Building construction monitoring data intelligent analysis and early warning system

The invention relates to the technical field of image data processing, in particular to a building construction monitoring data intelligent analysis and early warning system. The system obtains a grayscale image of each frame of image in a video; acquiring the optical flow of the pixel points according to the adjacent grayscale images; dividing a direction interval according to the direction of the optical flow, and obtaining a characteristic optical flow according to the optical flow in the direction interval; sorting the feature light streams to obtain a motion feature sequence of the sliding window area; according to the motion feature sequence of the adjacent sliding window area, obtaining a motion dramatic change coefficient of the sliding window area, and determining a motion area; obtaining the change entropy of the grayscale image according to the motion sudden change coefficient of the sliding window area in the motion area and the distribution index of the direction interval; obtaining a time sequen
