摘要
The invention relates to a device for monitoring the absence of motionless bodies in a swimming pool. Two cameras (1) provide for the permanent imaging of the bottom of the swimming pool. These images are first digitized and then processed by a computer. The superimposition of the two information permits analysis of substantially the entire the surface of the swimming pool in order to determine if a portion is masked by an obstacle. When such obstacle is detected, the duration of the presence of each masked pixel is analyzed. After a certain time delay, and for a minimum number of neighboring pixels, an alarm is generated.
