Method and device for real-time measuring sunlight on buildings

A device for real-time measuring sunlight on buildings, characterized in that, comprises:

• a sunlight training data acquisition module, a sunlight training module of testing model and a real-time building sunlight measurement module;
• wherein
• the sunlight training data acquisition module described above, connected to the sunlight training module of testing model, receiving training satellite images of training buildings, analyzing the training satellite image features, extracting the training building outline information, training building height information and training information of profile sunlight map sequence of corresponding continuous height;
• the sunlight training module of testing model, connected to the sunlight training data acquisition module and the real-time building sunlight measurement module, according to the preset training latitude and longitude range, the corresponding training building outline information, the training building height information and the corresponding training profile sunlight map sequence information are obtained and trained to obtain the sunlight testing model;
• the real-time building sunlight measurement module, connected to the training module of sunlight testing model, receiving target location information of the cadastral land parcel to be measured, obtaining corresponding target latitude and longitude according to the target location information;
• receiving target building outline information and target building height difference information of the cadastral land parcel to be measured, and obtaining a sequence of sunlight maps of the buildings within cadastral land parcel according to the sunlight testing model.
