Abstract

The invention discloses a BIM (Building Information Modeling)-based 3D (Three-Dimensional) scanning method. The method comprises the following steps: setting instrument working data according to characteristics of a scanned target object; performing target distribution measurement, measurement control network distribution and scanning station distribution according to the characteristics; performing point cloud data acquisition and texture image data acquisition on the target object; and carrying out data preprocessing and result production according to the collected data. According to the invention, the scanned image can be accurately and clearly obtained.

Description

technical field [0001] The invention relates to the technical field of data modeling, in particular to a BIM-based 3D scanning method, storage medium and computer equipment. Background technique [0002] 3D scanning is a high-tech that integrates optical, mechanical, electrical and computer technologies. It is mainly used to scan the spatial shape, structure and color of objects to obtain point cloud data that fully reflects the feature information of buildings. Analyzing and constructing a three-dimensional image provides information and data support for the construction scheme design. In the prior art, since the scanned objects each have their own characteristics, the used 3D scanning method cannot set a corresponding scanning method according to the characteristics of the scanned object to obtain an accurate and clear scanned image. SUMMARY OF THE INVENTION [0003] The present invention provides a 3D scanning method based on BIM, which can obtain scanned images accura...
