Grey scale pixel value, calculated level direction to the right apart from the gray value of pixel of its 3 pixels as right grey scale pixel value, when
The absolute value of the difference of upper grey scale pixel value and lower grey scale pixel value is less than or equal to threshold data and left grey scale pixel value and right pixel
The absolute value of the difference of gray value less than or equal to threshold data time, by for pixel be set to white level pixel, when upper picture
The absolute value of the difference of element gray value and lower grey scale pixel value more than threshold data or left grey scale pixel value and right grey scale pixel value it
Difference absolute value more than threshold data time, by for pixel be set to black level pixel, and output gray level image pair
The binary image answered；
Picture smooth treatment equipment, is connected with binary conversion treatment equipment, is used for receiving binary image, in binary image
Each pixel, when adjacent all pixels exist the trip point of more than half, then by for pixel
Gray value retains, otherwise, by for the gray value of pixel be set to white level pixel, and it is corresponding to export binary image
Smoothed image；
Wavelet filtering equipment, is arranged in the front end instrumental panel of steamer, is connected with image balance processing equipment, is used for receiving smooth
Image, performs 2-d wavelet Filtering Processing to obtain filtering image to smoothed image；
Sunlight area data extraction equipment, is arranged in the front end instrumental panel of steamer, is connected to obtain filter with wavelet filtering equipment
Ripple image；For each pixel in filtering image, when its gray value is at default sunlight upper limit gray value and default sunlight
Time between lower limit gray value, determine that it is sunlight pixel；By in filtering image all sunlight pixels form region from
Filtering image splits obtain each sunlight subimage；And determine that it is at filtering image based on each sunlight subimage
In position and calculate its area ratio occupying filtering image；Export the respectively corresponding position of each sunlight subimage and
The most corresponding area ratio.
