3D laser scanning is a popular technique widely used in engineering, construction, and manufacturing to create digital models of physical objects and spaces.
What is 3D Scanning?
3D scanning is a technology that uses lasers or structured light to capture detailed measurements of an object or environment. These measurements are then used to create a digital model of the object or space. 3D scanning has numerous applications in industries such as engineering, construction, and manufacturing, and it is a valuable tool for creating accurate and detailed digital representations of physical objects and spaces. There are several different types of 3D scanners, each with its own specific capabilities and applications. In this article, we will explore the different types of 3D laser scanning and their uses.
Terrestrial 3D Laser Scanning
Terrestrial 3D laser scanners are mounted on tripods and are used to scan objects and environments that are within a few meters of the scanner. These scanners are portable and can be easily set up on site. They are often used to scan buildings, infrastructure, and landscapes, and they can capture detailed measurements of a wide range of objects and spaces.
Handheld 3D Laser Scanning
Handheld 3D laser scanners are small, lightweight scanners that are held in the hand and can be used to scan objects and environments from any angle. These scanners are particularly useful for scanning small or complex objects, as well as objects that are difficult to access with larger scanners. They are often used in manufacturing, inspection, and quality control applications.
Mobile 3D Laser Scanning
Mobile 3D laser scanners are mounted on vehicles, such as cars or drones, and are used to scan large areas or environments. These scanners are particularly useful for scanning large or hard-to-reach areas, such as roads, bridges, and pipelines. They are often used in engineering, construction, and maintenance applications.
Structured Light 3D Laser Scanning
Structured light 3D laser scanners use a pattern of light, rather than a single laser beam, to capture measurements. These scanners are typically more accurate than other types of laser scanners, but they are also more expensive and require a stable environment to work correctly. They are often used in manufacturing, inspection, and reverse engineering applications.
Why do We Need Different Types of 3D Scanning
There are different types of 3D scanning to meet the specific needs and requirements of different projects and applications. Each type of 3D scanner has its own specific capabilities and limitations, and the best type of scanner for a particular project depends on the size and complexity of the object or environment being scanned, as well as the accuracy and resolution required.
For example, terrestrial 3D laser scanners are mounted on tripods and are best suited for scanning objects and environments that are within a few meters of the scanner. These scanners are portable and can be easily set up on-site, making them a good choice for a wide range of applications.
Handheld 3D laser scanners, on the other hand, are small and lightweight and can be used to scan objects and environments from any angle. These scanners are particularly useful for scanning small or complex objects, as well as objects that are difficult to access with larger scanners. They are often used in manufacturing, inspection, and quality control applications.

Conclusion
3D laser scanning is a versatile technology with a wide range of applications. The type of 3D laser scanner used depends on the specific needs of the project, including the size and complexity of the object or environment being scanned, as well as the accuracy and resolution required.
