3D scanners vary in type for different needs and uses. The most common types include structured light scanners, laser scanners, photogrammetry systems, handheld scanners, and LiDAR scanners. Each has unique features, accuracy levels, and use cases.
Structured light scanners project a pattern onto the surface of the object, which captures the distortion and builds a 3D mapping. For accuracy, it usually attains resolutions as fine as 0.05mm. Because of their precision, structured light scanners are widely used in quality control and reverse engineering. Devices such as the Revopoint Pop 2 avail themselves of this technology, hence giving reliable results that make professionals like them.
Laser scanners use a laser beam to sense the distance between the scanner and the object being measured. These measurements are then combined to create a point cloud and form a 3D model. They are very efficient in the capture of complicated geometries, capturing objects up to 10 meters away. Architecturally and industrially, laser scanners are very important for making detailed models of big structures.
A photogrammetry system relies on several high-resolution images taken from different perspectives. Advanced algorithms then reconstruct a 3D model based on these images. The process therefore provides an inexpensive solution for modeling large-scale environments, such as landscapes or archaeological sites. However, this approach, which is normally about 0.1mm in accuracy, relies enormously on the quality of the camera and lighting conditions.
Handheld 3D scanners are portable and flexible, allowing users to acquire information even in changing environments. These scanners weigh less than 1 kilogram and are useful in medical or other imaging for product design. In a survey taken in 2023, handheld 3D scanners accounted for 35% of the global market share of 3D scanners, indicating their ever-growing demand.
LiDAR scanners are devices that operate by sending out laser pulses to measure distances, thus enabling the creation of highly detailed 3D maps of large-scale environments. These are very important in industries such as self-driving cars and environmental studies, among others. LiDAR can scan at speeds up to 1 million points per second. For example, LiDAR technology mapped the Amazon rainforest and revealed human settlements that were buried under dense foliage.
As 3D scanning technology continues to improve, the solutions by different manufacturers balance affordability with functionality. Brands like Revopoint are very competitive, offering versatile solutions such as the 3d scanner that combines portability with precision. These developments make the technology more usable for hobbyists and small businesses.
With such a variety of 3D scanning devices, users are sure to find just the right device for them, whether it be for industrial design, cultural preservation, or everyday creative projects.
