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.
