Abstract

The present invention relates to a computer-implemented method 1 for generating a parametric model 13 of a physical structure 36 based on point cloud data, the point cloud data describing a point cloud comprising points 14 acquired in an environment 34 in which the physical structure 36 is located, wherein the physical structure 36 comprises a plurality of parts, wherein the plurality of parts are arranged as an interconnected chain of parts that are physically connected, the method 1 comprising: acquiring the point cloud data 100, the point cloud data comprising geometry information of the environment 34; acquiring geometry information of a set of predefined geometric shapes related to the plurality of parts 200; performing a classification on the point cloud data 300 to detect parts of the plurality of parts in the point cloud data 301 based on the geometry information; assign to each detected part of the plurality of parts a set of points of the point cloud 302; and detect physical connections 5 of two or more detected parts 2, 3 of the plurality of parts 303; and generating 400 a parametric model 13 of the physical structure 36 based on the detected physical connections 5 of the two or more detected parts 2, 3 of the plurality of parts and the geometry information of the set of predefined geometric shapes, wherein the method 1 further comprises deriving geometric parameters 23, 24, 29 for each detected part 2, 3 of the plurality of parts from the geometry information of the set of predefined geometric shapes, wherein generating 400 the parametric model 13 of the physical structure 36 is further based on the derived geometric parameters 23, 24, 29 for each detected part 2, 3 of the plurality of parts, wherein at least one of the derived geometric parameters 23, 24, 29 of a preceding part 2 is used as a constraint for at least one of the geometric parameters 23, 24, 29 of a subsequent part 3 physically connected to the preceding part 2.
