What can 3D laser scanning do for us? Why is this application so popular and obvious? Let’s start with the basics, point cloud. We live in a multidimensional space, and the things in the space are closely related to everyone. With the development of technology, the way of using point cloud to express spatial information will become a part of our life. Next, let’s look at the benefits of this method in the raw state.
Advantages Of Using Cloud Point Of 3D Scanning Technology
Contactless information collection
Different application fields have different requirements for point cloud. For example, various problems are often encountered in geological research, landslide monitoring, hazard source detection, radioactive environment survey, cultural relics Archaeology and other operation projects. For example, the location of the inspection is difficult to reach, or there are potential safety hazards in the environment, or the object to be inspected should not be touched. It will be difficult to solve these problems through traditional methods, because when you take tape measure, protractor, compass, vernier caliper, rangefinder, theodolite, level, total station, GNSS, geological radar and other measurement, measurement and survey equipment to complete these tasks, you will find that there are many dangers, low efficiency, difficult information and even impossible to achieve!
Efficient access to information
The current scanner hardware can collect points from 10 to 1000000 per second according to different application requirements. In just a few minutes, the spatial information of the surrounding scene can be accurately collected. Collecting data by 3D laser scanning is unmatched by traditional methods in terms of efficiency. The point cloud can accurately reflect the spatial position, and the high-density point cloud with color value realizes the information visualization.
Since there is a bit of cloud, where is not allowed to point where, data application so easy! So far, it is not only efficient data acquisition, but also easy to “move” the real scene into the computer. This magnitude of data, no matter how refined the conventional measuring equipment, will take a lot of time to obtain completely. The efficient acquisition of point cloud can be described as a major revolution in the efficiency of 3D spatial information collection!
The information is comprehensive without omission
The implementation of digitization in real scenes is of great significance, which can be reflected in a variety of industries. For example, large factories collect data through three-dimensional scanning, which can be done once and for all. The complex factory assets can be seen at a glance, which is not only convenient for management and information transmission, but also can greatly avoid the endless information collection caused by insufficient data, so as to save time, manpower and capital investment.
3D laser scanning can provide quasi real-time point cloud information for constantly updating and changing factories, and deal with the continuous evolution of the factory. If the traditional 2D drawings want to reach the level of near real-time update, I’m afraid they will pay a great price Even though the design of many factories has adopted three-dimensional modeling design from the beginning, the local update of most factories during the operation period is difficult to follow up in the initial model at any time. This kind of problem is easy to cause the negligence of factory facility management, and it is easier to put emergency maintenance or local reconstruction and expansion in a place without reference basis. For large factories, the losses caused by shutdown due to failure are heavy.
Basic information archiving and browsing
As basic data, point cloud is widely used, and information archiving is needed everywhere: construction projects need to store completion information. Archaeological excavation needs to retain cultural heritage information. Criminal investigation and traffic accident investigation need to obtain first-hand on-site information. Resource mining needs to store the whole process information from exploration to mining and then to repair. The construction, operation and maintenance of factories and infrastructure need to store full life cycle information. Medical treatment and beauty need to store the comparison information before and after. Industrial production and processing need to store design and testing information. 3D imitation and 3D printing need to store the most precious original data information and so on.
Before being used for other purposes, point cloud can play a role that can not be ignored simply for browsing.
Many point cloud browsing software provide rich functions. Will there be an immersive feeling after opening point cloud information? The archived point cloud information can now vividly show their wonderful content. Some point cloud browsing software has video production function, which can make browsing video according to the path, speed and other parameters set by the operator, so as to transfer the results to others.
