3D scanning vs. traditional surveying methods

Today’s 3D scanners are small devices that can measure large-scale components. In addition, they are distinguished by the non-contact nature of their measurement data collection. With them, you can create 3D documentation in an efficient way. This type of equipment is also distinguished by its low weight, despite its rather sophisticated equipment in the form of a compass, altitude sensor and dual-axis compensator. As a result, 3D scanning services run extremely smoothly. What is worth knowing about this topic?

Highlights of 3D scanning

The described devices are very often used, for example, in surveying, to increase the detail and efficiency of measurements, as well as to improve the safety of workers operating in the field. An additional benefit is the savings in time and manpower, compared to traditional methods. 3D scanning enables scans of the entire field of view. As a result, an extremely dense point cloud of millions can be obtained. These are then used to map the scanned space and achieve an accurate appearance.

3D scanners are excellent for use in particularly hazardous locations such as steel mills, foundries, mines and other heavy industry workplaces. Services performed with a 3D scanner minimally affect the operation of factories and industrial facilities. This is because the data can be collected from a safe distance. This eliminates the need to use heavy scaffolding or safety harnesses. The devices do not require more than one person to operate. This is another difference from conventional (surveying) methods, which require teams of two. As a result, you can expect to reduce project costs and significantly reduce field time and obtain much more information. In addition, there is no need to arrange additional visits, as 3D scanning enables a virtual return to the location.

3D scanning vs. traditional methods

Traditional surveying methods have been used since time immemorial. As part of the development of technology, modern recording devices such as 3D scanners have significantly expanded the ability to acquire data over large areas. The following are examples of applications of 3D scanning technology in areas of industry previously reserved for traditional surveying: .

  • Taking detailed topographic measurements. They are the basis of technical plans, as well as planning and zoning in factories. Therefore, their accuracy and comprehensiveness are necessary. Detailed measurements of areas are the starting point for many other works such as planning upgrades or creating inventories.
  • Conventional methods of measuring mine shafts using total stations, for example, can be successfully replaced by a 3D laser scanner. Engineers are able to efficiently and accurately produce as-built documentation and create a detailed model of the shaft surface to analyze profile variation on the
    different heights. This gives us the ability to move the crane smoothly and avoid unwanted collisions.
  • Mention should also be made of as-built documentation, which applies to structures such as bridges or extensive pipelines in various types of processing plants. Surveying replaced by scanning performed with a 3D scanner allows to check the accuracy of the assembly of components, as well as confirm the correct geometric structure of the components.
  • Traditional surveying plays a very important role in the implementation of construction and mining projects, which require checking and controlling the volume of material. Using a 3D laser scanner, engineering teams acquire data from the location before excavating the ore and also after the work is completed. Exactly the same process can be used for quantitative analysis of heap (coal, sand, etc.) Such methods work very well for precise volume determination.

Being an alternative solution to traditional measurement methods, services performed with 3D laser scanners allow to collect more information about measured objects with greater precision in a shorter time. By simultaneously acquiring precise point cloud, panoramic images, RGB color, we can provide data that, when properly analyzed, far exceeds the resolution and performance of traditional methods.
