| description | The invention relates to a virtual construction sand table construction method and device based on three-dimensional GIS and BIM integration, computer equipment, a storage medium and a computer program product. According to the invention, the model precision of the virtual construction sand table can be improved. The method comprises the following steps: acquiring aerial picture information and image control point information of a target measurement area; carrying out aerial triangulation calculation according to the aerial photo information to obtain a three-dimensional model corresponding to the target measurement area; importing the image control point information into the three-dimensional model, and correcting the three-dimensional model after the image control point information is imported; carrying out secondary aerial triangulation calculation on the corrected three-dimensional model, and constructing a corresponding GIS space model according to a secondary aerial triangulation calculation result; obt |
