Types of 3D scanner handhelds

With the advantages and increasing uses of 3D scanners handheld, many industries are now using this technology. This includes the construction, heritage, and healthcare industries, to name a few. The need for better 3D scanning solutions has led to the development of different types of handheld 3D scanners. The goal is to accurately and efficiently create high-quality 3D models of various objects.

Generally, 3D scanners handheld can be classified based on the technology used to capture the shape of the objects and area being scanned.

• Laser Handheld Scanners: Laser handheld 3D scanners use a precise laser beam to measure the distance between the scanner and the object's surface. The laser beam is usually pointed at the target from different angles to get a highly accurate point cloud. This type of scanner provides users with accurate data for complex shapes and details.
• Structured Light Handheld Scanners: These handheld 3D light scanners project a pattern of 2D light onto the surface of an object. Then, a camera in the device captures the deformation of the projected pattern to create a 3D model of the object. Scanners that use structured light work very well for objects that have complex shapes and details. They are known for their precise measurements.
• Simultaneous Localization and Mapping (SLAM) Handheld Scanners: SLAM handheld scanners use a combination of technologies, like laser scanning or structured light, along with an inertial measurement unit (IMU). These scanners can build a map of an environment or area while keeping track of their location at the same time. This enables them to scan large spaces or environments without the need for GPS.

Functions & Features

• Handheld 3D scanners are portable and designed to create 3D models by scanning objects. They are user-friendly and easy to operate, making it feasible for users to obtain 3D models of desired objects.
• Closed-loop scanning refers to the capability of the handheld 3D scanner to detect its current position by means of an internal positioning system. This system concurrently performs the scanning process. Closed-loop scanners can achieve high accuracy in object scanning.
• Open-loop scanning handheld 3D scanners lack an internal positioning system. Thus, their scanning accuracy is lower than that of closed-loop scanners. Nevertheless, open-loop scanners are still widely used in various industries because of their affordability.
• Laser scanning handheld scanners employ lasers to measure the distance of the laser points from the scanner. These point measurements are then combined to create a precise 3D model. Laser scanners are well-known for their accuracy in capturing detailed geometric data.
• LIDAR is a laser 3D scanning technique that measures an object's distance from the light-reflecting laser. Handheld LIDAR 3D scanners are efficient for creating textured 3D models in environments where there is substantial lighting interference.

• Texture mapping is the application of image or color to 3D scanned objects. Handheld 3D scanners can also generate texture maps based on the captured color data during the scanning process.
• Post-processing software allows users to refine and clean up the 3D model after it has been scanned. Users can simplify the mesh, add textures, or repair any errors to enhance the model.
• Real-time preview is a feature of handheld 3D scanners that enables users to observe a preview of the scanned 3D model while the scanning procedure is ongoing. This functionality facilitates users in adjusting scanning parameters to optimize the quality of the final 3D model.
• Multiple scan modes refers to the different scanning modes that handheld 3D scanners offer. These modes allow users to adjust scanning parameters and conditions according to specific requirements to get the desired 3D model. Common scanning modes include environmental mode, object mode, and precise mode.
• Color capture is a feature of some advanced handheld 3D scanners that can record the color information of the scanned object. The captured color data is then integrated into the generated 3D model, restoring the actual appearance of the object with the 3D model that includes color data.
• Battery-operated handheld 3D scanners can function by means of an internal battery. Their battery capacity is an essential criterion influencing the time the scanner can operate continuously.
• USB connectivity refers to the capability of handheld 3D scanners to connect to a computer via a USB cable to transfer scan data or receive power. Some models also feature USB ports for connecting external devices like monitors or storage drives.
• Rugged design handheld 3D scanners are built with durable materials. They are shock-resistant and water-resistant. Such scanners are suitable for scanning work in harsh environments.
