Urban generation point cloud-based surface temperature prediction method and device, medium and equipment

The embodiment of the invention provides a surface temperature prediction method and device based on city generation point cloud, a medium and equipment. The method comprises the following steps: generating a three-dimensional point cloud corresponding to a target city according to an obtained digital surface model and a building model of the target city; determining a geographic semantic tag corresponding to each point in the three-dimensional point cloud according to the ground feature distribution of the target city; for each region obtained by dividing the three-dimensional point cloud according to a predetermined size, constructing a geographic feature distribution matrix corresponding to the region according to the geographic semantic tag and the height information corresponding to each point in the region; and acquiring atmospheric state data of the region, and inputting the geographic feature distribution matrix, the digital surface model and the atmospheric state data corresponding to the region into
