摘要
为了在序列图像或视频流中定位移动目标,对相邻图像求差,结果经过形态学滤波后闭合边缘,填充内部区域,最后判断图像中是否存在目标,如存在则报警并记录图像。运用虚拟仪器软件(LabVIEW)平台,配合硬件设施实现系统功能。此方法简便可靠,对图像或视频中运动目标定位效果良好。
In order to get the difference of the jointed two images in the image sequence or vision stream,the difference is processed by morphologic filter,Then,the edge of the result is closed and the object area is filled.At last,an alarm is given if there is object in the images by the estimation method,The system is established on the LabVIEW flat assisted by hardware,The monitoring method is simple and efficient,Its effect is satisfied.
