How Do Handheld 3D Scanners Work?<\/h2>\n\n\n\n
Stripped down to its most basic function, a handheld 3D scanner captures data from a real-world object, subject, or environment and then translates it into an accurate digital model. <\/p>\n\n\n\n
The captured data consists of an object\u2019s shape, texture, surface, and position within a defined visual field, which is then processed into a mesh or point cloud. The collected data is then imported to 3D modeling CAD software for editing and manipulation to suit a vast range of applications.<\/p>\n\n\n\n
Different 3D scanning technologies exist.<\/p>\n\n\n\n
In the case of handheld 3D scanners, there are two dominant ones. These are laser triangulation and structured light, both roughly based on the core concept of triangulation using an infrared laser or a pattern of light projected onto an object.<\/p>\n\n\n\n
The 3D scanner measures how the object deforms, distorts, and reflects the trajectory of the light emitted by the laser or light pattern to determine the distance to an integrated camera and then creates a 3D model.<\/p>\n\n\n\n
As the name implies, 3D scanners are untethered, handheld devices that require the user to scan an object from multiple angles to capture an accurate 3D model. <\/p>\n\n\n\n
That stands in contrast to hands-off stationary 3D scanners equipped with fixed sensors, cameras, and, often, a turntable to rotate the object automatically.<\/p>\n\n\n\n
Benefits of Handheld 3D Scanners<\/h2>\n\n\n\n
Portability and Versatility<\/strong> – Handheld 3D scanners can easily be moved around a busy workshop, manufacturing plant, design studio, or even used outdoors, or to scan tough-to-reach objects located in tight spaces. <\/p>\n\n\n\n Additionally, they can scan much larger objects than most stationary scanners.<\/p>\n\n\n\n User-Friendly<\/strong> – By design, handheld 3D scanners are much easier to use. Using the scanner generally comes down to pressing a trigger and moving about an object with minimal setup or prep work.<\/p>\n\n\n\n Some handheld 3D scanners emit visible light onto an object to give users a clear sense of what they are scanning at any given moment, which is helpful to capture a complete scan of an object or space.<\/p>\n\n\n\n Fast Scanning and Processing<\/strong> – Highly accurate, handheld 3D scanners offer solid scans the first time around, saving time and effort. Additionally, by scanning segments of an object at once instead of a specific point, the scanning process is speedy, crucial for fast-paced professional settings.<\/p>\n\n\n\n Affordability<\/strong> – Cost is always relative, but handheld 3D scanners require a much smaller investment, making them accessible to smaller businesses limited by a tight budget compared to industrial-grade stationary scanners.<\/p>\n\n\n\n Pros<\/p>\n\n\n\nBest Handheld 3D Scanners<\/h2>\n\n\n\n
