The invention discloses a house type
structure analysis method and device. The method comprises the steps: S1, obtaining three-dimensional
object point cloud data and three-dimensional air
point cloud data; S2, identifying the three-dimensional
object point cloud to obtain a furniture
point cloud, performing two-dimensional object projection on three-dimensional
object point cloud data to obtain a rotation correction matrix, and performing rotation correction on the three-dimensional object
point cloud, the three-dimensional air point cloud and the furniture point cloud according to the rotation correction matrix; S3, generating an anti-interference two-dimensional overlook angle object projection and a normal
vector projection by combining the corrected three-dimensional object point cloud and furniture information to which each point belongs, and respectively generating a two-dimensional room
mask, two-dimensional angular points to which each room belongs, and relevance between the angular points; S4, generating local boundaries of the rooms and global boundaries of the floors according to the angular points, and performing optimization based on the angular points and the parallel distances of the boundaries; and S5, integrating furniture position and channel position information to generate a two-dimensional house type structure.
