Use Case
The Shengxin Cathedral and its urban surroundings in Guangzhou (China) form a highly complex monumental complex. To plan conservation work and facilitate its documentation, a complete survey was required, both exterior and interior of the building.
The objective was to obtain a digital twin of the complex in the shortest time possible, taking advantage of mobile scanning technologies. The technical challenge was to manage a massive volume of data - more than 600 million points in total, according to the processed files - and transform them into useful information for the engineering and architecture team.

The scanning was carried out with OmniSLAM's R8+ scanner, which allows you to traverse the area in just a few minutes while simultaneously capturing points and images. After processing the data in OmniSLAM software, three LAS files were imported into Tcp PointCloud Editor.
To focus the analysis, the area of interest was delimited and noise points were removed using elevation selections and other tools. The source files were merged into a single cloud, and subsequently a density filter was applied to remove points that were too close together (less than 1 cm).
Point cloud processing with Tcp PointCloud Editor
To distinguish different objects, Tcp PointCloud Editor incorporated an artificial intelligence model trained for outdoor scenes. The software automatically classified the cloud, distinguishing ground, buildings, trees and other categories. This classification was refined with advanced selection tools.
Automatic classification using artificial intelligence
The project also took advantage of other software functionalities. Quick profiles were generated to examine cross-sections of the cloud, distances were measured and objects were drawn with CAD tools.
Floor plan section generation for vectorization
The images captured with the scanner were imported along with their position and orientation, allowing examination of the 3D trajectory and inspection of panoramic photographs.
Interior inspection with 3D trajectory and panoramic images
Finally, the cloud was published so that collaborators could explore it.
- Fast capture of interior and exterior
- Efficient cleaning processes
- AI classification with assisted editing for consistent results
- CAD drawing tools on the point cloud
- Image integration for visual inspection
- Web publishing for consultation and collaboration
This project demonstrates how the combination of the OmniSLAM R8+ scanner and Tcp PointCloud Editor provides a comprehensive solution for the survey and exploitation of point clouds in surveying, heritage and civil engineering projects.
