1. A floor plan image generating method, comprising:
acquiring a boundary of a target building and a layout constraint of the target building, the layout constraint comprising room types, room quantities, room locations, and adjacency relations between rooms;
outputting multiple first floor plan images according to the layout constraint of the target building;
selecting multiple second floor plan images from the multiple first floor plan images, and a matching degree between a boundary of each of the multiple second floor plan images and the boundary of the target building satisfying a preset condition;
for each of the second floor plan images, applying a layout constraint of each of the second floor plan images to the boundary of the target building, and obtaining a layout of the target building corresponding to each of the multiple second floor plan images; and
for each layout of the target building, inputting the layout of the target building and the boundary of the target building into a floor plan image generating network, and obtaining a predicted floor plan image of the target building outputted by the floor plan image generating network, wherein the predicted floor plan image comprises a room bounding box of each room in the target building and a positional relation of each room bounding box in the boundary of the target building.
