監視方法、監視方法を実現するためのコンピュータプログラム、および、監視システム
Document Type and Number:
Japanese Patent JP7083863
Kind Code:
B2
Abstract:
To provide a technology for early detecting a floating object while suppressing erroneous detection.SOLUTION: Processing executed by a monitoring system includes the steps of: calculating the number of feature points included in a second area inside a frame image (S130); setting a determination reference A based on an optical flow (S135); executing determination processing of a floating object for each pixel inside the frame image (S140); calculating a ratio of the number of pixels determined as the floating object (S145); setting a determination reference B based on the ratio of the number of pixels, used by a learned model (S150); determining whether or not the determination reference A and the determination reference B are satisfied (S160); determining that the floating object exists (S170); executing prescribed notification processing (S180); and setting a following frame image as a target of the processing (S190).SELECTED DRAWING: Figure 1
