High-definition image collecting device, it is arranged in steamer, in front of steering position, for carrying out IMAQ to steering position scene
To export high-definition image；
Sunlight area data extraction equipment, is connected with medium filtering device network to obtain filtering image；For in filtering image
Each pixel, when its gray value is between default sunlight upper limit gray value and default sunlight lower limit gray value, it is determined that
It is sunlight pixel；The region that all sunlight pixels in filtering image form is split from filtering image to obtain
Obtain each sunlight subgraph；And determine its position in filtering image based on each sunlight subgraph and calculate it to occupy
The area ratio of filtering image；Export area ratio corresponding to position corresponding to each sunlight subgraph difference and difference.
