Monitoring method, computer program for realizing monitoring method, and monitoring system

摘要

Problem to be solved: to provide a technique for detecting floating objects while suppressing erroneous detection.The processing performed by the monitoring system isThe number of characteristic points included in the second region in the frame image is calculated (S130) andSetting the judgment reference a based on the optical flow (S135) andIn step S140, the judgment of the floating object is executed for each pixel in the frame imageThe ratio of the number of pixels determined as the floating object is calculated (s145) andUsed in a learned modelThe decision criterion B based on the number of pixels is set (S150);A judgment is made as to whether or not the judgment criterion a and judgment criterion B are satisfied (S160) andIt is determined that the floating object exists (S170) andA predetermined notification processing is executed (S180) andThe next frame image is set to the object of processing (S190).Diagram
