When using a 3D scanner, the 'size of the object' and the 'scanning environment' can surprisingly become major challenges.
While small parts are relatively easy to scan, for large objects, people, furniture, or outdoor facilities, it's necessary to stably acquire a wide range from a distance. Furthermore, outdoors, scanning can be affected by sunlight, making it difficult to obtain data with conventional scanning methods.
This is where the VCSEL high-speed scanning mode becomes crucial.
**Features of Revopoint POP 4: Blue Laser & Infrared Hybrid Configuration**
The POP 4 is a hybrid handheld 3D scanner that combines a blue laser with infrared structured light.
It can switch between five scanning modes depending on the application,
covering a wide range from precision parts to large objects and outdoor scanning.
**Five Scanning Modes**
**30-line Cross Blue Laser Scan**
30 cross laser line scans
Achieves high-speed and high-precision scanning.
Suitable for scanning:
Industrial parts
Precision parts
Black objects
Metal surfaces
Complex shapes
**Single Laser Line Scan**
Single blue laser line allows high-precision acquisition of narrow areas such as deep holes and grooves.
This mode is suitable for complex internal structures and detailed scans.
**VCSEL High-Speed Scan**
Projects a high-density dot pattern,
enabling fast and smooth scanning of large objects and outdoor scenes.
Suitable for:
Large workpieces
Outdoor objects
Vehicle parts
Human body scanning
**Full Field HD Scan**
Projects a high-definition structured light pattern,
enabling marker-free scanning for objects with distinctive features.
Allows for smooth modeling while maintaining fine details.
**Hybrid HD Scan**
Combines Full Field HD and VCSEL,
achieving both high-density point clouds and smooth tracking performance.
This mode offers an excellent balance of accuracy and efficiency.
**AI-powered Real-time Object Separation and Tracking (Windows only)**
The POP 4 also supports AI-powered real-time object separation and tracking.
Recognizes objects with a single click and automatically tracks them during scanning.
By automatically removing unnecessary environmental point clouds, it outputs only pure object data.
This achieves:
Reduced post-processing time
Reduced unnecessary data
Improved work efficiency
Supporting a smoother 3D scanning workflow.
**Photorealistic 3DGS Modeling (NVIDIA GPU compatible)**
The POP 4 also supports photorealistic 3DGS modeling utilizing Gaussian Splatting technology.
By combining point cloud data with RGB information, it can generate highly detailed 3D models with realistic textures.
Furthermore, it supports export in .splat format,
making it usable in various digital production fields such as:
Game development
CG production
Animation
VR / XR content
**What is VCSEL mode?**
VCSEL stands for Vertical-Cavity Surface-Emitting Laser.
In 3D scanning, it projects a high-density dot pattern onto an object, and acquires its shape by reading the changes with a camera.
In other words, VCSEL mode is:
A scanning method that projects numerous small light dots onto an object, and analyzes their distortion and positional changes to acquire the 3D shape.
Unlike the blue laser mode which uses line lasers to track fine details, VCSEL is effective for acquiring wide areas at once, making it strong for long-distance, large object, and outdoor scanning.
**Mechanism of VCSEL Mode**
In VCSEL mode, the scanner projects a high-density dot pattern onto the object.
The dots hitting the object's surface change appearance depending on the distance and shape.
The scanner's camera reads these changes, and software reconstructs the 3D shape.
This method offers the following advantages:
Easy to acquire wide areas at once
Easy to maintain distance from the object
Easy to track even large objects
Usable even in bright environments
Especially in outdoor and large object scanning, 'whether sufficient distance can be maintained' significantly impacts work efficiency. VCSEL mode is a very practical technology in this regard.
**Scenes where VCSEL mode is active: Scanning large objects**
VCSEL mode is suitable for large objects because it can efficiently acquire wide areas.
For example:
Furniture
Sculptures
Full human body
Architectural components
Outdoor objects
It can capture objects with a wide field of view, making the overall scanning process smoother.
