DISTRIBUTED AUTOMATIC NOTIFICATION METHOD FOR ABNORMALITY IN REMOTE MASSIVE MONITORS

摘要

The present invention discloses a distributed automatic notification method for abnormality in remote massive monitors. If a data stream is not available, a disconnect prompt stream is generated. The data stream is converted to a continuous video. Then, the continuous video is divided into a plurality of single-frame images along the time axis, and each single-frame image is divided into a plurality of image grids. A plurality of pixels are next selected from each image grid. According to a plurality of image parameter values corresponding to the plurality of pixels, a statistical value of image grid parameter is calculated. Then whether an image grid is monochromatic can be judged according to the statistical value of image grid parameter. When a plurality of continuous single-frame images are judged to be monochromatic single-frame images, the color of the monochromatic single-frame images can be further judged.

1. A distributed automatic notification method for abnormality in remote massive monitors, comprising steps of:
acquiring a data stream from a monitor; converting said data stream to a continuous video; dividing said continuous video into a plurality of single-frame images along the time axis; dividing each said single-frame image into a plurality of image grids; selecting a plurality of pixels from each said image grid, and calculating a statistical value of image grid parameter according to a plurality of image parameter values corresponding to said plurality of pixels; judging if each said image grid is a monochromatic image grid according to said statistical value of image grid parameter; judging if each said single-frame image is a monochromatic single-frame image according to if said plurality of image grids are monochromatic image grids; and determining that said monitor is abnormal when a plurality of continuous single-frame images are judged to be monochromatic single-frame images.
