About three-dimensional laser scanning technology
Three-dimensional laser scanning technology is also called real-scene reproduction technology. This technology integrates optical, mechanical, electrical and computer technologies. Its importance lies in its ability to convert the three-dimensional information of real objects into digital information that can be directly processed by computers, providing a more convenient and faster means for digitizing real objects, breaking through the traditional single-point measurement method. Due to its non-contact nature, Penetrating and digital characteristics enable high-density, high-precision, and automated measurement of real objects. It can actively, quickly, real-time, and dynamically scan three-dimensional point cloud data on the surface of objects, and can be used to obtain high-precision and high-resolution data. digital reality object model.

About BIM technology
BIM, which is building information model , can simulate the real information of buildings through digital information simulation, and plays an important role in improving production efficiency, saving costs and shortening the construction period. .
In recent years, the application of BIM technology has penetrated into all aspects of engineering design, construction and management. BIM technology can transform specific data into three-dimensional architectural models and conduct previews of various aspects of building a house. In the practical application of BIM, the interconnection and update between real-time data on the construction site and the building information model is a difficult point. There are problems such as difficulty in detailed data survey and low accuracy. Three-dimensional laser scanning technology solves this difficulty. The advantages of combining
BIM technology with 3D scanning technology
BIM technology is the construction of building information models before the implementation of construction projects, while 3D laser scanning technology is the digitization of three-dimensional information of real objects.
BIM has the characteristics of visualization, coordination, optimization, simulation and visual graphics, and the data obtained by 3D scanner is very real and accurate, which can be described as a "perfect partner" in current factory modeling.
1. On-site data collection
Three-dimensional laser scanning is a "real scene replication" technology. Under the premise of ensuring the scanning accuracy, the selected engineering parts can be completely and realistically collected through scanning.
2, three-dimensional laser scanning data application
The point cloud data generated by three-dimensional laser scanning can be converted into BIM model data after being processed by professional software, and then can be immediately compared with the designed CAD model and BIM model for accuracy to find the construction site and design Differences in models.
3. Unified data management method
After data collection and conversion, the on-site situation can be completely integrated in the unified and integrated information platform in the form of BIM model and point cloud model, and relevant management work can be carried out according to the needs of on-site technicians.
BIM+ Advantages of 3D laser scanning in factory modeling
1. Make data more intuitive
Since the data output by 3D laser scanning technology is three-dimensional, it can be perfectly combined with BIM technology, allowing the expression form of surveying and mapping results to change from a single topographic map. Create three-dimensional maps, flat, vertical and cross-sectional views and establish three-dimensional models. And because the model is a three-dimensional expression, we can study the details of the building structure from a more intuitive and subtle perspective, thereby promoting the optimization of the construction process and improving the quality of the overall building.
2. Improve modeling efficiency and accuracy
Compared with traditional measurement technology, 3D laser scanning technology breaks through the limitations of the traditional single-point measurement mode. The measurement speed can reach 1000 points/second, and it only takes In a few hours, even complex buildings can be accurately expressed, with the advantages of high efficiency and high precision.
In addition, 3D laser scanning can also obtain all point data of the building space and build a real-time database of the building. This database can not only assist in the establishment of building models, but can also be used for construction node comparison, BIM model correction, data retention, etc., greatly improving Improve the efficiency and accuracy of building models.
3. Save manpower and have a wide range of applications.
The entire measurement process is carried out under non-contact conditions. This not only saves manpower, but also effectively avoids damage to the building by human factors. It also expands the measurement range to areas where people cannot Arriving in dangerous environments.

The industrial industry has brought new modeling methods and promoted the development of factory digitalization and intelligentization.
Application of BIM+ 3D laser scanning in petrochemical enterprises
In recent years, the Ministry of Natural Resources has successively released the "National Basic Surveying and Mapping Center" Long-term Planning Outline (2015-2030)", "Real 3D China Construction Technical Outline (2021 Edition)", "New Basic Surveying and Real 3D China Technical Documents", "Notice on Comprehensively Promoting Real 3D China Construction" and a series of documents , to promote the construction of real-life three-dimensional scenes.
Jinma Company follows the policy pace and actively explores the application of BIM and 3D scanning technology in the real-life 3D model of the factory.
The equipment in petrochemical enterprises is complex, the pipelines are crisscrossed, and the objects to be managed are densely arranged in space. Traditional two-dimensional flat diagrams cannot meet the needs. However, through BIM and 3D laser scanning, petrochemical equipment can be obtained quickly, accurately and conveniently 3D spatial information of physical objects (equipment, pipe network, frame) and construct a real-life 3D model. It has broad application prospects in petrochemical enterprises.
