Capturing reality becomes the all purpose solution for AEC projects

The developments in technology and computer science change the course of our life. Between access and sharing of information, the new generation of technologies strengthens social ties and both personal and professional development.

The capture of reality in 3D is one of the advances in the technological sphere which improves the quality of professional services and the advancement of AEC projects. This process makes it possible to generate data by capturing and scanning a physical space which can be an industrial site, a factory, a building or a forest. The statement obtained can then be used for construction, design, renovation or even visualization and maintenance. As technological advances progressed, the capture of reality has become more and more necessary for the realization of various projects by users who formerly would have called on an expert.

the Principle of the 3D laser statement

The point cloud takes shape when making several scans of the physical space which must be aligned in order to represent reality as built in the way the way more precise possible. This “assembly” process is called. The scanners perform online aims and operate several scans in order to assemble them to create an environmental digital twin.

In some cases, GNSS (Global Navigation Satellite System) technology like GPS is used to align and properly superimpose scans thanks to scanners' position data. However, some more complex situations make the use of GPS data impracticable. In these cases, the user of the computer software analyzes the data of the point cloud and finds geometric similarities of the physical space in order to align and superimpose the different scans.

two methods are then used to assemble these scans. The first is the use of targets, artificial objects reducible in points recognizable by the point cloud software. At least three targets are positioned according to a location determined in the environment for at least two scans. The software user can then recognize objects and align scans according to the targets reduced to points. This technique remains longer to perform because it requires qualified personnel on the ground to place targets in strategic places and change them depending on the scans to be performed. In addition, a variety of natural or artificial obstacles can be found within the environment to note which complicates the task and requires more time and labor.

The second method is based Only on the use of software that assembles scans without geometric landmarks posed manually. The process then requires rigor and meticulousness during the superposition of the statements.

scan differently

The way of scanner and the material used import Little to obtain an analyzable and visualizable point cloud. 3D digitization is done in the same way but it is the processing of information that is different during the scan phase. Each statement material has its specific utility. Some make it possible to scan with more precision, others with more speed.

Terrestrial laser or Lidar laser scanners operate by light impulses in order to recover information on surfaces and the environment. The 3D data is then captured to form a cloud of points. It derives its performance during surveys of interior spaces, external facades and MEP components difficult to visualize.

Mobile laser scanners are terrestrial surveying tools that use a mobile laser on the move, or Mounted on a vehicle, transportable on foot. It is useful for scanning more quickly, while moving, simpler infrastructure because indeed, its precision is less compared to that of a terrestrial scanner.

Photogrammetry is a method that requires the 'Using drones equipped with high resolution cameras which creates a geometric photo with a uniform scale where you can measure real distances like a card. These speech therapy makes it possible to collect information on difficult to access areas or to cover potential black dots.

an essential technology for the development of ACE and industries

Before starting a renovation, the laser operates in order to scan construction conditions to compare the real environment to design and facilitate project planning. It is a process that AEC companies particularly like by considering the capture of reality as essential in their design, construction and even relationships with their customers because the way the projects are executed changes fundamentally and The way of interacting with customers as well. The capture of reality is necessary to view the final project, perceive its added value and its potential in order to carry it out correctly.  

A concrete example is that of the Penn State University. University officials expressed their concern linked to the configuration of their intramural climbing wall and building materials. They then turned to the capture of reality in order to find solutions to their problem. They then resized the wall and selected the most suitable products for its construction.

of many AEC companies enter the field of reality and highlight the use of scanners 3D lasers for the execution of projects. They deploy scanners with a view to capturing the conditions of the environment and controlling the progress of current work.

The point cloud acts as a central stone in the middle of all stakeholders From a project which gives them a way to simulate future work.

in the end, AEC companies are counting on a precise scan which will serve as aid for modeling and decision -making in the field or at the office. It is therefore a technology that benefits all stakeholders in a project.

This technique of capturing reality can be all the more effective if it is combined and associated with Other data processing solutions, analysis and exploitation of points clouds.

reality, associated with data exploitation, form the miracle solution together for ACE companies

Capture reality, digitizing data and assembling a point cloud is not enough because there is no end user. To give meaning to all this, it is imperative to extract from data, generate information and transmit it. It is at this point that digitization makes sense and that the exploitation of the point cloud is real. By viewing a cloud of points in virtual reality, the planning of a project and the sharing of the raised data goes from two -dimensional to interactive.

The capture of reality becomes a standard for creators, designers and other AEC actors as well as the new tools that promote immersive collaboration to increase the commitment of all the stakeholders of the project. It also becomes an added value for commercial solutions and creates link between companies, their users and their customers by allowing them to benefit from a fast, efficient, precise and more than reliable service.
