real time.
