Case Studies
Large-scene three-dimensional scanning is widely used in cultural relics protection, urban building surveying, topographic mapping, mining industry, deformation monitoring, factories, large structures, pipeline design, aircraft and shipbuilding, highway and railway construction, tunnel engineering, bridge reconstruction and other fields.
Laser 3D scanning of large scenes can reach millimeter-level accuracy. Take the protection of cultural relics as an example. Application in the protection of cultural relics: 3D laser scanning of large scenes is mainly for ruins, ancient buildings, sculptures, etc. The development of human society has left many precious cultural relics, natural and cultural landscapes. With the passage of time, these heritages have been severely weathered and become incomplete, and some have even begun to disappear. In order to protect and restore these heritages, three-dimensional laser scanning Provides brand-new technical means, can obtain the geometric and texture information of cultural relics, and store and manage digital information.
The three-dimensional laser scanning system can provide true three-dimensional, true-size data model of factory transformation, which can speed up the design progress and obtain the best design plan for the enterprise.
Three-dimensional scanning technology collects the spatial structure information and construction information of ancient buildings into the computer with a data collection volume of nearly one million points per second.
In order to fully preserve the most complete and accurate three-dimensional data of Yingxian Wooden Pagoda, large-space three-dimensional scanning technology was adopted for the implementation of this project.
The 3D point cloud data can provide an intuitive scene scene for subsequent analysis. High-precision point cloud data can highly restore the on-site environment
Using point cloud data to automatically detect and measure the cross-sectional dimensions of the bridge main girder and improve the efficiency of construction management.
The team used three laser scanners to perform a comprehensive scan, and then formulated a feasible construction plan based on the collected point cloud data.
For the 3D data collection of large-scale archaeological sites, ancient villages and historical buildings, the 3D surveying and mapping of large-scale factories, infrastructure projects, and bridge pipelines all require large-scale laser scanning equipment to provide services.
Large-size laser scanning does not require contact with the scanned object. It can perform panoramic scanning at a long distance, and can perfectly splice multi-point scanning data of the same scene, and finally output a complete 3D point cloud data or 3D model.
Many historical buildings are ancient. Some stone carvings and wood carvings have been weathered and damaged, and some beams, columns, and tenon joints have been distorted and deformed, and even many ancient villages have been on the verge of collapse. The large-scene scanning technology can be used without touching the scanned object. , Complete the acquisition and modeling of 3D data in the context of the scene, and provide perfect data support for the 3D archiving of ancient buildings, CAD data output, repair plan discussion, online display, simulation and other purposes.
With the migration of time, many large factories have made several technical improvements, and the actual factory drawings are completely different from the original drawings at the beginning of the factory. Many bridges, dams, and archways have also been deformed over time. These are hidden safety hazards. The data obtained by scanning large scenes, archiving, comparative analysis, and danger warning are of very practical significance.
3D laser scanning technology stands out due to its high efficiency, accuracy and non-contact advantages. Its application directions for large scenes are as follows:
Delivery within 30 days after the scan is completed, and a variety of data formats are available.
