Embodiment 1

[0030] An image-based method for creating crack visualization in bridge BIM models, such as figure 1 As shown, the present embodiment includes the following steps: S1: On-site collection and marking of crack information of bridge components, taking pictures of cracked bridge components perpendicular to the surface of bridge components, the crack information of bridge components includes: crack width, crack endpoint and bridge component The relative position of the members and the distance between the start and end of the crack.

[0031] S2: Import the photo obtained in step S1 into the 3D model of the bridge member, adjust the size of the photo, draw a crack extension sketch, use visual modeling software to extract the crack extension sketch and convert it into a polyline, such as figure 2 As shown, the method for adjusting the size of the photo is: adjust the size of the photo so that the distance between the starting point and the ending point of the crack in the coordinate...

Abstract

The invention relates to the technical field of bridge maintenance, in particular to an image-based bridge BIM model crack visualization creation method, which comprises the following steps of S1, collecting crack information, and shooting a crack picture; S2, importing the photo into a three-dimensional model, adjusting the size of the photo, drawing a crack extension sketch and converting the crack extension sketch into multiple lines; S3, extracting a three-dimensional model of the bridge member, and establishing a local coordinate system at a crack endpoint position; s4, transferring the multi-segment line into a local coordinate system to obtain a lofting path; s5, drawing a crack cross section profile diagram to obtain a lofting profile; s6, generating a crack solid model; and S7, importing the crack solid model generated in the step S6 into a three-dimensional model of the bridge member to obtain a bridge member BIM model with cracks. The method has the substantive effects thatthe crack information is collected on site, the bridge component BIM model with cracks can be obtained through simple processing, modeling is simple and rapid, and bridge maintenance can be assisted.

Description

technical field [0001] The invention relates to the technical field of bridge maintenance, in particular to an image-based method for creating crack visualization in a BIM model of a bridge. Background technique [0002] Bridges generally refer to structures erected on rivers, lakes and seas to allow vehicles and pedestrians to pass smoothly. In order to adapt to the modern high-speed development of the transportation industry, bridges are also extended to buildings that cross mountain streams, poor geology or meet other transportation needs to make traffic more convenient. A bridge is generally composed of a superstructure, a substructure, a support and ancillary structures. The superstructure is also called a bridge span structure, which is the main structure for crossing obstacles; the substructure includes abutments, piers and foundations; Or the force transmission device installed at the supporting place of the bridge abutment; the auxiliary structures refer to the bri...
