The gray value of the pixel of its 3 pixels calculates vertical direction downwards apart from its 3 pixels as upper grey scale pixel value
The gray value of pixel as lower grey scale pixel value, calculated level direction to the left apart from its 3 pixels pixel gray scale
Value be used as left grey scale pixel value, calculated level direction to the right apart from its 3 pixels pixel gray value as right pixel
Gray value, when upper grey scale pixel value and the absolute value of the difference of lower grey scale pixel value are less than or equal to threshold data and left grey scale pixel value
When being less than or equal to threshold data with the absolute value of the difference of right grey scale pixel value, by for pixel be arranged to white level pixel
Point, when upper grey scale pixel value and the absolute value of the difference of lower grey scale pixel value are more than threshold data or left grey scale pixel value and right pixel
When the absolute value of the difference of gray value is more than threshold data, by for pixel be arranged to black level pixel, and output gray level
Change binary image corresponding to image；
The sub- equipment of picture smooth treatment, it is connected with the sub- equipment of binary conversion treatment, for receiving binary image, for binary picture
Each pixel as in, when more than half trip point in adjacent all pixels point be present, then by for pixel
The gray value of point retains, otherwise, by for the gray value of pixel be arranged to white level pixel, and export binary image
Corresponding smoothed image；
Data merge equipment, positioned at high in the clouds, are connected with M high in the clouds application apparatus, for by the figure of each high in the clouds application apparatus
As the smoothed image that the sub- equipment of smoothing processing exports is spliced to obtain smooth integration image；
Wavelet filtering equipment, it is arranged in the Background control room of projection room, merging equipment with data is connected, smooth whole for receiving
Image is closed, 2-d wavelet filtering process is performed to smooth integration image to obtain filtering image；
Sub-screen area splitting equipment, it is arranged in the Background control room of projection room, is connected with the sub- equipment of wavelet filtering to obtain
Filtering image, filtering image is matched to detect and be partitioned into filter with the screen pattern of the various mobile terminals prestored
Each screen subgraph in ripple image, for each screen subgraph, pin is determined for its position in filtering image
To screen subgraph corresponding to seat numbering；Wherein, for screen subgraph corresponding to seat numbering hold and be directed to
Projection room seat numbering corresponding to screen subgraph where the spectators of mobile terminal；
Each screen subgraph and real-time scene image are carried out content matching to determine content matching hundred by Content analysis apparatus
Ratio is divided to specifically include：Each pixel in real-time scene image and each pixel of each screen subgraph are subjected to pixel value
Matching, the quantity of the pixel value pixel that the match is successful is more, and content matching percentage is higher corresponding to screen subgraph；
The gray value of black level pixel is 0.
