Wiener filtering equipment, it is connected with image balance processing equipment, for receiving smoothed image, wiener filter is performed to smoothed image
To obtain filtering image, wherein Wiener filtering is handled for causing the mean square error of smoothed image and filtering image minimum for ripple processing
To remove the white noise and speckle noise in smoothed image；
Solar data analytical equipment, it is connected with Wiener filtering equipment to obtain filtering image；For each in filtering image
Pixel, its gray value is matched with default sunlight tonal range, when its gray value is in default sunlight tonal range,
Determine that it is sunlight pixel；The region that all sunlight pixels in filtering image form is split from filtering image
To obtain each sunlight subgraph；And its position in filtering image is determined based on each sunlight subgraph and calculates it
Occupy the area ratio of filtering image；Export area ratio corresponding to position corresponding to each sunlight subgraph difference and difference
Rate；
