Embodiment Construction

[0027] Such as figure 1 Shown, the present invention will be further described below in conjunction with accompanying drawing.

[0028] Step 1: Create a BIM deepening model of steel castings, the model depth reaches LOD300, and output the detailed design drawings of steel castings through the BIM model for use by the processing plant.

[0029] Step 2: Make wooden molds for steel castings based on the BIM model of steel castings and the detailed design drawings.

[0030] Step 3: Use a handheld 3D laser scanner to scan the wooden mold model. The handheld 3D laser scanner can scan the real object and then inversely image it to generate a spatial 3D surface model with an accuracy of 0.1mm, that is, the scanned model of the wooden mold of the cast steel.

[0031] Step 4: Fit and analyze the scanned inverse imaging model of the wooden mold of the steel casting and the BIM model of the steel casting. The system performs calculation and analysis on the spatial three-dimensional mask ...

Abstract

The invention discloses a cast steel member detection method based on BIM technology. The method is characterized by outputting the profile map of any position by creating a cast steel member BIM deepening model in order to facilitate design idea grasp for technical workers and increase cast steel member processing efficiency; scanning and detecting a cast steel member wood model and a cast steel member product by using a handheld 3D laser scanner with precision of 0.1mm, generating a spatial 3D model by inverse imaging and performing theoretical BIM model fitting analysis; expressing a detection result in the spatial 3D model in a chromatogram way, outputting single-point area deviation values, deviation trend, and an error range, achieving clear deviation value, and significantly increasing measurement efficiency. The method increases the processing efficiency of the cast steel member, prevents a waste of field construction resource due to processing errors, and provides protection for field installation.

Description

technical field [0001] The patent of the present invention relates to the technical fields of building information model application, virtual reality, and reverse forming, and specifically relates to a method for detecting steel castings based on BIM technology, and a method for detecting and managing steel castings based on three-dimensional laser scanning and reverse forming technology. Background technique [0002] Steel castings are often used to solve complex, abnormal-shaped, and difficult-to-manufacture joints in steel structure engineering, but the inspection and acceptance of complex and abnormal-shaped components has always been a difficult point in construction management. [0003] In the traditional steel structure project management, the total station is used to check the size of steel castings, such as dot setting-out or ruler, but there are large errors in dotting and projection setting-out, and the measurement error is even more serious for the ports of steel ...
