摘要
在绊线检测中,高斯模型用于背景建模,背景差分用于前景目标提取,扫描虚拟线上所有点,当检测到目标穿越绊线后,若为双向绊线,系统直接报警;若为单向绊线,利用目标颜色直方图欧拉距离来确定目标运动方向,如果目标运动方向与禁止穿越方向一致,系统报警。实验表明,给出的方法能够准确实现绊线检测。
During trip-line detection,Gauss model is used to model background,object is detected by background differencing.Scanning the set of points on the line,if object is detected,for double-direction trip-line detection,system directly alerts,but for single-direction trip-line detection,the moving direction of the object must be analyzed first.If the moving direction of the object matches forbidden passing rule,system directly alerts.The experiment shows that the method can detect trip-line event accurately.
