Abstract: A method and device for real-time measuring sunlight on buildings,comprises: receiving training satellite images of training buildings, analyzing training satellite image features, extracting training building outline information, training building height information and training information of profile sunlight map sequence of corresponding continuous height; according to the preset training latitude and longitude range, obtaining the corresponding training building outline information, training building height information and training information of profile sunlight map sequence of corresponding continuous height; and training to obtain a 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

Abstract: A building design method, device, system and storage medium, which obtains the location information of the target cadastral land parcel, and based on such location information, obtains peripheral information of the target cadastral land parcel such as the economy information, community information and transportation information, and based on such economy information, community information and transportation information, controls the cadastral land parcel evaluating device to generate multiple data models of the target cadastral land parcel; such multiple data models comprise economic vitality model, economic value model, noise analysis model and viewshed analysis model, then obtains the indicator data of the target cadastral land parcel such as floor area ratio, land area, city, land usage, functional composition, and the building density, and finally controls the scheme generating device to generate multiple building design schemes based on the data model and the indicator data.
